Problems solved by technology

So far, the fish and shrimp polyculture method (Chinese patent CN200910041547.5) of existing tilapia and vannamei shrimp, but the stocking density of tilapia and vannamei shrimp is not high in this method, and the output is all low. The cost is relatively high, and the breeding benefits need to be further improved

Embodiment 1

[0025] In mid-February 2013, a pond with an area of ​​3.5 mu, a pond depth of 2.0 meters, unobstructed drainage channels, matching electrical equipment, complete oxygenation facilities, and convenient transportation was selected; the pond walls were cleaned and a small amount of silt could be left at the bottom of the pond; After drying the pond, thoroughly disinfect the bottom of the pond and the inlet and outlet pools; two 1.5kW impeller aerators are installed at the diagonal positions of the pond.

[0026] In the first ten days of March 2013, quicklime was used to disinfect the pond by dry method at a dosage of 100 kg / mu. After 6 days, the pond was filled with water. The depth of the pond was 2.0 meters, and the salinity was adjusted to 8‰. One week later, 35,000 Litopenaeus vannamei juveniles with an average body length of 2.0cm and healthy and non-disabled were put in; 18 days after the juvenile Litopenaeus vannamei was put in, gifu tilapia with an average body length of 4...

Embodiment 2

[0031] In the first ten days of March 2013, a pond with an area of ​​4 acres, a pond depth of 1.8 meters, unobstructed drainage channels, matching electrical equipment, complete oxygenation facilities, and convenient transportation was selected; the pond walls were cleaned and a small amount of silt could be left at the bottom of the pond; After drying the pond, thoroughly disinfect the bottom of the pond and the inlet and outlet pools; two 1.5kW impeller aerators are installed at the diagonal positions of the pond.

[0032] In late March 2013, quicklime was used to disinfect the pond by dry method at a dosage of 125 kg / mu. After 6 days, the pond was filled with water. The depth of the pond was 1.8 meters, and the salinity was adjusted to 8‰. One week later, 50,000 Litopenaeus vannamei juveniles with an average body length of 1.5 cm and no disease or disability were released; 20 days later, 22,000 Gifu tilapia with an average body length of 4.5 cm and no disease or disability w...

Embodiment 3

[0037] In mid-March 2012, a pond with an area of ​​5 mu, a pond depth of 1.6 meters, unobstructed drainage channels, matching electrical equipment, complete oxygenation facilities, and convenient transportation was selected; the pond walls were cleaned and a small amount of silt could be left at the bottom of the pond; After drying the pond, thoroughly disinfect the bottom of the pond and the inlet and outlet pools; install three 1.5kW impeller aerators at the diagonal positions of the pond.

[0038] In the first ten days of April 2012, quicklime was used to clean the pond by dry method at a dosage of 150 kg / mu. After 8 days, the pond was filled with water. The depth of the pond was 1.6 meters, and the salinity was adjusted to 8‰. One week later, 75,000 Litopenaeus vannamei juveniles with an average body length of 1.8 cm and no disease or disability were released; 15 days later, 35,000 Gifu tilapia with an average body length of 5 cm and no disease or disability were released. ...

Abstract

The invention provides a high yield and high efficiency breeding method for farmed tilapia and litopenaeus vannamei. The method comprises the steps: cleaning and disinfecting a litopenaeus vannamei breeding pond; putting 10000-15000 of the litopenaeus vannamei seedlings per acre, adjusting the salinity of water before putting to be 5%-8 %, and not feeding the litopenaeus vannamei artificial feed; 15-20 days later, putting 3500-6500 of the farmed tilapia seedlings; feeding with tilapia perfect compound feed, and controlling the water quality; capturing the litopenaeus vannamei after breeding for 2-3 months, capturing the big and leaving the small, drying the pond after breeding for 4-5 months, and capturing the farmed tilapia and the rest of the litopenaeus vannamei. By adopting the method, the out-of-pond specification, yield, the survival rate and the like of the farmed tilapia are better than that of a traditional single mode, the use area of the pond is reduced, diseases are reduced, the costs are reduced, and the out-of-pond specification and quality of the products are improved, the economic performance is increased, the yield and efficiency are improved, and a positive effect for stabilizing the enthusiasm of farmers is exerted.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a high-yield and high-efficiency culture method for Gifu tilapia and Litopenaeus vannamei. Background technique [0002] Tilapia (Tilapia) ranks third in the international trade of aquatic products and is one of the main farmed fish in my country. The current output has reached more than 1.4 million tons, accounting for about 34% of the world's total. It has become the largest fish in my country. variety of export aquatic products. Hainan Province is one of the earliest regions for tilapia farming in China. After years of development, it has become the main freshwater cultured species in Hainan. Since the 19th century, the tilapia industry in Hainan has been guided by the international market and led by processing, forming a considerable scale from seedling production, feed industry production, supply of fish supplies, commercial fish farming, fishing transportation, product processing...
