| Summary: | In Indonesia, the present role of fish in the daily diet
is very small. This study is aimed at determining the nature
and causes of the 1011 consumption level of fish in Indonesia.
Using cross section data of 179 sampled households and 65
fresh fishmongers in the public markets, the results of this
study show that in the retail outlets of fresh fish the market
is efficient. Both fishmongers and consumers (households) in
majority indicated that fresh fish is readily available in the
market. The largest number of households bought fresh fish
regularly at least once a week. Milkfish, Mullet, Tilapia and
Tuna are the species usually purchased. The major problem when
buying fresh fish is freshness of fish.The acceptability of fresh fish varies among households,
but in general, the relative acceptability index shows that
chicken is preferred to fresh fish and beef, while milkfish is
preferred to other fish and beef.
Two models have been used in this study for estimating the
parameters of the fresh fish demand system. First, logarithmic
linear functions of demand system model-using OLS and second,
Zellner's Seemingly Unrelated Regression (SUR) model.
The logarithmic linear function of demand system of fresh
fish used in this study looks appropriate for estimating the
demand for fresh fish. The symmetry restriction on this demand
function is accepted. The Goldfeld-Quandt test applied to the
data indicates heteroscedasticity is not a problem in this
logarithmic demand system. Meanwhile Zellner' s Seemingly
Unrelated Regression (SUR) yield estimates which are
asymptotically more efficient than those obtained by Ordinary Least Squares (OLS). So, the Seemingly Unrelated Regression
have been applied in this study for estimating the demand
function of fresh fish.
With the exception of Tilapia, the findings of this study
show that the demand for fresh fish is elastic with respect to
its own price. The coefficient of own price elasticities ranged
from -0.6756 to -2.2591. While the expenditure elasticities are positive and significantly different from zero except for
Mullet.
Based on the results of this study, consumption of
fresh fish can be enhanced if the following actions are also
taken: improvement of the fish stall in public markets,
promotion of fish consumption, provision of government
subsidies on fuel for fishermen, provision of subsidies on
fertilizer, pesticides and low interest credit scheme far
fish farmers. |
