A machine learning approach for protected species bycatch estimation

Frontiers in Marine Science
IntroductionMonitoring bycatch of protected species is a fisheries management priority. In practice, protected species bycatch is difficult to precisely or accurately estimate with commonly used ratio estimators or parametric, linear model-based methods.

Descriptive and spatial analysis of bycatch in tuna purse-seine fishery in the colombian Pacific Ocean, with an elasmobranch approach

Ocean and Coastal Research
Bycatch species are as important as target species in the challenge of comprehensive fishery management. This is especially the case for vulnerable species such as elasmobranchs in offshore areas of the Colombian Pacific Ocean (CPO), for which ...

Morphometric characteristics of Antarctic krill (Euphausia superba) and finfish bycatch in the krill fishery in the waters of South Orkney Islands during the 2022/23 fishing season

Frontiers in Marine Science
Determination of bar spacing of bycatch reduction devices (BRDs) should consider species composition and morphometric characteristics (particularly width) of target species krill and bycatch. This study conducted a scientific investigation of the finfish

Bycatch in marine fisheries

, 2012
A review of the significant contributions in the peer-reviewed literature indicates that the discarding of marine fish known as bycatch remains one of the most significant problem facing fisheries managers. Bycatch has negative affects on marine biodiversity, is ripe with ethical and moral issues surrounding the waste of life from increased juvenile ...

From bycatch to target

, 2023
Colorectal cancer is one of the leading causes of the death worldwide. Prevention of colorectal cancer could be established by detecting and removing its precursors lesions: colonic polyps. Besides adenomas, up to 30% of all colorectal cancers (CRCs) arise from precursors via the serrated pathway.

Predicting Effort and Protected Species Bycatch Under an Effort Limit or Take Caps [PDF]

Many production processes feature joint production of a desirable output with an undesirable byproduct. Producers and consumers of the desirable output mutually benefit at the expense of non-consumers, who bear external damage costs imposed by production

Evaluating the quality of bycatch data and bycatch estimates among disparate fisheries

, 2012
In 2006, the National Marine Fisheries Service, NOAA, initiated development of a national bycatch report that would provide bycatch estimates for U.S. commercial fisheries at the fishery and species levels for fishes, marine mammals, sea turtles, and seabirds.
