摘要

本研究将臺東縣成功沿海捕撈的二種龍蝦養在試驗池中觀察它們的成長，依據成長的變化，檢討目前法定最小捕撈體型是否適用於各種龍蝦，並討論龍蝦保育的策略。試驗時間為一年，其間Panulirus ornatus成長較P.homarus快。以頭胸甲長每5 mm做體型分級，比較各級龍蝦每星期的成長率，P.homarus的成長率在頭胸甲長66-70 mm級突然大幅降下。在P.ornatus這種成長率大幅降下的情發生在頭胸甲長106-110 mm級。這種成長速度大幅降低的現象是因為能量大量應用於生殖系統的發育，而減緩了肉體的成長。當P.homarus的頭胸甲長61-65 mm與P.ornatus的101-105 mm時，體長分別約為17.4與25.4 cm。由此可知法定的最小捕撈體型20cm並不適用於某些種龍蝦。為了挽救已極度開發的龍蝦資源，本文建議可限量捕撈小龍蝦苗養殖，捕撈年老的龍蝦，禁止捕撈生殖力旺盛的青壯年龍蝦。

In this study two species of spiny lobster caught along the coast of Taitung Taiwanwere reared in the experimental ponds to examine the suitability of current minimum legalfishing size of lobsters living off the coast of Taiwan.During the experiment,Panulirusornatus grew faster than P.homarus.A dramatical decrease of growth rate occurredbetween 61-65 and 66-70 mmCL size class of P.homarus(about 17.4 cm body length),and between 101-105 and 106-110 mmCL size class of P.ornatus(about 25.4 cm bodylength)respectively.Changes in growth rate signified a shift in energy use at onset ofmaturation.For allowing a greater proportion of lobsters to mature prior to harvest,it isapparent that current minimum legal size(20 cm body length)is not suitable to some spinylobster species.For resource reservation,it is suggested allowing to collect young juvenilesfor culture and to harvest aged populations,and prohibiting to catch adult populationof active reproduction.
