Pelagic Fish Behaviour During Trawl Sampling Off Angola
Large sardinella (Sardinella maderensis and Sardinella aurita) in warm waters off the coast of Africa are known to be a challenge for pelagic trawl sampling, for example during acoustic surveys for abundance estimation. We observed the swimming behaviour of sardinella mixed with other pelagic species, mainly Cunene horse mackerel (Trachurus trecae), during sampling with a pelagic trawl in the c...
متن کاملElasmobranch bycatch in the Italian Adriatic pelagic trawl fishery
Elasmobranchs are among the most threatened long-lived marine species worldwide, and incidental capture is a major source of mortality. The northern central Adriatic Sea, though one of the most overfished basins of the Mediterranean Sea, supports a very valuable marine biodiversity, including elasmobranchs. This study assesses the impact of the northern central Adriatic pelagic trawl fishery on...
متن کاملCetaceans and Pelagic Trawl Fisheries in the Western Approaches of the English Channel Cetaceans and Pelagic Trawl Fisheries in the Western Approaches of the English Channel
A joint WDCS/Greenpeace cetacean survey using conventional line-transect techniques and trialling other survey methodologies, including acoustic detection, was carried out between 21st of January and 8th of March 2004 in the Western Approaches of the English Channel. The main aims of this survey were to study the local dolphin, porpoise and whale populations, to monitor the winter pelagic trawl...
متن کاملPredicting Postrelease Survival in Large Pelagic Fish
—Sharks, turtles, billfish, and marine mammals are frequently caught accidentally in commercial fisheries. Although conservationists and fisheries managers encourage the release of these nontarget species, the long-term outcome of released animals is uncertain. Using blue sharks Prionace glauca, we developed a model to predict the long-term survival of released animals based on analysis of smal...
متن کاملAutomatic Fish Segmentation and Recognition for Trawl-Based Cameras
Camera-based fish abundance estimation with the aid of visual analysis techniques has drawn increasing attention. Live fish segmentation and recognition in open aquatic habitats, however, suffers from fast light attenuation, ubiquitous noise and non-lateral views of fish. In this chapter, an automatic live fish segmentation and recognition framework for trawl-based cameras is proposed. To mitig...
