Production practices have proved that the stocking of quality large-scale fish species can significantly increase economic efficiency. ?
First, grass carp reared 0.25 to 0.5 kg of fish species, when the end can be grown to 1.5 to 3 kg, 5 to 6 times the weight gain; rearing fish tail 0.1 to 0.15 kg of fingerlings, when the end of the year can grow to 1 to 1.5 Kilograms; Fish species 16.5 centimeters in length, can grow to more than 0.5 kilograms. ?
Second, flowers, white mullet rearing fish weighing 0.1 to 0.15 kilograms, when the end of the year can grow to 0.6 to 1 kilograms, about 7 times the weight gain; stocking body length of about 10 cm species, then only grow to 0.3 ~ 0.5 kg. ?
Third, the carp rearing 50 to 100 grams of fish species, to feed with the feed, the autumn harvest can grow to 0.8 to 1 kg. At the end of spring or early in the summer, thin-spotted Wuzi or indi- vidual-sized fingerlings are bred with high-quality squid compound feed, and most of them can grow to more than 0.5 kg in winter. ?
Fourth, carp rearing fish species weighing about 250 grams, when the winter catch can grow to 0.75 to 1 kg; stocking body length of 10 to 13 cm of fish species, the end of the year can grow to 0.25 kg or more. ?
Fifth, squid wild squid grows slowly and generally does not make relegation. The silver carp grows quickly and stocks fish weighing between 10 and 50 grams. It can grow to 0.3-0.4 kilograms during winter fishing. ?
Sixth, black wolfberry rearing 0.25 kilograms of fish species, to the end of the winter when the catch can grow to 0.8 to 1 kg; stocking body length of about 15 cm species, rearing to the end of the year can grow to more than 0.6 kg. ?
7. Tilapia In the middle of May, stocks of Nile tilapia 50 to 100 grams in tail weight can be raised to about 0.5 kg at the beginning of October. ?
8. In mid-May, freshwater white bream stocked with 0.25 kg of tailed fish can grow to more than 1 kg at the beginning of October; if it is stocked, then it can grow to more than 0.5 kg at the beginning of October.
