*:at mean ambient egg incubation temperatures of 5.75°C in May 1998 and 5.87°C in August 1991. Observed (obs) and adjusted (adj) abundance (n/m2) and daily production (n/m2/d) of different developmental stages inside the 80 m depth contour line, as well as resulting mortaliy rates (M) with and without correction for transport (corr) for May 1988 and August 1991.
