Mixed farming of turtles and earthworms in the same pond yields high economic returns
Under micro-flowing water conditions, amphibious turtles and aquatic earthworms are co-cultured in one pond, with the aquatic earthworms serving as the main feed or supplementary feed for the turtles. This can make the turtles strong and healthy, grow faster, shorten the breeding cycle, reduce feeding costs, and more than double economic returns. Moreover, throughout the entire rearing process, contamination of the product by hormone drugs is avoided, meeting the basic requirements for pollution-free food and making it more popular with consumers. The main technical points are introduced as follows: 1. Pond construction: choose a site with abundant water sources and good water quality

Juvenile and young turtles are also easily surrounded and

The snakehead (Channa argus) is the most widely distributed and highest-yielding species among the Channidae. As market demand grows, the snakehead may become one of the most promising aquaculture species in China in the early 21st century. China has a total of 7 species of Channidae, namely the snakehead (Channa argus), the spotted snakehead (Channa maculata), the dwarf snakehead (Channa asiatica), the broad-headed snakehead (Channa gachua), the striated snakehead (Channa striata), the slender snakehead (Channa limbata) and the elongated snakehead (Channa elongata). Among them, only the snakehead is a widespread species, distributed across all the major river systems of the country and also the highest in yield, while the spotted snakehead, the dwarf snakehead and the broad-headed snakehead are distributed only in South
