Acoustic deterrence to facilitate the conservation of pantropical spotted dolphins (Stenella attenuata) in the Western Pacific Ocean

Frontiers in Marine Science, 2022
Commercial fishing constitutes an important food source but induces undesirable bycatch on animals worldwide. This study extends bycatch research geographically to the Western Pacific Ocean, filling a knowledge gap regarding bycatch and mitigation ...

Collaborative Pacific Halibut, Hippoglossus stenolepis, Bycatch Control by Canada and the United States [PDF]

, 2004
—Bycatch mortality of Pacific halibut, Hippoglossus stenolepis, in nontarget fisheries is composed primarily of immature fish, and substantial reductions in yield to directed halibut fisheries result from this bycatch.

Lures do not increase box‐trapping success of an endangered felid in South Texas

Wildlife Society Bulletin, EarlyView.
We used a randomized design and linear regression to assess whether visual (compact disc [CD] and ribbon), and olfactory (musk and ocelot urine) lures would increase capture success of three mesocarnivores (ocelots [Leopardus pardalis], bobcats [Lynx rufus], and coyotes [Canis latrans]) with box traps baited with a live bird from December 2023 to April

Estimating Cetacean Bycatch From Non-representative Samples (I): A Simulation Study With Regularized Multilevel Regression and Post-stratification

Frontiers in Marine Science, 2021
Bycatch, the non-intentional capture or killing of non-target species in commercial or recreational fisheries, is a world wide threat to protected, endangered or threatened species (PETS) of marine megafauna.

Managing South Africa's trawl bycatch [PDF]

ICES Journal of Marine Science, 2006
Abstract Walmsley, S. A., Leslie, R. W., and Sauer, W. H. H. 2007. Managing South Africa's trawl bycatch. – ICES Journal of Marine Science, 64: 405–412. Over the past few decades, it has become widely recognized that the management strategies of world fisheries must ensure sustainability of bycatch as well as of target species.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Getting to the bottom of bycatch: a GIS-based toolbox to assess the risk of marine mammal bycatch

Endangered Species Research, 2020
Marine mammal bycatch poses a particular challenge in developing countries, where data to document bycatch and its effects are often lacking. Using the Bycatch Risk Assessment (ByRA) toolkit, based on InVEST open-source models, we chose 4 field sites in ...

Using the empirical Bayes method to estimate and evaluate bycatch rates of seabirds from individual fishing vessels [PDF]

, 2007
Minimizing bycatch of seabirds is a major goal of the U.S. National Marine Fisheries Service. In Alaska waters, the bycatch (i.e., inadvertent catches) of seabirds has been an incidental result of demersal groundfish longline fishery operations. Notably,

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

Agricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.
