    Notes: Lobster larvae were reared on a diet of unfed Artemia nauplii from either Great Salt Lake, Utah, USA (harvested in late 1981), or from the Artemia Reference Center, Ghent, Belgium. The two strains produced equivalent survival, development, and growth rates in the experimental animals. Success at metamorphosis for lobsters fed each strain was high despite observations in the literature that other larvae which experience a pronounced metamorphosis could show high mortalities when fed Utah Artemia. The results indicate that either temporal variability in nutritional value of Utah Artemia can alter growth patterns of predaceous lanae or that larval lobsters have appropriate metabolic mechanisms to overcome dietary deficiencies previously associated with Utah Artemia.

    Swedish Baltic Sea fisheries during 1868–1913: Spatio-temporal dynamics of catch and fishing effort (2007)

    Description: The current paper summarizes catch and effort data for Swedish fisheries in the Baltic Sea prior to the standardized recording of fish catches, evaluates spatial and temporal variations and gives interpretations of selected findings. Long-term datasets (1868–1913) of species having different environmental preferences (and of different origin) – marine, migratory and freshwater – are presented for several Swedish counties extending from the Bothnian Bay to the Bornholm Basin. Herring (Clupea harengus membras) was the most important commercial fish-based on landings and also on the amount of historical records available. In addition, herring landings have undoubtedly fluctuated the most. Other commercially important fish were cod (Gadus morhua), salmon and trout (Salmo spp.), flounder (Platichthys flesus), eel (Anguilla anguilla) and whitefish (Coregonus lavaretus). Different species exhibited different patterns of catch dynamics. In general, the 1880s and the 1890s can be characterized as ‘good fishing years’ for the Swedish Baltic fisheries: catches of herring and cod were high while fishing effort indices were relatively stable. Sprat was not represented in the catch data and may have been recorded as herring. For several species, regions and time periods, catch–effort relationship exhibited clear coupling. However, in several cases, insufficient or lack of effort-related information hampered data interpretations. In summary, the Swedish fisheries during the late 19th century generally exploited the same species as presently (including a dominance by clupeids), but the relative contributions of individual species have changed.

    Progressive changes in the Western English Channel foster a reorganization in the plankton food web (2015)

    Description: Highlights: • We unveil regional progressive climate modifications fostering the entire plankton food web. • Hydroclimate shifts have progressively impacted the seasonality of plankton. • The profound plankton reorganization warns on the replacement of local species by cosmopolitan ones. Abstract: Growing evidence has shown a profound modification of plankton communities of the North East Atlantic and adjacent seas over the past decades. This drastic change has been attributed to a modification of the environmental conditions that regulate the dynamics and the spatial distribution of ectothermic species in the ocean. Recently, several studies have highlighted modifications of the regional climate station L4 (50° 15.00′N, 4° 13.02′W) in the Western English Channel. We here focus on the modification of the plankton community by studying the long-term, annual and seasonal changes of five zooplankton groups and eight copepod genera. We detail the main composition and the phenology of the plankton communities during four climatic periods identified at the L4 station: 1988–1994, 1995–2000, 2001–2007 and 2008–2012. Our results show that long-term environmental changes underlined by Molinero et al. (2013) drive a profound restructuration of the plankton community modifying the phenology and the dominance of key planktonic groups including fish larvae. Consequently, the slow but deep modifications detected in the plankton community highlight a climate driven ecosystem shift in the Western English Channel.
