Biogeography of Atlantic Salmon in the Cape Breton Highlands, Canada

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Atlantic Salmon (Salmo salar) populations have experienced significant declines in recent decades. In Canada, conservation efforts are divided into 16 designatable units (DUs) to address unique regional challenges among genetically distinct populations.

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Sensitivity of angler benefit estimates from a model of recreational demand to the definition of the substitute sites considered by the angler

open access: yes, 2007
Fishery managers are mandated to understand the effects that environmental damage, fishery regulations, and habitat improvement projects have on the net benefits that recreational anglers derive from their sport. Since 1994, the National Marine Fisheries Service (NMFS) has worked to develop a consistent method for estimating net benefits through site ...
