摘要
研究了黄鳍鲷(Sparuslatus)池养生长特性和饲养技术。单养黄鳍鲷的旺生长期1+龄。应用vonBertalanffy方程,求得人工饲养条件下其体长、体重生长方程为Lt=248.1759[1-e-1.0314(t+0.1483)];Wt=469.2926[1-e-1.0314(t+0.1483)]2.8302。体重生长拐点于0.86龄处。进行288.2hm2的河口近岸池塘单养和混养,单养周年平均单产7.3t/hm2,以黄鳍鲷为主养的混养,平均单产8.25t/hm2。起产最佳规格200g/尾。投入产出比1:1.33。
In this paper growth characteristics of pond-reared Sparus latus and its rearing technique were studied. The peak of growth period of monoculture Sparus latus was atthe age of one-year. According to von Bertalanffy equation, the growth equations for itslength and weight under the artificial culture condition could be experssed as Lt=248.1759[1-e-1.0314(t+0.1483)]and Wt=469.2926 [1 - e-1.0314(t+0.1483) ]2. 8302 respectively. The growthinflection points of body weight is at tr=0. 86. The area of rearing ponds about 400hm2 islocated on the river mouth and coastal beach. The yearly average output of its monoculturewas 7. 3t/hm2, as to the polyculture, major culture with S. latus, its average output was8. 25t/hm2. The optimum catchable size of the fish was 200g, and the ratio of input tooutput was 1: 1.33.
