Artificial culture method for diodon holocanthus fry

Abstract

The invention discloses an artificial culture method for diodon holocanthus fry. The artificial culture method includes the steps of culture pond preparation, fry screening, acclimatization and laterculture, wherein on the fourth to twenty-third day, the fry are fed and acclimatized according to the standard that the feeding amount is 3% of the total weight of juvenile fish, and sewage suction isperformed every day. The fry are fed with 80% of fortified big artemia salina, 19% of shrimp meat paste and 1% of vitamin C on the fourth to sixth day, the fry are fed with 50% of fortified big artemia salina, 49% of shrimp meat paste and 1% of vitamin C on the seventh to ninth day, the fry are fed with 20% of big artemia salina, 60% shrimp meat paste and 20% of fish pellet feed on the tenth to twelfth day, the fry are fed with 60% of shrimp meat paste and 40% of fish pellet feed on the thirtieth to fifteenth day, the fry are fed with 40% of shrimp meat paste and 60% of fish pellet feed on the sixteenth to nineteenth day, and the fry are fed with 20% of shrimp meat paste and 80% of fish pellet feed on the twentieth to twenty-third day; after the twenty-fourth day, the fry are directly artificially cultured and are fed full. The artificial culture method fills up the blank of a domestic artificial culture technology for diodon holocanthus fry.

Description

technical field [0001] The invention relates to a method for artificially cultivating spinyfish, in particular to a technique for artificially cultivating seedlings of spinyfish, and relates to the technical field of aquaculture. Background technique [0002] Diodonholocanthus (Diodonholocanthus) is a species of ray-finned fishes, Pufferiformes, Diodontidae. It is a tropical marine bottom fish, mainly inhabiting shallow reef areas, soft bottom seas or open waters. The meat of the six-spotted puffer is delicious, and the skin is rich in collagen, which is very popular in the market. At present, the source of the six-spotted puffer is all caught at sea, and the amount of resources is declining sharply due to overfishing by fishermen. Due to the unstable number of resource populations and obvious seasonal catches, the total catch output is not high, and the market is in short supply. Now its artificial breeding technology has been successful, but the cultivation technology of l...

Problems solved by technology

Due to the unstable number of resource populations of the six-spotted puffer fish, which have obvious seasonal catches, the total catch output is not high, and the market is in short supply. Now its artificial breeding technology has been successful, but the cultivation technology of later seedlings is currently still blank
