Artificial breeding method for bulgarus tinctorius

Abstract

The invention relates to the field of artificial breeding of fishes, and particularly discloses an artificial breeding method of Bulggalanga, which comprises the following steps: (1) selecting a fishpond: selecting a mud fishpond with the wall thickness of more than 30cm, and injecting clean running water into the fishpond; the water temperature of the fish pond is kept at 25-32 DEG C, 10000 fish fries are put per mu, and dissolved oxygen is kept above X; (3) feed feeding: feeding and domesticating the tinctoria ciliata fries so that the tinctoria ciliata fries are fed with floating feed, and feeding the tinctoria ciliata fries with specially-made feed at dusk every day, the specially-made feed containing 40% or more of crude protein; (4) net pulling for fishing: selecting net pulling for fishing in the morning or at night. According to the artificial breeding method of the dichocarchus bulbiferus, the growth of the dichocarchus bulbiferus is greatly accelerated through setting of a specific breeding environment, feeding domestication and special feed, and through the artificial breeding method of the dichocarchus bulbiferus, efficient breeding of the dichocarchus bulbiferus is achieved, the fry yield is increased, and the whole fish school breeding speed is increased.

Description

Technical field [0001] The present invention relates to the field of fish in artificial breeding, in particular to artificial breeding methods of Ding Galan. Background technique [0002] Ding Galan, famous Puntoplitesbui is a fish that is originally produced in major rivers in Malay Peninsula, and now also distributed in Sumatra, Borneo. Ding Galan often habitats in a wide range of water depths, belonging to the eating fish, with insects and water, with high economic value. Ding Galan fish can reach 50 cm, weighing up to 9 kg, which has been widely distributed in major rivers in Malay Peninsula. However, due to excessive capture, the wild Ding Galan is now relatively rare. Ding Galan is very similar to the South-Bangfish, but the color is less than the color of Ding Galan, the fins and fish of the fish, the meat is delicious, the fat content is high, suitable for a variety of cooking methods. [0003] Wild Ding Galan is high and rare. Since Ding Galan is a bottom fish, do not ea...

AI Technical Summary

Problems solved by technology

[0003]The price of wild Dingalan fish is high and rare, because Dingalan fish is a bottom fish, it does not eat floating water feed, and the water quality and temperature requirements are high, artificially large Large-scale breeding is difficult, and the growth of Dingalan fish is slow. Usually, it can only increase by 1 kg in 5 years, and generally more than 1.5 kg is economically beneficial, and the breeding cycle is long
