Coastal Farmers Turn to Crab Fattening to Overcome Shrimp Losses

In the coastal regions of Satkhira and Khulna, livelihoods are deeply tied to aquaculture. For years, saltwater Bagda shrimp has been the primary cash crop. However, recurrent viral outbreaks have put shrimp farming at extreme risk. Once infected, an entire shrimp enclosure can die off within 10 to 15 days, leaving farmers in severe debt and unable to recover their investments.

To help farmers navigate this crisis, the voluntary organization Unnayan Prochesta, with financial support from the Palli Karma-Sahayak Foundation (PKSF), has introduced alternative livelihood initiatives. The organization is conducting training and field demonstrations on crab fattening for brackish-water farmers in Machiara village of Tala upazila and Kapilmuni in Paikgachha upazila.

Local fish farmers Mithun Mondal and Ripon Mondal are among the early adopters. “Unnayan Prochesta first provided us with a three-day training on crab farming,” they shared. “They then supplied us with improved crab fry, supplementary feed, bamboo netting (Bana) for fencing, and cash assistance. With their support, we successfully started crab fattening in our enclosures.”

Farmers report that both the market demand and the price for crabs remain strong. High-quality crabs currently sell for 1,000 to 1,200 Tk per kg. While prices fluctuate slightly, the financial risk is significantly lower than that of shrimp farming.

Saddam, a farmer from Kapilmuni, noted the financial relief the project has brought. “Recovering from shrimp losses was incredibly difficult for my family. This support has been a blessing. Experienced farmers know that with good seeds and proper management, it is possible to produce 25 to 30 kg of crab per decimal of land.”

S.M. Newaz Sharif Sumon, Fisheries Officer at Unnayan Prochesta, emphasized the importance of continued support. “Our responsibility doesn’t end with providing materials. We regularly supervise the farmers, train them on new technologies, and help them connect with local markets. Because crab fattening is profitable and takes less time, farmers are increasingly interested.”

Local government officials have also praised the initiative. Tariq Imam, Senior Fisheries Officer of Tala Upazila, and Saikat Mallick, Senior Fisheries Officer of Paikgachha Upazila, highlighted that the Bana method is quickly gaining popularity as a viable, low-risk alternative to shrimp farming.

“Climate change, diseases, and pests make single-crop farming highly risky,” said Sheikh Yakub Ali, Executive Director of Unnayan Prochesta. “Our goal is not just to implement a project, but to genuinely improve the farmers' quality of life by showing them resilient, alternative income paths.”

With lower feed costs, fewer diseases, and a quick 60 to 90-day harvest cycle, crab fattening is rapidly gaining traction as a lifeline for Bangladesh's coastal farmers.
