Why Does Shrimp Farming Lose Money? Real Case Analysis
In order to summarize the experience and lessons of crayfish farming, the author recently surveyed more than 20 shrimp farming ponds covering nearly 1,000 mu in the urban area. According to the survey statistics, in 2011, 80% of shrimp farmers made a profit, with an average profit of 750 yuan per mu, and the highest reaching 1,050 yuan. But nearly 20% of farmers suffered losses.

Detailed Explanation of Disease Prevention and Control Methods for Crayfish Farming
Because crayfish farming has only just started, and because disease occurs less under extensive farming conditions, the time devoted to researching crayfish diseases has also been relatively short. At present, many questions are still not fully understood, and viral diseases in particular still cannot be effectively treated. In dealing with shrimp diseases, one should base one's approach on

Procambarus clarkii, also known as red swamp crayfish, has strong adaptability, grows rapidly, has delicious meat, and is rich in nutrients. Market demand is strong, and it is highly favored by farmers and consumers. In production practice, Procambarus clarkii is mostly polycultured, such as in adult fish ponds, fingerling ponds, and river

Overwintering Management Experience for Broodstock Breeding Ponds in Crayfish Aquaculture
Throughout the entire overwintering period, broodstock basically do not feed and consume a great deal of energy. Therefore, before overwintering, feeding must be intensified to strengthen the broodstock's constitution, store the necessary nutrients for safe overwintering, and increase the overwintering survival rate. When the water temperature drops below 10°C, broodstock basically enter burrows to overwinter and rarely emerge to activity. At this time, the water level should be appropriately raised to ensure there is water or moisture in the burrows, but the water depth must not exceed the burrow entrance; it should be slightly lower than the entrance. Otherwise, the broodstock will emerge from the burrows and choose new places to dig. Once the broodstock have basically entered their burrows, spread a thin layer of plant straw along the water's edge around the pond perimeter, such as rice straw, reeds, cattails, etc. First, to keep warm; second, to provide a hiding and overwintering place for the juvenile crayfish produced before the broodstock overwinter.
