Crab Farming Success Story
Success Story of Mr. Sharma
Mr. Sharma is a small-scale farmer from the region of Goa, India. He decided to venture into crab farming after researching the high demand for crabs in the local and international markets. He chose the mud crab species because of its fast growth, high survival, and high market demand. Mr. Sharma chose a 1-acre land near the coast with easy access to clean seawater for his crab farming project.
He built a pond with dimensions of 100 ft x 50 ft x 2 ft, which can hold up to 20,000 mud crabs. He installed a water pump and aeration system to maintain a constant seawater flow to the pond. He also constructed a shade to protect the crabs from direct sunlight and predators. Mr. Sharma bought 10,000 juvenile mud crabs from a reputable hatchery. He selected the healthy and active ones to ensure high survival rates.
The juvenile crabs were then acclimatized to the pond’s water parameters for two days before being released into the pond. After six months, the crabs were ready for harvest, weighing an average of 250-300 grams each. Mr. Sharma harvested the crabs using a crab net and sorted them according to size and weight. He sold the crabs to local seafood markets, restaurants, and exporters. The crabs fetched a good price of Rs. 1,000-1,200 per kg, giving Mr. Sharma a profit of Rs. 10-12 lakh per annum.
Management and Care
Mr. Sharma made sure to prepare the pond for the mud crabs properly. He removed any debris or obstacles from the pond, checked the water quality, and ensured the pond was deep enough for the mud crabs to thrive. Mr. Sharma was careful to select healthy juvenile crabs for his project. He ensured the crabs were disease-free and free from any deformities that could hinder their growth and survival.
Mr. Sharma provided his mud crabs with a balanced diet to ensure their health and growth. He provided a mix of natural feed like fish and prawns and supplemented them with formulated feed. He also monitored the feeding and adjusted the diet according to the growth rate of the crabs. Mr. Sharma ensured that the water in the pond was of the right quality and temperature. He regularly monitored the water pH, salinity, and temperature to ensure it was optimal for the mud crabs’ growth and survival.
Mr. Sharma proactively took measures to prevent and control diseases in his mud crab farming project. He used antibiotics and other medications judiciously when necessary and practiced biosecurity measures to prevent the introduction of diseases to the farm. He regularly monitored his mud crab farming project and took corrective measures whenever needed. He checked the pond’s water quality and temperature, monitored the crabs’ growth, and made sure that the equipment and infrastructure were working properly.
