Weever fry high survival rate seedling method

Abstract

The invention discloses a weever fry high survival rate seedling method; the specific method comprises the following steps: greenhouse culture pond preparation, fry inputting, bait feeding, fry irritability excises, outdoor seedling pond preparation and fry inputting, outdoor bait feeding, and water quality management. Compared with the prior art, the advantages are that the fry is cultured in the greenhouse in the early stage, the pond water is relatively shallow, the pond conditions are easy to control, thus reducing culture energy consumption under same conditions; the fry can fast grow in indoor culture, and multi-aspect anti-irritability excises are carried out before changing the pond, thus allowing the fry to have anti-irritability ability on light, temperature and water flow conditions; when the fry is transferred to the outdoor culture pond, the fry can fast adapt to the outdoor environment; corresponding protide fodders are added so as to improve fry ingestion and digest ability on the baits, thus improving fry survival rate and anti-disease ability.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a seedling raising method with high survival rate of perch fry. Background technique [0002] Perch belongs to Perciformes, Perch subfamily, euryhaline fish. It is distributed in the coastal areas of my country, rich in resources, and has the characteristics of fast growth, wide adaptability, strong disease resistance, and delicious meat. It is very popular among people. With the increase in demand, the culture ponds in the inland have gradually begun to breed seabass. However, due to immature nursery technology, it is usually necessary to purchase fish fry from coastal areas. The ability to adapt to different places is poor, and its disease resistance will also be greatly reduced, which in turn increases the cost of sea bass breeding. Contents of the invention [0003] The object of the present invention is to provide a kind of perch seedling raising method with...
