A bstract Interannual, seasonal, and regional variation in the diet of porpoises, Phocoena phocoena , Scottish (UK) waters was studied using stomach contents animals stranded between 1992 2003. Most samples came from east coast (including many porpoises killed by bottlenose dolphins), with smaller numbers west Shetland. The most important prey types, terms contribution number mass, were whiting ( Merlangius merlangus ) sand eels (Ammodytidae). Multivariate analysis confirmed existence...
Fish aggregating devices, or FADs, are used widely in developing countries to concentrate pelagic fish, making them easier catch. Nearshore FADs anchored close the coast allow access for rural communities, but despite their popularity among policy makers, there is a dearth of empirical analysis contributions supply fish and fisheries management. In this paper we demonstrate that nearshore increased four communities Solomon Islands. Estimated total annual catch ranged from 4300 12 000 kg...
The population of Calanus finmarchicus in the North Sea is replenished each spring by invasion from an overwintering stock located beyond shelf edge. A combination field observations, statistical analysis Continuous Plankton Recorder (CPR) data, and particle tracking model simulations, was used to investigate processes involved cross‐shelf invasion. results showed that main source animals entering at depths greater than 600 m Faroe–Shetland Channel, where concentrations up 620 −3 are found...
Abstract Trawl data from Scottish research vessels dating January 1925 show that catches of the warm water pelagic species, anchovy ( Engraulis encrasicholus ) and sardine Sardina pilchardus ), increased suddenly after 1995. Most were observed in first quarter each year, with 1998 2003 having largest numbers, although few are available for last quarter. The authors believe these long‐term changes related to rising sea temperatures exact causal mechanism is not clear.
A significant correlation was observed between satellite derived chlorophyll a (Chl ) concentrations and the biomass of invasive comb jellyfish Mnemiopsis leidyi in southern Caspian Sea. By consuming herbivorous zooplankton, predatory ctenophore M. may have caused levels Chl to rise very high values ( mg There might also be several other factors concurrent with predation effects influencing this region, such as eutrophication climatic changes which play major roles nutrient, phytoplankton,...

The worldwide depletion of major fish stocks through intensive industrial fishing is thought to have profoundly altered the trophic structure marine ecosystems. Here we assess changes in English Channel ecosystem using a 90-year time-series (1920–2010) commercial fishery landings. Our analysis was based on estimates mean level (mTL) annual landings and Fishing-in-Balance index (FiB). Food webs been altered, as shown by significant decline mTL whilst increases FiB suggest increased effort...
The feeding habits of the European eel Anguilla anguilla (>300 mm total length, L T ) were compared in two lakes different environmental state: Lake Großer Vätersee (LGV), Germany (clear water, mesotrophic and submerged macrophytes), Vallum (LV), Denmark (turbid, eutrophic no macrophytes). density macrozoobenthos was higher LV (3500 individuals m −2 than LGV (1500 ). abundance small prey fishes (40–99 highest LV. In LV, A. fed on macrozoobenthos, particular, chironomid larvae. LGV, used...
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive data-rich area of the central North Sea using time-series datasets. The long-term trends show that abundances foraminiferans, coccolithophores, echinoderm larvae have risen over last few decades while bivalves pteropods declined. Despite good coverage data for study there is uncertainty quality this historical dataset; appears to been declining since mid 1990s but was no statistical...
In this paper we describe the construction of an online GIS database system, hosted by WorldFish, which stores bio-physical, ecological and socio-economic data for 'Coral Triangle Area' in South-east Asia Pacific. The has been built partnership with all six (Timor-Leste, Malaysia, Indonesia, Philippines, Solomon Islands Papua New Guinea) Coral countries, represents a valuable source information natural resource managers at regional scale. Its utility is demonstrated using biophysical data,...
Abstract Currently standard fish stock biomass estimates are based most directly on commercial catch-at-age data. The main contribution made by research-vessel trawl survey data to the assessment process is “tune” trends in and provide of incoming year-class strength. In this much information contained with (e.g. spatial detail) lost because first aggregated into numbers-at-age indices for given areas. Another problem that increasingly restrictive total allowable catches (TACs) imposed...

Marine protected areas (MPAs) are attaining increasing importance in the management of marine ecosystems. They effective for conservation tropical and subtropical (mainly coral rocky reefs), but it is debated whether they useful migratory fish stocks open temperate regions. World War II created a large area within which commercial fishing was prevented 6 years. Here we analyse scientific trawl data three important North Sea gadoids, collected between 1928 1958.

The yellowfin tuna ( Thunnus albacares: YFT) is a widely distributed, migratory species that supports valuable commercial fisheries. Landings of YFT are seasonally and spatially variable, reflecting changes in their availability accessibility to different fleets metiers which, turn, has implications for sustainable management. Understanding the dynamics behaviour how it affected by biological ecological factors therefore consequence fisheries management design. Archival pop-up satellite tags...
Long-term, seasonal and spatial patterns in spawning activity of Atlantic mackerel ( Scomber scombrus ) along the continental shelf west Europe were investigated. Stage I egg densities from all eight available international, triennial surveys (1977, 1980, 1983, 1986, 1989, 1992, 1995 1998) modelled using generalized additive models. The data showed that varied inter-annually. Total annual production peaked 1989 with minima 1983 1998. Further examination these trends (1977–1998) intensity has...
