This work is based on the results of Soviet and American cruises into the Northwestern Atlantic Ocean. The data on dogfish biology for 1968-1978 are presented and summarized in it. The main object of this work is to provide the theoretical basis of measures for rational exploitation of dogfish stocks in the Northwestern Atlantic Ocean. To achieve this object the following problems have been solved: the areas, time and conditions of fishing aggregations formation have been specified, the absolute abundance and biomass, optimal fishing length and age have been estimated. The researches performed allow to tackle the problem of quantitative assessment of food items consumed by the shark and to specify the place of dogfish in the regional ecosystem. The active fishery of dogfish resumed in 1990s has made these researches urgent again. This requires the research materials, which allow verify and
