本計畫賡續過去的深海漁業資源調查試驗,積極投入深海未利用資源的技術開發、深海生物特性及漁場環境形成機制等方面的研究。現階段的重點之一即為櫻蝦及菱鰭魷等資源的調查開發及加工利用研究,短期內將進一步促成產銷班的成立,使該項珍貴的資源能夠在省人力、省能源的情況下順利產、銷,繼而達成永續利用的目標。

研究報告摘要(英)


The present study is an extension and continuities of our previous study on deep-seafishery resources. The main purpose is to establish basic information for the speciesidentification, ecological conservations, exploitation of resources, etc., of the macrurandecapods and deep-sea cephalopods. The sonar sounding records of the present studyshow that the sakura shrimp (Sergia lucens) is distributed in the waters around the GueishanIslet and undertakes an apparent diurnal vertical migration. The resources areestimated to 333 metric tons.On the other hand, the sex of Thysanotheuthis rhombus may be distinguished visuallygreater than 250mm ML. The sexual ratio shows that the males are more than femalesaround the year, except January to March. Testis maturation has been observed in maleat 250-350mm and ovary maturation in female at 500-650 mm. The smallest maturefemale observed was 500mm ML, and the majority mature at 550-650mm ML.Spermatophores of male beginning from 570mm ML, and majority mature 650mm ML.
