In recent years, as the area of crab farming has expanded, production has surged significantly. However, this growth has come at a cost—crab quality has declined, and shifting consumer demand in both domestic and international markets has led to falling prices. As a result, profitability has dropped, and some farmers have even suffered losses. In times of low prices, how can crab farmers still make a profit? The author believes that focusing on the following strategies can help improve efficiency and maintain competitiveness.
First, improving size and efficiency is crucial. Historically, large crabs have commanded higher prices than smaller ones, and they continue to be in high demand. Therefore, it's essential to shift from raising large numbers of small crabs to cultivating fewer but larger, high-quality crabs. By implementing practices such as "deep water, low density, and large individuals," farmers can ensure better growth conditions. This includes using high-quality feed that meets the nutritional needs of crabs, which helps produce large crabs with desirable features like a green shell, white belly, and golden claws—qualities that allow them to be sold at premium prices.
Second, focusing on quality and safety is key. Farmers should prioritize the source of their stock and establish a strong sense of safety awareness. This means maintaining and improving the breeding environment, creating pollution-free farms, and strictly following standards for seedlings, feed, medications, and storage. Promoting eco-friendly breeding methods, such as feeding live snails or small fish, can enhance product quality and win over discerning consumers.
Third, increasing efficiency through polyculture is another effective strategy. Certain carnivorous fish species, such as squid or snakehead, can coexist with crabs without conflict. These fish can consume leftover bait, reducing oxygen consumption and improving water quality, which in turn helps crabs grow faster and larger. For example, stocking 15–20 squid per acre of crab pond can yield 10–15 kg of marketable squid, adding approximately 300 yuan in extra income. Other suitable species include stingrays, prawns, and crawfish, allowing farmers to choose based on local conditions.
Fourth, disease prevention and cost reduction are essential for long-term success. By maintaining a clean ecological environment, farmers can strengthen the crabs’ natural resistance. Activities such as snail cultivation, water quality management, and proper feeding help reduce disease risks. Regular disinfection and minimizing the use of medication not only lower costs but also improve survival rates and overall productivity.
Finally, building a strong brand can significantly boost profitability. Consumers increasingly value branded crabs, and well-known brands like "Yangcheng Lake hairy crabs" often sell at much higher prices due to their reputation. Establishing a crab industry association, forming leading companies, and organizing farmers to collectively manage branding efforts can help maintain quality and meet market access requirements. Creating stable sales channels, such as specialized stores or trusted dealers, builds consumer trust and ensures long-term market presence.
