I. Pond culture
(A) The main pond culture ponds should not be small, generally 0.33-1 hectares per pond. The key paddlefish is the main fish, with grass carp, white pelicans, and gully. The stocking size of carp is 25 centimeters, 3000-3750 tails per hectare, 2250 tails per hectare of mixed fish, and the stocking specifications are smaller than those of squid. Stocking specifications. The husbandry and management methods are basically the same as those of A. cerevisiae, etc., and reference can be made to them.
(II) The requirements for ponds for ponds are the same as those mentioned above, but catfish are used for breeding. This type of farming is generally preferred for farmed fish, and of course it can also be used for breeding adult fish. Generally, 150-300 tail fish species with a stocking size of 15-20 cm per hectare are bred and the body weight can reach more than 1 kg after feeding for about 10 months.
Second, cage culture
The cage size is 5 meters 5 meters 2 meters, and each cage is stocked with 20-30 tails of 15 centimeters. Use artificial compound feed completely. Feeding 2 times a day, the daily feeding amount is about 2% of the fish's body weight, and the fish weight can reach 1 kilogram. Other feeding and management methods are the same as other fish in cage culture.
Third, lakes and reservoirs restocking
It is better to choose large- and medium-sized water bodies such as lakes and reservoirs with good water quality and abundant baits to stock eel, which will not only save feed costs but also grow quickly. In general, 150-225 tails of squid with a 15 centimeter stocking size per hectare do not need to be fed separately. When the end of the year, they can grow to more than 0.75 kg. If the waters are in good conditions, the food is rich, and when the end of the year the largest individual can grow to more than 1 kilogram. However, we must do a good job of preventing flight.
