摘要
研究金钱鱼Scatophagus argus的池养习性、食性和生长规律。金钱鱼为底栖动食性为主的杂食性鱼类,生长缓慢,始重0.06g饲养26月龄,日均增重(ADG)0.25g,月均增重率(GB_w)从341.67%,逐月下降至7.04%,月特定生长率(SGR_w)从102.92%逐月下降至6.58%。进行3.19hm^2池塘单养和混养,其中单养0.88hm^2,最高单产8823.5kg·hm^(-2),与多种河口近岸经济鱼类合理混养,间养最高单产占有量4716kg·hm^(-2),作为配养对象的混养,一般单产占有量183.4~576.6kg·hm^(-2)。金钱鱼是南海、东海南部沿岸地区海、咸水池塘极具开拓前景的饲养对象。
This article studied the pond rearing,feeding habits and growth law of Scatophagus argus. Scatophagus argus in an omnivorous but mainly carnivorous benthon,which grows slowly. Reared 26 months with the start weight of 0. 06g,the average daily growth rate of weight (ADG) is 0. 25g;the average monthly growth rate of weight(GRw) decreases from 341. 67% to 7. 04% ;the monthly special growth rate of weight (SGRw) decreases from 102. 92% to 6. 58%. Comparing monoculture with polyculture,the highest unit yield of monoculture is 8823. 5Kg·hm-2,and that of polyculture is 4716Kg·hm-2.The companion fishes' unit yield varies from 183. 4Kg·hm-2 to 576. 6Kg·hm-2. Scatophagus argus is a salty seawater rearing species with great prospects in the Nanhai Sea and south of the Donghai Sea
