Dynamic Interdependence between Anglers and Fishes in Spatially Coupled Inland Fisheries

چکیده

The cumulative harvest pressure exerted by recreational anglers can be intense in some locations. Sustainable management and conservation of inland fisheries requires an understanding the spatial ecology fish-angler interactions (e.g., direct, indirect, feedback). Advancement towards this goal study complex interdependencies human natural systems, which achieved, part, looking beyond wetted confines individual waterbodies broader angling landscape. It has been hypothesized that fish stocks should experience strong reductions areas near large aggregations where fishing effort is presumed to greatest. To test hypothesis, we examined a feedback effects among anglers, bluegill sunfish Lepomis macrochirus, largemouth bass Micropterous salmoides across (n = 29 reservoirs) using path analysis structural equation modeling. We found imparted detectable on (direct) (indirect) landscape, attributed (1) short travel distances individuals at local scales (<40 km), (2) spatially numerically heterogeneous distribution (i.e., within counties) regional scale. Our identified presence emergent landscape-scale feedback, driven angler numbers, mediated via populations, manifested as variable movements anglers. These dynamics collectively shaped landscape suite highlight relationships between fishes Consideration direct indirect from aid prioritizing or identifying need management, conservation, public outreach, education, improve how changes one many species may other social, ecological, economic systems.

Luring anglers to enhance fisheries.

Current fisheries management is, unfortunately, reactive rather than proactive to changes in fishery characteristics. Furthermore, anglers do not act independently on waterbodies, and thus, fisheries are complex socio-ecological systems. Proactive management of these complex systems necessitates an approach--adaptive fisheries management--that allows learning to occur simultaneously with manage...

Inland capture fisheries

The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies f...

Fluctuating Fisheries in Africa's Inland Waters: Well

This paper evaluates evidence that fish stocks in Africa's inland waters are climate-driven and cannot be stabilized by conventional fisheries management measures. We draw on published material and our own recent and on-going research in Lake Chad and the East African Great Lakes area to propose that fisherfolk's livelihood strategies are well adapted to both seasonal and inter-annual climate-i...

Ecosystem approach to inland fisheries: research needs and implementation strategies.

Inland fisheries are a vital component in the livelihoods and food security of people throughout the world, as well as contributing huge recreational and economic benefits. These valuable assets are jeopardized by lack of research-based understanding of the impacts of fisheries on inland ecosystems, and similarly the impact of human activities associated with inland waters on fisheries and aqua...
