Evolution de l'activite-des flottilles françaises en Mer d'Irlande et en Mer Celtique ArchiMer
Charuau, Anatole; Morizur, Yvon; Rivoalen, Jean-jacques.
Since 1978, the habits of the french fishermen working with bottom trawl in the Irish Sea and in the Celtic Sea were altered (CHARUAU et M0RIZUR, 198l) under the pressure of the new mesh regulation.

International Program of Standardised Trawl Surveys ArchiMer
Mahe, Jean-claude.
The IPROSTS project had two main objective : - Completionn of research vessel surveys in the autumn of 1999 and 2000 in ICES areas VI, VII and VIII in order to provide abundance indices at age for the major commercial species exploited in these areas, - Standardisation of the methodology used in bottom trawl surveys. For completion of the first objective, the French Research institute IFREMER conducted surveys in the Celtic Sea and the Bay of Biscay on board the Research Vessel, Thalassa. The Marine Institute of Dublin conducted surveys in the Irish Sea and Celtic Sea on board the Research Vessel Celtic Voyager and in the Western area of Ireland on board two chartered commercial fishing vessels (Marliona and Shauna Ann). The Marine Laboratory of Aberdeen...
