Enzyme polymorphism expressed in newly hatched cod larvae and genetic analysis of larvae exposed to hydrocarbons.
(ICES CM Documents;1980/F:22, Working paper, 1980)Cod eggs and larvae, at different stage of development, have been analyzed by starch gel electrophoresis. Four common enzymes (phosphoglucose isomerase, phosphoglucose mutase, isocitrate dehydrogenase and lactate ... -

Esterase variation in herring studied by isoelectric focusing
(ICES CM Documents;1997/AA:1, Working paper, 1997)Few suitable genetic characteristics for studying herring population structure are available, and the main aim of the study reported here has been to reveal traits which display useful genetic variations for application ... -
Estimated hatching date and growth history of Norwegian spring spawning herring (Clupea harengus L.) from otolith data of larvae of the 1990 yearclass
(ICES CM Documents;1991/H:14, Working paper, 1991)This study was performed on herring larvae of the 1990 yearclass of Norwegian spring spawners. The larvae were caught in May on the Norwegian shelf in the area from 64 °N - 69 °N. There was one size group of larvae with ... -
Estimates of stock size of cod, haddock, redfish and greenland halibut in the Barents Sea and the Svalbard area, autumn 1987
(ICES CM Documents;1988/G:44, Working paper, 1988)Combined acoustic and bottom trawl survey for cod and haddock were carried out in the Svalbard area together with an acoustic survey in the Barents Sea in autumn 1987. The abundance index in numbers of cod continued ... -
Estimates of stock size of northeast Arctic cod and haddock, "Sebastes mentella" and "Sebastes marinus" from survey data, winter 1988
(ICES CM Documents;1988/G:43, Working paper, 1988)An acoustic survey and a bottom trawl survey for cod and haddock were carried out in the Barents Sea during the winter 1988. The fish still had the westerly distribution established in the previous year, but the echo ... -
Estimating initial stomach content using stochastic simulation
(ICES CM Documents;1994/G:16, Working paper, 1994)The stomach evacuation model now in use when quantifying the predation from cod on Barents Sea capelin assumes that the evacuation rate is dependent on the stomach fullness after the last meal, which is not known in the ... -
Estimating the maturity ogive for northeast- arctic cod by a modified mesh assessment model
(ICES CM Documents;1983/G:33, Working paper, 1983) -
Estimation of predation mortalities on capelin using a cod - capelin model for the Barents Sea
(ICES CM Documents;1990/H:16, Working paper, 1990)The Barents Sea capelin stock collapsed during the period 1983-1986. One of the main factors causing the collapse was a rapid increase in consumption of capelin by cod. Based on measurements of stomach evacuation rates ... -
Evaluating bioencapsulation of florfenicol in rotifers (Brachionus plicatilis)
(Journal article; Peer reviewed, 2010-11-11)The rotifer Brachionus plicatilis is one of the most important live-feed organisms used in the larval culture of marine fish. Bioencapsulation of florfenicol in rotifers was investigated by delivering it directly to the ... -

Evaluating the effect of seismic surveys on fish — the efficacy of different exposure metrics to explain disturbance
(Journal article; Peer reviewed, 2013-06-05)To assess potential disturbance effects on fish from seismic air-gun surveys, we described several metrics to characterize the exposures from such surveys, including the number of emissions by area and time, and metrics ... -
Evaluation of emamectin benzoate and substance EX against salmon lice in sea-ranched Atlantic salmon smolts
(Journal article; Peer reviewed, 2015-04-08)Experimental releases of Atlantic salmon smolts treated with emamectin benzoate (EB) against salmon lice have previously been used to estimate the significance of salmon lice on the survival of migrating smolts. In recent ... -
