带鱼Trichiurus haumela(Forsk■l)广分布于渤海、黄海、东海和南海,种群较为复杂,国内外学者已进行过多次研究,但仍需进一步探讨。我们曾在研究中国沿海带鱼的耳石与鱼体相对生长的地理变异的基础上,将中国沿海带鱼划分为四个地理种群,即:渤海-黄海种群:东海北部种群;东海南部-粤东种群及南海种群。本文是对东海南部-粤东种群作进一步的研究。主要依据鱼群各项相对生长指标的差异对栖息于台湾浅滩海域的带鱼种群问题进行探讨。
Trichiurus haumela (Forsk ■ l) is widely distributed in the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea. The population is more complicated and many studies have been conducted by scholars at home and abroad, but further study is needed. Based on the study of the geographical variation of the relative growth of otoliths and fish bodies in China’s coastal octopus, we divided the four coastal marine fish populations into four geographical populations: the Bohai Sea-Yellow Sea population: the northern part of the East China Sea; the southern part of the East China Sea-eastern Guangdong population And South China Sea population. This article is a further study on the population of southern East China Sea-eastern Guangdong. Based mainly on the differences of relative growth indexes of fish stocks, the problem of hairtail population perched in the shallow shoal of Taiwan was discussed.
