Problems solved by technology

[0003] At present, the main breeding methods of largemouth bass and Litopenaeus vannamei are still in monoculture and intensive culture. This long-term single culture mode often causes problems such as aging ponds, deterioration of water ecological environment, and increase in feed coefficient. Furthermore, diseases increased during the breeding process, and the production and benefits of farming decreased, which seriously restricted the rapid development of the largemouth bass and Litopenaeus vannamei industries
So far there is no report on the rotation of largemouth bass and Litopenaeus vannamei in ponds

[0026] 1. Pond selection: select the pond area to be 10×667m 2 The earthen pond has a flat bottom, the thickness of the bottom silt is less than 10cm, and the depth of the pond is 2.5m. The water inlet is filtered with a double-layer 80-mesh mesh; equipped with 5 sets of 1.5 kW aerators and 1 set of 2.0 kW microporous aeration equipment, the water quality is fresh No pollution. At the beginning of January 2017, 120kg / 667m was used after the pool water was drained and exposed to the sun for 10 days 2 Disinfect the clear pond with quicklime, add 0.8m of new water after 7 days, and prepare for the seedlings to be stocked.

[0027] 2. Largemouth bass farming:

[0028] (1) Seed release: On January 19, 2017, 50,000 off-season largemouth bass species that can eat artificial compound feeds were released, with a size of 8 cm / tail, soaked in 3% salt water for 5 minutes before releasing the seedlings, and used after entering the pond Povidone-iodine splashed the whole pool for disinfe...

[0038] 1. Pond selection: select a pond with an area of ​​15×667m 2 The earthen pond has a flat bottom, the thickness of the bottom silt is less than 10cm, and the depth of the pond is 3.0m. The water inlet is filtered by a double-layer 80-mesh mesh; equipped with 8 sets of 1.5 kW aerators and 2 sets of 2.0 kW microporous aeration equipment, the water quality is fresh No pollution. In early January 2018, use 120kg / 667m after the pool water was drained and exposed to the sun for 10 days 2 Disinfect the clear pond with quicklime, add 0.8m of new water after 7 days, and prepare for the seedlings to be stocked.

[0039] 2. Largemouth bass farming:

[0040] (1) Seed release: On January 18, 2018, 67,500 off-season largemouth bass species that can eat artificial compound feed were released, with a size of 10cm / tail. Before releasing the seedlings, soak them in 3% salt water for 10 minutes and use them after entering the pond. Povidone-iodine splashed the whole pool for disinfectio...

Embodiment 3

[0050] 1. Pond selection: select the pond area to be 30×667m 2 The earthen pond has a flat bottom, the thickness of the bottom silt is less than 10cm, and the depth of the pond is 3.2m. The water inlet is filtered by a double-layer 80-mesh mesh; equipped with 15 sets of 1.5 kW aerators and 3 sets of 2.0 kW microporous aeration equipment, the water quality is fresh No pollution. In late December 2018, use 120kg / 667m after the pool water was drained and exposed to the sun for 10 days 2 Disinfect the clear pond with quicklime, add 0.8m of new water after 7 days, and prepare for the seedlings to be stocked.

[0051] 2. Largemouth bass farming:

[0052] (1) Seed release: On December 28, 2018, 120,000 off-season largemouth bass species that can eat artificial compound feeds were released, with a size of 8.5cm / tail. Use povidone-iodine to splash the whole pool for disinfection.

[0053] (2) Feed feeding: On the second day after the largemouth bass went to the pond, they began to ...

Abstract

The invention provides an out-of-season alternate culture method for largemouth basses and litopenaeus vannamei in a pond. The method comprises the following steps that before and after January everyyear, out-of-season largemouth bass fries capable of eating artificial compound feed are put, and the largemouth basses are caught for sale when the largemouth bass fries are cultured to August; afterthe largemouth basses are sold in September, the pond is cleared, the litopenaeus vannamei are put and cultured, and the litopenaeus vannamei are cultured before and after January of the next year for fishing and selling; in the breeding process, aeration is conducted through micropores and a waterwheel aerator, and meanwhile a composite microecological preparation is splashed regularly to adjustthe water quality; and in this way, the largemouth basses and the litopenaeus vannamei are circularly and alternately cultured in sequence. According to the method, antagonism of alternate culture organisms and price advantages of out-of-season commercial fishes and shrimps are fully utilized, utilization efficiency of culture water space and time is improved, diseases are reduced, culture benefits are increased, and culture risks are eliminated.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a high-efficiency rotation culture technology for two kinds of aquatic products in ponds, in particular to a method for off-season rotation culture of largemouth bass and Litopenaeus vannamei in ponds. Background technique [0002] largemouth bass ( Micropterus salmoides ) belongs to Perciformes (Perciformes), sunfish family (Centrarchide), black bass (Micropterus), also known as California perch and largemouth bass, is a typical carnivorous wide-temperature freshwater fish, native to North America, last century It was introduced into my country in the 1980s and started breeding. Because of its advantages such as strong adaptability, fast growth, easy catch, and short breeding cycle, it has become an important characteristic freshwater aquaculture species in my country; at the same time, its meat is delicious and tender, without intermuscular thorns, and its appearance is beautiful, and ...
