Problems solved by technology

Affected by natural conditions, especially the weather, the emergence season is late, which cannot meet the needs of the tilapia industry for a balanced product launch
Due to the obstacles in the traditional breeding technology, the seedling production season of this leading foreign exchange earning species is late, which affects the improvement of breeding benefits
Under natural conditions, tilapia starts to fry after April, and Hainan starts to raise seedlings from February to March. In order to save time, farmers hope to release seeds as early as possible in spring, which makes spring seedlings very tense and difficult to meet Demand, many farmers rush to buy seedlings from Hainan, the quality is uneven, which seriously affects the breeding effect

Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below.

[0034] This embodiment provides a rapid breeding method for tilapia early propagation, and the method is as follows:

[0035] The location is: Yingshan County, Huanggang City, Hubei Province. The pond size used is 1-3 mu, and the species used is Xinjifu. The ponds are heated by hot spring water and plastic greenhouses.

[0036] In the first ten days of January, the pond was cleaned with quicklime at a dosage of 75kg / mu. The whole pond was sprayed and the pond water retention was 0.3m. Parent stocking will start in mid-January. 1,800 fish (1200 female fish and 600 male fish) will be placed in a 2:1 ratio of male to female per mu. The method is to divide the hatching pond where the parents spawn into two halves, with 2.5cm mesh The upper side of the knotless mesh is 0.5m above the water surface, and the lower si...

Abstract

The invention discloses an early propagation and quick cultivation method of tilapia, and belongs to the technical field of tilapia culturing. According to the method, fry cultivation starts in the middle of January, and fries can be borne in early April; by means of strict fry cultivation condition control, the high survival rate and the high yield are guaranteed, the fry yield is 56-60 / kg, and fry bearing is very uniform.

Description

Technical field [0001] The invention belongs to the technical field of tilapia breeding, and particularly relates to a method for rapid breeding of tilapia early propagation. Background technique [0002] Tilapia is now a freshwater farmed fish cultivated by the key scientific research of the world aquaculture industry, and it is known as one of the main sources of animal protein in the future. It usually lives in fresh water, can also live in salt water with different salt content, and can also live in shallow waters of lakes, rivers, and ponds. It has strong adaptability, can reproduce in small waters, and can even grow in rice fields, and it has strong adaptability to water with less dissolved oxygen. The vast majority of tilapia is omnivorous, often eating water plants and debris. [0003] At present, the breeding of tilapia at home and abroad basically depends on the weather, that is, natural spawning and fry collection in broodstock ponds without control facilities. Affect...
