| 摘 要： | 本文研究了1994年福建近海底拖网渔船主要捕捞对象－带鱼，白姑鱼，二长棘鲷，短尾大眼鲷和条尾绯鲤5种底层和近底层鱼类的种群结构，生长和死亡参数及其开发比率，与1976年比较，带鱼渔获的最大年龄由1976年7龄降至1994年的4齿，白姑鱼，二长棘鲷和短尾大眼鲷由1976年或1982年的5龄降至1994年的3龄,条尾绯鲤由1976年的5龄降至1994年的4龄，带鱼的捕捞死亡系数由1976年的0．491上升到1994年的0．956。二长棘鲷由0．340上升到1．273，短尾大眼鲷由0．505上升到0．868。条尾绯鲤由0．576上升到0．924，白姑鱼由1982年的0．235上升到1994年的0．789，开发比率均比1976年或1982年有较大提高，分别在0．495，0．706，呈现充分开发或过度利用，并讨论了种群变动原因，捕捞结构和底拖网捕捞力量调整及5种鱼类的最小可捕标准问题。

| Abstract: | This paper studies the population structure and the parameter of growth and mortality and the exploitation rate of Trichiurus haumela, Argyrosomus argentatus, Parargyrops edi- ta, Priacanthus macracanthus and Upenus bensasi in the coastal waters of Fujian during 1994 ~1995. They are benthic species and subject to bottom trawling. The results are as follows. The fishing maximum age of T. haumela was at age 4 in 1994, and age 7 in 1976, A. argen- tatus, P. edita and P. macracanthus age 3 in 1994, and age 5 in 1976 (or 1982), U. bensasi age 4 in 1994, and age 5 in 1976. The fishing mortality coefficient of T. haumela has rised from 0. 491 in 1976 to 0. 956 in 1994, P. edita from 0. 340 to 1. 273, P. macracanthus from o. 235 in 1982 to 0. 789. The exploitation rate ranged from 0. 495 to 0. 706. They have obvi ously increased as compared with 1976 (or 1982), indicating a full exploitation or over ex ploitation. The cause of population fluctuation and the fishing structure and the adjustment of fishing efforts of bottom trawling and the problem of minimum fishing standard of five species of fishes are also discussed. |
