Dashes indicate lack of fishing effort in area and time period. In general, bycatch rates increased from west to east. Bycatch rates of Black-footed Albatrosses tended to increase during the season. Sea surface temperature and net soak time did not significantly affect bycatch rates of Black-footed Albatrosses. Spatial and temporal variation in bycatch rates of Black-footed Albatrosses in the 1990 Japanese squid driftnet fishery.
Dashes indicate lack of fishing effort in area and time period.
For latitudes 35 N and 45 N, adjusted bycatch rates tended to increase from west to east, whereas for latitude 40 N they increased from east to west. The general tendency was for bycatch rates to increase during the season. Bycatch rate was negatively related to sea surface temperature. A 1-degree increase in sea surface temperature resulted in an estimated decrease in bycatch rate of 0.003. Bycatch rate and net soak time were positively related.
