2 Canadian Technical Report of Fisheries and Aquatic Sciences These reports contain scientific and technical information that represents an important contribution to existing knowledge but which for some reason may not be appropriate for primary scientific (i.e. Journal) publication. Technical Reports are directed primarily.towards a worldwide audience and have an international distribution. No restriction is placed on subject matter and the series reflects the broad interests and policies of the Department of Fisheries and Oceans, namely, fisheries management, technology and development, ocean sciences, and aquatic environments relevant to Canada. Technical Reports may be cited as full publications. The correct citation appears above the abstract of each report. Each report will be abstracted in Aquatic Sciences and Fisheries Abstracts and will be indexed annually in the Department's index to scientific and technical publications. Numbers in this series were issued as Technical Reports of the Fisheries Research Board of Canada. Numbers were issued as Department of the Environment, Fisheries and Marine Service, Research and Development Directorate Technical Reports. Numbers were issued as Department of Fisheries and the Environment, Fisheries and Marine Service Technical Reports. The current series name was changed with report number 925. Details on the availability of Technical Reports in hard copy may be obtained from the issuing establishment indicated on the front cover. Rapport technique canadien des sciences halieutiques et aquatiques Ces rapports contiennent des renseignements scientifiques et techniques qui constituent une contribution importante aux connaissances actuelles mais qui, pour une raison ou pour une autre, ne semblent pas appropries pour Ia publication dans un journal scientifique. II n'y a aucune restriction quant au sujet, de fait, Ia serie reflete Ia vaste gamme des interets et des politiques du Ministere des Peches et des Oceans, notamment gestion des peches, techniques et developpement, sciences oceaniques et environnements aquatiques, au Canada. Les Rapports techniques peuvent etre consideres comme des publications completes. Le titre exact paraitra au haut du resume de chaque rapport, qui sera pub lie dans Ia revue Aquatic Sciences and Fisheries Abstracts et qui figurera dans!'index annuel des publications scientifiques et techniques du Ministere. Les numeros de cette serie ont ete publies a titre de Rapports techniques de!'office des recherches sur les pecheries du Canada. Les numeros , a titre de Rapports techniques de Ia Direction generale de Ia recherche et du developpement, Service des peches et de Ia mer, ministere de I'Environnement. Les numeros ont ete publies a titre de Rapports techniques du Service des peches et de Ia mer, Ministere des Peches et de I 'Environnement. Le nom de Ia serie a ete modifie a partir du numero 925.
