摘要
鮸(Miichthys miiuy)是近海温水性底层鱼类,广泛分布于日本、韩国及中国沿岸海域,而我国浙江、江苏近岸海域为该物种的主要产卵区。调查表明:2003年以来,中国浙江、江苏近岸海域鮸资源量呈逐年上升趋势,且其人工繁殖与养殖产业在我国南方沿海正蓬勃发展,鮸有望成为深水网箱养殖的优良品种之一。为了后续更合理地开发和利用该物种,通过整理前人对鮸多方面的研究,从渔业产量、渔业生物学等方面进行了总结。研究认为:(1)目前鮸的主要捕获海域仍然集中在浙江、江苏近岸海域,产量在采取伏季休渔养护等措施后显著上升,近5年保持在5.8×10^4~7.0×10^4 t。(2)鮸的生长发育受水温、盐度影响。目前对浙江及江苏沿岸鮸的生长、摄食、繁殖等方面有着较为全面的研究,但对其年龄生长、洄游路线、种群结构及资源状况的评估与管理工作亟待开展研究,而对该资源状况进行准确评估可以更好地实现资源的可持续利用。研究建议立即在东黄海海域开展每年定期的渔业调查、采集足够的生物学样本,对其年龄生长、摄食、繁殖特性进行长期监控,以便更好为渔业生产、渔业资源管理提供科学依据,为中国今后在近岸海域合理开发利用该资源提供相关依据。
Miichthys miiuy,a substratum fish of near-sea temperature water,is widely distributed in the coastal waters of Japan,South Korea and China.The coastal waters of Zhejiang and Jiangsu provinces are the main spawning areas of M.miiuy.Studies show that since 2003 the resorce amount of M.miiuy in the area has been rising year by year,and the artificial breeding and aquaculture of M.miiuy in China’s southern coast has been booming,M.miiuy is expected to be one of the best species bred in offshore cages.In order to develop and utilize this species more rationally,this paper summarized the previous studies on M.miiuy from the aspects of fishery yield,basic biology and so on.Results are as follows:(1)The main capture areas of this species are still concentrated in the coastal waters of Zhejiang and Jiangsu provinces,and the yield has increased significantly after the adoption of measures such as fishing suspension and conservation in the summer.In recent 5 years,the yield in those areas has remained at about 5.8×10^4-7.0×10^4 t;(2)The growth and development of M.miiuy are influenced by water temperature and salinity.At present,there are comprehensive studies on its growth,feeding and reproduction along the coast of Zhejiang and Jiangsu provinces,but it is urgent to conduct the study on its age growth,migratory route,population structure and resource status assessment and management.In order to provide scientific basis for fishery production and fishery resource management,it is recommended that regular annual fishery surveys should be carried out immediately in the East China Sea and the Yellow Sea to collect sufficient biological samples,and to monitor its age growth,feeding and reproductive characteristics in the long term.This paper could provide relevant basis for the rational exploitation and utilization of M.miiuy resource in the coastal waters of China.
