摘要
基于2013—2022年春季和秋季在海州湾及其邻近海域进行的渔业资源调查数据,综合考虑鱼类的种类组成、耐受程度、营养结构、繁殖习性等生态参数和属性,采用鱼类生物完整性指数(Fish-index of biotic integrity,F-IBI),评价了海州湾生态系统健康状况及其变化趋势。结果表明,海州湾春季和秋季的鱼类生物完整性指数各保留8个评价指标。海州湾春季和秋季的F-IBI得分分别为18~51和24~54。从健康等级来看,春季海州湾生态系统基本在“一般”及以上水平,秋季海州湾则在“一般”上下波动。总体上,春季海州湾生态系统的健康状况较好,鱼类生物完整性指数在波动中呈逐渐下降的趋势。整体来看,海州湾鱼类资源状况不佳,高耐污鱼类和杂食性鱼类所占比例有所增加,渔业资源承受过度捕捞、气候变化等多方面的压力,亟须采取科学有效的措施保护和修复海州湾的渔业资源及生态系统。
Based on the fishery resource survey data collected in Haizhou Bay and its adjacent waters in spring and autumn from 2013 to 2022,we evaluated the statement and change trend of the ecosystem health of Haizhou Bay using the fish-index of biotic integrity(F-IBI),considering many ecological parameters and attributes such as fish species composition,tolerance,trophic guild,and reproductive guild.The results showed that eight metrics were retained as F-IBI of Haizhou Bay in each season.The F-IBI scores of Haizhou Bay in spring and autumn ranged from 18 to 51 and from 24 to 54,respectively.The ecosystem of Haizhou Bay was basically at"fair"or above levels in spring,while fluctuating around"fair"level in autumn.Generally,the health statement of Haizhou Bay ecosystem in spring was better,and the F-IBI scores showed a gradually decreasing trend in fluctuation.The condition of fishery resources in Haizhou Bay were poor,with an increased proportion of tolerance and omnivorous fish species.Fishery resources in Haizhou Bay were under various pressures such as overfishing and climate change,and scientific and reasonable measures should be taken to protect and restore the ecosystem of Haizhou Bay.
