东海黄鳍马面鲀生物学特性和资源利用状况

The biological characteristics and resource status of the yellow-fin filefish in the East China Sea

本文着重阐述东海黄鳍马面的生物学特性，计测若干形态性状和差异比较。指明东海与南海的黄鳍马面系两个不同的群系。其次，从饵料生物种类组成、出现频率、摄食强度变化等方面情况反映，黄鳍马面主要以小型浮游生物为食，产卵前又往往处于旺盛状态，这些多与跟它相近似鱼类的适应习性一致。在繁殖上，１００ｍｍ以上（１龄）的个体基本成熟。年龄与生长方面：１龄鱼平均为１０２．７０ｍｍ、２２．７５ｇ，２龄鱼和３龄鱼分别为１３２．７０ｍｍ、５６．９０ｇ和１５０．００ｍｍ、８８．２０ｇ。另外，结合生产统计资料，分析和探讨了黄鳍马面的资源状况。

The yellow-fin filefish distributing in the East China Sea is a stock different from that in the South China Sea. Yellow-fin filefish feeds mainly on plankton, and more actively before spawning. It usually gets mature in about 100 mm, body length(1 year old). The relationship between growth and age is 102.7 mm, 22.75 g-1 year old, 132.7 mm, 56.90 g-2 year old and 150.0 mm, 88.20 g-3 year old, respectively. According to both the biological characteristics and the catches of the fishery in recent years, the stock of this species is obviously in a poor condition.
