Problems solved by technology

In recent years, due to the use of plant protein and some low-value raw materials in the feed, the feed attraction and growth of some farmed fish have been greatly affected, resulting in reduced food intake, slow growth, and high mortality. This situation has seriously hindered the further development of the freshwater fish farming industry and the feed manufacturing industry.

Embodiment 1

[0016] A bream breeding method includes the following steps:

[0017] (1) Clean and disinfect the fish pond before stocking the fry;

[0018] (2) Fill the fish pond with water;

[0019] (3) After one week of water injection, the fry were stocked, bream was mixed with a small amount of crucian carp and grass carp. The polyculture ratio of bream, crucian carp and grass carp was 7:2:1;

[0020] (4) Stocking shrimps and snails in fish ponds;

[0021] (5) Feed the fish fry a mixed feed with a protein content of 35%;

[0022] (6) According to the water quality of the fish pond, use quicklime to control the water quality according to the amount of 20kg per mu;

[0023] (7) Regularly add fresh water to the fish pond to ensure the effective water level in the fish pond; the mixed feed is mixed with additives, which are prepared from the following raw materials by weight: 6 parts of Amomum villosum powder, 5 parts of tangerine peel, 6 parts of cinnamon Parts, peach blossom essential oil 3 parts, r...

[0034] A bream breeding method includes the following steps:

[0035] (1) Clean and disinfect the fish pond before stocking the fry;

[0036] (2) Fill the fish pond with water;

[0037] (3) After one week of water injection, the fry were stocked, bream was mixed with a small amount of crucian carp and grass carp, and the polyculture ratio of bream, crucian carp and grass carp was 8:3:1;

[0038] (4) Stocking shrimps and snails in fish ponds;

[0039] (5) Feed the fish fry a mixed feed with a protein content of 36%;

Abstract

The invention discloses a method for cultivating parabramis pekinensis. Additives in the compound feed have the effect of feed attracting and growth promoting; the source of the additive raw materialis stable, which can meet the olfactory and taste requirements of the parabramis pekinensis for the compound feed, and obviously accelerate the feeding speed and increase the food intake. The active ingredient and ratio of the feed additives are optimized by the inventors in the long-term experiment, and the feed attracting can be enhanced, and the anti-stress ability and growth rate of the parabramis pekinensis can be significantly improved, and the feed coefficient can be lowered. This feed additive is safe, efficient and has no toxic side effects for long-term use.

Description

Technical field [0001] The invention relates to a breeding method of bream. Background technique [0002] China is the world's largest aquaculture country and the only country in the world whose aquaculture output exceeds the catch output. The output of aquaculture products accounts for 70% of the world, and aquaculture occupies a very important position in the national economy. In recent years, my country’s aquaculture has developed rapidly, and freshwater aquaculture, as the most productive aquaculture model, has maintained an average annual growth rate of about 10%. In 2008, my country’s total production of freshwater products reached 22.973 million tons, of which freshwater aquaculture production was 20.725 million tons, accounting for 90% of my country’s total freshwater product production, while natural fishery production was only 2.248 million tons, accounting for about 10% (China Statistics Yearbook, 2009). Freshwater fish farming has a history of more than 3,000 years i...
