Abstract
India is a land of diverse topography, climate and
natural resource. There are 12 major rivers and 48 lesser rivers
with a total catchment area of 277.6 million hectares. The fresh
water resources of the country, which are varied, harbor 587 species
of finfish and account for 9.3 percent of global inland fish production.
India's natural capital of h habitat resource has been eroded as
reflected in loss of bin-diversity and reduced fish landings. Studies
on ecology, environment, and fisheries of five major river systems,
in addition to reservoirs and flood plain lake fisheries, have been
conducted with greater focus on water quality and less on physical
habitat parameters.
The Central Water Commission is responsible for development
of all freshwater bodies, whereas the National River Conservation
Directorate is responsible for river conservation. River conservation
programs cover major rivers in ten States of the country, the 'Ganga
Action Plan' being the most important. These projects target improvement
in water quality and not fish habitat improvement. Lack of concern
for fish habitat is reflected in the planning of Farakka barrage
on the river Ganga (The Ganges) and its impact on 'Hilsa' run. Environmental
laws have not achieved desired objectives for lack of enforcement
mechanisms. Fishery scientists and resource users not involved in
the river conservation program.
The fresh water habitat management situation in India
evokes both concern and hope. Concern arises out of missing elements
in the existing fish habitat research, planning and management of
resource. The hope for the ire is our increasing awareness of the
need for better resource management and environmental conservation.
India has a responsibility to conserve these natural assets for
future generations. Potential steps are outlined.
