CW: concerning predictions, there are two that are fairly robust: primary production limits possible total production, through it will not determine whether a system is stable or not. Here, Ecopath and its dynamic routines, Ecosim and Ecospace can help; equilibrium community composition responds to fishing: as you alter fishing mortality, a number of changes in abundance are predicted. Notably,...

Spatial management tools, such as marine spatial planning and marine protected areas, are playing an increasingly important role in attempts to improve marine management and accommodate conflicting needs. Robust data are needed to inform decisions among different planning options, and early inclusion of stakeholder involvement is widely regarded as vital for success. One of the biggest stakehol...

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...

This paper estimates the economic value of the North Sea cod (Gadus morhua) stock under recent catch and several recovery scenarios. The research presents results on: a) what the value of catches and biomass would have been if the EU fishing fleet had followed the International Council for the Exploration of the Sea scientific recommendations (SRs) and Total Allowable Catches (TACs) in the 1986...
