Description

SYSTEM AND PROCESS IN MONITORING AQUATIC ANIMALS’ GROWTH AND HEALTH STATUS
Field of the Invention
Engineering or agricultural digital technology as regards systems and processes in monitoring aquatic animals’ growth and health status
Background of the Invention
In the aquaculture industry, with that related to shrimps as an example, monitoring aquatic animals’ growth and health status requires that live aquatic animals be taken out of water in order to measure their sizes and weights together with shrimp food used each day to estimate the produce; check quality, particularly that concerning sizes; and estimate shrimp disease situation inside culture ponds. At present, acquisition of the said findings can be performed with activities of casting nets, then pulling up a number of aquatic animals, and then measuring their sizes and weights as mentioned above. This may result in damage or death of taken aquatic animals as well as fright of others in the proximity, making them stop eating or traumatized.
In addition, in feeding quantity determination for aquatic animals, such as various types of shrimps or fish and so on, particularly the shrimp-type, agriculturists examine check-trays to forecast whether food fed each round is finished by aquatic animals or left in ponds. Check-trays are long-used devices in examining shrimps’ eating. The examination has to be performed every 30-60 minutes throughout feeding duration and can usually be done in daytime because of danger in the said operation at night and possibly insufficient light.
Both above-mentioned activities have limitations, namely use of human labour in sampling, size and weight measurement that requires note taking and labour, aquatic animals’ stress upon being sampled and taken, check-tray lift that uses labour and great effort, check-tray lifting uncertainty because of a limitation as regards labour in comparison to area and the number of check-trays at a given time. All these render aquaculture management inefficient, and inefficient management leads to poor water quality, causing diseases that result in damage of the produce.
After performing patent database searches, some prior inventions relating to monitoring of aquatic animals’ eating or starvation degree of aquatic animals of shrimp and crab types using image-processing systems were found. For example: A Chinese patent application, publication number CN 110089467A, with the invention title ‘Device and method for determining feed sensing abilities of shrimps and crabs’ and a Chinese patent, publication number CN110089467B, with the invention title ‘Apparatus and method for determining shrimp crabs in good feed’ mention devices and processes for determining feedsensing abilities of shrimps and crabs, consisting of a main detecting net for catching shrimps and crabs immersed in the water with sub-nets at different spatial locations for catching individual shrimps or crabs. The top of a food tray, which is on the top of the net, is installed with an underwater camera. Feed-sensing efficiency of shrimps and crabs is checked by counts together with distances from the main detecting net’s centre.
A Chinese patent application, publication number CN 111696114A, with the invention title ‘Recognition method and device for analyzing starvation degree of penaeus vannamei boone based on underwater imaging” mentions a recognition device for analysing starvation degree of Pacific white shrimps based on underwater imaging, consisting of a receptacle, a camera installed at the top of the receptacle, a major light source for lighting and a processor connected with the camera. The processing unit receives shrimp images collected by the camera, determine image peripherals, calculates shrimps’ locomotion speeds and prey quantities following head and tail identification in order to specify shrimps’ hunger levels. This invention can also specify Pacific white shrimps’ starvation degree based on the underwater imaging using shrimp images taken in real time. Shrimps’ starvation degree is considered by experts, leading to recommendations on shrimp feeding and breeding.
An international patent application, publication number W02020250330A1, with the invention title ‘Aquatic animal cultivation assisting system, lift device, feeding device, aquatic animal cultivation method, and aquatic animal cultivation assisting program’ mentions an aquaculture-assisting system that can easily receive data on aquatic animals, such as aquaculture pond shrimps, consisting of a storage unit for images taken from aquaculture ponds using a camera, an image-analysing unit for analysing images taken by an image input unit, and an aquatic animal data input unit for receiving such data related to aquatic animals in culture ponds.
A United States patent application, publication number US20210045364A1, with the invention title ‘ System and method for smart aquaculture’ mentions a smart aquaculture system that consists of a breeding place, a feeder, an underwater camera and a controller connected with the camera and the feeder for underwater images. The controller is primed to calculate leftover food quantity per underwater images or send underwater images to a server that calculates leftover food quantity, and the feeder dispenses food into breeding ponds in correspondence with the calculated leftover food quantity.
Some patents mention aquatic animal calculation or count. For example:
An Indian patent application, publication number IN202121001287A, with the invention title ‘Method and apparatus for monitoring and counting an aquatic organism suspended in aquatic bodies’ mentions a method and an apparatus for monitoring and counting aquatic organisms using the sonar technology, consisting of steps of sonar module determination on a remote-controlled boat, boat launch in pond, boat’s navigation route establishment, scanning and monitoring of aquatic organisms via sonar signals, processing of acquired image data to determine and classify aquatic animals, and aquatic organism identification and counting.
