Salmon is a temperate freshwater fish native to Asia. Likes to live in the warm lake on the plain, or in the slow river. Belong to benthic omnivorous fish, meat and vegetarian food. The spectrum of baits is wide, the bones are well developed, and the mud is fed regularly. Squid is a low-temperature animal, the body temperature changes with the water temperature, no need to rely on energy consumption to maintain a constant body temperature, so the total amount of food required for bait is not large, the following will introduce the key steps in raising the yield of pond cultured carp.
Ponds fed with pellet feed to raise squid, can achieve high yield, high efficiency, 50 grams of squid species in spring, after 120 days to 150 days of feeding, up to 0.5 kg after autumn, the specific operation is as follows:
Pond conditions
The general requirements of the fish pond area should not be too large. The best is 5 mu to 10 mu, the water depth is about 2 meters, and the water source is convenient. Each acre of water is equipped with an aerator of 0.3 kilowatts to 0.5 kilowatts.
Fish species stocking
Restocking time
After the autumn of the first year or the spring of that year, the water temperature is 8°C to 10°C.
There are 800 to 1300 tails for the stocking species and the number of carp species, and 300 to 600 for the carp species.
Pond clearing and fertilization before planting
Lime dry clear pond, mu amount of 100 kg to 150 kg, Mushi base fertilizer (fermented chicken, cow dung as well) 150 kg to 400 kg, after the entire breeding process no longer fertilize.
feed
Raw materials and processing
During the feeding process, all the squid are fed with artificial compound feed, mainly local products such as cakes and bran, bran, etc., and appropriate amount of animal protein feed such as fish meal. The crude protein content is required to be around 30% to 35%, requiring basic amino acid balance.
Feed formula
A salmon feed formula is presented for reference: fish meal 5%, bean cake 10%, cotton kernel cake 20%, bran 35%, peanut cake 10%, cornmeal 5%, yeast powder 2%, minerals and multivitamins 2.5% , Salt 0.5%. This formula has a crude protein content of 30%.
Feeding management
Pay attention to the
Abnormalities were found and timely measures were taken to prevent flooding in hot and rainy weather. Appropriate amount of aerator, if necessary, infuse new water.
Feeding Technology
Each 5 mu ~ 10 mu set a one-spoke bait point: after the fish ponds combined with the sound training fish focused on rushing food, feeding adherence to four: timing, fixed-point, qualitative, quantitative. A small number of times, using artificial hand sprinkler or automatic feeding machine feeding, each feeding about 30 minutes.
Test
Test fish growth once a month and make a diary of the pond.
