| Abstract: | In 1995,1996 the net cages were set up in the ponds for intensive culture of adult fish to cultivate the commercial Xiang crucian carps and rear the fingerlings of the snakehead.Some technical measures were taken such as keeping the pond water slightly running with the method of drainage and irrigation,mechanical aeration,releasing the fishes able to endure the low oxygen,feeding with the animal meat and always clearing the net cages.The result showed that Xiang carps after cultivating 130 days increased the body weight from 150 g to 670 g,each day increasing 3.82 g on an average,and the output of the adult fish in a net cage with the area of 25 was 334.33 hg,average 13.37 kg/,survival rate 99.8%.The result also showed that the fingerlings of the snakehead were reared 42 days and their body length increased from 1 cm to 10 cm,each day increased 2.14 mm on an average,and th output of the fingerling in a net cage with the area of 20 was 552.4 kg(totalled 59480 ind.),13.81 kg/ on average,survival rate 74.4%.The result,appraised by expertsm,is worth spreading. |
