厦门白哈礁人工鱼礁拟投海域渔业资源调查

根据2014年5月在厦门白哈礁人工鱼礁拟投海域及对照海域开展的本底调查所获的渔业资源资料,对人工鱼礁拟投海域和对照区渔业生物的种类组成、数量分布、优势种和多样性等进行了分析研究。调查共鉴定出渔业生物23种,其中笼壶作业12种,刺网作业20种,渔获种类均以蟹类为主。笼壶作业平均生物量为16.34g/(h·10笼),刺网作业平均生物量为37.00g/(h·片)。综合笼壶作业和刺网作业的调查结果,拟建礁区及周边海域春季渔业资源经济种类少、渔获比重小,生物种类多样性水平低,渔业资源结构总体质量较低。

Fisheries resources survey of Xiamen Baihajiao Waters

Based on data from fisheries resources background survey in Baihajiao waters as well as con‐trol area in Xiamen in May 2014 ,the species composition of fisheries organisms ,stock density distribu‐tion ,dominant species and community diversity were analyzed .23 species were collected in the sur‐vey ,in which 12 species were caught by cage pot fishery ,20 species by gillnets ,in which the main spe‐cies were crabs .The average biomass was 16 .34 g/(h · 10 cage) by cage pot fishery ,and 37 .00 g/(h · net) by gillnets .The results indicated that ,in spring in these areas there were less economic spe‐cies and their proportion in fishing catch were small .Both the biological diversity level and overall quality of the fishery resources structure were low .
