【摘要】：鰹魚作為一種重要的漁業(yè)資源,影響到成千上萬人的生計問題。全球漁業(yè)資源的匱乏和人類的過度捕撈導(dǎo)致鰹魚的漁獲量不再能夠滿足人們的需求,人們需要知道鰹魚的生態(tài)狀況,從而進行有效的鰹魚資源保護,并為漁民提供資源的預(yù)報。傳統(tǒng)生態(tài)調(diào)查的方法都需要耗費大量的人力物力,漁業(yè)水聲學(xué)的發(fā)展使其在生態(tài)調(diào)查中成為一種主要手段,目前較常用的水聲學(xué)方法有聲吶探測技術(shù)和超聲波生物遙測技術(shù)。超聲波生物遙測技術(shù)是基于對水生生物的行為和生理研究的迫切需求被開發(fā)出來的,目前已經(jīng)成為對海洋生物生態(tài)調(diào)查研究的主要手段之一。本研究用回收式被動監(jiān)測型超聲波生物遙測系統(tǒng),對與那國島附近海域的鰹魚進行監(jiān)測,這種方法需要在調(diào)查海域設(shè)置接收機,所以本研究利用了調(diào)查海域眾多用于集魚的浮魚礁,在這些浮魚礁上設(shè)置接收機,研究鰹魚在浮魚礁之間的活動情況,通過兩個月的數(shù)據(jù)收集,得到了詳細的鰹魚活動信息。在處理過程中,又編寫了處理程序,提高了數(shù)據(jù)處理效率。但是這種方式存在不能及時傳輸數(shù)據(jù)的缺陷,所以,在此基礎(chǔ)上,又設(shè)計了可以無線傳輸信息的通信式被動監(jiān)測系統(tǒng),經(jīng)過試驗,得到了準確有效的數(shù)據(jù)。這種新的方法不僅可以大范圍長時間的監(jiān)測鰹魚的活動,更能夠及時將數(shù)據(jù)傳輸?shù)交?極大的提高了生態(tài)調(diào)查的效率。同時,這種方法還可以在更多洄游性水生生物的生態(tài)調(diào)查中運用。
[Abstract]:The bonito fish, as an important fishery resource, affects the livelihood of thousands of people. The lack of global fisheries resources and human overfishing have caused the catch of bonito fish no longer to meet the needs of the people. People need to know the ecological conditions of the bonito fish, so as to protect the resources of the bonito and provide the resources for the fishermen. The traditional ecological investigation method needs a lot of manpower and material resources. The development of fishery acoustics has made it become a major means in the ecological investigation. At present, the most commonly used acoustic methods include sonar detection and ultrasonic biological telemetry. The ultrasonic biological telemetry technique is based on the behavior and physiology of aquatic organisms. The urgent demand has been developed and has become one of the main means to investigate the marine biological ecology. This study uses the passive monitoring ultrasonic biological telemetry system to monitor the bonito fish in the sea area near the island. This method needs to set the receiver in the sea area, so this study uses the adjustment. There are many floating fish reefs used for fish collecting, set up receivers on these floating reefs and study the activities of bonito fish on Floating Fish reefs. Through data collection of two months, detailed information on the activities of bonito fish is obtained. In the process of processing, the processing program is written to improve the efficiency of data processing. But this way is not timely. On the basis of this, a passive monitoring system with wireless transmission information is designed, and the accurate and effective data are obtained through experiments. This new method can not only monitor the activities of the bonito fish for a long time, but also transmit the data to the base station, which greatly improves the ecological investigation. At the same time, this method can also be used in the ecological investigation of more migratory aquatic organisms.
