Abstract

The invention discloses a paddlefish breeding method, comprising the following steps of: (1) carrying out parent fish breeding and enriching breeding; (2) selecting parent fish; (3) carrying out artificial induced spawning; (4) carrying out artificial insemination; and (5) breeding by means of unsticking. By adopting the technical scheme, the paddlefish breeding method disclosed by the invention has the following advantages that 1. the whole flow of paddlefish from the parent fish breeding to fish fries breeding can be realized; and 2. the paddlefish is bred and bred by the above technology, so that the paddlefish breeding method is large in parent strain fecundity, good in maturity, high in induced spawning rate, and large in fish fry yield.

Description

technical field [0001] The present invention relates to a kind of spoon kissed sturgeon breeding method. Background technique [0002] Spoon-nose sturgeon ( Polyodon spathula ), belonging to the family Ployodontidae of the order Acipenseriformes, is widely distributed in large rivers in the central and northern regions of the United States and the nearby bay coasts, and occupies a very important position in the commercial and recreational fishing industries of the United States. In 1988, my country introduced the spoon-nose sturgeon from the United States for the first time. Because of its strong adaptability, fast growth and high economic value, it was quickly promoted to more than 20 provinces and cities across the country for breeding. Although my country achieved success in artificial breeding of the sturgeon in 2001, the development of the breeding industry of the sturgeon has been restricted due to the small number of parents, imperfect breeding technology, small bree...
