Definitions l Marine Protected Area “ Areas designated for special protection to enhance the management of marine resources” (NRC 2001) with “year-round protection” l (NOAA 2001) Marine Reserve “zones within an MPA where removal or disturbance of resources is prohibited” = “no-take” areas (NRC 2001)

Impetus for MPA Public Process Public concern with fishery failures At least 25% of world’s fisheries are overfished l Examples of recent Alaskan fishery failures: l – – l Dungeness crabs: Yakutat, PWS, Cook Inlet Red king crab: Kodiak Shrimp: PWS, Cook Inlet, Kodiak/Westward Rockfish: local depletions Historic Alaskan “fishery” failures – Bowhead whale – Steller’s sea cow

Impetus for MPA Public Process (2) Executive Order 13158 (2000) – Directive to develop national system of MPAs l Public proposals to Board of Fisheries, 2001/02 – Proposals 42 & 402 (incl. PWS), 424 for Marine Reserves l ADF&G staff interest in MPAs as fishery management tools l Mitigation to meet provisions of Magnuson-Stevens Act (1996) – Essential Fish Habitat (EFH) l – Habitat Areas of Particular Concern (HAPC) VS. l Industry concern for further loss of fishing areas

ADF&G’s Role Recommendations to the Board of Fisheries Focus on reserves in relation to fisheries – Recommendation for process l l Goals and uses of MPAs in Alaska Enhanced public participation Site selection, size, and other design criteria Monitoring and evaluation of effectiveness – Literature review of the scientific basis – Catalogue and GIS maps of areas – Review of legal process for designating MPAs – Review of programs in other jurisdictions: Federal U. S. , BC, WA, OR, CA

ADF&G Task Force l Commercial Fisheries Division – Earl Krygier, Denby Lloyd, Kristin Mabry, Tory O’Connell, Charlie Trowbridge, Doug Woodby (chair) l Habitat Division – Janet Hall-Schempf l Sport Fish Division – Scott Meyer l Wildlife Conservation – Bob Small l Commissioner’s Office – Rob Bosworth Not a public body l Recommendations out for review, ~ 2 -3 months.

Goals for MPAs and Reserves l Habitat protection – e. g. , corals l

Goals for MPAs and Reserves l Habitat protection – e. g. , corals l Conserve biodiversity l Improve fishery management – Bet hedging against risk – Reduce exploitation rate – Protect spawning and nursery areas l Provide baseline environmental data

Conserving Biodiversity (Inside Reserves) Reserves are effective for increasing: – Fish abundance: 2 X

Conserving Biodiversity (Inside Reserves) Reserves are effective for increasing: – Fish abundance: 2 X (Halpern in press) – Average fish size – Species richness (usually) These results are from mostly sedentary species in tropical reef systems Results not surprising (in hindsight) – Exponential increase in fecundity with fish size

Reserves as Fishery Management Tools Q: Does fishery yield increase outside reserves? – A

Reserves as Fishery Management Tools Q: Does fishery yield increase outside reserves? – A major concern for industry A: Depends on many factors, including dispersal of larvae, juveniles, and adults. – In theory, depends on assumptions (Hastings and Botsford 1999, Guénette et al. 2000) – Experimentally, hard to assess – In practice: l l sometimes yes (Murawski et al. 2000, Roberts et al. 2001) sometimes no (Frank et al. 2000)

Some Lessons from Georges Bank All four species had been heavily exploited l Greatest benefits for most sedentary species l mobility: Cod>Haddock>Flounder>Scallop l Placement of closed areas is important – Spawning areas – Juvenile rearing areas “Source” areas as opposed to “Sinks” l Not a controlled experiment – Other restrictions contributed to increases in SSB l Fishing effort is still excessive

Alternative Lesson: Scotian Shelf Juvenile haddock closed area, 1987 (Frank et al. 2000) l

Alternative Lesson: Scotian Shelf Juvenile haddock closed area, 1987 (Frank et al. 2000) l No effect on recruitment or survival – – l Previously over-exploited – hard to recover Large-scale environmental changes (cooling) Older fish not protected (outside closed area) Not a complete closure – fixed gear allowed until 1993 Closed areas alone are not sufficient – Need additional control measures

Reserves as Controls Purpose: to distinguish fishing or other human-induced effects from environmental effects

Reserves as Controls Purpose: to distinguish fishing or other human-induced effects from environmental effects Examples: – Glacier Bay – world’s largest temperate marine reserve USGS, NPS, ADF&G cooperative research agreement – Sea urchin and sea cucumber fishery control areas – SE

Dive Fishery Closed Areas - SE Alaska Sea cucumber closures for subsistence protection (14)

Dive Fishery Closed Areas - SE Alaska Sea cucumber closures for subsistence protection (14) l Sea lion rookeries (4) l Research controls (4) l – sea urchins – sea cucumbers Sampling for l l l density growth recruitment

Reserves as Controls Needs: l Review existing closures and available data – Funding issue

Reserves as Controls Needs: l Review existing closures and available data – Funding issue l Review the existing fisheries and needs for closures – Fisheries as experiments: most lack controls Public support l Careful experimental design l – Consider effect of displaced effort

Summary & Conclusions l ADF&G’s program – Recommending a public process l Significant public

Summary & Conclusions l ADF&G’s program – Recommending a public process l Significant public (stakeholder) process needed – Not recommending specific closed areas – Opportunity to learn from mistakes elsewhere l Reserves are – No panacea for fisheries – Tools, useful in combination with other fishery management measures – Important for ecosystem monitoring
