The ecological setting of North Sea fisheries
Fisheries research has traditionally been largely concerned with direct interactions between fishing activ ities and individual fish stocks with a view of optimizing yields. This single species approach has been the basis for the common fisheries policy of the EEC aimed at managing fish stocks by means of catch quota. Although exploitation is undoubtedly a most important factor in the populatio...
متن کاملModelling potential impacts of bottom trawl fisheries on soft sediment biogeochemistry in the North Sea†
Bottom trawling causes physical disturbance to sediments particularly in shelf areas. The disturbance due to trawling is most significant in deeper areas with softer sediments where levels of natural disturbance due to wave and tidal action are low. In heavily fished areas, trawls may impact the same area of seabed more than four times per year. A single pass of a beam trawl, the heaviest gear ...
متن کاملAssessment of Accumulation and Potential Health Risk of Cr, Mn, Fe, Cu, and Zn in Fish from North-Eastern Mediterranean Sea
Heavy metal accumulation in aquatic organisms has been an important issue due to environmental pollution resulting from anthropogenic activities. In this study, Cr, Mn, Fe, Cu, and Zn in the selected fish species (Mullus barbatus, Solea solea, and Siganus rivulatus) from three consecutive bays (İskenderun, Mersin, and Antalya from North-Eastern Mediterranean Sea) were considered to provide some...
متن کاملQTL mapping of forage yield and forage yield component traits in Sorghum bicolor x S. sudanense.
The sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense) is an important forage crop. However, little is known about the genetic mechanisms related to forage yield and the 4 forage yield component traits in this forage crop. In this study, a linkage map was constructed with 124 assigned SSR markers using an F2 mapping population derived from the crossing of sorghum Tx623A and sudangrass S...
