Ecosystem approach to aquaculture
  • An ecosystem approach to aquaculture (EAA)
    strives to balance diverse societal objectives,
    by taking account of the knowledge and
    uncertainties of biotic, abiotic and human
    components of ecosystems including their
    interactions, flows and processes and applying an
    integrated approach to aquaculture within
    ecologically and operationally meaningful
    boundaries. The purpose of EAA should be to plan,
    develop and manage the sector in a manner that
    addresses the multiple needs and desires of
    societies, without jeopardizing the options for
    future generations to benefit from the full range
    of goods and services provided by aquatic
    ecosystems (FAO 2007)

Aquaculture Advantages
  • Most efficient from of protein production
  • Easily monitored-
  • Ownship of farms helps management
  • Mature industry with promise of technological
    advances

Challenges of Marine Food Security
  • Declining fish stocks
  • Aquaculture is the only remaining growth sector
    for sea food
  • The challenge is to manage the continued growth
    of aquaculture in a responsible manner- can this
    be done?
  • Yes,.

13
Sustainable aquaculture
  • Declining fisheries aquaculture can supply the
    fisheries products to satisfy increasing demand
  • Aquaculture can provide alternative livelihoods
    to fisheries communities
  • Aquaculture can contribute to poverty alleviation
    (small-scale farming source of employment)
  • Rapid growth need to develop aquaculture in a
    sustainable way

14
  • How to implement ?
  • Way forward ?
  • Aquaculture Strengths
  • Aquaculture Problems

III. INITIAL RESULTS AND DISCUSSION (cont)
3.4. Aquaculture production situation
  • - 524.6 ha/2109 ponds high tide, low tide ponds
  • 1340 households worked in earth pond

IV. RESULTS AND DISSCUSSION
3.5. Environmental carrying capacity
25
The Ecosystem Approach
  • Principles of Ecosystem-based Management
  • Maintain structure and functioning of ecosystems
  • Human use and values are central to establishing
    management objectives
  • Ecosystems are dynamic
  • Stakeholder involvement in management
  • Adaptive based in scientific knowledge and
    continual learning through monitoring

26
  • Current Status
  • Co-Management

27
1. Introduction (cont.)
  • Fishing gears
  • mainly, bottom trawl, gillnet, squid hand line,
    falling stick cat net
  • Fishing effort 21,265 small boats (2001) and
    1,000 vessels in Central area
  • 11,372 lt45HP fishing Units (ALMRV 2002)
  • Catch of less than 30 m depth accounted for 90
  • Trend in catch (mt) 82,838 (1986) 101,450
    (1996) 242.293 (2006)
  • Trend in effort (CV) 73,137 (1986) 320.000
    (1996) 850,736 (2006)
  • Trend in relative abundance, CPUE(mt/CV/year)
    1.13 (1986) 0.32 (1996) 0.28 (2006)

28
Diversification of coastal aquaculture-approach
to reduce pressure on inshore fisheries
  • Status of inshore fish resources
  • Inshore fish resources has been declining for the
    last few decades due to
  • Intensive exploitation using different catching
    facilities with motorized boats
  • Increasing catching scope (more boats
    constructed, open new catching areas)

29
Diversification of coastal aquaculture-approach
to reduce pressure on inshore fisheries
  • Marine capture
  • 2001 2002 2003
    02/01 03/02
  • 1 481 175.3 1 575 640.4 1 647 482.0 106.4
    104.6
  • Off-shore capture
  • 584 253.6 729 225.9 845 214.6 124.8
    115.9
  • Inshore capture
  • 932 921.7 846 414.5 802 267.4
  • Inshore/total
  • 63.0   53.7 48.7

31
Diversification of coastal aquaculture-approach
to reduce pressure on inshore fisheries
  • 2. Government policy to support maintain
    inshore fishery resources
  • To reduce pressure on inshore fishery, Government
    plans to reduce number of fishing boats up to
    50,000 for inshore fisheries by the end of 2010.

32
Diversification of coastal aquaculture-approach
to reduce pressure on inshore fisheries
  • 2. Government policy to support maintain
    inshore fishery resources
  • As a result, some 35.000 boats are going to be
    diminished and approximately 40 of 862 887
    labors have to be engaged in new jobs

33
Aquaculture certification
  • Increasing concerns on sustainability
  • Increasing demand willingness to pay for
    sustainable aquaculture products
  • Corporate envl/social responsibility
  • Increasing number of aquaculture certification
    schemes
  • Confusion/concerns
  • Guidelines in preparation

34
Marine Stewardship Council (MSC)
  • Environmental certification for fisheries
    (co-founded by Unilever and WWF), taking market
    approach
  • Growing number of fisheries have eco-label brand
    dozen more in assessment or pre-assessment
  • Assesses fisheries on environmental and
    sustainability standards similar to FAO Code of
    Conduct e.g.
  • Stock sustainability
  • Management systems
  • Ecosystem impacts
  • Process 1) Pre-assessment and 2) Full Assessment
