Method of alternate culturing of South America white shrimps in yellow catfish aquaculture pond

Abstract

Provided is a method of alternate culturing of South America white shrimps in a yellow catfish aquaculture pond. The method comprises the steps of 1 offspring seeds purchase on selection and intermediate culture; 2 shrimp seed breeding in an earthen pond; 3 culturing management of the shrimp seeds; 4 the fishing of commercial shrimps for the market; 5 the preparation of the pond and the stocking of yellow catfish seeds; 6 the culturing management of the fish seeds is conducted; 7 the fishing of yellow catfishes. A specific culturing method is adopted in a series of the steps, so that the whole culturing period uses the water body space of the pond reasonably, the fishing carrying capacity is small in high temperature season, the biological prevention and control measure of aquatic product diseases are good, the occurrence rate of disease of aquatic products of scale is low, the efficiency of feed utilization is high, and the economic benefits and ecological benefits of the aquaculture pond are remarkable.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a high-efficiency ecological cultivation method for the rotation cultivation of Penaeus vannamei in a pond for cultivating pelagic catfish. Background technique [0002] In recent years, there have been many reports on the success of the monoculture and polyculture experiments of peltago grouse, but the aquaculture diseases such as "split head disease", hemorrhagic edema, spirosponge, and parasitic diseases It is also a trend of high incidence year by year, causing huge losses to farmers. In addition, the price of conventional fish has been sluggish for several years. Affected by this, the risk of adult yellow catfish farming has become prominent, and the confidence of farmers in farming has been seriously frustrated. The farming model and industrial structure of yellow catfish need to be adjusted urgently. [0003] Penaeus vannamei has the advantages of fast growth, low nut...
