Study on Remote Monitoring System for Fish Activity and Water Quality Environment in Offshore Fish Cage

Abstract

在全球海洋渔业资源日益衰减的今天,深水网箱以其抗风浪、耐海流能力强、养殖容量大、高产高效、环保等优势成为现代耕海牧渔的发展方向。深水网箱养殖过程中,由于网箱离岸远,范围广,水体浑浊,不容易观察鱼群活动状态,同时也往往难以把握合适的投饲量,投饵过少将影响鱼类生长健康,过多则增大养殖饲料成本,同时剩余饵料又会污染环境。为了进行鱼群状态监测和避免饲养投喂的随意性和盲目性,急需加强深水网箱鱼群状态与水质环境监测,为正确判断鱼群食欲、科学进行投饲提供重要参考依据。本文根据深水网箱养殖环境的特殊要求,设计并实现了一套结构简单、功耗低、体积小、远程、实时的深水网箱鱼群状态与水质环境监测系统。 主要内容: ...The global marine fishery resources are going downhill nowadays. Fish culturing in offshore fish cage is being the developing trend of marine aquaculture for its advantages of great resistance to wind, waves and strong-flowing currents, large breeding capacity, high yield and high efficiency. However, it is difficult to grasp the appropriate amount of feeding, feeding little would affect the growt...学位:理学硕士院系专业:海洋与地球学院_海洋物理学号:2232013115144
