(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1999)The aim of these recommendations is to standardize the methods used by different scientists for benthos surveys in order to increase the comparability of results for different areas. The results of ICES/HELCOM Quality ... -
Biological effects of contaminants: Quantification of metallothionein (MT) in fish liver tissue.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 1999)This document describes methods to analyse the protein metallothionein in fish tissues. Metallothionein is induced by and binds essential (Cu, Zn) and non-essential (Cd, Hg) metals and is used in monitoring programmes as ... -
Chlorophyll a: Determination by spectroscopic methods.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)Chlorophyll a is the principal pigment in plants. As a biomass indicator of aquatic microalgae which support food webs in the sea, it is probably the most frequently measured biochemical parameter in oceanography. This ... -
Biological effects of contaminants: Corophium sp. sediment bioassay and toxicity test.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)The method described here is a whole-sediment reworker bioassay using burrowing amphipods. This method description covers the use of Corophium spp., as this is the genus most commonly used in Europe, but the procedure can ... -
Biological effects of contaminants: Sediment bioassay using the polychaete Arenicola marina.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2001)The method described here is a whole-sediment reworker bioassay using the polychaete Arenicola marina, a direct deposit feeder that is widely distributed in European coastal waters and on the east coast of North America. ... -
Biological effects of contaminants: Radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA) techniques for the measurement of marine fish vitellogenins.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2002)This document describes immunochemical methods to quantify the egg-yolk precursor protein vitellogenin in fish plasma. Vitellogenin is normally produced by the liver of mature female fish in response to 17β-oestradiol (E2) ... -
Chemical measurements in the Baltic Sea: guidelines on quality assurance.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)This document provides an introduction to quality issues, in general, and quality assurance in Baltic marine monitoring laboratories, in particular. The guidelines are intended to assist laboratories in starting up and ... -
Biological effects of contaminants: measurement of lysosomal membrane stability.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)Lysosomes are ubiquitous cellular organelles that provide a waste disposal and macromolecular recycling system (autophagy) and also a membrane-bound compartment for intracellular digestion of food ingested by the cells. ... -
Recruitment studies: manual on precision and accuracy of tools.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)This manual is one of the results of the project Precision and Accuracy of Tools in Recruitment Studies (PARS), financed by the EU (FAIR-CT96–1371). The project PARS is concerned with improving the methodologies used in ... -
