Problems solved by technology

The taste of tilapia fed with artificial concentrated feed is worse than that of naturally grown tilapia, the meat quality is loose, and the umami taste is reduced; while the growth cycle of tilapia fed with pure green feed is longer, which cannot meet the needs of the market
When tilapia is monocultured, there is a single species, the pond space and bait are not fully utilized, and the benefit is low. When polyculture, it is necessary to choose a reasonable species and quantity, which is in line with the ecological cycle of the pond

Embodiment 1

[0019] A tilapia ecological cultivation method is characterized in that, the stocking density of fry is 1800 / mu, wherein 90% of tilapia, the size of 100-200g / tail; 3% of crucian carp, of 50-100g / tail; 1% of grass carp , specification 20-50g / tail; catfish 2%, specification 100-200g / tail; bighead carp 3%, specification 100-150g / tail; perch 1%, specification 50-100g / tail; the weight ratio of feed is 10:3 Fermented feed and green fodder, the fermented feed is 120 parts of molasses, 90 parts of soybean meal powder, 25 parts of cottonseed protein powder, 12 parts of peanut meal, 12 parts of fish meal, 5 parts of bone meal, 0.2 part of sodium chloride, 0.15 part of calcium carbonate. It is fermented and decomposed by microbial inoculum. The components of microbial inoculum are yeast: lactic acid bacteria: Bacillus subtilis = 5:3:1. The green fodder is 45 parts of ryegrass, 15 parts of elephant grass, 3 parts of cucumber, sweet potato leaves 15 parts, 12 parts of radish leaves, and 5 ...

Embodiment 2

[0021] A tilapia ecological cultivation method is characterized in that the fish fry stocking density is 1600 / mu, of which 90% are tilapia, with a specification of 100-200g / tail; 3% of crucian carp, with a specification of 50-100g / tail; 2% of grass carp 1% catfish, 100-200g / tail; 3% bighead carp, 100-150g / tail; 1% perch, 50-100g / tail; the weight ratio of feed is 10:5 Fermented feed and green fodder, the fermented feed is 100 parts of molasses, 120 parts of soybean meal powder, 20 parts of cottonseed protein powder, 20 parts of peanut meal, 10 parts of fish meal, 8 parts of bone meal, 0.1 part of sodium chloride, 0.2 part of calcium carbonate. It is fermented and decomposed by microbial inoculum. The components of microbial inoculum are yeast: lactic acid bacteria: Bacillus subtilis = 5:3:1. The green fodder is 40 parts of ryegrass, 20 parts of elephant grass, 3 parts of cucumber, sweet potato leaves 30 parts, 5 parts of radish leaves, and 6 parts of sugarcane leaves are pulver...

Embodiment 3

[0023] A tilapia ecological cultivation method is characterized in that, the stocking density of fish fry is 2000 fish / mu, wherein 85% of tilapia, specification 100-200g / tail; 5% crucian carp, specification 50-100g / tail; grass carp 3% 20-50g / tail; 2% catfish, 100-200g / tail; 3% bighead carp, 100-150g / tail; 2% perch, 50-100g / tail; the weight ratio of feed is 10:2 The fermented feed and green fodder, the fermented feed is 150 parts of molasses, 80 parts of soybean meal powder, 30 parts of cottonseed protein powder, 10 parts of peanut meal, 15 parts of fish meal, 3 parts of bone meal, 0.3 part of sodium chloride, 0.05 part of calcium carbonate. It is fermented and decomposed by microbial inoculum. The components of microbial inoculum are yeast: lactic acid bacteria: Bacillus subtilis = 5:3:1. The green fodder is 50 parts of ryegrass, 15 parts of elephant grass, 5 parts of cucumber, and sweet potato leaves. 10 parts, 15 parts of radish leaves, 2 parts of sugarcane leaves are pulver...

Abstract

The invention provides a method ofecological tilapia breeding. According to the method of the ecological tilapia breeding, a bio-fermented feed and a grass feed are used. The water quality is regulated by the simulation of the ecologically poly-cultural system. The traditional Chinese medicine is used in the prevention and treatment of the fish disease. The chemicals are not added into the breeding process. The finished fish being fresh and smooth without the silt taste is the excellent aquatic product of the green pollution-free. The fermented feed, the green fodder and the Chinese herbal medicine are used with a wide range of the raw material and the low cost of the farming.

Description

technical field [0001] The invention relates to a freshwater fish culture technology, in particular to a tilapia ecological culture method. Background technique [0002] Tilapia has the characteristics of fast growth, miscellaneous food habits, few diseases, and strong adaptability. It has become one of the most widely farmed fishes in the world. Tilapia has a strong adaptability and is extremely adaptable to water with less dissolved oxygen. Tilapia meat is delicious, tender and contains a variety of unsaturated fatty acids and rich in protein. It has become the main farmed fish in the world and is very popular in the market. The taste of tilapia fed with artificial concentrated feed is worse than that of naturally grown tilapia, the meat quality is loose, and the umami taste is reduced; while the growth cycle of tilapia fed with pure green feed is longer, which cannot meet the market demand. When tilapia is monocultured, the species is single, the pond space and bait are...
