Fisheries Economics, Marketing and Entrepreneurship
Fisheries Economics, Marketing and Entrepreneurship
This domain tests farm and enterprise economics: costs, returns, break-even, marketing channels, and enterprise planning.
Core rules
- Fixed costs (pond lease, depreciation, equipment) do not change with output; variable costs (seed, feed, labour, fuel) do.
- Gross income = yield × price. Net income = gross income − total cost. Benefit–cost ratio (BCR) = gross income ÷ total cost; BCR > 1 indicates viability.
- Break-even price = total cost ÷ marketable yield. Break-even yield = total cost ÷ price.
- Marketing channels run from producer to consumer through wholesalers, retailers, or cooperatives. Each intermediary adds a margin but may add services such as transport and cold storage.
- A bankable project report needs assumptions, cash flow, repayment schedule, and risk analysis.
Worked example
A 1 ha pond yields 3,000 kg. Total cost is ₹1,50,000 and farm-gate price is ₹80/kg. Gross income = 3,000 × 80 = ₹2,40,000. Net income = ₹90,000. BCR = 2,40,000 ÷ 1,50,000 = 1.6, so the enterprise is viable. Break-even price = 1,50,000 ÷ 3,000 = ₹50/kg. If price falls below ₹50/kg, the farm makes a loss.
Traps
Do not ignore family labour, depreciation, and interest; do not confuse gross income with profit; do not use total stocked weight instead of marketable yield; and do not call a BCR of 0.8 viable.
