The first Red-Sea Indo-Pacific alien moray eel in the Eastern Mediterranean is reported here. A single specimen ot Gymnothorax reticularis was captured by a commercial bottom-trawl vessel off the northern coast of Israel. Morphological and anatomical similarities with the single known Red-Sea specimen raise an old taxonomic dilemma.
Eight specimens of the slender ponyfish Equulites elongatus were collected, by otter trawl, between 6 December 2014 and 18 April 2015 from Turkish waters, off Mersin. This constitutes the second record of this species in the Mediterranean Sea and is about 530 km distant from the site of first record (Tel Aviv, Israel).
This investigation was carried out for the determination of fish species living in Bandırma Bay (Sea of Marmara). Morphometric and meristic characters of of fishes caught by trawl and various nets in Bandırma Bay in the years of 1998-1999 were examined and some morphological, ecological properties, and local names of 34 determined species are given.
The catch composition of bottom trawls is commonly refined and improved through changes in codend design. Measures like reducing the number meshes circumference or turning diamond netting by 90 degrees are well known to improve size selectivity fish species with rounded cross-sectional shape. Based on this we speculated whether same measures, if applied other parts a trawl, would provide simila...
Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern Barents Sea). Vessel Monitoring System (VMS) records and trawl marks (TM) on the seabed were used as indicators of pressure and impact of bottom trawling, respectively. Estimates ...
The identification of nursery grounds and other essential fish habitats of exploited stocks is a key requirement for the development of spatial conservation planning aimed at reducing the adverse impact of fishing on the exploited populations and ecosystems. The reduction in juvenile mortality is particularly relevant in the Mediterranean and is considered as one of the main prerequisites for t...
United Nations General Assembly Resolution 61/105 on sustainable fisheries (UNGA 2007) establishes three difficult questions for participants in high-seas bottom fisheries to answer: 1) Where are vulnerable marine systems (VMEs) likely to occur?; 2) What is the likelihood of fisheries interaction with these VMEs?; and 3) What might qualify as adequate conservation and management measures to pre...
