为了发展沿海干旱地区的水产养殖,科威特对斯匹勒斯罗非鱼(Oreochromis spilurus)海水养殖的产量与投饵量进行了研究。根据生长率与饵料转换率的结果,体重70~130克鱼的最适日投饵量为鱼体重的2%;250~400克鱼的最适日投饵量为1.5%。海水水道养殖的罗非鱼在124天内从142克长至290.1克,每尾鱼的日生长率为1.19克/天,产量35.2公斤/米~3;海水网箱养殖的罗非鱼在101天内从118克长至323.3克,每尾鱼的日生长率为2.03克/天,产量44公斤/米~3;海水槽养殖的罗非鱼在180天内,从23.1克长至259克,每尾鱼的日生长率为1.28克/天,产量36.4公斤/米~3。这些结果表明,商业性海水养殖斯匹勒斯罗非鱼大有前途。
In order to develop aquaculture in dry coastal areas, Kuwait conducted a study on the yield and the amount of mariculture of Oreochromis spilurus. According to the results of growth rate and feed conversion rate, the optimal daily feeding amount of fish with body weight of 70-130 grams is 2% of the body weight of fish; and the optimum daily feeding amount of fish with 250-400 grams is 1.5%. Tilapia cultured in seawater grew from 142 to 290.1 grams in 124 days with a daily fish growth rate of 1.19 g / day and a yield of 35.2 kg / m 3; tilapia cultured in seawater cages were grown within 101 days From 118 grams to 323.3 grams, the daily fish growth rate was 2.03 g / day and the yield was 44 kg / m 3; tilapia cultured in seawater troughs grew from 23.1 grams to 259 grams in 180 days, with each tail Fish daily growth rate of 1.28 g / day, yield 36.4 kg / m ~ 3. These results indicate that commercial mariculture Spillers tilapia promising.
