Intensified cultivation method of parent koi fishes

Abstract

The invention discloses an intensified cultivation method of parent koi fishes. The intensified cultivation method comprises the steps of 1, selection of a parent fish pool; 2, cleaning and water fertilizing for the pool; 3, selection of the parent fishes; 4, preparation before putting of the parent fishes into the pool; 5, intensified cultivation; 6, daily management; 7, gonad development and regulation. According to the intensified cultivation method, adopted pool cleaning chemicals contain natural ingredients, and the killing effect is significant; utilized organic fertilizer is simple in formula and easy to obtain, and rich plankton can be generated in the fish pool within a short term, and can serve as food for the parent koi fishes in the early stage and inhibit the reproduction and growth of harmful organisms. According to the method, by controlling the feed putting amount according to seasons, the types of the put feed and the content of nutritional ingredients of the put feed are adjusted at the same time, length and weight increase of the parent koi fishes can be sufficiently facilitated, and the stress resistance of the koi fishes is improved; by adjusting the water temperature and illumination intensity acceptable to fish bodies, the gonad development of the parent koi fishes and the stability of the water environment are promoted.

Description

technical field

[0001] The invention relates to the field of aquaculture, in particular to a method for intensively cultivating koi broodstock. Background technique
