BACKGROUND Conservation of marine ecosystems will require a holistic understanding of fisheries with concurrent spatial patterns of biodiversity. METHODOLOGY/PRINCIPAL FINDINGS Using data from the UK Government Vessel Monitoring System (VMS) deployed on UK-registered large fishing vessels we investigate patterns of fisheries activity on annual and seasonal scales. Analysis of VMS data shows t...

The fundamental aim in fisheries management is to determine an optimal fishing effort for sustainably harvesting from a replenishable resource. The current management objective of Australia’s Northern Prawn Fishery is to maximize the long-term net economic return following Australian government policy, resulting in an average recent catch of tiger prawn species of about 1,250 tons only. However...

Currently, politicians, university representatives, scholars and leading NGOs share a strong belief in the ability of educational systems to generate positive attitudes to sustainable development (SD) among citizens, with the idea of Education for Sustainable Development (ESD) as perhaps the most apparent expression of this conviction. The aim of this paper is to investigate whether ESD might h...

Length-Based Spawning Potential Ratio (LB-SPR) model was applied to describe the status of Javelin grunter, Pomadasys kaakan in the Persian Gulf and Oman Sea. From April 2002 to March 2019. 45,489 specimens were collected from fish landing sites monthly, and their length (FL) and weight were measured. The results of the present study showed that different gears captured most of the P. kaakan be...

The objective of U.S. fisheries management, as mandated by National Standard 1 of the Sustainable Fisheries Act of 1996, is to maintain fish stocks at levels sufficient to produce maximum sustainable yields (MSY). Mandated levels of fishing may be less than MSY but are not to exceed these levels. MSY, of course, has been a highly elusive goal (Larkin 1977). Operationally, National Standard 1 ha...

An agent–based bioeconomic fishery model was developed to assist in the design and evaluation of management instruments in an input controlled fishery. The agent–based structure of the model enables the choice of management instruments to be tailored specifically to account for the competitive ‘race to fish’ behavior observed in input controlled fisheries. The optimal season length and capital ...

Ongoing declines in production of the world's fisheries may have serious ecological and socioeconomic consequences. As a result, a number of international efforts have sought to improve management and prevent overexploitation, while helping to maintain biodiversity and a sustainable food supply. Although these initiatives have received broad acceptance, the extent to which corrective measures h...

population dynamic parameters of red mullet, mullus barbatus (n=592) caught by trawlers operating in arzew gulf (algeria) in the western mediterranean were studied. samples were collected between february 2013 and january 2014. females ranged from 10.9-23.2 cm in total length and 12-149.2 g in weight whereas males length was comprised between 12.6 and 19.7 cm and weight between 21.3 and 99.9 g....