A petty patent application number 1503000107 with the invention title ‘Automatic aquatic animal size meter and weight recorder’ mentions an automatic aquatic animal size meter and weight recorder, having a controller that serves to control the function of aquatic animal size and weight meter, a camera for taking aquatic animal images with light installed on the top of an aquatic animal tray, and a laser spotter to mark aquatic animal position. The aquatic animal tray is on a weighing apparatus. At the beginning of aquatic animals’ data collection, a sedated aquatic animal is placed on the aquatic tray with the animal’s gill cover end positioned at the laser-marked spot for its body’s length and width measurement via camera-taken image for the controller with a body’s length and width calculation program to read the body’s data from a microchip. At the same time, the animal is weighed, and the data on the length, width, weight and image of that aquatic animal are then stored in memory.
It may be seen that the above-mentioned data still have disadvantages as regards working nature, data efficiency and obtained outcomes. For example, A Chinese patent application, publication number CN 111696114A, still has disadvantages in that it only records shrimp images, and the acquired images are only used in one particular way, or a United States patent, publication number US20210045364A1, still is calculation of feeding merely based on leftover food images without mentioning behaviours of aquatic animals in ponds that may cause feeding deviation in real operation. In this invention, however, images can be used for segmentation, object detection and object classifications because there are clear image details recorded from the top view, particularly in daytime. In addition to shrimp images, this invention can measure food quantity fed into the system and check eating rate because food pellets may be seen from images, as well as being able to collect aquatic animals’ eating behaviour data so as to know whether food in pond is sufficient by monitoring the period in which aquatic animals finish food on the pond floor or in the pond and then swim up to eat from a food tray. An international patent, publication number W02020250330A1, still is a device in the form of mere usual check-tray, which requires a lift device for image taking. Upon check-tray lift, shrimps are frightened, and swim away or jump out of the check-tray, rendering obtained images unclear or making it impossible to record all types of aquatic animal images, and the recording is position-located every 24 hours. In contrast, this invention is a floating device on the water surface. Real-time image recording is at the position of the installed device that does not frighten aquatic animals and can record images at all times.
Summary of the Invention
The present invention is related to system and process in monitoring aquatic animals’ growth and health status, consisting of a light box with inside light source installation together with a food tray at the bottom gap area as a food receptacle for drawing aquatic animals in for recording of their images and behaviours. The top of the light box is installed with an image input unit and connected with a control unit in recording aquatic animal images as one or more types of still images or motions or three-dimensional images by receiving instructions from the control unit in the form of continuous real-time image recording per determined duration in order to process via a cloud system using machine learning that consists of at least one or more instruction sets in calculating period in which aquatic animals from pond rise to eat from the food tray, or rate of eating from the container, or right food quantity for aquatic animals, or aquatic animals’ hunger, or aquatic animals’ sizes and weights, or aquatic animals’ quality that may lead to diseases to yield data consisting of at least period in which aquatic animals eat, eating quantity, and aquatic animal sizes, weights and quality. Subsequently, results are displayed through a display device and sent to a pond-feeding system in instructing aquatic animal feeding in pond. The aquatic animal feeding in pond is performed via one or more means of the operator or automatic feeding or the control of the control unit, with aquatic animal-feeding rate adjusted in correspondence with aquatic animals’ growth and health status data processed via the cloud system.
Also included are a buoy connected with the bottom of the light box in facilitating it to float at the water level, and a water quality meter measuring the water quality inside aquatic animal pond and then sending data to the control unit and a processing unit in processing the water quality and in using them to adjust aquatic animal-feeding rate into pond from a pond-feeding system together with growth and health status data processed via the cloud system. This invention aims for development of system and process in monitoring aquatic animals’ growth and health status that can be done at all times whether in daytime or at night without disturbing their living, eating or growth by drawing them into the system for recording of their images and behaviours that are processed as their growth, health status or behaviour data to use as information for appropriate aquaculture, particularly to adjust for the most beneficial feeding quantity and frequency where aquatic animals can eat and utilise for their efficient living and growth with no pond spoilage, which would otherwise lead to pathogens and result in poor water quality.

The following text shows description of the invention with no intention to limit the invention’s scope whatsoever.
The present invention is related to system and process in monitoring aquatic animals’ growth and health status. Figures 1 and 2 show a system for monitoring aquatic animals’ growth and health status, consisting of a light box 1 that serves as a place to install a device for receiving the food from a tray-fed system 20. The interior contains a light source and an image input device for aquatic animals that enter the light box. There is a control unit 5 to control aquatic animal image recording and then send obtained data related to aquatic animals’ growth and health status to process at a cloud system 3. Subsequently, acquired data are displayed through a display device 4, and can be called and seen by the operator 6. Also, the operator 6 can adjust and control the system by giving instructions to the control unit 5.
