Biological effects of contaminants: Quantification of δ-aminolevulinic acid dehydratase (ALA-D) activity in fish blood.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)This document describes a colorimetric method to quantify the enzyme δ-aminolevulinic acid dehydratase (ALA-D) in fish blood. ALA-D is an enzyme in the heme synthesis pathway. The activity of the enzyme is inhibited by ... -
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. ... -
Biological effects of contaminants: use of liver pathology of the European flatfish dab (Limanda limanda L.) and flounder (Platichthys flesus L.) for monitoring.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2004)publication provides quality assurance guidelines for the use of liver pathology of flatfish in biological effects of contaminants monitoring programmes. Information on the sampling procedures, including macroscopic ... -
Review of analytical methods for determining metabolites of polycyclic aromatic compounds (PACs) in fish bile.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2005)In fish, metabolites of polycyclic aromatic compounds (PACs) in gall bladder bile can be used as biomarkers for recent environmental exposure to PACs. These metabolites in the bile result from hepatic biotransformation ... -
Biological effects of contaminants: measurement of scope for growth in mussels.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2006)Scope for growth (SFG) is a method of assessing the whole-animal physiological response to sublethal stress induced by pollutants. It has been applied widely in small- and large-scale pollution monitoring programmes in ... -
Biological effects of contaminants: the use of embryo aberrations in amphipod crustaceans for measuring effects of environmental stressors.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2008)This report describes the methodology for assessing the proportions and different types of embryo aberrations in both sediment‐dwelling and nektonic amphipods. Determination of malformed embryos is a sensitive method of ... -
Guidelines for the study of the epibenthos of subtidal environments.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2009)These Guidelines for the Study of the Epibenthos of Subtidal Environments document a range of sampling gears and procedures for epibenthos studies that meet a variety of needs. The importance of adopting consistent sampling ... -
Pitfalls and guidelines for “recycling” models for ecosystem-based fisheries management: evaluating model suitability for forage fish fisheries.
(2014)Ecosystem models have been developed for many marine systems to provide guidance on fisheries management strategies that protect key ecological functions. These models are commonly “recycled”, i.e. applied to new questions ... -
Calibration of acoustic instruments.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2015)Acoustic sampling has long been a standard survey tool for estimating the abundance and distribution of fish, zooplankton, and their seabed habitat (Kimura, 1929; Sund, 1935; Holliday, 1972a; Nielson et al., 1980). ... -
Handbook of geo-statistics in R for fisheries and marine ecology.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2017)Fisheries surveys to estimate the abundance of populations have become a pillar in providing fishery-independent data to determine the status of fish stocks and monitor ecosystems. Since the early 1990s, ... -
Manual of recommended practices for modelling physical – biological interactions during fish early life.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2009)The objectives of this manual of recommended practices(MRP) are to summarize appropriate methods for modelling physical–biological interactions during the early life of fish, to recommend modelli ... -
Acoustic target classification.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2018)Data are collected from a variety of acoustic systems in many countries to address a range of ecosystem monitoring and stock management objectives. A key step in the analysis of fisheries acoustics ... -
IEC/ISO Bow-tie analysis of marine legislation: a case study of the Marine Strategy Framework Directive.
(International Council for the Exploration of the Sea (ICES), Copenhagen, Denmark, 2018)Marine planning and coastal zone management require an understanding of the policy context (Cormier et al., 2015) that addresses ecosystem, cultural, social, economic, and legal aspects (Barnard and Elliott, 2015). ... -
ICES Guidelines for XBT data. (Compiled January 2000; revised August 2001; April 2006)
(International Council for the Exploration of the Sea (ICES), Copehagen, Denmark, 2006)The Expendable Bathythermograph (XBT) has been used by oceanographers for many years to obtain information on the temperature structure of the ocean to depths of up to 1500 meters. The XBT probe is typically launched ... -
