An Option for Sustainable Management of Fishery Resources in Deepor Beel

Co-management Approach

Sujan M. Henkanaththegedara

ECS 740: Fall 2007

Outline

• Current status of the fishery– Composition & Production– Fishery regulation

• Problems– Unsustainable fishing practices– Declaration of Wildlife Sanctuary– Potential impacts of aquaculture

• Possible solutions• Community based co-management

Fishery Resources

• 61 freshwater fish species (Saikia 2005)

• 54 indigenous; 5 exotics

• 8 protected species (Wildlife protection Act, 1972)

• 20 economically important

• 11 collect for ornamental trade

Labeo calbasu

Brachydanio rerio

Nandus nandus

• Expectation: 90,000 tons/ year (Goswami and Choudhury 1990)

• Harvest: 245 kg/hectare (980 tons)

• Comparatively very high yield (AFDC, Assam)

Fishery Production

Fisher Community

• Traditional fishery

• More than 5000 people/1200 families depend on the fishery

• Community fishing during winters.

Fishery Regulation

• Authority– Assam Fisheries Development Corporation– State Fisheries Department

• Lease government parts for commercial fishery

• Private land owners also lease their private land

New Proposals

• Development of pen and cage culture for the rearing and propagation fish (Gauhati University, Assam)

• Government Authority and some interested parties propose aquaculture in fringe areas

• Declaration of Deepor Beel as a Wildlife Sanctuary

Problems Identified

1. Unsustainable fishing practices2. Declaration of Wildlife Sanctuary3. Possible impacts of garbage dumping4. Impacts of siltation5. Possible impacts of exotic fish6. Conservation implications for protected

species7. Potential impacts of aquaculture

Unsustainable fishing practices

• Impacts– Harmful fishing methods (eg. small mesh size)– Potential overharvesting (small size of fish,

possibly collapse the fishery)

• Possible solutions– Closed areas/closed seasons– Ban harmful fishing methods– Close monitoring of illegal fishing– Fisheries co-management

(Myers et al. 1997; Hambright and Shapiro 1997 )

Declaration of Wildlife Sanctuary

• Impacts– Limitations to the fishery– Serious conflicts between local people and

government – Social and economical problems in local

communities

• Possible Solutions– 10-20% core wildlife sanctuary – Rest- Reserved wetland (human activities

permitted up to some extent)

Potential impacts of aquaculture

• Impacts– Introduction of exotic species– Pollution– Eutrophication (mass fish kills!)

• Possible Solutions– A proper cost-benefit analysis – If necessary, based on native species– If necessary, locate beyond the fringe areas

What to do?

• Beel fishery is still UNDERUTILIZED.

• Need to manage the fishery PROPERLY,– To meet maximum sustainable yield (MSY)– To improve the living standards– To fulfill the local protein requirement– To reduce the unemployment

• What is the need of AQUACULTURE?

What is Co-management?• A partnership arrangement between,

– Government agencies– Local fisher community– NGOs– Other stakeholders

• Share the responsibility and authority for the management of a fishery.

• Integrate local (informal, traditional) and government management systems.

• Power-sharing between government and fishermen (Pomeroy 1998).

What is Co-management?

Fishers

Government

Assam Fish. Dev. Cooperation

State Fish. Dept.

Fisheries Stakeholders

Boat owners

Fish traders

Money lenders

External Agent

Gauhati University

Local stakeholders

Tourism

Transportation

Fisheries Management

Modified after Pomeroy 1998

Co-management

Resource-oriented studies to define fishery regulations

Monitoring the fishery

Implementing fishery regulations

Organize fisheries co-operative society

Enhance fish production and improve living standards

Active government or NGO mediation

Maintenance of fisheries co-operative society

Proper regulation of fishing permits

Banning harmful fishing methods

Social welfare