Particulars of the system for monitoring aquatic animals’ growth and health status are as follows.
The light box 1 is an opaque material in a closed hollow form. For example, the light box 1 can have a pitch-black opaque quality with white ceiling inside and so on. The said light box 1 preferably is a hard and weighty material because it can better endure wind force during use than lightweight materials can. At least one light source 102 is installed at the top inside wall area of the light box 1. The bottom of the light box 1 is arranged with at least two gaps 10 for allowing water to flow from one side to the other, and as doorways for aquatic animals to enter for food.
The food tray (101) is arranged with high edges of 0.5-1.0 centimetre. The said edges are provided as a material with net or airy quality, containing gaps through which water can flow while small-sized food cannot. The food tray (101) is installed at the gaps 10 area of the light box 1 as an aquatic animal food receptacle from a tray-fed system 20 preferably installed at the water surface level or 1-30 centimetres below such level so that aquatic animals may conveniently approach to eat and images may appropriately be recorded.
In an embodiment, the food tray 101 is further composed of at least one bottom gap as a waste or dirtiness drain from the food tray to level below.
The light source 102 is preferably provided as white or orange light with the light intensity between 10-10,000 lux or a light source in the infrared range, such as an infrared lamp and so on, to fit for use in environment with low or limited light. The installation position of the light source 102 should be one that minimises shadows on the food tray 101 for good aquatic animal images’ resolution.
A light sensor 104 is installed outside the light box 1 in metering outside light exposure 200 and delivering data to the control unit 5 in controlling the light source 102.
At least one image input unit 103 is connected with the control unit 5 in recording images and behaviours of aquatic animals that approach the food tray 101 by receiving instructions from the control unit 5 and continuously recording real-time aquatic animal images inside the food tray 101 per determined duration.
In an embodiment, the image input unit 103 is set to record images that may be chosen from one or more types of still images or motions or three-dimensional images. The image input unit 103 is accompanied with a device for enhancing recorded data quality for better record images in different environments. For example, an IR filter or an IR cut, which cuts visible light or light in the wave range of 400-700 nanometres, turns images’ quality to black and white, helping enable higher resolution of recorded images and increasing the processing accuracy.
The control unit 5 is set to control the system function in monitoring aquatic animals’ growth and health status by giving instruction set to the image input unit 103 in image recording and then in delivering aquatic animal images 100 and their behaviours 800 to process via the cloud system 301 by machine learning. The cloud system 301 is capable of processing via the Internet or local area network (LAN) or wide area network (WAN). The processing 303 is set to obtain data consisting of at least period in which aquatic animals eat, eating quantity, and aquatic animal sizes, weights and quality. In an embodiment, the control unit 5 is set to communicate to the cloud system 301 with wireless or wired communication.
In an embodiment, the control unit 5 is set to control the light source 102 to work upon outside light intensity greater than 1,000 lux and control the use of light source in the infrared range upon outside light intensity below 1,000 lux, or the control unit 5 is set to control the function of the light source 102 per light intensity set by the operator 6.
In an embodiment, the control unit 5 is set to deliver aquatic animal images 100 to an aquatic animal image-enhancing unit 501 to enhance images 600 prior to delivering for processing via the cloud system 301.
A pond-feeding system 2 is set to receive processed data from the cloud system 3 in instructing aquatic animal feeding in pond. The aquatic animal feeding in pond is performed via one or more means of the operator 6 or automatic feeding or the control of the control unit 5, where feeding rate is adjusted in correspondence with aquatic animals’ growth and health status data processed via the cloud system 301.
The cloud system 3 is set to import aquatic animals’ growth and health status data from outside database 302, aquatic animal model 304, aquatic animal behaviours 800 and enhanced aquatic animal images 300 by network connection with the control unit 5 in processing and recording aquatic animals’ growth and health status values. Recorded aquatic animal images can be used for segmentation, object detection and object classifications.
The cloud system 3 or the control unit 5 is set to contain at least one or more instruction sets in calculating period in which aquatic animals from pond rise to eat from the food tray, or rate of eating from the container, or right food quantity for aquatic animals, or aquatic animals’ hunger, or aquatic animals’ sizes and weights, or aquatic animals’ quality that may lead to diseases.
The display device 4 is required as an electronic device with a monitor in displaying and recording aquatic animals’ growth and health status data acquired by the processing via the control unit 5 or the cloud system 3, and sends data as messages or images to the operator 6. Examples of the display device 4 are mobiles or computers and so on. The system for monitoring aquatic animals’ growth and health status is further composed of a buoy 7 connected with the bottom of the light box 1 in facilitating the light box 1 to float at the water level.
