Year-class strength regulation in plaice (, L.) on the Swedish west coast, In one area, Gullmar Bay (N 58 ° 19′ - W 11 ° 33′), 0-group plaice were sampled quantitatively with a drop trap at 0–0.7 m depth and densities between 0.2 and 3.8 ind./m. were recorded in early summer. In the other area, Laholm Bay (N 56 ° 30′ - W 12 ° 55′), 0-group plaice were sampled semi-quantit

, as a monitor of heavy metals in estuaries,for each element were: Zn, 19–437 .g g.; .g g.Cd, 0.07–4.8 .g g.; Hg, 0.02–0.23 .g g.. It is suggested that tissue analysis of . is one of the most useful biological techniques available in estuaries for pin-pointing aqueous (as opposed to sediment) metal contamination, and also for providing data s

Phytoplankton primary production and nutrients in the Oosterschelde (The Netherlands) during the pr of an ecosystem study..From comparisons of dissolved nutrient ratios with the nutrient requirements of phytoplankton, and of ambient nutrient concentrations with half-saturation constants for nutrient uptake by natural phytoplankton populations it was concluded that silicate was a limiting nutrient

Average annual growth and condition of mussels as a function of food source,in the western part near the North Sea, than in the central part of the estuary. No such difference was observed in 1986 and 1987..To predict the effects of the barrier on mussel culture, the condition of the mussels, which is an index of growth rate, is analysed and correlated with food sources for

Oosterschelde estuary (S.W. Netherlands): a self-sustaining ecosystem?,es high biotic diversity and high primary and secondary production. Before 1970 a major part of the water of the rivers Rhine and Meuse flowed into the Oosterschelde. The building of a permeable storm-surge barrier (1986) decreased the exchange between Oosterschelde and North Sea. The construction o
