The information gathered in the fishing logbooks of shrimp trawlers operating in the Gulf of St. Lawrence during 1982 to 1991 inclusively is used to generate an atlas of this important fishing activity. The data are first checked for erroneous or incomplete records. The proportion of available valid information compared to the landings at the fish plants is calculated for each of the 5 fishing management units. Simple maps of weighted catch, of available effort and yields are then computed per year and per season; March-May and June– December. Maps of best significant annual yields, based on the available data, are then calculated. Summary maps joining the information of all years follow. They are maps of : total catch, mean catch and its standard deviation, for the whole fishing period or per season; mean monthly relative catch; weighted mean yield and its standard deviation over the whole fishing period or per season.
