Total marine fisheries catches by CCAMLR member countries within the EEZ of Bouvet Island (or Bouvetøya, Norway) in the southern Atlantic were estimated from 1970 to 2010, including previously unreported catches from longline fisheries. Mesopelagic and demersal fish species distribution and abundance around Bouvet Island were assessed through the 20 century by various methods. Cumulative marine...

With the development of offshore and Pelagic Fisheries, continuous expansion fishing routes, corresponding ship tonnages are increasing, air pollution vessels is becoming more serious. An fishery research vessel was selected as object, emission factors were obtained according to its basic data, method based on fuel consumption adopted calculate pollutants (NO x , HC, CO PM 10 ) inventory establ...

It is commonly acknowledged that body weight of fish is a key factor in determining market value of landed catch, thus influencing optimal harvest strategies. However, in management strategy evaluations and bioeconomic modelling body size is often an overlooked economic parameter, and there are no systematic studies on prevalence of sizedependent pricing. Here we assess the presence and magnitu...

A model of a system concerning one species of demersal (inshore) fish and one of pelagic (offshore) fish undergoing fishing restricted by marine protected areas is proposed in this paper. This setup was based on the FISH-BE model applied to the Tabina fishery in Zamboanga del Sur, Philippines. The components of the model equations have been adapted from widely-accepted mechanisms in population ...

According to portfolio theory applied to fisheries management, economic returns are stabilised by harvesting in a portfolio stocks of species whose returns are negatively correlated and for which the portfolio economic return variance is smaller than the sum of stock specific return variances. Also, variability is expected to decrease with portfolio width. Using a range of indicators, these pre...

The continental shelf of the eastern Bering Sea (EBS) is highly productive, supporting some of the most valuable finand shellfish fisheries in the United States as well as large, local and migratory, populations of seabirds and marine mammals. Temperature and hydrographic structure are important components to the pelagic and epibenthic habitat that influence the distribution, behavior and inter...

On 1st April 2010, the British Government announced designation of the British Indian Ocean Territory--or Chagos Archipelago--as the world's largest marine protected area (MPA). This near pristine ocean ecosystem now represents 16% of the worlds fully protected coral reef, 60% of the world's no-take protected areas and an uncontaminated reference site for ecological studies. In addition these g...

Myers and Worm claim that their analyses of catch rates following the commencement of industrial longline fishing for tuna and billfishes show that these longline fisheries rapidly depleted the abundance of these large oceanic predators by 90% (Myers RA, Worm B. Rapid worldwide depletion of predatory fish communities. Nature 2003;423:280–3). Their analyses were published in a high profile scien...

Industrial longline fisheries cause the death of large numbers of seabirds annually. Various mitigation measures have been proposed, including the use of tori lines. In this study the efficiency of a single tori line to reduce seabird bycatch was tested on pelagic longline vessels (25-37m length). Thirteen fishing trips were carried out in the area and season of the highest bycatch rates record...

Mid-trophic pelagic fish are essential components of marine ecosystems because they represent the link between plankton and higher predators. Moreover, they are the basis of the most important fisheries resources; for example, in African waters. In this study, we have sampled pelagic fish larvae in the Eastern Atlantic Ocean along a latitudinal gradient between 37°N and 2°S. We have employed Bo...
