A Mixed-Method Approach for Quantifying Illegal Fishing and Its Impact on an Endangered Fish Species
Illegal harvest is recognized as a widespread problem in natural resource management. The use of multiple methods for quantifying illegal harvest has been widely recommended yet infrequently applied. We used a mixed-method approach to evaluate the extent, character, and motivations of illegal gillnet fishing in Lake Hovsgol National Park, Mongolia and its impact on the lake's fish populations, ...
متن کاملFluctuations of fish populations and the magnifying effects of fishing.
A central and classic question in ecology is what causes populations to fluctuate in abundance. Understanding the interaction between natural drivers of fluctuating populations and human exploitation is an issue of paramount importance for conservation and natural resource management. Three main hypotheses have been proposed to explain fluctuations: (i) species interactions, such as predator-pr...
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 کاملQuantifying effects of fishing on marine trophic webs
Exploited ecosystems are characterised by exports of secondary production from each fished trophic level that reduce the energy available for upper levels at ecosystem scale thus impinging on overall secondary productions. Depletion in secondary production with respect to the unfished state is here proposed as a proxy for quantifying ecosystem effects of fishing. Theoretical analysis of trophic...