Also included is a water quality meter 9 in water quality measurement 901 inside aquatic animal pond that delivers data to the control unit 5 and the processing unit 503 in processing the water quality 902 to be used as information in adjustment of rate of aquatic animal feeding into pond from the pond-feeding system 2 together with aquatic animals’ growth and health status data processed via the cloud system 301.
Further included is an electrical system 8 as power supply for the system, where the electrical system 8 may be chosen from one or more types of alternate current system or direct current system or solar cell power supply or solar cell power supply coupled with batteries.
Figures 3 and 4 show the process in monitoring aquatic animals’ growth and health status, consisting of the following steps.
A. Install a light box 1 with installation of at least one light source 102 at its top inside wall. The bottom of the light box 1 is arranged with at least two gaps 10 for allowing water to flow from one side to the other, and a food tray 101 is installed as an aquatic animal food receptacle from a tray-fed system 20.
B. Control for food release onto a container 201 from the tray-fed system 20 and turn on the light source 102 so that the light intensity is between 10-10,000 lux. Subsequently, let aquatic animal samples enter the container 202.
The control of the light source 102 is arranged with a light sensor 104 installed outside the light box 1 in sensing outside light exposure and delivering data to the control unit 5 in controlling the light source 102.
The control unit 5 is set to meter light exposure 200 with the light sensor and then control the light source 102 to work upon outside light intensity greater than 1,000 lux and control the use of the light source in the infrared range upon outside light intensity below 1,000 lux, or control the function of the light source 102 per light intensity set by the operator 6.
C. Set for an image input unit 103 to record aquatic animal images 500 that consist of aquatic animal images 100 and their behaviours 800 inside the light box 1 per conditions determined 100 by the control unit 5. Subsequently, deliver aquatic animal images 100 to a cloud system 301 to process 303.
The image input unit 103 is set to record images that may be chosen from one or more types of still images or motions or three-dimensional images.
Aquatic animal images 100 are delivered to an aquatic animal image-enhancing unit 501 to enhance the images 600 by the control of the control unit 5 prior to delivering for processing via the cloud system 301.
D. Process aquatic animals’ growth and health status 303, consisting of at least one or more types of data on period in which aquatic animals eat, or rate of eating from the container, or right food quantity for aquatic animals, or aquatic animals’ hunger, or aquatic animals’ sizes and weights, or aquatic animals’ quality that may lead to diseases, and display results through a display device 4. In addition, the processing 303 is set to save results in memory 502 inside the control unit 5.
The processing of aquatic animals’ growth and health status with the cloud system 3 is set to import aquatic animals’ growth and health status from outside database 302, aquatic animal model 304, aquatic animal behaviours 800 and enhanced aquatic animal images 300 by network connection with the control unit 5 in processing, comparing and recording aquatic animals’ growth and health status values.
The processing of aquatic animals’ growth and health status requires that the cloud system 3 or the control unit 5 contain at least one or more instruction sets in calculating period in which aquatic animals from pond rise to eat from the food tray, or rate of eating from the container, or right food quantity for aquatic animals, or aquatic animals’ hunger, or aquatic animals’ sizes and weights, or aquatic animals’ quality that may lead to diseases.
E. Display aquatic animals’ growth and health status data acquired from D by delivering to the display device 4 and a pond-feeding system 2 to adjust aquatic animal-feeding rate in correspondence with their growth and health status processed via the cloud system 301.
The control of pond feeding 21 is achieved by instructing the pond-feeding system 2 to feed via one or more means of the operator 6 or automatic feeding or the control from the control unit 5. Display of aquatic animals’ growth and health status data through the display device 4 requires that the display device 4 be an electronic device with a monitor in displaying and recording acquired aquatic animals’ growth and health status data, or sending the data to the operator 6. Examples of the display device 4 are mobiles or computers and so on. In an embodiment, a sample behaviour of aquatic animals 800 is period in which they finish food in pond and then swim up to eat from the food tray 101 in each of their feeding rounds and so on. It is a factor indicative of the appropriateness of food quantity fed to aquatic animals in each round, allowing for the operator 6 to modify feeding rate in terms of quantity and frequency to fit for aquatic animal conditions in each pond or for automatic adjustment via installed instruction set.
The process in monitoring aquatic animals’ growth and health status is further composed of water quality measurement 901 with water quality meter 9. Data are then delivered to the control unit 5 and the processing unit 503 in processing the water quality 902 and saving it in memory 502 to be used as information in pond-feeding control by the pond-feeding system 2 together with aquatic animals’ growth and health status data processed via the cloud system 301.
Any improvement may be understood clearly and made by experts in this field. This may fall under this invention’s scope and intention as presented by the attached claims.
