Small-scale fisheries (SSF) are crucial for food security and poverty alleviation. Many SSF however under pressure, in need of better management paying special attention to the key seascape ecosystems which supporting them. This study investigates importance seagrass beds households their southwestern Madagascar. The specific aims this were to: i) analyze if how seagrass-associated fish contrib...
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...
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,...

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...
Ten years of research about the Neanderthal’s subsistence behaviour are presented. The study of large mammal bones is now recognized as a means of understanding subsistence behaviour (sensu lato), notably by analysing acquisition and processing strategies, as well as patterns of consumption. This paper summarizes the results of an analysis of a corpus of data from several European countries, re...
