Problems solved by technology

In order to speed up the growth of fish and gain weight quickly, farmers add various chemicals such as growth hormones, fattening agents, and antibiotics to the fish feed to speed up the growth of fish. Although these fish feeds can shorten the growth time of fish and increase weight quickly , but there are chemical drugs harmful to the human body left in the fish, which seriously endanger human health, and the meat of the fed fish is soft, with a strong fishy smell and poor taste

Embodiment 1

[0025] A kind of pollution-free fish feeding method specifically comprises the following steps:

[0026] (1) Pond construction and treatment: choose a place with abundant water sources and a cool area to build a pond with a depth of 1m. Before putting in fish fry, the pond is dredged and sun-dried. Regenerated lime and plant ash are prepared in a mass ratio of 1:1. 10% quicklime-plant ash solution, spray the whole pond and carry out disinfection treatment, standby;

[0027] (2) Cultivate plankton: 5 days before the fish fry are put into the pond, divide 200 kg of base fertilizer per mu into several parts and pile them up on the edge of the pond. Plankton The eggs or seedlings of jellyfish, rotifers, water fleas, tadpoles and mysis shrimp are used for plankton cultivation, and they are used for later use;

[0028] The base fertilizer is mainly retting from the following raw materials in parts by weight: 13 parts of high-calcium vegetable, 10 parts of green vegetable, 15 parts ...

Embodiment 2

[0036] A kind of pollution-free fish feeding method specifically comprises the following steps:

[0037] (1) Pond construction and treatment: choose a place with abundant water sources and a cool area to build a pond with a depth of 1.3m. Before putting in fish fry, the pond should be dredged and sun-dried. Be 15% quicklime-plant ash solution, spray the whole pond and carry out disinfection treatment, standby;

[0038] (2) Cultivate plankton: 6 days before the fish fry enter the pond, divide 300 kg per mu of base fertilizer into several parts and pile them up on the side of the pond, spread them evenly in the pond after retting and rot, pour into the pond water, and sprinkle them into the pond 1.5 days later. Plankton The eggs or seedlings of jellyfish, rotifers, water fleas, tadpoles and mysis shrimp are used for plankton cultivation, and they are used for later use;

[0039] The base fertilizer is mainly retting from the following raw materials in parts by weight: 14 parts ...

Embodiment 3

[0047] A kind of pollution-free fish feeding method specifically comprises the following steps:

[0048] (1) Pond construction and treatment: choose a place with abundant water sources and a cool area to build a pond with a depth of 1.5m. Before putting in fish fry, the pond should be dredged and sun-dried. Be 20% quicklime-plant ash solution, spray the whole pond and carry out disinfection treatment, standby;

[0049] (2) Cultivate plankton: 7 days before the fish fry enter the pond, divide 400 kg per mu of base fertilizer into several parts and pile them up on the side of the pond. Plankton The eggs or seedlings of jellyfish, rotifers, water fleas, tadpoles and mysis shrimp are used for plankton cultivation, and they are used for later use;

[0050] The base fertilizer is mainly retting from the following raw materials in parts by weight: 15 parts of high calcium vegetable, 15 parts of green vegetable, 17 parts of elongated grass, 5 parts of pine herb, 15 parts of royal gra...

Abstract

The invention relates to the technical field of aquatic product culture, in particular to a nuisanceless method of fish feeding. The method comprises the steps that 1, a pond is built, dredging and pond basking are conducted, and disinfection treatment is conducted with a quicklime-plant ash solution; 2, a base fertilizer is produced, and plankton is bred, wherein the base fertilizer is mainly obtained from retting sedum aizoon, phedimus aizoon, angelica keiskei, silphium perfoliatum, pnnisetumpurpureum pglaucum, clinacanthus nutans, berchemia lineata, amaranthus hypochondriacus, eragrostis tenella, maple leaves, picrasma quassioides leaves and a composite biological enzyme; 3, fry are released after being disinfected with a dithiocyano-methane potassium permanganate solution; 4, feeding and top dressing are conducted; 5, aquatic plants are planted to purify the water quality; 6, water quality management is conducted; 7, catching is conducted timely. By means of the method of fish feeding, most of feed of fishes is natural bait obtained from the pond, so that the feeding amount of the feed is reduced, the cost is lowered, use of chemicals is effectively reduced, and meat is firm, aromatic, delicious, rich in nutrients, safe and nuisanceless.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a pollution-free fish feeding method. Background technique [0002] Because of its delicious meat and rich polyunsaturated fatty acids, fish products have become a kind of meat product that is very beneficial to human health. Its consumption is increasing day by day and exceeds the growth rate of pork, beef and mutton, and it has become the main source of meat food. In order to speed up the growth of fish and gain weight quickly, farmers add various chemicals such as growth hormones, fattening agents, and antibiotics to the fish feed to speed up the growth of fish. Although these fish feeds can shorten the growth time of fish and increase weight quickly , but there are chemical drugs harmful to the human body left in the fish, which seriously endanger human health, and the meat of the fed fish is soft, with a strong fishy smell and poor taste.
