5.1.4 Total Capital Projection
Having obtained the fixed assets at the different value chain steps and the operating costs with and without a canoe, the total capital projection of the business can be calculated as shown in Tables 17 and
18. A comparison of the two reveals that the investment with a canoe has higher demand on capital.

5.1.5 Average Revenues from Oyster Harvesting Business Enterprise
To obtain the revenue from sale of the product, average production per producer is estimated for the respective sample sites. This considers the average quantity of oyster meat produced per producer, per
production cycle 3 days, characterized by an average of two days of harvesting and a day of processing and marketing. The production cycle calculation is the basis for calculation of the average revenue values
from which average monthly and annualseasonal revenue is estimated. The estimated average quantities of processed oysters from which estimated income revenue of oyster harvesters is estimated are both
shown in Table 19.
It is to be noted that in estimating the quantities of oysters produced, the marketing measure of one empty milk tin cup was used as the local unit of measurement of processed oysters. This was then converted to
an average net weight derived from measurements from different producers. This unit weight 150 grams is valued at the average selling price of GMD15. Assuming that there are approximately 12 possible
production cycles in a month, the monthly production value is arrived at by multiplying average price of the product by the quantity produced per cycle.
