Is catch-and-release recreational angling compatible with no-take marine protected areas?

چکیده
Marine protected areas (MPAs) have become a common conservation and management tool for reducing exploitation from the commercial and recreational fisheries sectors. However, the recreational fisheries sector has the potential to be compatible with no-take MPAs when catchand-release angling is practiced because, in theory, no fish are actually harvested. This presumes that the effects of catch-and-release angling and related activities do not cause appreciable declines in fish populations as a result of direct mortality, sub-lethal effects, or indirect effects on fish habitats, or other problems contrary to the goal of a given MPA. Here, we explore the idea that recreational catch-and-release angling may be compatible with some no-take MPAs provided there are no substantive negative ecological consequences. We argue that it is not currently possible to answer definitively the question of whether recreational catch-and-release fisheries can be compatible with no-take MPAs. Mortality rates of released fish vary extensively (between zero and near 100%) and are influenced by a number of factors including environmental conditions, fishing gear, angler behavior, and species-specific characteristics. Nevertheless, research in the field of catch-and-release is beginning to show that certain handling techniques can significantly reduce post-release mortality in fish. With appropriate regulation and angler education, catch-and-release could help enhance conservation and management goals associated with MPAs while maintaining public support and providing alternative tourism-based revenues for displaced fishers. Until sufficient data are available, research should focus on contrasting the fish community characteristics in regions with no fishing and see front matter r 2006 Elsevier Ltd.

Angling for endangered fish: conservation problem or conservation action?
Recreational angling has been implicated in population declines of some marine and freshwater fish, but this activity is rarely considered as a threat or even halted when endangered species are targeted. Indeed, in some cases, anglers are drawn to fish for rare or endangered species. Conservation-oriented behaviours such as catch-and-release are often practiced voluntarily due to the ethics of ...
متن کاملEmpirical Evidence for Species-Specific Export of Fish Naïveté from a No-Take Marine Protected Area in a Coastal Recreational Hook and Line Fishery
No-take marine protected areas (MPAs) are assumed to enhance fisheries catch via the "spillover" effect, where biomass is exported to adjacent exploited areas. Recent studies in spearfishing fisheries suggest that the spillover of gear-naïve individuals from protected to unprotected sites increases catch rates outside the boundaries of MPAs. Whether this is a widespread phenomenon that also hol...
متن کاملEffect of catch-and-release angling on growth of largemouth bass, Micropterus salmoides
Catch-and-release angling is popular in many parts of the world and plays an increasingly important role in management of recreational fisheries. Although the magnitude of catch-and-release mortality is well documented for many species, potential sublethal effects have been little studied. An experiment was conducted to assess directly the effects of catch-and-release angling on growth of large...
متن کاملSchroeder and Love.: Recreational Fishing and Marine Fish Populations
We present and review information regarding recreational angling and exploited marine fish populations in California. A comparison of rockfish assemblages among three differently fished areas (one open to all fishing, another open only to recreational fishing, and a de facto marine protected area) revealed large differences in fish density, size structure, and species composition. The area open...
متن کاملExploring the Fishing by Stake-nets inside the Qeshm Island's Marine Protected Area
High population pressure in coastal areas has led to loss in many mangrove areas. Although these areas are fish nursery grounds, but there are no accurate and up-to-date data available. In this research, the catch data in the Qeshm Island marine protected area (MPA) were investigated using 11 stake nets. Totally, 81 specimens belong to 60 genera and 63 families caught, which majority of them we...
