Method for culturing two batches of ietalurus punetaus in one year

Abstract

The invention discloses a method for culturing two batches of ietalurus punetaus in one year. The method comprises the following steps of: A, building a culture pond: designing the specification of the culture pond, and equipping required equipment; B, performing disinfection of the culture pond: disinfecting the culture pond and a water body before fries are put into the pond; and C, culturing the water body: performing nutrient and water culture bait by using a water body culture agent A and a bait source culture agent B, wherein the water body culture agent A is prepared by fermenting soybean meal, wheat bran, corn flour, fish meal, cane molasses and the like through saccharomycetes, lactobacillus acidophilus and a compound enzyme preparation; the compound enzyme preparation is one or amixture of protease, cellulase, amylase and pectinase; the bait source culture agent B is prepared by premixing algae, such as diatom and chlorella, biological enzymes and minerals; and the mineralsare one or a mixture of calcium, magnesium, phosphorus, iron and the like. Due to cooperation of the water body culture agent A and the bait source culture agent B, the water body can be purified; intestinal absorption of ietalurus punetaus is improved; and the culture period is shortened.

Description

technical field [0001] The invention relates to the technical field of aquaculture technology, in particular to a method for cultivating two batches of channel catfish a year. Background technique [0002] Channel catfish (Ietalurus punetaus) belongs to Siluriformes and Catfish family. It is native to the Americas. It has the characteristics of fast growth, wide temperature range, and strong disease resistance. Its meat is delicious and has high nutritional value. It can be marketed all year round. It is deeply loved by farmers, processing plants and consumers at home and abroad, and has broad prospects for breeding. [0003] However, at present, many farmers do not pay attention to the breeding environment of channel catfish, which leads to slow growth of channel catfish. At present, a channel catfish weighing 0.3 catties / tail needs to grow to 1.8-2.5 catties / tail, which takes 8-9 months. This is because farmers do not pay attention to the water environment and breeding met...
