Dioxins in Baltic Herring and Sprat
Background, Aims and Scope. The concentration of chlorinated dibenzo-p-dioxins and dibenzofurans in many fish from the Baltic requires monitoring, since it approaches or exceeds the European Union threshold limit value of 4 pg TEQ/g wet weight of fish for human consumption. The concentrations, expressed in TEQs, are important for toxicology and regulations, but hide the concentrations of the in...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Sensory and Chemical Properties of Baltic Sprat (Sprattus sprattus balticus) and Baltic Herring (Clupea harengus membras) in Different Catching Seasons
Abstract. Baltic sprat (Sprattus sprattus balticus) and Baltic herring (Clupea harengus membras L) are two of the most caught fish species among the Estonian seacoast fishermen, and therefore it is important to understand catching season effects on sprat and herring sensory and nutritional quality. The aim of this study was to measure and compare sensory and chemical variability of Baltic sprat...
متن کاملDistribution and activity of pelagic fish – acoustic studies in the Baltic Sea
Fisheries agencies around the Baltic Sea use hydroacoustics to assess stock sizes of herring and sprat. These assessments rely on the assumption that the acoustic properties of Baltic clupeids are the same as North Sea herring. This may lead to biased results, as system-specific differences in salinity and fish fat content may influence acoustic target strength. The acoustic properties of the B...
متن کاملDepth-dependent nutritional condition of sprat Sprattus sprattus larvae in the central Bornholm Basin, Baltic Sea
Bimodal depth distribution patterns observed for sprat Sprattus sprattus larvae in previous field studies conducted in the deep basins of the Baltic Sea have led researchers to hypothesise that larval sprat condition was depth-dependent. We examined this hypothesis by measuring morphological, biochemical and otolith-based proxies for nutritional condition in sprat larvae collected in discrete 5...
