Assessment of contaminant concentrations in sediments, fish and mussels sampled from the North Atlantic and European regional seas within the ICON project ArchiMer
Robinson, Craig D.; Webster, Lynda; Martinez-gomez, Concepcion; Burgeot, Thierry; Gubbins, Matthew J.; Thain, John E.; Vethaak, A. Dick; Mcintosh, Alistair D.; Hylland, Ketil.
Understanding the status of contaminants in the marine environment is a requirement of European Union Directives and the Regional Seas Conventions, so that measures to reduce pollution can be identified and their efficacy assessed. The international ICON workshop (Hylland et al., in this issue) was developed in order to test an integrated approach to assessing both contaminant concentrations and their effects. This paper describes and assesses the concentrations of trace metals, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls in sediments, mussels, and fish collected from estuarine, coastal and offshore waters from Iceland to the Mediterranean Sea. For organic contaminants, concentrations progressively increased from Iceland, to the...

Direct assessment of anchovy by the PELGAS04 acoustic survey ArchiMer
Masse, Jacques; Beillois, Pierre; Duhamel, Erwan.
An acoustic survey was carried out in the bay of Biscay from April 27th to May 25th on board the French research vessel Thalassa. The objective of PELGAS04 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly sardine and anchovy but had to be considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability".

Integrated indicator framework and methodology for monitoring and assessment of hazardous substances and their effects in the marine environment ArchiMer
Vethaak, A. Dick; Davies, Ian M.; Thain, John E.; Gubbins, Matthew J.; Martinez-gomez, Concepcion; Robinson, Craig D.; Moffat, Colin F.; Burgeot, Thierry; Maes, Thomas; Wosniok, Werner; Giltrap, Michelle; Lang, Thomas; Hylland, Ketil.
Many maritime countries in Europe have implemented marine environmental monitoring programmes which include the measurement of chemical contaminants and related biological effects. How best to integrate data obtained in these two types of monitoring into meaningful assessments has been the subject of recent efforts by the International Council for Exploration of the Sea (ICES) Expert Groups. Work within these groups has concentrated on defining a core set of chemical and biological endpoints that can be used across maritime areas, defining confounding factors, supporting parameters and protocols for measurement. The framework comprised markers for concentrations of, exposure to and effects from, contaminants. Most importantly, assessment criteria for...

Sardine series in PELGAS surveys : PELGAS 2000 to 2005 ArchiMer
Masse, Jacques; Duhamel, Erwan; Delaunay, Damien.
Survey data from 2000 to 2004 were used to analyse whether sardine show a preferential distribution in relation to bottom depth and/or latitude. For this analysis, four strata were considered; North or South of latitude 46°N (separating VIIIa and VIIIb) and bottom depths deeper or shallower than 110m. Sardine length distributions are plotted as the proportion of small (< 18.5 cm) or big (larger than 18.5 cm) fish on the samples over the years. This division was chosen to take into account the bimodal structure of sardine length distributions (usually with a "valley" at 18.5 cm fish length). Small fish (mainly 1 year old) are generally found close to the coast and preferentially in the southern part. The year 2003 is different to the others but this year...

The French anchovy fishery ArchiMer
Duhamel, Erwan; Biseau, Alain; Masse, Jacques; Villalobos, Hector.
The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (<10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour.

The French sardine fishery ArchiMer
Duhamel, Erwan.
This approach of the French sardine fishery shows mainly that pelagic trawlers are targeting less and less sardine, year after year. In an assessment approach, it would be necessary to define an estimation of fishing effort, but it will be very difficult. We are able to compt the number of fishing days, but not the time of fishing (or number of shoots for example for purse seiners) or time of searching schools. So, accessibility and catchability could be certainly more accurate than the fishing effort for assesment purposes.
