Reducing by-catch through fishing gear modification [PDF]

, 2009
There have been considerable efforts in recent years to modify fishing gears and practices to target particular sizes and species of fish (fin and shell) and other marine organisms more efficiently. By catch consideration and gear modification play an important role in regulation of several major fisheries and new by-catch reduction devices and other ...

By-Catch: Problems and Solutions

Marine Pollution Bulletin, 2000
Abstract By-catch is one of the most significant issues affecting fisheries management today. Incidental mortality of species which are long-lived and have low reproductive rates is a conservation problem affecting marine mammals, sea birds, sea turtles, sharks and other groups. By-catches can affect biodiversity through impacts on top predators, the

Preventing Amyloid Formation by Catching Unfolded Transmembrane Segments

Journal of Molecular Biology, 2009
A subset of protein misfolding diseases, including, for example, Alzheimer's disease, is associated with the formation of highly insoluble amyloid fibrils with a beta-sheet structure. The amyloidogenic human lung surfactant protein C (SP-C) is generated from SP-C precursor, which has a C-terminal domain (CTC) that prevents SP-C amyloid fibril formation.

Sea turtle by-catch in the Mediterranean

Fish and Fisheries, 2010
Sea turtle by-catch data in the Mediterranean were reviewed and analysed with fishing effort. The results indicate over 132000 captures per year, with probably over 44000 incidental deaths per year, while many others are killed intentionally. Small vessels using set net, demersal longline or pelagic longline represent most of the Mediterranean fleet ...

Acoustic alarms to reduce cetacean by-catch

Proceedings of the 2004 International Symposium on Underwater Technology (IEEE Cat. No.04EX869), 2005
Acoustic alarms, otherwise known as beacons or pingers, are designed to transmit certain sound patterns underwater as a deterrent effect on cetaceans in the vicinity of fishing nets. The device presented here has been successfully tested in Scotland and Denmark and has been shown to reduce the by-catch of harbour porpoises during a commercial fishing ...

Exploiting sensory ecology to reduce seabird by-catch

Emu - Austral Ornithology, 2007
In a previous study, we reported that deploying small amounts of biogenic oil derived from the livers of school sharks (Galeorhinus galeus) was effective in reducing the numbers of seabirds attending fishing vessels and seabird diving activity in the Hauraki Gulf, New Zealand.
