In 1925 a Fisheries Technological Program was begun in temporary quarters on the Halifax waterfront to provide scientific research and technical assistance to improve the handling, processing and quality of fisheries products in Atlantic Canada. From that date through to 1979 (with a move to permanent buildings next door) studies on fish processing (smoking, drying, fresh and frozen storage, protein stability, marine oils, enzymatic and bacterial spoilage and grading systems among others) were conducted and the results transferred to industry, government and international agencies with a high degree of success and benefits. After it was apparent that product quality was affected by the condition of fish prior to harvest, more effort was devoted to physiological studies of live fish. In the 1960s studies concerning live lobster storage and latterly technical support for developing aquaculture ventures, i.e. health studies, nutritional requirements, environmental needs and physical structures, were added. Following the termination of the technological program in 1979 the buildings were used to accommodate elements of the Fisheries Resource Branch until theY'could be re-Iocated in 1997. This retrospective traces the reasons for programs and offers brief sketches of the studies and their application. En 1925, un programme d'etudes technologiques sur les peches voyait Ie jour dans des locaux provisoires situes sur Ie front de mer d'Halifax (il a em menage dans un edifice permanent tout pres des locaux originaux par la suite). Le but du programme etait d'assurer une aide scientifique et technique afin d'ameliorer la manutention, la transformation, et la qualite des produits de la peche au Canada Atlantique. De 1925 jusqu'en 1979, Ie programme n'a jamais cesse ses activites. On y a etudie la transformation du poisson (fumage, sechage, entreposage de produits frais ou congeles, stabilite des protei.nes, huiles marines, deterioration des produits provoquee par des enzymes ou des bacteries et systemes de classement, entre autres choses), et on a transmis les resultats de ces etudes a I'industrie, aux gouvemements et aux agences internationales qui en ont retire de nombreux avantages; Lorsqu'il est devenu evident que la qualite du produit est egalcment influencec par I'etat du poisson avant la recolte, on a commence a consacrer davantage d'efforts aux etudes physiologiques du poisson vivant. Au cours des annees 1960, on a ajoute des etudes sur les conditions d'enti-eposage du homard vivant et, plus recemment,on s'est interesse aux besoins de l'industrie aquacole, a savoir l'etat de sante des poissons d'elevage, leurs besoins nutritifs, leurs besoins lies au milieu et les structures physiques. Quand le programme d'etudes technologiques a pris fin en 1979, les edifices ont ete utilises par certaines composantes de la Direction des ressources halieutiques jusqu 'a ce qu'elles amenagent dans d'autres locaux en 1997. Voici une retrospective de la raison d'etre des programmes,des etudes qui ont ete menees et de leurs applications.
