Cost of carp culture

The cost of one mu of carp culture is about 20,000 yuan, while that of parent fish is about 2 mu. Breeding parent fish should pay attention to the selection of good shape, strong vitality, no physical trauma, parent fish can lay eggs in March-August, but the number of eggs laid in April-June is the most exuberant.

1. The choice of pond

Generally, the price of one mu pond is about 600 yuan / year, and the area of farming depends on the specific situation.

2. Selection of fish fry

At present, the price of carp fry on the market is about 400 yuan / 10,000. If only 120000-150000 carp fry / mu are put in, the cost of carp fry is about 4800 to 6000 yuan.

3. Feed

The feed for cultured carp is indispensable, and it is the most expensive part for carp. In terms of one mu, the feed for fish fry is about 15000 yuan / year.

4. Fishery medicine

For breeding carp, the price of fish medicine is about 300 yuan a year.

5. Electricity charges

Generally, the electricity charge for raising one mu of carp is about 100 yuan / year.

Therefore, the cost of raising carp by breeders is about 20000 yuan per mu of pond.

How to cultivate high-yield carp

The main results are as follows: 1. in the process of carp culture, carp can mature at the second age, but some good individuals can also mature at the first age. Carp can spawn from March to August, but April to June is the most prosperous period for carp to lay eggs. Carp eggs are usually laid in shallow water, or in the grass in river bays. The number of eggs laid varies according to age and fish size, ranging from 15 to 800000 eggs. Fish eggs can hatch in about 5 days at a water temperature of about 20 ℃.

2. When culturing carp, the fry with good shape and strong vitality should be selected, and the fish with a ratio of body length to body height at 3:1 should be selected for culture. It is better for females to keep their body weight above 1.5kg at the age of 2 winters, and for males at the age of 2 winters and above 1kg. The first spawning and declining carp should not be selected as parent fish because of their poor spawning quality.

3. The pond for breeding parent fish is generally about 2 mu, and the water depth should be about 1.2m. Choose the place with good lighting and convenient water source, generally put 200kg per mu, and disinfect the pond with lime and bleach before stocking. In artificial reproduction, males and females are separated to prevent them from mating and spawning themselves.

4. The cultivation of parent fish can be fed with high-protein feed such as bean cake, silkworm pupa and fish meal, as well as parent fish feed, which is rich in ve and other vitamins, which can promote the development of parent fish and improve their anti-stress ability. In the process of feeding, we also need to pay attention to the regulation of water quality, maintain micro-running water, and regularly inject new water to stimulate the gonadal development of parent fish.

5. start eating young fish early and try to make the transition to full-price compound feed as soon as possible. The parent fish grows very fast in the prosperous eating period, the body length and weight increase very fast, and the more feed is needed, at this time, the feeding amount should be increased, and the feeding should be completed by quality, timing, positioning and quantity. So that the fish species can achieve a better fecundity.
