Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to an anesthesia, dormancy, keep-alive and transportation integrated workstation and a working method for epinephelus malabaricus.
Background
The giant grouper is a new species grouper bred by artificial breeding and adopting the hybridization of a Longquan grouper (male) and a brown spot tiger grouper (female). The pearl giant grouper has more tender and delicious meat quality due to the hybrid advantages, inherits the advantages of strong anti-anisotropy and high growth speed, and can be cultured in modes of ponds, net cages, factories and the like. The pearl, gentian and macula belong to the fierce carnivorous seawater fishes, the mutual cannibalism phenomenon can happen to fish fry over 2cm in total length, the breeding density is too high, the fish bodies are too close to each other, and the mutual attack can be caused, so the common injuries of body surface fish scale loss, skin rupture, subcutaneous blood seepage and the like of the fish bodies are caused.
On the other hand, the pearl giant grouper belongs to high-end aquaculture and is sold almost in a fresh and alive mode, so that the living body is required to be transported to a sales site. The grouper culture site is provided with a shore-based factory, offshore and open sea cages, the culture production area is distributed in two areas, the keep-alive habits are different, and the requirements on the keep-alive transportation are different. Particularly, sea and land relay is needed in the transportation of seawater cage culture, the transportation distance is longer, the time consumption is longer, and the requirement on the keep-alive technology is higher. The traditional keep-alive transportation mode adopts the mode of directly fishing out fish bodies from a culture pond, putting the fish bodies into a live water tank filled with fresh seawater, and cooling, aerating and oxygenating the water bodies in the tank in the transportation process. The method is only suitable for short-distance transportation, and the method cannot be applied to groupers cultured in seawater cages. The mode of independently bagging to keep alive after anesthesia dormancy is adopted for transportation which is mostly adopted at present. However, the method is complicated in operation and steps, needs more equipment and operators, can be put into use only by building a special ship or modifying the ship, but cannot be used in non-cultivating fishing seasons, and is low in input-output ratio.

When the fish body damage distinguishing and screening device 5 is in operation: after a fish body enters the system through a front-section conveying pipeline, different body side position images of the fish body are shot through an upper camera 5a distributed on the outer side of a transparent pipe wall, the fish body images shot by the camera are converted into HSV (Hue, Saturation) color spaces from RGB (red, green, blue) color spaces (the value ranges of HSV are respectively H ═ 0,179 [ (] H [ (] 0,179 ])]；S＝[0,255]；V＝[0,255]) Taking value at a calibrated value [ H ]low,Hupper],[Slow,Supper],[Vlow,Vupper]The value of the pixel point within the range is changed to 255, whichThe value of the remaining pixel point is changed to 0. Noise is reduced through morphological operation of expansion and corrosion, the area of a communication domain formed by 255 pixels is calculated, when the area is larger than a set threshold value, the communication domain is judged to be a serious bleeding injury part, the fish is considered to be seriously injured (not suitable for keep-alive transportation), and the bypass flow is screened out through a bypass of an auxiliary fishway outlet of an upper three-way fish suction pump 402 at the rear; the normal fish body is continuously conveyed into the subsequent operation pipeline through the main fishway outlet of the upper three-way fish suction pump 402.
When the fish body state judging and screening device 6 operates: the system is preset with a fish anesthesia effect determination mode and a fish physiological state determination mode, can determine the fish body after electric anesthesia, the fish body state in the daily culture or the keep-alive process, and mainly determines whether the stripe body color changes.
Judging whether the color of the speckles changes: then the fish body gets into one section level and arranges transparent ya keli pipeline, shoots different position grouper images through the machine vision camera in the pipe wall outside to shoot the image with the anterior segment and carry out the contrast.
In the image contrast method: converting the front section and the shot image into a gray-scale image, binarizing the gray-scale image through a set threshold value, converting the pixel value of black stripes on the grouper body into 255, and converting the rest pixels into 0 which is respectively marked as m and n;
if n/m > p (p is a calibration value obtained by experiment, and is an average value of the ratio of n to m obtained by taking a large number of images of the groupers which are not anesthetized and are confirmed to be anesthetized), the fish body is conveyed back to the spiral pipeline A403 through the spiral pipeline B405 to be secondarily supplemented with electric anesthesia;
if n/m is less than or equal to p, the fish body is conveyed to the next step through a pipeline for re-judgment.
And fourthly, judging whether the fish body moves (namely a re-judging link of the previous step): in the step, the relation between the motion state of the fish body and the water flow speed is automatically judged by machine vision in the whole process, and in the step:
if the motion state of the fish body is not matched with the water flow speed, the fish body is determined to be still moving, and the fish body is sent back through the bypass pipeline and is subjected to the sedation electric anesthesia step and the deep electric anesthesia step again;
if the fish body only moves along with the water flow, the fish body can be determined to enter a deep dormant state, and then the fish body is output.
In the step of judging whether the fish body moves, a machine vision camera is adopted to capture and judge whether the fish body moves, a gray scale image is converted into a binary image by an OTSU global threshold method, the pixel value of the divided fish body is set to be 255, the background of the rest water body is 0, a small connected domain of interference is eliminated by using methods such as morphological processing and filtering, the minimum external rectangle of the connected domain is calculated, and the center point, the length, the width and the rotation angle of the minimum external rectangle of the connected domain formed by the pixels with the value of 255 in a continuously shot multi-frame gray scale image are compared.
When the central point deviation of continuous frames is obviously inconsistent with the water flow speed and the length, width or rotation angle change is larger than a set threshold value, the fish body is determined to be still active, the deep anesthesia can be determined not to be achieved, and the fish body is sent back through a spiral pipeline B405 and is subjected to the sedation electric anesthesia step and the deep electric anesthesia step again;
when the central point deviation of continuous frames basically accords with the water flow speed, and the change of the length, the width and the rotation angle is smaller than the set threshold value, the fish body is determined to move only along with the water flow, no redundant activity is caused, the stiff state is maintained all the time, the fish can be judged to enter deep anesthesia, and then the fish body is output through the auxiliary fishway outlet of the lower three-way fish suction pump 406, so that the anesthesia operation is completed.
