Abstract
Results from a survey of 105 fishing groups of capture Fisherfolk in 1998 showed that the average number of fishers per fishing group was two (2) and that the average number of hours spent fishing per group was nine (9) in addition. an average day u these 105 groups yielded some 1.401 kg of assorted fish belonging to 22 fish species Tilapia constituted forty-two (42) percent of this daily catch The different fish species caught in Taal Lake varied in prices ranging from P10/kg to P350ikg The weighted average price of all fishes. including tilapia. was P65/kg while the weighted average price without tilapia was P76/kg The total gross income per day of all 105 groups was P91 705 with each fisher getting P527 average gross income per day By ratio and proportion if per fishing group caught 13 34 kg per day. and if there were 2.761 subsistence fisherfolk households in 1998. the total catch of capture fishery in 1998 was 13.443.585 kg Gross income for this catch at P65/kg would be P873.833 032 for that year Assuming that fishing costs would amount to 30% of the value of the catch total net annual income for all fisherfolk households would be P611.683.122 The estimated total annual fish production in Taal Lake in 1998 based on this survey of 105 open catch fisherfolk and 70 fish cage operators was 67.445.085 kg. This translates to a gross income of P3.573.908.032. Eighty percent (80%) of this income was derived from fish cages The estimated difference between the total annual net incomes from fish cages and capture fishery was P298.627.878. The difference in incomes between the two groups of fishers should be viewed with the following externalities issues in mind
1 foregone income of capture fishery imposed by fish caging operations
2 wide disparity in fish prices among fish caught in the open and Napo raised in fish cages
3 loss in biodiversity, both actual and potential,
4 pollution costs. and
5 welfare and equity considerations
