Problems solved by technology

[0003] At present, channel catfish and California perch are mostly cultured in monoculture or polyculture with seedlings at the same time. In the early stage of culture, the seedlings are small and the time is long. The water bod

Example Embodiment

[0010] Breeding pond selection:

[0011] The test site was located in Nanyu Village, Dangjiang Town, Beihai City. There are 2 breeding ponds, each of 7 mu, for experiment and control, and 1 standard thick pond, 1.5 mu. The ponds are all silt bottoms, the water source is taken from Nanliu River, the average water depth is 1.7 meters, and it is convenient to enter and drain.

[0012] Pond cleaning:

[0013] The pond should be trimmed before the rough and stocking, drain the pond water, remove the silt, and fully expose it to loosen the soil and decompose the organic matter; 20 days before the fish, add 40 cm of water, 70kg / mu of quicklime and disinfect the pond, 7 days before the fish Start to cultivate water and prepare to put fish.

[0014] Breeding management:

[0015] (1) Channel catfish breeding in one crop

[0016] At the beginning of September of that year, about 100g of fry were placed in the standard thick pond, totaling more than 17,500. At the same time, 300 silver carp large...

Abstract

The invention discloses an alternate culture method for ietalurus punetaus and micropterus salmoides. The method comprises the following steps: breeding ietalurus punetaus, namely breeding fries of ietalurus punetaus in a strengthening pond at the beginning of September in just the year, and 2 months later, transferring the fries of the etalurus punetaus into a breeding pond, starting grown fish breeding, wherein the breeding density is 2500 fishes/mu, and the grown fish breeding stage lasts for 12 months; harvesting the fish in October in a next year, and cleaning and sterilizing the breedingpond within October and November after harvesting in the next year; performing alternate culture on micropterus salmoides, namely breeding fries of micropterus salmoides in the strengthening pond within December in the year and January in a next year, in January of a next year, putting the micropterus salmoides into the pond of the ietalurus punetaus, starting grown fish breeding, wherein the breeding density is 1500 fishes/mu, and the breeding time is 7 months; and performing harvesting in August in the next year. By adopting the method, two kinds of fishes are bred at different stages, thegrowth peak periods of the ietalurus punetaus and the micropterus salmoides are staggered, then the micropterus salmoides can be prevented from massively predating the ietalurus punetaus at early breeding stages, the breeding load can be alleviated, the water body space utilization rate is remarkably and comprehensively increased, and the breeding risk can be reduced.

Description

technical field [0001] The invention relates to a rotation breeding method for channel catfish and California perch, belonging to the field of aquaculture. 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. Largemouth bass (Micropterus salmoides), commonly known as California bass and black bass, is also native to the Americas. It was introduced to my country in the early 1980s. It grows fast, adapts to a wide temperature range, and has relatively few diseases. Delicious and nutritious, easy to catch and other advantages, it has gradually become one of the main freshwater aquaculture ...
