Artificial cultivation method for culter alburnus

Abstract

The invention relates to the technical field of fry incubation and cultivation, and particularly relates to an artificial cultivation method for culter alburnus. The method comprises the following steps: (1) performing parent fish cultivation; (2) performing parent selection; (3) performing parent temporary cultivation; (4) performing artificial inducement for spawning; (5) performing fry incubation. By virtue of restricting a parent fish cultivation pool as a flowing water source which is nearly free from pollution, and replacing whole water in the pool every two days, the external environment for parent fish cultivation is clean and sanitary and is beneficial to healthy life and growth of parent fish; by virtue of replacing with fresh water every two days, the oxygen uptake function of the parent fish is relatively good; the internal water depth of the pool is 1.0 to 1.2m, the water surface area of each pool is 2.0 to 3.0mu, the internal water temperature of the pool is kept within a range of 24 to 25 DEG C, so that the flowability of water in the pool is relatively good, the water replacement capability is relatively good, the problem that the water replacement purpose cannot be realized due to relatively static water at the bottom of the pool is avoided by virtue of suitable depth, and too large water depth hardly enables the temperature of water at the bottom to be within the required range.

Description

technical field [0001] The invention relates to the technical field of fish breeding, in particular to an artificial breeding method for scalloped carp. Background technique [0002] Culter alburnus Basi lewsky, also known as Culter alburnus Basi lewsky (Latin scientific name), is large in size, slender, flat on the sides, in the shape of a willow leaf, with a straight back of the head and a raised back of the head, upper mouth and thick lower jaw Upturned sharply, standing in front of the mouth, making the mouth cleft vertical, big and round eyes, small scales, and the cocked mouth is a large-scale freshwater economic fish in the middle and upper layers. It moves swiftly and is good at jumping. [0003] At present, the market only relies on the naturally caught chrysalis, which cannot meet its demand, and the price remains high. Artificial breeding of chrysalis can obtain higher profits. Due to the increasing destruction of natural resources, the output of natural seedling...
