Understanding and mitigating seabird bycatch in the South African pelagic longline fishery
… populations worldwide, with trawl, gillnet and longline fisheries considered the most destructive to seabird populations. Seabird bycatch from trawl and gillnet fisheries has been significantly reduced in recent years, but large numbers of seabirds are still killed annually by longline …

Sea turtle bycatch by the U.S. Atlantic pelagic longline fishery: A simulation modeling analysis of estimation methods
The U.S. pelagic longline fishery catches 98% of domestic swordfish landings but is also one of the three fisheries most affecting federally protected sea turtles (Crowder and Myers 2001, Witherington et al 2009). Bycatch by fisheries is considered the main anthropogenic threat to sea turtles (NRC …

Spatial dynamics modeling for data-poor species using examples of longline seabird bycatch and endangered white abalone
… was seabird bycatch from the U.S. Atlantic pelagic longline fishery, which focused on rare events/species for which data are generally characterized by a high percentage of zero observations. The other example was endangered white abalone off the California coast, which focused on endangered …

Understanding and mitigating vulnerable bycatch in southern African longline and trawl fisheries
… and sharks in fishing operations, in particular longline and trawl fisheries, which have been widely held responsible for their declining population s and threatened conservation status. This thesis addresses the issue of bycatch in a holistic manner, taking into account that species, whether …

Ecology and conservation of albatrosses and petrels at sea off Brazil
… had differing levels of sexual dimorphism. The pelagic seabird community sampled comprises birds from different ages and breeding status according to species. Skewed Adult Sex Ratio (ASR) has been proposed as a common pattern in birds, frequently biased towards males and with larger biases in …

Advancing Fisheries and Aquaculture Management with Machine Learning: Bycatch Risk Prediction and Autonomous Mortality Modeling
Machine learning is proving to play an increasingly important role in many fields, including ecology and fisheries sciences. Machine learning models offer many advantages over traditional statistical analysis methods, such as being well suited for analyzing large data sets, capable of incorporating …
