Embodiment 1

[0030] A kind of cultivation method of selenium-enriched golden pomfret comprises the following steps:

[0031] S1. Disinfection: After treating the dry pond, sprinkle the above materials evenly on the bottom of the pond at the rate of 60kg of quicklime, 10kg of tea bran and 1kg of Bordeaux mixture per mu. After 7 days in the selenium pond, add water to the water depth of 10cm, and disinfect for 5 day; the water in the pond is pumped and drained, and the pH of the pond is repeatedly cleaned until it is about 7; 20 days before throwing seedlings, add water to 80cm in the pond, and throw tea seed cakes in the pond at a rate of 10kg / mu of pond to Kill wild fish eggs.

[0032] S2 Cultivation of water: drain the water in the pond, install a 40-mesh silk screen at the water inlet to prevent wild fish from entering, and add natural seawater or diluted seawater with a salinity of 12-20‰, and cast water per mu Apply 150kg of fermented organic fertilizer until the pool water is yellow-...

Embodiment 2

[0044] A kind of cultivation method of selenium-enriched golden pomfret comprises the following steps:

[0045] S1. Disinfection: After treating the dry pond, spread the above materials evenly on the bottom of the pond at the ratio of 70kg of quicklime, 5kg of tea bran and 0.8kg of Bordeaux mixture per mu. After 5 days in the selenium pond, add water to the water depth of 10cm, and then disinfect 7 days; drain the water in the pond, and wash it repeatedly until the pH of the pond is about 7; 20 days before throwing seedlings, add water to the pond to 70cm, and throw tea seed cakes in the pond at a rate of 8kg / mu. To kill wild fish eggs.

[0046] S2 Cultivation of water: drain the water in the pond, install a 40-mesh silk screen at the water inlet to prevent wild fish from entering, and add natural seawater or diluted seawater with a salinity of 12-20‰, and cast water per mu Apply 120kg of fermented organic fertilizer until the pool water is yellow-green or tea-brown.

Abstract

The invention provides a culture method of selenium-enriched Trachinotus ovatus, and belongs to the technical field of aquaculture. The culture method comprises the following steps of disinfection, water culture, seedling dropping and culture. Culture cost of the Trachinotus ovatus is high due to the fact that the Trachinotus ovatus is fierce, food intake is large, growth is fast and stocking density is low. According to the culture method, the Trachinotus ovatus and shrimps are mixed to culture, the polyculture shrimps eat feed residue of the Trachinotus ovatus, water pollution is reduced, resources are reasonably utilized, and the Trachinotus ovatus culture cost is reduced. In addition, the reasonable feeding mode is combined with selenium-enriched feed, selenium contents of the shrimps and Trachinotus ovatus are increased, and resistance and edibleness of the Trachinotus ovatus are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating selenium-enriched golden pompano. Background technique [0002] The scientific name of golden pomfret is egg-shaped pomfret, and the local names are yellow waxed pomfret and golden pomfret. Golden Pomfret contains a variety of nutrients. 100 grams of fish meat contains 15.6 grams of protein, 6.6 grams of fat, 0.2 grams of carbohydrates, 19 mg of calcium, 240 mg of phosphorus, and 0.3 mg of iron; it is rich in unsaturated fatty acids and has the effect of lowering cholesterol. [0003] The branch of the Hongshui River in Guangxi has a wide water surface and pure water quality, which is suitable for the development of cage fish farming. [0004] Pond cultured golden pomfret has fast growth rate, short cycle and low cost, so large-scale pond culture has developed rapidly in recent years. However, the stocking density of golden pomfret in ponds is low, ...
