| description | Gillnets contribute a sign if i cant portion of fish
production in the Philippine fisheries sector, as well as in
Guimaras Strait and adjacent waters. It has been found out
however, that many small-scale or municipal fishermen, to which
the gillnet fishermen belong are living below the poverty
threshold. Moreover, a number of studies and available
secondary data showed the evident overfishing in Guimaras
Strait and adjacent waters.
This study examines the socio-economic profile,
profitability and economic efficiency in gillnet fishing in
Guimaras Strait and adjacent waters.
The socio-economic profile revealed that most of the
gillnet fishermen attained elementary or high school level of education. Average household size was 5.7 members while 71 percent of the households were dependent on only one income
earner in the family. Sixty one percent of the households
depended on fishing as the only source of income. The study
also found that there were other employment alternatives, aside
from fishing, which were available for the gillnet fishermen.
Costs and earnings analysis showed that both drift
gillnets and bottomset gillnets earned fishing incomes below
that of the national poverty threshold. Encircling gillnets,
meanwhile, earned 68675.68 pesos, the highest of the three gear
types.
The normalized restricted translog profit function was
used to assess whether gillnet fishermen were able to maximize
profits and to examine relative economic efficiency. The
results which was estimated using the seemingly unrelated
regressions (SUR) technique, revealed that all gillnets were
not able to maximize profits based on pooled regressions and
indi vidual gear type regressions. Encircling gillnets were
found to be the most economic efficient while the drift
gillnets were found to be the least economic efficient.The price elasticity of demand for labour was found to be
inelastic (-0.79). Own price elasticity for fuel was close to
unity (-0.96 ), while that for crew provisions was quite elastic
(-1. 38 ). Cross price elasticity estimates revealed that the above (three) variable inputs were substitutes at varying
degrees. Input demand elasticities for labour, fuel, and crew
provisions with respect to net mesh size suggest that bigger
net mesh size would lead to lower labour and fuel use, and
lower crew provisions.
The results also showed that increase in fish prices will
increase labour, fuel and crew provisions use. The estimated
own price elasticity of output or fish catch implied the
evident overfishing in Guimaras Strait and adjacent waters.
This finding confirms the assessment of previous studies and
the suggestion of secondary data about the status of the
fishery. |
