The incidental capture, or bycatch, of non-target species such as mammals, birds, turtles, fish and other marine species in fisheries is recognised to be a major problem in many parts of the world. It has been estimated that 23% of the global fisheries catch is thrown back into the sea dead and wasted. Globally, the toll on all cetaceans (whales, dolphins and porpoises) is estimated to exceed 3...

Rapido trawls are used to catch sole around the coast of Italy and to catch scallops in the northern Adriatic Sea but little is known about the environmental impact of this gear. Benthic surveys of a commercial scallop ground using a towed underwater television (UWTV) sledge revealed an expansive area of level, sandy sediment at 25 m characterized by high population densities of scallops (2·82 ...

BACKGROUND Fishermen working on deep-sea vessels in the Barents and Norwegian Sea are exposed to low air temperatures, strong winds, high humidity, rain, snow and work at different intensities. Few studies have investigated the effect of environmental work factors on the physiology of this occupational group. The aim of the study was to investigate work strain and thermophysiological responses ...

Abundance indices ofyoung fish in the North Sea derived from the International Bottom Trawl Survey (JBTS) show large interannual fluctuations, which are not in accordance with ICES assessments in every case. The standard estimation of the abundance indices, however, does not explicitly account for potential influences of environmental variables on the spatial aggregation of juvenile fish and th...

Knowledge of the spatial distribution of juvenile cod is essential for obtaining precise recruitment data to conduct sustainable management of the eastern and western Baltic cod stocks. In this study, the horizontal and vertical distribution and density patterns of settled juvenile 0- and 1-group Baltic cod are determined, and their nursery areas are localised according to the environmental fac...

Abstract The iconic Atlantic cod (Gadus morhua Linnaeus, 1758) has inspired a substantial body of fishing-gear research across its geographical range, with recent efforts predominately to reduce catches this species in fisheries where their populations are fragile. Despite status and long history study compared other species, our understanding behaviour during the capture process bottom trawl r...

The subject matter of this Bachelor ́s thesis is the Eastern Baltic Sea cod. A literature review has been done regarding how environmental factors such as salinity, oxygen supply and temperature but also the size of the cod populations affects the migration patterns and the habitat choice of the cod. The result of the review shows that, when the eastern Baltic cod population is small, its area o...
