中文摘要:研究了中华鲟、达氏鳇、施氏鲟、青鱼、草鱼、鲢、鳙、鲤、赤眼鳟、大眼鳜、鳜、黄尾密鲴、银鲴、花、、团头鲂、尖头塘鳢、鲫等19种淡水鱼类的生态参数(L∞、W∞、K、Tm、Tmax、M、PF)和生活史类型。3种鲟鱼类属k-选择,青鱼、草鱼、鲢、鳙偏向r-选择,其它12种鱼类属r-选择。种群繁殖力PF的数值大体上可反映出某种鱼类的生活史类型,运用Beverton-Holt平衡产量模式估算表明,只有合理控制捕捞强度和起捕年龄,既能保护资源,又能获得较好的经济效益。

外文摘要:Ecological parameters (L∞、W∞、K、Tm、Tmax、M、 PF) and life-history pattern on 19 species of freshwater fishes such as Acipenser sinensis, Huso dauncus, Acipenser schrenckjj,Mylopharygnodon piceus, Ctenopharyngodon idellus, Hypophthalmichthys molitris, Aristichys mobilis, Cyprinus carpio, Squaliobarbus curriculus, Siniperca kneri, Siniperca chuatsi (female), Xenocypris davidi, Xenocypris argentea, Hemibarbus maculatus, Patabramis pekinesis, Megalobrama amblycephala, Eleotris oxycephala, Carassius auratus are studied in this paper. The results indicate that three species of Sturgeon bebong to k-selection,Black,Grass,Cilver carp and Bighead tend to r-selection,and Carp、Curcian carp etc. 12 species,r-selection. By analyzing the value of the population fecunidity (PF)we can see roughly which lifehistory pattern the fish belongs to. The estimate has been done for Beventon-Holt equilibrium output model, and the results indicate that only when the harvesting strength and the first fishing age properly controlled,the resourcs can be protected and a better economic efficience can be gained.
