Embodiment 1

[0024] Embodiment 1 provides a kind of California sea perch indoor factoryization full-season breeding method (in the present embodiment, the adjustment of following parameters within its scope has little impact on the survival of sea bass), comprising the steps:

[0025] (a) Parent introduction

[0026] At the beginning of March every year, when the water temperature is 15-17°C, the gonads develop to the fourth stage, the size is more than 1.3 catties / tail, and the ratio of male to female is about 1:1;

[0027] (b) Parental management

[0028] The temporary breeding density of the parent is 15-20kg per cubic water body; gradually adjust the temperature (when the parent is introduced, the temporary breeding water temperature is similar to the outdoor water temperature, adjusted to 15°C, and the temporary breeding is held for a week. When the loss of the parent is stable, gradually reduce the temporary breeding water temperature. , the temporary water temperature drops by 1°C ...

Abstract

The invention discloses an indoor industrial all-season breeding method for micropterus salmoides. The method includes steps: (a) parent introduction; (b) parent management; (c) parent breeding. The method has advantages that according to the development law of micropterus salmoides under unconventional conditions, by application of equipment facilities to totally-closed indoor industrial workshops, great development of parent gonads is realized from June to October, and suitable breeding conditions are created to realize all-season breeding method for micropterus salmoides, so that the problem of fry supply under market shortage conditions of marketable micropterus salmoides in high-temperature seasons is solved, and fish fry supply to a diversified multi-breeding mode of micropterus salmoides is realized.

Description

technical field [0001] The invention belongs to the technical field of fish fry breeding, and in particular relates to an indoor factory full-season breeding method for California perch. Background technique [0002] At present, the price of California perch commercial fish in Jiangsu, Zhejiang and Shanghai regions fluctuates greatly throughout the year, and the breeding benefits are unstable. Generally, the price is the highest in July to August every year, and starts to decline from October, and the price gradually recovers in May of the following year. The seed required for commercial fish farming in high temperature season has not yet been solved. Many farmers adopt high-density breeding in order to sell commercial fish at a good price, and press pond breeding until the high temperature season in July to August of the next year. This model has a long breeding cycle, high breeding risk and poor economic benefits, which is not conducive to the healthy development of Calif...
