Embodiment 1

[0072] S1: Select healthy tilapia with a weight of 300g; the pond area used is 3 mu, the water depth is 1.5 meters; the stocking density is 3000 fish / mu; every 15,000 catties of fish is equipped with a feeding machine, and the number of feeding times per day is 2 times, each feeding time is 1 hour.

[0073] S2: The first stage: within the 1st to 9th day of feeding tilapia, the feed was gradually transitioned from ordinary tilapia feed to the first embrittled feed, specifically: the feed fed on the first day was changed from 10% The first embrittled feed and 90% of the common feed; the feed fed on the second day consisted of 20% of the first embrittled feed and 80% of the common feed; the feed fed on the third day consisted of 30% of the first brittle feed and 70% of common feed; by analogy, the feed fed on the 9th day was composed of 90% of the first brittle feed and 10% of common feed; all the first brittle feed was fed on the 10th to 29th day. chemical feed.

Embodiment 2

[0080] The present embodiment adopts the same materials and steps as in Embodiment 1, the only difference being: select healthy tilapia with a body weight of 400 g, and the stocking density is 2500 fish / mu.

Embodiment 3

[0082] The present embodiment adopts the same materials and steps as in Embodiment 1, the only difference being that healthy tilapia with a body weight of 500 g are selected, and the stocking density is 2000 fish / mu.

Abstract

The invention relates to a tilapia mossambica embrittlement breeding method which comprises the steps that tilapia mossambica with the body weight of 300-500 g is selected and bred for 2 months at the stocking density of 2000-3000 tilapia mossambica per mu, the weight of feed fed every day is 1.0-3.0% of the body weight of the tilapia mossambica, and the feed contains broad beans. By means of the tilapia mossambica embrittling breeding method, the quality of tilapia mossambica meat can be improved, and the tilapia mossambica meat is

Description

technical field [0001] The invention relates to the culture of tilapia, in particular to a culture method capable of embrittlement of the meat of the tilapia. Background technique [0002] Tilapia (Tilapia) is a tropical fish native to the Nile River Basin in Africa, belonging to the order Perciformes, the family Cichlidae, and the genus Tilapia. It has the characteristics of many varieties, fast growth, miscellaneous food habits, good meat quality and wide adaptability. It is the first aquatic product species promoted by the United Nations Food and Agriculture Organization (FAO) to the world in 1976 to solve the protein source of people in third world countries. Currently It has been popularized to more than 100 countries and regions for farming, and it is a veritable "world fish". [0003] China is the world's largest producer of tilapia, and tilapia is one of the most successful imported aquatic species in China. According to the 2021 China Fishery Statistical Yearbook,...
