Notes and memoranda

A note about temperature observations off the southern coast of New England published in the bulletin of the United States Fish Commission. List of papers containing results of work done at the MBA but not published in the Journal. An important prosecution under the Sea Fisheries Regulation Act 1888, following the dumping of sludge on a trawling ground. Details of a trawl net which seems likely to prove useful to vessels for which a beam trawl is prohibited by its size. Notes and observations on: Gadus esmarkii (Nilss.),Phycis blennioides (Brunn), Sebastes norvegicus (Ascau), Crystallogobius Nilssonii (Dub. and Kor.), Arnoglossus laterna (Walb), Raia alba (Lacep.), young lobsters, a new British nemertine and the culture of sea fish.

Development and application of a high resolution liquid chromatographic method for the analysis of complex pigment distributions

Ternary and binary gradient systems have been developed for the high-performance liquid chromatographic analysis of complex pigment distributions typical of natural samples. Improved chromatographic resolution reveals significantly more pigment components in extracts from a sediment (Priest Pot, Cumbria, UK), a microbial mat (les Salines de la Trinital, South Catalonia, Spain) and a culture (C. phaeobacteroides) including novel bacteriochlorophyll derivatives. The methods developed are directly suited to LC–MS analysis and the automated acquisition of MS/MS data for pigments.
