Yes, mud crab farming is profitable if practised correctly and done with fewer mistakes. A detailed project report is shared here explaining mud crab farming profit and cost analysis.
Vertical crab farming occupies less space, has low cast and is a profitable business, especially in coastal areas; it can also be done in other regions by arranging ponds.
Vertical crab farming cost profit report
The vertical crab farming cost profit report is detailed in the project report below. The report is calculated for 2 years.
Project Report
- Crab cost per 0.1 hectare
- Crabs cost (soft) = Rs 25,000.
- Feed cost = Rs 8,000.
- Pond cost = Rs 25,000.
- Sluice gate price = Rs 25,000.
- Diesel pump price (set 5 hp) = Rs 20,000.
- Diesel pump price = Rs 1000.
- Bamboo fencing price = Rs 3500.
- Nylon net fencing price = Rs 2500.
- Casuarina poles cost = Rs 5000.
- Labour cost = Rs 10,000.
- Harvesting cost = Rs 8000.
- Miscellaneous cost = Rs 10,000.
- Total cost = Rs 143000
- Mud crab profit
- Crab price per kg = Rs 200.
- Crab production per 0.1 hectare = 320 kg.
- 1st year = 4 time harvesting.
- 1st year profit = 320 kg crab x 4 = 1280 kg crab.
- 1st year Profit = 1280 kg crab x Rs 200.
- 1st year profit = Rs 2,56,000.
- Net Profit = Cost (Rs 143000) – Profit (Rs 2,56,000)
- Net Profit = Rs 2,56,000 – Rs Rs 143000.
- Net Profit = Rs 113000.
- 2nd-year profit
- The crop is harvested 8 times in the 2nd year.
- 2nd year profit = 320 kg crab x 8 = 2560 kg crab.
- 2nd year Profit = 2560 kg crab x Rs 200.
- Net profit = Rs 5,12000.
- 1st and 2nd year profit = Rs 113000 + Rs 5,12,000 = Rs 6,25,000.
- Net Profit 2 years = Cost – Profit
- Net Profit = Rs 143000 – Rs 6,25,000 = Rs 482000.
- Net Profit = Rs 4,82,000.
Note – This is the crab farming project report assumption. The calculation for 2 years is done here. Prices may vary according to the price, market, variety and demand.
Cost – Vertical mud crab costing is around Rs 1,43,000. The costing contains pond construction, Sluice gate for water exchange, Diesel pump set 5 hp, Diesel for pumping, bamboo fencing, nylon net fencing, casuarina poles, labour cost, and harvesting expenses.
Beginners can also start snail farming which needs comparatively less equipment resulting in low cost.
Profit – After deducting the cost one can earn Rs 4,82,000 after 2 years.
Mud crab farming in India terms
Mud crab cultivation in India is done easily in Mumbai, Goa, Nasik and Kerala etc. They are mostly found in coastal areas from the Indian Ocean to the Malay Archipelago.
Pond size for mud crab farming
To start its cultivation 0.1 to 0.6 hectares is good enough.
Mud crab growing rate
Mud crabs grow 21 to 25 cm from the corset. When they reach 21 to 25 CM they weigh around 2 to 2.5 kg.
Mud crab feeds
Fish, prawns, bivalve molluscs and shrimps.
Mud crab maturity size
Female species S.tranquebarica reaches maturity at 12 to 14 cm in size.
S.serrate species reaches maturity at 8.5 cm only.
Water temperature
Temp – 22°C to 30°C, pH – 8.0 to 8.5 pH, salinity – 10 ppt to 34 ppt.
Harvesting time
Early morning or evening.
How long does it take to grow mud crab
5 to 6 months.
Mud crab fattening
Water fishes are retained for 20 to 22 days till they flesh out. In this process, young immature female crabs are held till the development of their gonads and mental cavity.
Pond construction
Pond construction is required in this farming and the pond construction price may be around Rs 25,000.
Sluice gate for water exchange
A sluice gate is required for water exchange. It is necessary in crab farming and available online and offline.
