Embodiment 1

[0017] A breeding method for improving the survival rate of fish, comprising the steps of:

[0018] 800 grass carp, 500 herring, 200 silver carp, and 200 male carp are raised in each pond. Before putting the fry into the fish pond, measure the water quality, temperature, and oxygen content of the fish pond to determine the environment of the fish pond After the fish are suitable for growth, use a small-caliber purse seine to isolate an area on the edge of the fish pond, and then put all the fry in the isolated area for breeding, and feed fish meal 95, silkworm chrysalis meal 75, corn meal 200, and cotton meal 80. , The proportion of potato protein powder 70% is formulated into feed, and it is fed once a day at 8:00, 1:00 and 6:00 respectively. After breeding in an isolated area for 15 days, remove the seine and feed once a day at 6:30, 10:30, 14:30, 19:30, the feed is 150 grass, 150 corn, 80 fish meal, 100 wheat, Cotton meal 80, vitamin A5, vitamin C5 ratio is formulated, the...

Embodiment 2

[0020] A breeding method for improving the survival rate of fish, comprising the steps of: breeding 900 grass carp, 500 herring, 300 silver carp, and 200 male fish in a pond per mu; The water quality, temperature, and oxygen content of the fish pond, after confirming that the environment of the fish pond is suitable for fish growth, use a small-diameter seine to isolate an area on the edge of the fish pond, and then put all the fry in the isolated area for breeding, and According to the ratio of fish meal 98, silkworm chrysalis meal 78, corn meal 210, cottonseed meal 85, potato protein meal 75, the feed is formulated, and fed once a day at 6:00, 12:00 and 18:00 respectively. It depends on the body weight of the fish, which is generally 3% of the body weight of the fish. After the fry have been cultured in the isolated area for 15 days, the seine net is removed and fed once a day at 6:30, 10:30, 14:30, and 19:30. , the feed is prepared according to the proportion of grass 160, ...

Abstract

The invention discloses a breeding method capable of increasing the survival rate of fishes. The breeding method comprises putting fries into a fishpond, measuring the water quality, the temperature and the oxygen content of the fishpond to guarantee the fishpond environment is adaptive to fish growth, then isolating an area nearby the fishpond edge by using an encircling net with a small mesh size, putting the fries into the isolation area according to a ratio of 1700-2300 fries in every mu of the fishpond, and feeding fodder to the fries at morning, noon and afternoon every day, wherein different kinds of fries can be put in the isolation area, and the fodder is pasty or granular, and is prepared according to the following ratio: 90-100 parts of fish meal, 60-90 parts of silkworm chrysalis powder, 150-200 parts of corn powder, 70-90 parts of cottonseed meal and 60-80 parts of tomato protein powder.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a culture method for improving the survival rate of fish. Background technique [0002] Due to the delicious meat and high nutritional value of fish, it is loved by people. However, in the process of fish farming, a large number of fish are often killed due to wrong farming methods, which reduces the income of farmers. Different farming methods raise The fish that come out not only have different growth rates, but also have different health levels. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a culture method for improving the survival rate of fish. The fish raised by the culture method not only have a high survival rate, but also have a fast growth rate. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a culture method for improving the survival...
