Problems solved by technology

Generally, the fish fry needed for barramundi farming are imported from Southeast Asia, but the purchased fish fry have the following problems in breeding: 1. The body length of the purchased fish fry is generally 8-10cm, and the individual is large, difficult to transport, and transported to death 2. The resistance of large-scale fry is reduced after long-term transportation, which directly affects the growth rate and survival rate of adult fish culture; 3. The adaptability of large-scale fry to different places is poor, which also directly affects the growth rate and survival rate of adult fish. Survival rate; 4. The cost of large-scale fry is relatively high, about 1.5-2.5 yuan per fish
Therefore, the existing imported barramundi fry have slow growth rate, low survival rate and high cost

Abstract

The present invention discloses the culture medicine of giant perch fry, and aims at provides culture medicine of giant perch fry with fast growth speed, high survival rate and low cost. The method includes desalted giant perch fry culture of fry in 10-25 days after hatching and fry length of 0.5-1.0 cm inside indoor culture pond with local culture salt content condition until fry length raised to 2.5-3.5 cm, and feed domestication in culture pond to fry length of 7-10 cm and to become fry with strong resistance and adaptability. The technology of the present invention is applicable in culture of other fish fry.

Description

technical field [0001] The invention relates to a method for cultivating fry, in particular to a method for cultivating barramundi fry. Background technique [0002] Barramundi (LATES CALCERIFER) is a marine fish with high nutritional value and economic value, and it is also an important cultured species in the estuary area of ​​southern my country.
