Embodiment

[0023] 1. Source and selection of broodstock

[0024] The mouse spotted in Taiwan, with a weight of about 1.5kg, was purchased in the natural waters. It was healthy, uninjured, with a complete body surface, bright color, obvious biological characteristics, and good vitality as the broodstock.

[0025] 2. Lectures and breeding of broodstock

[0026] In the sea area of ​​Hainan Lingshui Qingli Aquatic Products Company's fishing rafts, the wind and waves are small, the water quality is good, and the pollution is small. The annual water temperature is 14-30 ℃, and the salinity is 25-30. m. Feed fresh offal meat (fish with high protein and low fat is most suitable) every day, and the feeding amount is 5% of the body weight of all species. In addition, VitaminE (10mg / kg body weight, once a week) can be added to the bait. In order to improve the stamina and health of seed fish, vitamin C and B-complex (50mg / kg body weight, once every two weeks) were added.

Abstract

The invention discloses a small-water body fry rearing method for cromileptes altivelis. Fries suitable for selling and breeding can be reared by the steps of selection of a parent fish source, domestication and breeding of parent fishes, artificial maturation acceleration and spawning induction of the parent fishes, and the like. The method has the characteristics of low cost, high operability, higher fry rearing survival rate and stable production.

Description

technical field [0001] The invention relates to a technology for cultivating small water body seedlings of humpback perch, and belongs to the technical field of seedling breeding. Background technique [0002] Humpback bass, also known as Cromileptesaltivelis, is named for its long and pointed head and its shape resembling a mouse. Humpback perch is a high-grade seafood economical edible fish with high prices and is very popular among the masses. In recent years, the humpback bass sold on the market usually come from Southeast Asian countries. Although there are records of this species in the South China Sea, few of them are groupers with high economic value. Because of its fast growth rate and the ability to survive in confined waters, the humpback bass has great potential for breeding development. At present, most of the seedlings used for breeding humpback perch come from wild-caught fish fry in the sea, and the output of natural seedlings can no longer meet the market ...
