Dockside grading project Canso Seafoods

In 1983 an extensive evaluation was conducted to determine the feasibility of a dockside grading program for trawler-caught fish delivered to Canso Seafoods Ltd. in Canso, Nova Scotia. Factors evaluated included: the effect of different handling methods utilized onboard; the effect of different onboard stowage methods; a comparison between the proposed Dept. of Fisheries and Oceans (DFO) dockside grading system and the H.B. Nickerson dockside grading system which had been in operation for over a year; a comparison between H.B.N. end of line inspections and the proposed DFO end of line grade standards, and the relationship between end of line evaluations and dockside grades; and the effect of other variables that impact on quality, such as parasites. Four offshore stern trawlers of a specific design were chosen, with an observer on each to collect 3 samples of cod, one of which was stowed in plastic boxes and the other two in pens. Tow data (area fished, date caught, tow length, tow weight, tow depth, fish temperature, water temperature, air temperature, gutting and handling procedures, washing effectiveness, icing and the lag from the moment the net of fish arrived on the deck until the last fish was iced in the hold) were also recorded.
