Abstract

The invention discloses precision nutrient feed for tilapia at different culture stages based on solar term division and a feeding method of the precise nutrient feed. According to the growth and development characteristics of tilapia, based on the five solar terms of slight cold, rain, summer beginning, summer solstice and mid-autumn, the tilapia culture is divided into 5 stages, namely, an overwinter period, a recovery growth period, a fattening period, a high temperature disease period and a rapid growth period. At each culture stage, the nutritional level required for the growth and development of the tilapia is different, and accordingly, the feed nutrient level and the corresponding feed formula for different culture stages are designed. By use of the precise nutrient feed for the tilapia, the protein deposition rate can be effectively increased, the nitrogen emission can be reduced, the water quality can be guaranteed, diseases can be reduced, the yield can be increased, and thefeed formula cost can be decreased.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to precise nutritional feed for tilapia in different cultivation stages based on solar term division and a feeding method thereof. Background technique [0002] Tilapia farming means that the size of tilapia is raised from an average of 7 dynasties (about 1,000 fish / catties) to an average of 1.2 catties / tail for sale. [0003] At present, the protein content of tilapia feed is relatively high, and basically only one feed formula is used throughout the year, but the feeding rate is affected by the climate and there are large differences in different time periods. During the period of high feeding rate (such as July-October in South China), too much feed is put into the water, and fish take in too much protein, resulting in a decrease in feed protein deposition rate, excessive ammonia nitrogen discharge, and water quality deterioration, especially Moderate and high temperature ...
