How to polyculture mandarin fish for a high survival rate? Practical methods shared
Mandarin fish is a typical carnivorous fish that only eats live fish and live shrimp. Raising mandarin fish alone requires supporting the culture of forage fish, and the technical requirements are high. If mandarin fish are polycultured in adult fish ponds, the water body can be fully utilized and wild trash fish in the adult fish ponds can be cleared out. In recent years, some farmers have reported

Methods for Achieving High Yield in Intensive Culture of Yellow Catfish
1. Pond conditions: An intensive high-yield fish pond requires a good water source, convenient drainage and irrigation, an area of 1,334-3,335 sq m (2-5 mu), a water depth of 1.5-2 m, fresh water quality, abundant dissolved oxygen, and little sludge at the pond bottom. Still-water ponds must be equipped with aerators. Drain the pond water 7 days before stocking, and

Key Technical Points on Drug Use in Eel Farming in Summer and Autumn
In the high-temperature seasons of summer and autumn, eel growth is at its most vigorous, but the incidence of eel diseases is also at its highest. Many farmers, when eels fall ill, resort to desperate measures and use drugs haphazardly, only to spend a lot of money in vain without curing the eel diseases. Worse still, drug abuse causes water quality pollution,

How to raise river crabs for high yields? Farming experience shared
The pond area for river crabs is preferably 10-30 mu, with a pond depth of 1.2-1.5 m, a slope of 1:(2-3), and a surrounding trench around the pond 2 m wide and 1.8-2.0 m deep. The coverage area of aquatic plants should account for 40-60% of the pond area. Suitable aquatic plants include Elodea, Vallisneria, and Hydrilla.

Breeding experience for achieving multiple pregnancies and high productivity in guinea pigs
1. Timely mating. Because guinea pigs are small herbivorous mammals, their signs of estrus are not as obvious as those of other animals. If the methods used to observe estrus in other animals are applied to guinea pigs, it is easy to miss the mating period and cause losses to production. Therefore, it is necessary to observe
