Goal To analyze the possibility for recreational fishing to induce genetic changes in exploited fish populations, and thereby to increase awareness of such potential among stakeholders and stimulate increased research effort and long-term monitoring of fish populations exploited by angling fisheries. As a result of selective (i.e. non-random) mortality, exploitation of wild living resources can...

Individuals relying on natural resource extraction for their livelihood face high income variability driven by a mix of environmental, biological, management, and economic factors. Key to managing these industries is identifying how regulatory actions and individual behavior affect income variability, financial risk, and, by extension, the economic stability and the sustainable use of natural r...

Quantifying Sea Turtle Mortality with PSATs 1 New Discoveries in the Olfactory Capability of Sea Turtles 6 MHLC7—Evaluation and Comment 10 Compendium—Fisheries Research in Brief 11 (continued on page 2) The incidental capture of marine turtles in longline fishing gear is generally accepted to be a significant factor contributing to the decline of sea turtle populations in both the Pacific and A...

Today, fishing is the major source of mortality in many harvested fish stocks. The new high fishing mortality regime may induce evolutionary change in the harvested population, because the currently observed life-history patterns in fish stocks presumably reflect adaptation to past mortality regimes. Changes in these life-history patterns are likely to have an influence on, for example, the sus...

A stochastic age-structured population model was developed to explore biologically favourable levels of effort and closing periods within the sardine pelagic fishery in the eastern Mediterranean Sea. Results suggested that the developed age-structured model captured the observed biomass fluctuations and catches reasonably well and represents the first comprehensive investigation of alternative ...

The present study deals with the detailed investigation on population dynamics of near-threatened catfish Ailia coila (Hamilton, 1822), which inhabits Brahmaputra River India and forms an important component freshwater inland fishery, providing nutritional financial security to local community. A total 1034 individuals were collected by weekly sampling from Uzanbazar Dhubri landing centres this...
