| Summary: | In Bangladesh, most of the inland open-water
fisheries had retained an open-access character in the
absence of a consistent and effective management
policy. Consequently the resulting pattern of fishing
activities is characterised by economic inefficiency.
In view of this, the current concern of the Government
is to increase economic performance of the industry
through some direct measures of control on the
allocation of fishing rights, fishing effort and fish
catch.
The objective of this research is to derive an
operational model, which can be used to analyse the
performance of the fisheries under different simulated alternatives
conditions.
of techno-economic and biological
Functions and parameters of a Base Model were
estimated by deriving two sub-models: (a) bio-economic
production and (b) the market, using regression
techniques. Both primary and secondary data were used
for empirical estimation of the sub-models.
Accordingly, the model was developed, in a
linear programming (LP) framework, to represent
various fisheries in the riverine waters of
Bangladesh. Results of the base model suggest that
the riverine fisheries of Bangladesh are capable,
under optimal conditions, of generating a total net
benefit of BOT (Bangladesh Taka) 1,383 million per
annum (US$1 = BDT32), of which 96% as producer
surplus. Also, a significant overcapacity (118%)
exists in the existing fleet in terms of application
of effort relative to the resource availability.
simulation of cost and demand changes reveal
that the effect of changes in the cost condition of
harvest will in general be related negatively to the
intensity of total effort use, total langings,
benefits and costs; while the effects of changes in
the aggregate demand on total effort, total costs,
landings, prices and net benefits will be positive.
The implication of the results for management is that intervention into the fisheries through control on effort intensity would produce substantial net benefits from the open-water fisheries. |
