摘要
根据 1998年 7月至 2 0 0 0年 6月在闽南、台湾浅滩渔场开展二长棘鲷 (Parargyropsedita)资源的专题调查研究资料 ,本文研究了二长棘鲷群体数量在该渔场的时空分布 ,全年以 6～ 9月索饵群体的分布密度最高 ,分布的范围也最广泛 ,主要分布在 2 3°0 0′～ 2 4°0 0′N ,117°30′～ 119°0 0′E ;4～ 5月以后幼鱼群体开始大量出现 ;6～ 8月索饵群体广泛分布于闽南、台浅渔场中北部近岸海区 ,而 1～ 3月生殖群体集中分布于该渔场近岸浅水区及澎湖周围海域 ;全年捕捞主要以当年生的索饵群体为主。
According to the investigation data of utilization on resources of Parargyrops edita Tanaka in Minnan-Taiwan bank fishing ground during July 1998 to June 2000,this paper studied its distribution in time and space,the breeding population density is the highest during June to September, and the range of distribution is also wide,it mainly distributed in 23°00′～24°00′N, 117°30′～119°00′E;A lot of juvenile fish began to appear in April and May, the breeding population widely distributed in the coastal waters of middle and northern Minnan-Taiwan bank fishing ground during June to August,and the spawning stock distributed in neritic waters and surrounding sea of Penghu during January to March. The breeding population was dominant in the catch.
