OBJECTIVE To investigate long-term trends in mortality rates for accidents to fishing vessels in the UK fishing industry from 1948 to 2008; to investigate the circumstances and causes of these fishing vessel accidents and trends in fishing vessel losses. MATERIAL AND METHODS Examination of paper death inquiry files, death registers, marine accident investigative files, annual casualty and dea...
We examined the temporal trend in mean trophic level (mTL), trophic category landing (TrC) and landing profile (LP) of the exploited marine community (49 species) in the fishing zone of Hormozgan (north of Persian Gulf and Oman Sea) from 2001 to 2011. LP had an increasing trend (r = 0.88, P<0.001), whereas, mTL of the landings showed a significant decrease from 2001 to 2011 (r = -0.69, P<0.05)....
Recreational waters should be considered as risks for Enterococcal infections in regions with high utilization and long exposure periods. The aim of this study was to investigate the resistance of Enterococci to selected antibiotics and some heavy metals [Pb+2, Fe+2, Zn+2 and Cr+2]. A total of 75 Enterococcal isolates was obtained from 54 bathing and ...
To create the new CPUE based on the fishing effort for searching skipjack fishing ground or fish school, GPS data loggers were deployed on 7 Japanese pole and line vessels(< 200 GRT) from July to September 2010. The position and speed of vessels were logged in every 1 second. Start and end time of fishing (angling) and skipjack catch (ton) of each fishing activities were recorded on the field n...
Using a bioeconomic model of the cod (Gadus morhua) and capelin (Mallotus villosus) fisheries of the Barents Sea, this study assesses the role of the fishermen’s behavior in reducing or intensifying the effects on the stocks caused by altered population dynamics. The analysis focuses on the economic development of the fisheries employing a coupled stock size–hydrography-based fishing strategy, ...
Two coral species, Porites palmata and Porites lutea, were transplanted into three distinct management areas adjacent to the Mombasa Marine National Park, Kenya: A no-fishing MPA; a gear-restricted reserve with no beach seining; and a reserve with beach seining. Corallivory by fish or breakage by fishing gear was measured over a 57-day period. Porites palmata, the branching species, was more su...

Reef fishes that exhibit predictable aggregating behaviour are often considered vulnerable to overexploitation. However, fisher knowledge of this behaviour is often heterogeneous and, coupled with socioeconomic factors that constrain demand for or access to aggregated fish, will influence susceptibility to fishing. At two case study locations in Papua New Guinea, Ahus and Karkar islands, we con...
Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists and fishery managers. Although China has applied the Beidou fishing vessel position monitoring system (VMS) to manage trawlers since 2006, little is known regarding the impacts of trawling on the sea bottom environments. In this study, continuou...
The evaluation of fish stocks exploitation is a complex task that comprehends the analysis of several types of data including information on the spatial and temporal dynamics of commercial fishing fleets. Satellite-based Vessel Monitoring Systems (VMS) is one of the best independent data sources available that can provide information on fishing fleet operations. This type of system allows the t...
