Embodiment Construction

[0020] Preferred embodiments of the present invention will be described in detail below.

[0021] The embodiment of the present application provides a kind of domestication method of California perch specification fry (in the present embodiment, the adjustment of the following parameters within its scope has little impact on the survival of perch), at first according to the different stages of fish species, select different shapes and Fish species indoor ponds with an area (this application uses the following types: a circular pool with a diameter of 2.6m*height of 0.8m, a length of 4m*width of 4m*height of 1m, a length of 5m*width of 5m*height of 1m, a length of 6m*width 6m*1m high, 7.4m long*7.4m wide*1m high octagonal pool). The present invention selects a circular glass fiber reinforced plastic pool with a diameter of 2.6m and a height of 0.8m, drains 0.6m of water, and breeds 100,000 water flowers, with a density of about 50,000 fish / cubic meter and a water temperature of...

Abstract

The invention discloses a micropterus salmoides standard fry domestication method. The method includes that according to different fry stages, indoor fry ponds in different shapes and areas are selected, wherein the fry release density is 50,000-100,000 fry/cm<3>. A bait feeding method includes: (1) feeding with bait in four times each day; (2) gradually narrowing a feeding range; (3) starting feed domestication from the fifth day, wherein feeds including powder, a B2 material, a B3 material and an F3 material are added sequentially; (4) making the daily feeding quantity account for 10-30% ofthe fry weight; (5) screening. When a climatic environment is unsuitable, an indoor domestication technique is implemented, immunity of the fry is improved, activity is improved as well, and the fry survival rate is increased; by technical key point control of artificial culture of initial feed, artificial compound feed domestication and the like, micropterus salmoides standard fry culture techniques are integrated; by adoption of granulated feed for substituting iced fish in popularization and application to an aquaculture process, a consumption-reduction quality-improvement ecological aquaculture mode is shown, and win-win results of economic benefits and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of fish fry breeding, and in particular relates to a method for domesticating California perch seedlings. Background technique [0002] The California perch specification refers to the stage of growing from the water flower to a body length of more than 3 centimeters. The traditional method of raising seedlings is to spray water in ponds, feed on natural baits (rotifers, cladocerans, copepods), etc., and carry out chilling or feed domestication when they grow to 3 cm. The traditional breeding method is greatly affected by the weather, and the survival rate of the cultivation is unstable. When the climate environment is not suitable, the survival rate of the pond is low. Therefore, it is of great significance to carry out the research on the indoor domestication technology of California perch. Contents of the invention [0003] The present invention aims at the defects in the above-mentioned prior art, and...
