Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

Fisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

A global map to aid the identification and screening of critical habitat for marine industries [PDF]

, 2015
Marine industries face a number of risks that necessitate careful analysis prior to making decisions on the siting of operations and facilities. An important emerging regulatory framework on environmental sustainability for business operations is the ...

Spontaneous aortic lesions in marine turtles.

The Tohoku Journal of Experimental Medicine, 1984
Marine turtles were found to have gross aortic aneurysmal dilations and multiple, raised grayish-white plaques which resembled both the aortic lesions of Marfan's syndrome in humans and those induced by chemical manipulation in animals. Smooth muscle cells in these aortic lesions displayed considerable functional as well as morphological similarity in ...

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Analysis of Sea Turtle Bycatch by Andalusia Pelagic Longline Fleet in the Northeast Atlantic

Fisheries Oceanography, EarlyView.
ABSTRACT The Northeast Atlantic is one of the most crucial foraging grounds for juvenile loggerhead (Caretta caretta) and leatherback turtles (Dermochelys coriacea), while also serving as an important fishing area for the Andalusia surface longline fishery. The main aim of present study is to assess the sea turtle interaction with the Andalusia pelagic

Multi‐objective maritime vessel routing with safety considerations

International Transactions in Operational Research, EarlyView.
Abstract The routing of maritime vessels is a challenging optimization problem that involves finding an adequate balance between conflicting and multiple objectives. This paper proposes a methodology based on inverse optimization to find appropriate objective weights that account for conflicting objectives. To formulate the inverse optimization problem,
