APPENDIX 2: ANNUAL INCOME DIFFERENT TYPES OF GEAR

I. NET FISHERY

Table 20: Annual income net fishery (ZK)

Assumptions

1. Number of fishing days in a year is based on the average number of fishing days obtained from the questionnaire (time of the year they fish times fishing frequency).

2. Total annual catch is based on the number of fishing days times the average number of fish caught per fishing day.

3. Depreciation periods:   Canoe 2–3 years
   Net 2–3 years

   The technical lifespan¹⁰ was used to calculate the depreciation period. The current replacement cost of the asset divided by the expected years of technical life gives the depreciation. The annual depreciation is thus constant and it assumes that there is no salvage value at the end of its technical life.

4. Repair costs:   Canoe 0%
   Net 2% (ZK 41 per year)

5. Payment helpers:

6. Selling price of fish; the size distribution for each species caught as well as the species composition of the. catch was calculated for the different types of gear and for each reservoir. Estimates were thus obtained for the weighted price of 1 fish at May 1990 prices. The catch composition was as follows:
   Kangombe
   Bream: 60% Catfish: 33% Other: 7%
   Average price for 1 fish estimated at ZK 5
   Makungwa
   Bream: 60% Catfish: 30% Other: 10%
   Average price for 1 fish estimated at ZK 9
   Lutembwe
   Bream: 55% Catfish: 28% Other: 17%
   Average price for 1 fish estimated at ZK 4

7. Revenues were divided into fish for home consumption, for distribution, for barter and fish for sale. For comparative purposes even the fish for the first 3 categories was assigned a market value.
   Kangombe Home consumption: 46% Distribution: 7% Barter. 11% Sale: 36%
   Makungwa Home consumption: 26% Distribution: 11% Barter: 4% Sale: 59%
   Lutembwe Home consumption: 54% Distribution: 16% Barter: 0%Sale: 30%

8. Not all fishermen use a canoe. The following represent the percentages of fishermen who do use it: Makungwa: 33%, Kangombe: 100%, and Lutembwe: 36%

II. TRAP FISHERY

Table 21: Annual income trap fishery (ZK)

Assumptions

1. The number of fishing days, total annual catch and the selling price of fish has been calculated as described under net fishing. The outcome, however, is different.

2. Average number of traps set per fisherman:
   Kangombe: 2.5
   Chadewa: 2.4
   Makungwa: 2.2

3. No money was needed to make traps. There were no financial expenses for repairs, natural fibres were used. No expenses for bait, used mostly nshima leftovers to attract fish.

4. Catch composition:
   Kangombe Bream: 11%Catfish: 31% Barbus:58% Other: 0%
   Chadewa Bream: 22% Catfish: 29% Barbus: 37% Other: 12%
   Makungwa Bream: 19% Catfish: 45% Barbus: 29% Other: 7%

5. Weighted price for one fish:
   Kangombe: ZK 3.2
   Chadewa: ZK 3.0
   Makungwa: ZK 7.8

III. HOOK AND LINE FISHERY

Table 22: Annual income book and line fishery (ZK)

Assumptions

1. The number of fishing days, total annual catch and the selling price of fish has been calculated as described under net fishing. The outcome, however, is different.

2. Average number of lines bought per fisherman per year:
   Makungwa: 1.8, Kangombe: 1.4, and Chadewa; 2.6

3. Average price per line; when it was bought (some people made their own twine):
   Makungwa: ZK 6.8, Kangombe: ZK 9.0, and Chadewa: ZK 2.9

4. Average number of hooks bought per fisherman per year:
   Makungwa: 3.5, Kangombe. 2.0, and Chadewa: 5.4

5. Average price per hook:
   Makungwa: ZK 1.4, Kangombe: ZK 1.7, and Chadewa: ZK 1.4

6. Catch composition Hook and Line Fishery:
   Makungwa Bream: 38% Catfish: 27% Barbus: 24% Other: 11%
   Kangombe Bream. 48% Catfish. H% Barbus: 42% Other: 0%
   Chadewa Bream: 27% Catfish: 27% Barbus: 36% Other: 11%

7. Weighted price for one fish:
   Makungwa: ZK 6.5, Kangombe: ZK 2.8, and Chadewa: ZK 3.0

IV. FISHERY WITH OTHER GEAR

Table 23: Annual income fishery with other gear (ZK)

Assumptions

1. The number of fishing days, total annual catch and the selling price of fish has been calculated as described under net fishing. The outcome, however, is different.

2. No financial expenses for gear nor repairs.

3. No bait was used for these methods.

4. Catch composition;
   Kangombe Bream: 14% Catfish: 57% Barbus: 29% Other: 0%
   Makungwa Bream: 16% Catfish; 58% Barbus: 21% Other: 5%
   Chadewa Bream: 18% Catfish: 52% Barbus: 23% Other: 7%

5. Weighted price for one fish;
   Kangombe: ZK 5.4, Makungwa: ZK 9.2, and Chadewa: ZK 4.0

¹⁰ Technical life span means the time up to when the equipment is technically impossible to use.
