Reservoir cooperative choosing between the bank auction and the town market
A 60-member fishers' cooperative manages fishing in a 900 ha medium reservoir in Koraput district and lands about 40 tonnes of fish a year, mostly catla, rohu and minor carps. The catch is auctioned on the bank between 6 and 8 am to one middleman who pays Rs 70/kg and trucks it 60 km to town. On peak days, when 800 kg is landed, 10–15% of the fish is rejected as spoiled and sold at Rs 25/kg as poultry feed. A trader offers the cooperative a stall in the town market where fish fetch Rs 110/kg, but they would pay Rs 8/kg transport, Rs 6/kg for ice and 6% commission; a 1 tonne/day ice plant costs Rs 3.5 lakh. Separately, the cooperative's gillnets use 20 mm mesh, and the catch now includes many undersized catla and rohu of 150–250 g that fetch only Rs 40/kg. Members argue that a bigger mesh means an empty net today.
1. Show with numbers whether the town-market option justifies the ice plant, and state the assumptions and risks that could break the calculation.

Net realisation in town: 110 − 8 (transport) − 6 (ice) − 6.60 (6% commission) = Rs 89.40/kg, against Rs 70/kg at the bank - a gain of Rs 19.40/kg.
On 40,000 kg that is 19.40 x 40,000 = Rs 7.76 lakh a year.
Spoilage: about 4,000 kg a year is rejected. At Rs 70/kg it would have earned Rs 2.80 lakh; at Rs 25/kg it earns Rs 1.00 lakh, so Rs 1.80 lakh is being lost. With reliable ice most of that is recoverable.
Combined benefit is roughly Rs 9.5 lakh a year against Rs 3.5 lakh capital - payback under six months on paper, before power, labour and maintenance.
The numbers that could break it: Rs 110/kg holds only while the cooperative's volume does not flood the town market, and 40 tonnes arriving in a few weeks of peak season would depress it; a 1 tonne/day plant is marginal on an 800 kg landing day once melt loss in transport (30–40%) is counted; power cuts in Koraput are common; commission agents may raise rates; and the middleman may be providing advances that members depend on for nets and fuel. Recommendation: run a two-day-a-week trial using hired ice and a commission agent for one season, keep the bank auction for the rest, and buy the plant only after the trial price and volume are proven.
2. Explain to the members why the 20 mm mesh is costing them money, and propose how the change could be made without destroying today's income.
Read the worked answer
A 150–250 g catla or rohu is roughly four to six months old. Left in the reservoir for another six to eight months it reaches 1–1.5 kg. At Rs 40/kg the small fish returns Rs 6–10 per fish caught. At 1 kg and Rs 70–90/kg the same fish returns Rs 70–90 - and before that it spawns at least once, producing the next year's stock. So a 20 mm net is not just catching small fish; it is selling the reservoir's future at a tenth of its value and harvesting recruits before they can reproduce. This is recruitment overfishing, and in a closed reservoir there is no outside stock to make up the loss.
The trade-off is real: bigger mesh means smaller landings for one or two seasons. Ways to soften it:
- Agree the mesh change with the Fisheries Department as a formal rule for all members, so no one gains by cheating.
- Phase it: move to 35 mm this season and 50 mm next, with the peak breeding months closed.
- Use the reservoir's drawdown zone for cage or pen culture of fast-growing species to fill the income gap.
- Ring-fence part of the higher future earnings into a cooperative welfare fund for the transition months.
Members should see the arithmetic per fish, not the slogan; the numbers are what make the case.
3. What post-harvest and institutional steps must be in place before the cooperative scales up beyond the trial?
Read the worked answer
Post-harvest basics: ice at roughly 1:1 fish to ice in insulated boxes, fish gutted and washed in clean water, graded by species and size, never stacked more than about 50 cm deep, and moved in an insulated van rather than an open truck. A simple shed at the landing point with a weighing scale, a clean water point and a covered auction floor prevents much of the present damage before ice is even considered.
Institutional steps:
- A written auction system with a daily price board by species and grade, so members can see what was sold and at what price.
- Daily records of catch, price, ice used, transport cost and rejections; without these the cooperative cannot prove profitability to a bank.
- Formal cooperative or FPO registration and a bank account to access credit and to receive the town trader's payment directly rather than through one member.
- A grading and packing standard agreed with the town buyer before the first big consignment.
- A value-addition line (salted and dried fish, or a small pickle unit) for damaged and undersized fish, so nothing is dumped at poultry-feed prices.
- A written agreement with the town stall covering commission, minimum price and payment period.
Scale-up should follow proof, not hope: one season of records from the trial tells the cooperative whether the Rs 3.5 lakh ice plant earns its keep.
