Fisheries management in Caribbean countries:information needs of the policy –making process in relation to GEC & the Caribbean Food System

Fisheries Management

In the Caribbean

  • Fish is second highest source of protein
  • Employs around 130,000
  • Fisheries production – 123,366 MT
  • Significant revenue earner in some countries, e.g. Belize
  • Key sector for providing opportunities for
  • rural poor, socio-economically disadvantaged
slide3

Fisheries Management

In the Caribbean

  • Artisanal & small-scale components are significant
  • Subsistence fishing also very important
  • Fishing communities usually based in low-lying
  • coastal areas
  • Landing sites : usually sandy beaches with
  • little added physical infrastructure
  • Boats hauled onto beaches, or moored in sheltered areas
management objectives
Management Objectives
  • Biological objectives

- conservation of the resource

- protection of the ecosystem

- protection of biodiversity

  • Economic objectives

- Optimise stakeholder profits,

- generate employment opportunities

- generate revenue through trade and tourism

  • Social objectives

- food security

- poverty alleviation

- equitable distribution of economic benefits

achieving management objectives
Achieving Management Objectives
  • Resource assessment models

- Surplus production models that estimate Maximum Sustainable Yield – MSY, MEY

- Age-based and size-based models that estimate growth and recruitment over fishing reference points

- Bioeconomic models

- Ecosystem-based approaches

- Models incorporating environmental effects

  • Monitoring of catch rates as abundance index

ECOLOGICALLY ADAPTED MANAGEMENT

(Wilson and Kleban, 1992)

- Nature is non-random but unpredictable

- fish populations will vary unpredictably

within certain limits

- need to understand longer-term ecological

relationships

- more flexible management systems

slide11

GLOBAL ENVIRONMENTAL CHANGES THAT

MAY AFFECT CARIBBEAN FISHERIES

  • - Increase in sea surface temperature
  • - sea level rise
  • increased frequency of ENSO events
  • increased frequency of storms & hurricanes
  • - changes in rainfall
  • changes in sea current systems
slide12

INCREASE IN SEA SURFACE TEMPERATURE

  • Coral bleaching

- loss of biodiversity

- decreased ecosystem health and resilience

- long-term threat to food security

- decreased yield of some traditional reef species

- short to medium-term threat to food security

- investment losses

slide13

INCREASE IN

SEA SURFACE TEMPERATURE (cont’d)

  • Increased frequency of storms & hurricanes

- irreversible coastal habitat destruction (reefs, mangroves)

- beach erosion (damage to landing sites)

- vessel & gear damage

- increased fishing pressure as a result of employment shifts

- access and availability of reef fish species, lobster and conch

- changes in resource recruitment (damage to nursery areas

& changed coastal circulation patterns)

- decreased fishing days

- increase in ciguatera poisoning

Changes in resource biology

- increased growth & mortality

- changes in resource distribution

slide14

SEA LEVEL RISE

  • Coastal habitat loss

- mangroves

- loss of many landing sites

- submergence of low lying islands often used as

fishing bases

- saltwater intrusion of coastal and estuarine wetlands

  • Changes in resource abundance

- decreased stock recruitment to reef & lobster fisheries

- decreased fisheries yields

- decreased production of coastal & estuarine wetlands

slide15

INCREASED FREQUENCY OF ENSOs

  • Shifts in resource distribution

- decreased local availability of resource

  • Changes in resource abundance

- decreased stock recruitment to some fisheries

  • Investment losses
slide16

CHANGES IN RAINFALL

  • Drought

- decreased production of freshwater

and mangrove systems

CHANGES IN SEA CURRENT

CIRCULATION PATTERNS

  • Key migrations of oceanic pelagic species
  • Changes in movement of nutrient-enriched water created by upwelling effects and river discharges off Guianas-Brazil shelf
slide17

FULFILLING INFORMATION NEEDS

OF POLICY MAKERS

  • Enhancement of current baseline and monitoring

data information systems

- resource data

- fishery activity data

  • - habitat inventory data, e.g. coral reef, mangroves
  • - environmental data (SST, ocean currents, wind speed)
slide18

INFORMATION NEEDS (cont’d)

  • Research and Development of Management Advice

- biological and ecological studies

(resource biology and resource/environment relationships,

identify ecosystem indicators related to GEC)

- socio-economic studies (vulnerability assessments,

evaluation of adaptation responses, community involvement &

integrated approach)

  • - technological studies (alternative fishing practices
  • - further development of ecosystem-based fishery models
  • - risk assessment and development of precautionary &
  • participatory approaches to management
slide19

INFORMATION NEEDS (cont’d)

  • Capacity, Legislation and Infrastructure

- evaluate capacity building needs (supporting institutions, HRD

& community education and participation in management)

- evaluate new or additional infra structural needs

  • - review need for updating /introducing legislation to support
  • proposed changed policies, e.g. habitat protection
