Abstract
The invention relates to a method for improving water quality of a fresh water culture pond and promoting fish growth, and aims to solve the problems of excess harmful nitrogen sources such as ammoniacal nitrogen and nitrous acid nitrogen, poor pond water quality and low survival rate of cultured fishes in the fresh water culture pond. The method comprises the following steps of: calculating amounts of cane molasses delta CH1, puffed corn delta CH2 and a salubrious element delta CH3 added into the fresh water culture pond each time according to the following formulas: delta CH1=65%*35*H*S*CNH3-N, delta CH2=30%*29*H*S*CNH3-N, and delta CH3=5%*20*H*S*CNH3-N; mixing the cane molasses, the puffed corn and the salubrious element; diluting the mixture; and uniformly spraying in the entire pond to finish the method. According to the method for improving the water quality of the fresh water culture pond and promoting the fish growth, the contents of the ammoniacal nitrogen and the nitrous acid nitrogen in the culture pond are reduced, the water quality of the pond is improved, and the growth rate and the survival rate of pond fishes are increased.
Description
Technical field
The present invention relates to a kind of method of improving the freshwater aquiculture pond water quality and promoting the fish bulk-growth.
Background technology
The freshwater output of breeding fish is increasingly high, because the feed of throwing something and feeding in a large number causes nitrogenous sources such as pond ammonia nitrogen, nitrite nitrogen to accumulate in a large number, causes water quality deterioration, has a strong impact on healthy fish and productivity.At present, most aquaculturists are generally through throwing in a certain in cultivating pool or several kinds of exogenous probioticses improve the pond water quality environment, yet effect is often also pessimistic, even growth that sometimes also can serious harm pond culture fish.In fact, no matter which kind of probiotics all is the bacterium that needs specific living environment, only could normal growth and breeding, its limited effect of competence exertion in the environment that can satisfy its physiological property demand.Any probiotics all can not be brought into play identical physiological function in the pond environment that environmental condition varies.
Carbon source is the necessary one type of nutrients of growth of microorganism.Pond interior carbon source shortage can cause the heterotrophic bacteria breeding to be obstructed.In whole breeding process; Usually exist serious imbalance between organic input of feed and the cultivating pool water body micro-ecological environment; Feed only considers to culture the nutritional need of object, does not consider the material balance of the whole pond waters ecosystem, especially carbon, nitrogen balance.As far as microorganism, nitrogenous sources such as the ammonia nitrogen in the cultivating pool water body, nitrite nitrogen are superfluous, the carbon source relative deficiency.And under normal conditions, inner its intrinsic microbiologic population that exists of cultivating pool.Therefore, utilize carbon, nitrogen balance principle to cultivate the endogenous microbes in the pond waters through in cultivating pool, adding carbon source, the method that is used for reducing harmful nitrogenous sources such as cultivating pool water body ammoniacal nitrogen, nitrite nitrogen is very useful.
Summary of the invention
The present invention will solve harmful nitrogenous source surplus such as ammoniacal nitrogen, nitrite nitrogen in the freshwater aquiculture pond, and pond water quality is poor, and the problem that the cultured fishes survival rate is low provides a kind of method of improving the freshwater aquiculture pond water quality and promoting the fish bulk-growth.
The present invention improves the freshwater aquiculture pond water quality and promotes the method for fish bulk-growth, carries out according to the following steps: one, calculate the amount of in the freshwater aquiculture pond, adding cane molasses each time by following formula: Δ CH
