Notes

¹. Equipment and Gear
Canoe dimensions are about 7 m in length; 1.2 m beam. Nets are assumed to be 30 in number.

². Gross Revenue
Assumes a catch rate (outer waters) of 5 kg/net/day for 275 fishing days/year. Beach price for Nile perch is taken as Shs. 2.50/kg.

³. Operating Costs
Crew size is assumed to be 3 out of 4 persons working in rotation. The crew is expected to take part of the catch (3 kg/day) for autoconsumption, and to receive other food (maize meal) supplements worth Shs. 25/day. The catch share for the crew is taken as 20% and the cooperative society deduction 10%, figured after crew shares are apportioned. The annual maintenance allowed is 20% of the investment. Depreciation is calculated on the basis of a replacement time of 2 years for nets and 4 years for canoes.

⁴. Management Opportunity Cost
The owners opportunity cost is reckoned at 2 times the minimum wage, assumed to be Shs. 600/month. It is further assumed that the owner is working half time.

⁵. Net Revenue
Return to capital is gross revenue less all costs. Rate of return on investment is return to capital divided by capital investment. Net revenue to owner is the return to capital plus the opportunity cost of management. Total revenue to a crew member is crew share plus benefits divided by a total crew size of four.

NOTES

¹. Equipment and Gear
Canoe dimensions as in Table 2.6. Nets are assumed to be 60 in number, or twice that of non-motorised units.

². Gross Revenue
Catch rate (outer waters), fishing days, and beach price for Nile perch as in Table 2.6.

³. Operating Costs
Crew size for motorised units is assumed to be 3 out of 5 persons working in rotation, or one more than for non-motorised units. Fish and other food for the crew are as in Table 2.6. The catch share for the crew is taken as 15%, and the cooperative society deduction 10%, figured after crew shares are apportioned. Fuel per fishing day is 20 1, at Shs. 10/1. Oil per fishing day is 500 ml at a cost of Shs. 11. Maintenance is reckoned at 20% of investment. Depreciation on canoe and nets is as in Table 2.6. Engine life is assumed to be 6 years.

⁴. Management Opportunity Cost
Figured as in Table 2.6, except that the owner of a motorised unit is assumed to be working full time.

⁵. Net Revenue
Elements as in Table 2.6. Outboard units may also operate as “fish ferries”, collecting catches from other boats and transferring them to landing sites. The rate of profit for such businesses is presumably much higher than for fishing alone.
