Danajon Bank Danajon Bank The Danajon Bank ecosystem � Only double barrier reef in the Philippines � High biodiversity and the most habitat-rich CAMOTES SEA fisheries ecosystem in the Central Philippines Danahon Bank � Extensive coral reef, mangrove and seagrass Leyte habitats Canigao Channel Talibon � Traditional fishing ground for reef fishes, rabbit Bohol Strait fishes and many small pelagics � Traditional fishing ground for blue crabs, shrimps, Panglao Island squids, sea cucumbers BOHOL SEA Threats to the marine ecosystem � Degraded corals - living coral is less than 25% � Heavily exploited – demersal biomass density is 0.44 t/km 2 � Illegal and destructive fishing – dynamite, Danish seine, trawl, fine meshed nets � Mangrove cutting, illegal conversion, siltation

EBFM: from concept to practice EBFM: from concept to practice EBFM Recommended Actions: 1. Delineation of ecosystem boundaries Basic Elements of the FISH Project’s EBFM 2. Characterization of the dynamics of the Approach: ecosystem and determination of habitat � Incremental understanding of the needs of important organisms dynamics of the marine ecosystem the 3. Development of indices of ecosystems’ defined boundary health as targets for management � Early fisheries management actions on 4. Development of conceptual model of the obvious fisheries exploitation (gear?) food web and assessment of how removals are related to trophic structure issues � Immediate fisheries management 5. Assessment of institutional elements of the ecosystem which most significantly interventions for species that constitute a affect fisheries large portion of the food web (economic importance?). 6. Development and implementation of strategies such as management planning, � Development of governance system that zoning schemes, gear/species-specific is responsive to ecosystems approach management, registration & licensing, law (scale?) enforcement, MPAs 7. Establishment of governance system that is responsive to ecosystems approach 8. Development of long-term monitoring schemes
EBFM: from concept to practice EBFM: from concept to practice Control Mechanisms: � Network of marine protected areas � Species-specific management (spatial and temporal close season) � Gear restrictions and size limits � Registration and licensing � Zoning of fishing and water activities Cross-cutting initiatives: IEC, Policy, Law Enforcement

Species specific management Species specific management Rabbit fish ( Siganus canaliculatus ) � Close season during spawning season of rabbit fish - 4 th 5 th and 6 th day after the new moon - monthly for the entire year or for a few months only � Banning of fine meshed gears catching rabbit fishes � Banning of selling of rabbit fishes during close season
Species specific management Species specific management 12 cm Blue crab ( Portunus pelagicus ) � Ban on catching and selling of berried females � Size limits (12 cm carapace width?) � Minimum crab gillnet mesh size of 10 cm (4 inches) � Impounding berried females (7 days?) � Zoning of crab fishing gears

Fisheries monitoring Fisheries monitoring Summary of observations from base line and monitoring activities � Emphasized the severity of the overfishing problem � Motivated partners and stakeholders’ commitment � Confirmed observed increases in catch rates � Showed which fishing gears benefited from initiatives � Highlighted the fact that illegal fishers benefit the most from management initiatives
Other measurable project Other measurable project results results � Inter-municipality arrangements � Adoption of CRM as a basic service (building on CRM) � Multi-year municipal CFRM Plan – codifying fisheries ordinances � Establishment MPAs – network of MPAs (about 30) � Training of people’s organizations in MPA management � Ordinances regulating mesh sizes, ban on active gears � Ordinances on closed seasons and ban on catching of gravid individuals � Fishers and fishing boats registration system � Establishment of coastal law enforcement units - both at municipal (MCLET) and MPA level (SET)
