Abstract

In this study, the IoT sensor technology required for improving the survival rate and high-density productivity of individual shrimp in smart shrimp farming (which involves the usage of recirculating aquaculture systems and biofloc technology) was analyzed. The principles and performances of domestic and overseas water quality monitoring IoT sensors were compared. Furthermore, the drawbacks of existing aquaculture monitoring technologies and the countermeasures for future aquaculture monitoring technologies were examined. In particular, for farming white-legged shrimp, an IoT sensor was employed to collect measurement indicators for managing the water quality environment in real-time, and the IoT sensor-based real-time monitoring technology was then analyzed for implementing the optimal farming environment. The results obtained from this study can potentially contribute to the realization of an autonomous farming platform that can improve the survival rate and productivity of shrimp, achieve feed reduction, improve the water quality environment, and save energy.

RAS(Recirculating aquaculture system) 방식 또는 바이오플락 기술를 사용한 흰다리 새우의 육상 양식을 통해서 새우 개체의 생존율과 고밀도 생산율을 향상시키기 위한 양식의 원리 및 장치 구성, 국내외 수질 모니터링 센서, 현재의 양식 모니터링 시스템의 문제점 파악 및 미래의 양식 모니터링을 위한 대책을 분석 하였다. 흰다리 새우 양식을 위해서는 수조별 온도, pH, DO, 염도 측정이 기본적으로 필요하며, 암모니아성 질소, 질산성 질소, 아질산성 질소, 생장 관리를 위한 이온성 물질의 측정이 필요하다. 특히 센서재질에 있어서는 SUS304도 부식이 되는 고염도 환경에서 견딜수 있어야 하며, 고탁도 및 부유물질에 의한 생물 부착에 견딜 수 있는 센서가 사용되어야 한다. 또한 내구성 및 측정값 신뢰도, 가격 경쟁력 있는 센서 및 시스템 공급이 필요하다. 바이오플락 양식 환경에서는 고염분, 고부유물 환경에서 견딜 수 있는 센서의 내구성과 데이터 안정성, 신뢰도가 무엇보다 중요하다. 향후 흰다리 새우 및 수산 양식을 위한 최적 양식환경을 확보하기 위해서는 양식 생육 환경 현장의 수질을 측정하고 적정 환경을 결정하며, 자동제어 시스템을 이용하여 제어하고 축적된 데이터를 활용 및 분석하여 지능적으로 관리하는 기술을 개발하는 것이 필요하다.
