The spatial distribution of shortfin squids in the area between the Gulf Stream and Nova Scotian shelf is analysed based on the data collected during the joint Soviet-Canadian cruise aboard the RTM "Belogorsk" in 1979. A detailed analysis of the hydrological data is made indicating a close correlation between the squid distribution and the structure of water masses in the area. Relationships between the squid distribution and oxygen minimum and temperature profile, as well as between the squid abundance and proportion (per cent) of the North Atlantic Central Water in the slope water masses are established. A method of estimating the young shortfin squid abundance in the given area based on T-S analysis of water masses is proposed. The hypothesis is suggested that larval squids are transported from the continental slope to the northern boundary of the Gulf Stream.
