摘要
在常规土质鱼池中进行了吉富、“８８”、“７８”和埃及等四品系尼罗罗非鱼的起捕率比较试验。结果表明吉富品系的三网累计起捕率显著地高于其他品系（Ｐ＜０．０１）。１９９５年的试验中，吉富的三网累计起捕率为６７％，“８８”为３８％，“７８”为２３％，埃及为２２％。１９９６年的试验中，吉富的三网累计起捕率为８１．５％，“８８”为６２％。试验结果证明吉富品系尼罗罗非鱼的起捕率较高。
Experiments on catching rates of four strains of nile tilapia reared in earthen ponds were conducted in 1995 and in 1996 respectively. The accumulative catching rates were compared on basis of three trawls. Results showed that the catching rate of GIFT was significantly higher than those of the other strains ( P<0.01 ). In 1995, the catching rate of GIFT was 67%, while those of “88”, “78” and EGYPT were 38%, 23% and 22% respectively. In 1996, the catching rate of GIFT was 81.5% and that of “88” was 62%. Experimental results proved that GIFT was a strain of nile tilapia with a higher catching rate.
