A kind of method of cultivating the standard thickness of the same pond in high-level ponds of Penaeus japonicus family

Abstract

The invention provides a method for labeling and culturing a penaeus japonicus family in the same pond of a higher-place pond and relates to the cultivation of young shrimps. Sand is paved in the higher-place pond and the higher-place pond is disinfected; a pipeline device for inflating and oxygenating is mounted, and seawater is filtered by the paved sand; the whole pond is disinfected, and a nutrition preparation and a bacillus viable bacterium preparation are sprayed; a fixed suspension net box is produced; the young shrimps are selected and transported; after the young shrimps are put into the pond, the water level is raised; the bacillus viable bacterium preparation and an organic fertilizer are sprayed, and povidone iodine is sprayed to disinfect a water body; after the young shrimps are put into the pond, fairy shrimp larvae which are manually incubated are fed in the morning and at night of each day within first 10 days; during a cultivation post-period, a young shrimp particle feed added with vitamins, amino acids and a lactobacillus viable bacterium preparation is fed; during the cultivation post-period, a water sample is taken every 5 days to observe the quantity of vibrio; when a lot of the vibrio is bred, a disinfectant is used for disinfecting the higher-place pond and antibiotics are added into a bait; when the young shrimps grow to be about 4cm, a fluorescent mark is injected to carry out family marking, and all the marked families are put into the same higher-place pond to be poly-cultured, and then the same pond property testing experiment is carried out.

Description

technical field [0001] The invention relates to the cultivation of shrimp seedlings, in particular to a method for cultivating the Penaeus japonicus family in high-level ponds with the same standard thickness in the same pond. Background technique [0002] Compared with terrestrial animals such as pigs, cattle and sheep, which have a long history of economic breeding, the development and breeding history of aquatic animals is relatively short, especially marine aquatic animals. However, with the development of breeding theory and technology, especially the wide application of family breeding technology aimed at the characteristics of strong reproductive capacity and short generation replacement time of aquatic animals, a group of aquatic animals with excellent economic characteristics have also been successfully bred. Species such as Atlantic salmon, Nile tilapia and Litopenaeus vannamei (Gjedrem T. Genetic improvement for the development of efficient global aquaculture: a p...

Problems solved by technology

[0004] Malecha et al. used small suspended cages (0.1m×0.1m) on the indoor cement pool to standardize 50 families of Macrobrachium rosenbergii, but the total water body was small (1.5m 3 ), the aquaculture water body is difficult to maintain long-term stability (Malecha S R, Masuno S, Onizuka D. The feasibility of measuring the heritability of growth pattern variation in juvenile freshwater prawns, Macrobrachium rosenbergii (deMan) [J]. Aquaculture, 1984, 38 (4) :347-363) (The dissolved oxygen in the water body is too low during the roughing process, resulting in the death of a large number of larvae)

Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO) has used 34 indoor 0.1m 3 In the culture pond, the indoor standard of Penaeus japonicus family was carried out and the growth genetic parameters were evaluated. The results showed that the growth rate of the indoor cultured shrimp was slower, and the experiment did not set up parallel groups, so the environmental variance among the families could not be analyzed, which affected its genetic parameters. Accuracy of parameter evaluation (Hetzel D J S, Crocos P J, Davis G P, et al. Response to selection for growth in the Kuruma prawn, Penaeus japonicus[J].Aquaculture,1999,173(1-4):10)
