Embodiment

[0028] 1) Pond conditions: In March 2018, 3 new rectangular ponds were excavated in Suqian, Jiangsu, with sufficient water source, fresh and pollution-free, convenient inflow and drainage, and areas of 15×667㎡, 17×667㎡, and 20×667㎡. The loose soil is rich in humus, the silt depth is 0.1m, and the water retention is good; the surrounding ridges are 1.2m wide, and the ridges are 0.8m above the ground in the shallow water area;

[0029] 2) Excavation of the ring trench: the ring trench is excavated 0.5m away from the surrounding ridge, the bottom of the trench is 3.5m wide, 1.4m deep, and slope ratio 1:4.4. The area of ​​the 3 deep water areas at the entrance is approximately as attached figure 1 Shown

[0030] 3) Inlet and drainage facilities: leave a channel with a width of 3m at one corner of each pond, bury cement pipes with a diameter of 1m underneath, connect the ring trenches on both sides, so that the water body can circulate and rotate; equipped with 3 7.5kw pumps, drainage ...

Abstract

The invention discloses a breeding method for intercropping semen euryales with largemouth bass. The method comprises the following steps of 1, circular ditch excavation; 2, pond opening cleaning andpreparation; 3, fingerling stocking; 4, feed feeding; 5, semen euryales planting; 6, field management; 7, water quality management; 8, semen euryales picking; and 9, fish catching. According to the breeding method, the breeding mode of intercropping the largemouth bass in a semen euryales pond is adopted, the planting and breeding mode is novel, the yield, specification and quality of the semen euryales are not influenced, the water body space is fully developed and utilized, and the pond breeding variety is increased. The largemouth bass can eat small fishes, shrimps and insects, the diseaseoccurrence rate of the semen euryales is reduced, and the market risk caused by single semen euryales planting is effectively avoided; meanwhile, the semen euryales shades the largemouth bass, excrement is fully absorbed and utilized, water body pollution is reduced, the economic benefit is 16% or above higher than the economic benefit of single semen euryales planting, ecological environment protection is facilitated, and the method has important significance in promoting semen euryales planting and industrial development of the largemouth bass.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for breeding largemouth bass in gorgon interlocking. Background technique [0002] Largemouth Bass ( Micropterussalmoides ), also known as California perch and black perch, belonging to Perciforme, Ceutrarchidac, Micropterus, is a carnivorous warm-water fish, native to the Mississippi River in California, USA. The fish has excellent characteristics such as rich nutrition, delicious and tender meat, no intermuscular stab, beautiful appearance, fast growth, easy to catch, short breeding cycle, strong disease resistance, and wide temperature adaptability. It is very popular among farmers and consumers. It has been extended to all parts of the country and has become one of the important domestic freshwater aquaculture species. In 2018, the national output exceeded 450,000 tons, and the industry developed rapidly. However, the aquaculture mode is mainly high-density intensiv...
