Bighead carp breeding technology

1. Scope

Suitable for silver carp and bighead carp pond farming.

2. Pond selection

The area of ​​the bighead carp fry breeding pond is 1/151/15hm2, the pond depth is about 1.5 meters, the pond embankment is firm and leak-proof, the pond bottom is flat, the amount of silt is appropriate, and there is no aquatic grass. The fish pond faces the sun and has sufficient sunlight. And it must be cleaned before stocking.

3. Water quality indicators

Implementation of "Fisheries Water Quality Standard" GB1607--1989 PH value 6.5---8.5 Dissolved oxygen ≥ 4mg/L Ammonia nitrogen <0.025mg/L Biochemical oxygen demand <5mg/L Others: Should comply with GB1607---1989 Fisheries Water Quality Standard 4) Feeding technology and feeding amount

4. Cultivation of broodstock

Before stocking broodstock, base fertilizer should be applied first. After stocking, topdressing should be applied according to the season and specific measures of the pond.

5. Feeding technique and amount of feeding

During the fish breeding period, artificial feed is used as a supplement. Before winter, about 1 kg of peanut bran or rice bran is added per 10,000 fish per day. After the weather turns cold, fertilization can be reduced, but the amount of peanut bran, rice bran, etc. added needs to be slightly increased to allow the fish to accumulate fat for the winter.

6. Use of fertilizer

The earliest fertilizers used in fisheries were primitive organic fertilizers, such as manure and compost, and later inorganic fertilizers, namely chemical fertilizers, were used. Although primitive organic fertilizers are nutritionally comprehensive, their effective ingredients are too low, and their fertilizer effect is slow, which limits fish production; although inorganic fertilizers have high effective ingredient content, their fertilizer effect is short, their ingredients are single, and they mainly cultivate small green algae and blue algae, which are beneficial to the growth of silver carp, but not ideal for bighead carp farming. Modern fishery bio-organic fertilizers, which are made by decomposing traditional organic fertilizers through modern biotechnology and mixing them with inorganic fertilizers in appropriate amounts, contain not only a large amount of nitrogen, phosphorus, carbon and other macroelements, but also balanced trace elements, a variety of organic matter, peptides, beneficial bacteria, fertilizer efficiency enhancers, etc., which are not only rich in nutrition and comprehensive, but also can fertilize, improve and control water, providing a good living environment for fish. Bio-organic fertilizers are particularly suitable for cultivating large algae, rotifers, cladocerans, copepods and other plankton that bighead carp like to eat, because they add a certain amount of organic matter, peptides and beneficial bacteria, and provide sufficient food for the high-yield farming of bighead carp.

6. Transportation Technology

1. Requirements: fresh water, high oxygen content, healthy fish, appropriate density and easy operation.

2. Mode: vehicles, ships, airplanes and other means of transport; containers include wooden barrels, canvas, nylon bags, etc.

Bighead carp is a filter-feeding fish. The general small-scale family farming model can fertilize the water to cultivate bait, ferment animal manure and then spray it throughout the pond, or dissolve chemical fertilizers in water and then spray it throughout the pond.

How many fingers of net does it take to catch a 13-jin silver carp?

Most fishing nets are used between two and three fingers, because this size can catch anything from one pound to thirteen pounds.

Thirteen pounds is too much for a quilt. It needs to be at least two meters by two and a half meters, which will be very thick.
