Some skills of culturing crucian carp in ponds

When it comes to crucian carp, I think everyone is very familiar with it. In life, everyone should eat crucian carp. Crucian carp has high nutritional value, especially for some children to eat crucian carp is very effective in tonifying the brain.

Some skills of culturing crucian carp in ponds

1. Stocking density: crucian carp fry are cultivated in ponds, 8000-12000 crucian carp summer flowers are released per mu, and fish species with specifications of 50-60 grams can be cultivated. Crucian carp adult fish culture is carried out in the pond, with 1500-1800 crucian carp species per mu, with an average specification of 50-60g / tail, which can be cultivated into adult fish of 350g-400g.

2. Variety collocation: the number of silver carp and bighead carp should account for about 10% of the number of cultured crucian carp. Early release of silver carp and bighead carp will affect the domestication of crucian carp, and the best release time should be after the formation of the floating feeding habit of the main cultured crucian carp. Carp and grass carp float for a short time and grab food ferociously, which will not only affect the domestication of crucian carp, but also affect the annual feeding of crucian carp, so it is forbidden to match carp and grass carp in the main culture pond of crucian carp.

3. Domestication: adding an appropriate amount of food attractants (such as food-inducing peptides) to the feed can shorten the domestication time and increase the feeding area and quantity of crucian carp. The mackerel with the same caliber and feeding speed as crucian carp can improve the success rate of domestication and shorten the domestication time. Crucian carp is easy to be domesticated when the stocking density is high and the population is large. / 4, feed use: crucian carp seed material is used when the body weight is 50ml 100g, crucian carp small fish material is used when the body weight is 100ml 200g, and crucian carp adult feed is used when the body weight is more than 200g, which can not only maintain the normal body shape of crucian carp, but also reduce the feed coefficient and ensure the commercial specifications of adult fish.

2. Cleaning pond fertilizer and water: remove sundries and silt from the bottom of the pond. There are two methods: dry pond method and water-carrying method.

① dry pond method: use 60-75 kg quicklime per mu, keep 8-10 cm stagnant water in the pool, and mix the bottom silt and lime slurry evenly.

② with water method: water depth of about 50cm per mu, with quicklime 100kg-125kg, evenly sprinkle lime paste throughout the pond, generally 7-10 days after disinfection can release fish seeds. Water will be injected into the pond 5-6 days later, with a depth of 1.5-2.0 meters.
