Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
(Journal article; Peer reviewed, 2000-06-26)The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of the estuary and Gulf of St. ... -
‘Await’ in the pelagic: dynamic trade-off between reproduction and survival within a herring school splitting vertically during spawning
(Journal article; Peer reviewed, 2000-10-19)Spatio-temporal aspects of spawning behaviour were investigated in a single school of Norwegian spring-spawning herring Clupea harengus, and are explained by changes in the relative importance of reproduction, predation ... -
Recruitment of Atlantic cod stocks in relation to temperature and advection of copepod populations
(Journal article; Peer reviewed, 2000-11)The recruitment of Atlantic cod stocks shows different responses to temperature changes. Cod stocks inhabiting the lower temperature range show generally an increase in recruitment with increasing temperature, while cod ... -
A long-term perspective on the Chrysochromulina bloom on the Norwegian Skagerrak coast 1988: a catastrophe or an innocent incident?
(Journal article; Peer reviewed, 2000-11-22)The long-term effects of the 1988 algal bloom (Chrysochromulina polylepis Manton et Parke) along the Norwegian Skagerrak coast are evaluated and discussed on the basis of several monitoring programmes. Effects on individual ... -

Phylogenetic analysis of infectious salmon anaemia virus isolates from Norway, Canada and Scotland
(Journal article; Peer reviewed, 2001)The sequences of gene segments 2 and 8 from 10 different isolates of infectious salmon anaemia Virus (ISAV) sampled in Norway, Canada and Scotland between 1987 and 1999 were determined and compared. Pairwise comparisons ... -
Cod and climate variability in the Barents Sea
(Journal article; Peer reviewed, 2001)Interannual variability of temperature in the Kola section (Barents Sea) and the abundance as 0-group (age 5 mo) and recruits (age 3 yr), spawning stock biomass, and survival of Arcto-Norwegian cod in the Barents Sea were ... -

Designing and evaluating length–frequency surveys for trap fisheries with application to the southern rock lobster
(Journal article; Peer reviewed, 2001)A survey design for estimating the length distribution of harvested southern rock lobsters (Jasus edwardsii) was developed for the South Australian fishery. Experimental sampling was carried out by volunteer fishers in ... -
Herring tilt angles, measured through target tracking
(Report / Alaska Sea Grant College Program, Chapter, 2001)The target strength of herring in captivity was monitored experimentally at three frequencies (18, 38, and 120 kHz) over a period of 3 years using split-beam echo sounders. One of the fundamental parameters of a target ... -
Visual predation by the euphausiid Meganyctiphanes norvegica
(Journal article; Peer reviewed, 2001-01-05)Experiments showed that Meganyctiphanes norvegica are visual predators on copepods. Adult M. norvegica were offered a mixture of equal numbers of late stage Calanus spp. and Metridia longa in total darkness and at a light ... -
