Silver carp growing flowers in 2000 mu reservoir

We are going to contract about 2000 mu of reservoir to raise silver carp in Anhui area. in order to maintain the quality of fish without feeding or fertilizing in the main culture areas, the water quality of the reservoir is very good and the water body is fertilized. put about 100 and a half jin of silver carp per mu with about 30 other fish, can it reach 4-5 jin after 3 years? is it appropriate to put in density? if there is a cage culture in the reservoir bay, what kind of species is better? how much is the specification density? Thank you renyonglin in 2009-10-9 17:18 to add the following content by the way to ask how much profit can be made each year after three years of farming, 2 million energy code-feeding process is recommended to use photosynthetic bacteria, Bacillus and EM bacteria and other microecological agents, with your planned breeding density three years income 2 million should be no problem. If the funds allow moderate cages to raise some yellow mulberry, beautiful frogs and other benefits are greater. -- Oh, learn like the landlord! -- Yes, the quality of the fish in the reservoir is good, but it can't sell at the same price. Thank you, brother on the first floor. Don't worry about the market. The average price of white fish is about 3.5 yuan. Renyonglin added the following at 09:49 on 2009-10-13. I put in seedlings every year. If I put in seedlings every year, what is the density in the first year? can they be released according to the above density? will they also release so much every year after that? can the annual income reach 2 million after three years of rotation? Thank you-only flower silver carp may not be so easy to do. 2 million is not so easy to get. It's still possible to put in 2 million fertilizer. Have you ever calculated how many jin of fish you need to get 2 million yuan per mu? Certainly carry on some other aquaculture in the reservoir bay renyonglin at 16:25 in 2009-10-13 supplement the following content less than three hundred jin of fish per mu ah-- do not feed? It doesn't grow fast-- silver carp is a freshwater filter-feeding fish. In the process of growth, it mainly feeds on plankton in the water. Silver carp feeds on phytoplankton, and silver carp feeds on zooplankton. For reservoirs without injecting fertilizer, it is necessary to fully consider the bearing capacity of the water body and match the proportion of flowers and silver carp. The imbalance will cause the body of water to be too thin and affect the growth rate of fish. It is suggested that feeding fish should be cultured in cages to increase the content of organic matter in water and maintain the stability of water quality. -I don't know what others contracted. My brother QQ403648714--, according to your stocking density, is a waste of resources. Are you talking about 2 million net profit? When you say water and fertilizer, it is now. How to maintain the fatness of the water body in the future?
