摘要
2018年4月至2021年10月,对汤河国家湿地公园鱼类资源开展了调查。结果表明,收集到鱼类23种,隶属于4目7科22属。其中鲤形目16种,占总种数的69.56%,鲈形目4种,鲇形目2种,分别占总种数的17.39%和8.69%,合鳃目1种,占总种数的4.36%,以鲤科种属最多,14属15种,占比65.22%;鱼类可划分为中国平原区系复合体、晚第三纪早期区系复合体、南方平原区系复合体和北方平原区系复合体。对鱼类种群特征、影响鱼类资源的因素等进行了分析。提出,为了更好地保护恢复鱼类资源,应优化增殖种类;规范鱼类引种;打击非法捕鱼;截污,保证下游汤河生态流量;增放人工鱼巢,提高幼鱼种群量;科学动态监测,维护汤河国家湿地公园生态系统的多样性、稳定性和持续性。
From April 2018 to October 2021,the fish stock in Tanghe National Wetland Park was surveyed.The results showed that 23 fish species were collected,belonging to 4 orders,7 families and 22 genera.Among them,there are 16 species,accounting for 69.56%of the total species,4 species and 2 species,accounting for 17.39%and 8.69%respectively,and 1 species,accounting for 4.36%of the total species and 15 species,accounting for 65.22%;Fish can be divided into China plain fauna complex,late Tertiary prostronomic complex,Southern plain flora complex and Northern plain flora complex.The characteristics of fish populations and the factors affecting fish resources were analyzed.It is proposed that,in order to better protect and restore the fish resources,the proliferation of species should be optimized;Standardize the introduction of fish;combat illegal fishing,intercept pollution;ensure the ecological flow of downstream Tanghe River;increase artificial fish nests and increase the population of young fish;Scientific dynamic monitoring to maintain the diversity,stability and sustainability of the Tanghe National Wetland Park ecosystem.
