Crayfish get a claw in technology

He explains that excessively low density results in wasted feed and reduced yields. If the density is too high, crayfish will damage aquatic vegetation, degrade the pond environment, and suffer from stunted growth, ultimately producing small crayfish with poor meat quality.

"By selecting high-quality brood-stock crayfish and adopting scientific measures, we can achieve a self-sufficient supply of crayfish larvae," he says.

Li and his team are promoting technologies to help farmers supply their own crayfish larvae and raise crayfish year-round.

According to him, self-produced larvae are safer and more stable, can reduce farming costs, and can help control crayfish breeding.

In addition, Li says it is essential to provide nutritious feed for crayfish in winter to ensure they can molt and grow properly and maintain plump, firm flesh.

He explains that this is an eco-friendly farming model. Rice straw in paddy fields is turned into high-quality natural crayfish feed. In ponds, they plant suitable aquatic plants and regulate water quality to improve breeding and environmental conditions.
