Problems solved by technology

[0002] Sea bass is a kind of nutrient-rich fish with high protein content, but the general sea bass has such disadvantages, that is, the general sea bass grows for a long time, and the survival rate of juvenile fish is low
In addition, the existing perch breeding methods are relatively complicated, especially the feeding of bait is inconvenient, and the dispersibility of the bait is poor when feeding, and the perch needs to be concentrated in a certain narrow area to eat, which is not good for feeding
Therefore, the existing perch farming methods need to be further improved

Abstract

The invention discloses a weever breeding method. The method includes following steps: (1), treating a pond: selecting a pond rich in water source, free of pollution, flat in bottom, with sandy mud atthe bottom and of 1.8-2.0m in depth as a breeding pond, draining water in the pond, using quicklime for disinfection according to 50-75kg / mu, and filling water to enable the depth of the pond to be 2-2.5m after 5-7d; (2), stocking fries: selecting weever fries of 4-6cm in length, and stocking 2500-3500 fries per mu; (3), feeding bait: adopting a feeding device to feed synthetic feed, wherein feeding amount of the synthetic feed accounts for 7-9% of total weight of fishes; (4), performing daily management: inspecting the pond every day, starting for oxygenation at night or in muggy weather orat low air pressure, and timely changing water to maintain the water in the pond to be fresh. The weever breeding method is convenient in breeding and high in weever survival rate and yield, and baitfeeding is high in dispersity and convenient for weevers to eat.

Description

technical field [0001] The invention relates to a perch breeding method. Background technique [0002] Sea bass is a kind of nutrient-rich fish with high protein content, but general sea bass has such disadvantages, that is, general sea bass grows for a long time, and the survival rate of juvenile fish is low. In addition, the existing perch breeding methods are relatively complicated, especially the feeding of bait is inconvenient, and the dispersibility of the bait is poor when feeding. The perch needs to be concentrated in a certain narrow area to eat, which is unfavorable for feeding. Therefore, the existing perch culture method needs to be improved further. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a perch breeding method which is convenient for breeding, has high survival rate of perch, high yield, good dispersion of bait feeding, and is convenient for perch to eat. [0004] The present inventi...
