在家鱼池塘中分别进行了套养丁鱼鱼种和商品鱼的试验。①鱼种混养 :在三个塘中分别进行丁鱼的鱼种单养、与白鲢鱼种混养和与草鱼鱼种混养 ,每个塘中平均每 6 6 7m2 放养的总鱼数为 3万尾。到年底时 ,三个塘中的收获结果如下 :成活率次序是草鱼塘 >白鲢塘 >单养塘 ( 90 .55% >88.1% >83.95% ) ;规格大小依次为草鱼塘 >白鲢塘 >单养塘 ( 41.8g>38.15g>32 .0 g)。②成鱼混养 :在白鲢主养塘和草鱼主养塘两种类型的池塘中平均每 6 6 7m2 放养 52 g左右的丁鱼 4 0 0尾 ,经 12个月的饲养 ,在上述两种类型的池塘中混养丁鱼的产量的高低次序依次是草鱼塘 >白鲢塘 ( 2 2 2 >198.3kg/亩 ) ;成活率次序为草鱼塘 >白鲢塘 ( 97.9% >95% ) ,平均规格大小的次序依次是草鱼塘 >白鲢塘 ( 0 .6 2kg>0 .599kg)。
In the home fish ponds have been planted with catfish species and commercial fish test. ① Mixed species of fish species: Monoculture of fingerling of Dingchu fish, polyculture with silver carp species and polyculture with grass carp finger fish were carried out in three ponds, and the average fish stocked in every 6 6 7m2 Number of 30,000. By the end of the year, the harvest results of the three ponds were as follows: the order of survival was that of grass carp pond> white carp pond> single-pond (90.55%> 88.1%> 83.95%); Silver carp pond> single pond (41.8g> 38.15g> 32 .0 g). ② Adult fish polyculture: An average of about 52 g of Dingyi fish was stocked at an average of 6 6 7 m 2 in two types of ponds, namely, silver carp main pond and grass carp main tangtang. After feeding for 12 months, The order of the yields of mixed catfish in the two types of ponds was grass carp pond> white carp pond (2222> 198.3 kg / mu); the survival rate was in the order of grass carp pond> white carp pond (97.9% > 95%). The order of the average size followed by grass carp pond> white silver carp pond (0.62kg> 0.599kg).
