【摘要】 1992年7月至1993年6月从闽南、台湾浅滩渔场单拖作业渔获物中随机取样测定条尾绯鲤Upeneus bensasi 1,175尾,其叉长分布55—180mm,优势叉长100—130mm,体重分布4—114g,优势体重10—40g,年龄构成由0—Ⅵ龄组成,以1龄组居多,占40.5％。生长参数L_o=201.91mm,W_o=121.71g,K=0.2010,t_o=-3.2414。种群存活率、年总死亡率、瞬时总死亡率、瞬时自然死亡率及瞬时捕捞死亡率分别为0.3630、0.6370、1.0134、0.3351和0.6783。初次性成熟最小叉长为106mm,生殖期1-9月,盛期为6—9月。食料以底栖生物为主,兼食浮游生物和游泳生物,平均摄食等级1.64。最适捕捞叉长和体重分别为128.7mm和38.4g。最佳最小可捕叉长及体重分别为104mm和21.6g。更多还原

【Abstract】 Totsl 1175 specimens of Upeneus bensasi caught by single boattrawling in Minnan - Taiwan Bank Fishing Ground were collected from July, 1992 to June, 1993. The range of their fork length composition is 55 to 180mm, and dominant groups are 1000to 130mm. Age group I is dominant in the catch. The range of their body weight composition is 4 to 114g ,and dominant groups are 10 to 40g. The parameters of growth equation of von Bertalanffy are :L = 201. 91mm, W= 211. 71g,K = 0. 2010,to =-3. 2414. opulation survial and annual mortality rates are 0. 3630 and 0. 6370,the instantaneous of total mortality,instantaneous natural and fishing mortality rates are 1. 0134,0. 3351 and 0. 6783 respectively. The spawning period is from Jan. tk Sep. The optimum fishing rork length and pody weight are 128. 7mm and 38. 4g respectively, The best minimum of fishing fork length and body weight are 104mm and 21. 6g respective-ly.更多还原
