Tilapia culture method

Abstract

The invention provides a tilapia culture method. The method comprises the steps of throwing tilapia seedlings and conducting raising management on the tilapia seedlings, wherein the raising management comprises the steps that before the average weight of each tilapia reaches 200-245 g, granulated feed is used for feeding the tilapia, and after the average weight of each tilapia reaches 200-245 g, expanded feed is used for feeding the tilapia. By means of the tilapis culture method, the problems that in an existing tilapia culture method, rigid granulated feed or expanded feed is used in the whole course, the feed is wasted, the feed coefficient is high, and the water quality is polluted are solved; the problems that the fish irritability is poor, the tilapia is not resistant to long distance transportation, the tilapia is fat and has a big belly, the figure is poor, and the yield of mixed-culture variety is low are solved; by means of the tilapia culture method, the water quality can be adjusted easily, the efficiency of feed utilization can be increased, the yield of mixed-culture products can also be increased, and the purpose of culture benefit maximization is achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating tilapia. Background technique [0002] In aquaculture, feeding strategies play an important role in the artificial culture of fish. Improper feeding not only wastes bait and labor, but also pollutes water quality, causing bacteria and algae to multiply, and ultimately endangering the healthy and rapid growth of fish. Therefore, the feeding strategy has important economic and environmental significance for the sustainable development of aquaculture. Therefore, scientific feeding mode is particularly important for fish farming. Feeding rhythm is the biological basis for research and establishment of scientific feeding patterns. Due to different regions or different species, there must be some differences in the feeding rhythm of fish. Therefore, the feeding mode should be based on a deep understanding and research of fish activity laws, especially fe...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of culture method of tilapia, this method adopts the reasonable collocation feeding of hard pellet feed and extruded feed different from prior art in the culture process of tilapia, overcomes existing tilapia In the non-fish breeding method, feeding hard pellets or extruded feed throughout the whole process causes problems such as feed waste, high feed coefficient, and water pollution; Problems such as low yield of nested breeds; using this breeding method is easy to adjust water quality, can improve feed utilization rate, and can also increase the yield of nested products, so as to achieve the purpose of maximizing breeding benefits
