Description

Real-time Fishery Environment Information Acquisition System}

The present invention relates to a system for acquiring real-time fishery environment information, and more particularly, by installing a water quality measurement sensor for real-time monitoring of the marine environment of the fish farm and the area around the fish farm, and It relates to a real-time fishery environment information acquisition system capable of providing predictive information necessary for aquaculture by integrating and analyzing the measured data.

In Korea, three sides of the topography are in contact with the sea, so it has a lot of economic effect from the nearby ocean.If such marine resources are polluted or temperature changes, it is possible to directly or indirectly affect the surrounding climate and living environment. It is reality.

In addition, land soil flows into the nearby ocean due to national land development and industrialization, or various environmental pollutants are introduced or dumped, causing marine pollution.

Due to such topographical conditions of Korea, the sea, especially the surrounding marine environment, is directly or indirectly closely related to real life, and if polluted, it will have a great impact on the health of the people and the national economy.

Depending on the marine environment, the ocean water temperature, dissolved oxygen, salinity, pH, turbidity, and solar radiation are largely affected.The recent climate change and local low-water temperature phenomena cause a large amount of death of aquaculture organisms in aquaculture farms and fishes. The reality is that there is no early warning and no response is possible, and measures to minimize damage to domestic cage farming and fishing boat fishing are needed by monitoring and promptly delivering rapid changes in water temperature.

In addition, in the aquaculture industry, the amount of dissolved oxygen dissolved in an appropriate amount of water is insufficient due to excessive feed feeding and high-density farming to promote growth, causing damage to fish in the farm and insufficient oxygen supply to the bottom layer. Therefore, there is a problem in that microorganisms cannot be activated, and as the possibility of group mortality of seaweed and shellfish increases due to the influence of phytoplankton, a problem of salinity occurs.This is a problem in the reproductive organs of fish because the formation of microorganisms is not well when the salinity is high. It occurs, and the lower the pH in the seawater of the farm, the more acidic the water is, and when the sea becomes acidic, it becomes difficult for coral habitats and organisms to live.

In addition, household sewage, factory wastewater, livestock wastewater, etc., among them, household sewage that is thrown away at home is a major problem.Food wastes, synthetic detergents, and manure are included, so these substances reduce turbidity, eutrophication, and lack of oxygen in the water. Because the turbidity sensor increases the amount of pollutants, the amount of light transmitted decreases, and the sensor measures the amount of transmitted light to determine and maintain the appropriate turbidity in the farm. If the amount of insolation in the ocean is insufficient, the main cause of the red tide The red tide is transformed into a lobular imitation that is toxic to aquatic organisms and humans, and the activity of fish is weakened by the influence of the cold water in the aquaculture farm, causing damage from the red tide.To minimize the damage to fisheries from serious red tide, monitoring of red tide It is necessary to establish a system and operate a red tide situation room for prompt information collection, notification, and response when a red tide occurs.

Clean management of the surrounding marine environment is important to fundamentally prevent the inflow of soil from the land, the inflow or dumping of various environmental pollutants, but due to natural influences such as temperature changes caused by global warming and unavoidable circumstances. In some cases, the marine environment may change seriously.

In order to check the water temperature, dissolved oxygen, salinity, Ph, turbidity, and solar radiation of the marine environment, the condition of the surrounding marine environment or the marine environment in a designated specific region is investigated and appropriately responded. Conventional marine-related sensors are operated by exposing the sensor and the cable connected to the sensor to the seawater in a fixed state, and foreign substances such as various floating objects and barnacles generated in the seawater are attached to the sensor and the cable, causing the sensor to malfunction within 2-3 months. There is a problem that it is difficult to accurately measure due to the occurrence of cases and contamination of the sensor.
