Problems solved by technology

Therefore, the microecological preparations, inorganic and organic agricultural miscellaneous fertilizers currently used for shrimp farming still have many shortcomings, such as unscientific formulas, unstable effects, and often too high usage in shrimp farming, which not only increases the cost of farming , and sometimes cause secondary pollution

Abstract

The invention discloses a microbial growth regulator for prawn culture and a preparation method thereof. The regulator is prepared from the following raw materials: prawn shell meal, soybean meal, peanut bran meal, cuttlefish paste (the water content is 30 to 50 percent), calcium dihydrogen phosphate, ferrous sulfate, copper glycine, zinc methionine, manganese glycine and papain with an activity unit of more than 0.5 million u. The regulator is formed by hydrolysis, polymerization and chelation reaction. The regulator contains the following active ingredients in percentage by weight: over 15 percent of protein, over 13 percent of total amino acid, over 0.83 percent of lysine, over 0.26 percent of methionine, over 2 percent of available phosphorus, over 2 percent of total calcium and over 1 percent of mineral element. The regulator used in a prawn culture water body can construct a complete food chain of the culture water body and effectively control the water quality of the water body; the regulator also can be used as a prawn feed additive and added in a low-temperature granulation process, and the regulator is an active ingredient of feed protein and is also prawn attractant; and the prepared feed used in the prawn culture has regulation effect on the water quality of the water body.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a microbial growth regulator for prawn farming and a preparation method thereof. Background technique [0002] In recent years, shrimp farming has developed rapidly in China. In 2007, the total output of shrimp farming in my country reached 1.26 million tons, accounting for about 37% of the world's total farming output. At present, my country has become the country with the largest shrimp output. With the expansion of the scale of prawn farming, the farming model is also constantly innovating, from extensive farming to semi-intensive, intensive, facility-based, factory-based, intensive farming models, or the coexistence of multiple farming models. Due to the pursuit of yield and economic benefits, high-yield and high-density farming has always been the mainstream. While this high-density culture mode greatly increases the production of prawns, the pollution to the culture wa...
