Empirical results on precision - effort relationships for acoustic surveys
(ICES CM Documents;1989/B:30, Working paper, 1989)Repeated echo integrator surveys using a rather dense survey grid were performed in areas where the effect of fish migration was assumed to be insignificant. Relative estimates of fish abundance representing different ... -
Endocrine and nutritional factors affecting the first food uptake by cod larvae
(ICES CM Documents;1982/F:17, Working paper, 1982) -
Engineering and fish reaction aspects of gillnetting - a review
(ICES CM Documents;1981/B:34, Working paper, 1981) -
Engineering and fish reaction aspects of longlining - A review
(ICES CM Documents;1981/B:35, Working paper, 1981) -
Enhancement of mussel culture by artificial upwelling of nutrient-rich deep water in fjords
(ICES CM documents, Working paper, 2004) -
Enhancing stock-recruitment models for North Sea cod by including climate and zooplankton
(ICES CM documents;2009/C:08, Working paper, 2009)The “recruitment problem” - trying to understand what regulates recruitment variability in marine fish populations - has been the number one issue in fisheries science since the early twentieth century. Intuitively, the ... -
Environmental effects of marine Norwegian fish farms
(ICES CM Documents;1985/F:37, Working paper, 1985)Sedimentation rates under fish farms may be very high, and high levels of fish stock may lead to harmful accumulation rates of the nutrient salt ammonia. The environmental effects of the organic load range from minor ... -
Environmental effects on ocean entry of Atlantic salmon (Salmo salar) smolt across its range of distribution
(ICES CM documents;2010/S:26, Working paper, 2010) -
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 ... -
Enzyme polymorphism of sprat from Norwegian waters - preliminary results
(ICES CM Documents;1981/H:65, Working paper, 1981) -
Episodic formation of intermediate water along the Greenland Sea Arctic Front
(ICES CM Documents;1995/Mini:6, Working paper, 1995)During CTD and plankton surveys in the Nordic Seas in November 1991 - 1994, a CTD section has been worked across the Arctic Front between the Lofoten and Greenland Basins. Along this front Isopycnic surfaces slope down ... -
Equivalent beam angles for several standard transducers
(ICES CM documents, Working paper, 1990)Nominal values for the equivalent beam angle are given for several transducers. These are the standard split-beam transducers designed for the SIMRAD EK500 scientific echo sounder, with operating frequencies of 38 and 120 ... -
Equivalent beam angles for several standard transducers
(ICES CM Documents;1990/B:21, Working paper, 1990)Nominal values for the equivalent beam angle are given for several transducers. These are the standard split-beam transducers designed for the SIMRAD EK500 scientific echo sounder, with operating frequencies of 38 and 120 ... -
Establishment of new wintering areas in herring co-occur with peaks in recruit to spawner ratio
(ICES CM documents;2009/H:11, Working paper, 2009)During late summer, Norwegian spring-spawning herring migrate to wintering areas, where they remain for about five months in dense aggregations. First-time spawning cohorts typically adopt the overwintering area of the ... -
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 capelin trawl efficiency by comparing the available fish with the actual catch.
(ICES CM Documents;1979/B:23, Working paper, 1979)Swept volume trawl efficiency for two different trawls were determined to be 28 and 60%, respectively by comparing the volume densities of capelin determined by echointegrator, with catch size and swept volume of the ... -
Estimates of mackerel stock composition in different areas and reasons as indicated by a cestone parasite
(ICES CM documents, Working paper, 1983)Recently collected data support earlier indications of the value of the plerocercus of the trypanorhynch oestone Grillotia angeli as a biological tag for estimating the size of the Western stock component in populations ... -
