A program for estimation of number and survival of a population, given a series of tag release/recapture data.
(ICES CM Documents;1982/G:7, Working paper, 1982)A computer program for convenient storage of tag release/recapture data is given. The program provides a facility to combine yearclasses if release/recapture are split into yearclasses. One estimate of number and three ... -

Birth-date selection in early life stages of plaice Pleuronectes platessa in the eastern Irish Sea (British Isles)
(Journal article; Peer reviewed, 2007-09-13)For species with extended spawning seasons, short periods of beneficial conditions often lead to disproportionate survival of sub-sets of the offspring. This has been demonstrated for freshwater fish and for marine pelagic ... -
Effects of pre-release acclimatization period on salmon return rates
(ICES CM Documents;1995/M:13, Working paper, 1995)42.000 1+smolts of Atlantic salmon were size graded into two size groups and released during three weeks in spring 1993; one group of small and one of large smolts on each of the four release days. Approximately 25% of ... -
Fangst av leppefisk: Ruse gir like god overlevelse som teine
(Havforskningsnytt;Nr. 1 - 2012, Working paper, 2012)Leppefisk er viktig i oppdrettsnæringens lakselusebekjempelse. I 2010 ble det fanget ca. 10 millioner leppefisk til dette formålet. Det blir hevdet at teiner gir fisk av bedre kvalitet enn ruser, og enkelte oppdrettsselskaper ... -
Growth and survival studies of halibut (Hippoglossus hippoglossus L.) from hatching to beyond metamorphosis carried out in mesocosms
(ICES CM Documents;1986/F:16, Working paper, 1986)To each of five floating plastic bags 1500 halibut larvae were transferred from the hatchery one day after hatching. The plastic bags had a volume of 11.5 m3, a total depth of 5.5 m and they were moored to floating ... -
Mass-production of cod fry (Gadus morhua L.) in a large basin in western Norway - a new approach
(ICES CM Documents;1984/F:16, Working paper, 1984)In February 1984, the fresh water in a small lake was replaced by seawater pumped from 40 m depth. Four-day old cod larvae were transferred on 11 and 26 April into this seawater basin, which was 5 m above sea level with ... -
Maternal influences on offspring size variation and viability in wild European lobster Homarus gammarus
(Working paper, 2010-02-11)In many marine species, large females tend to produce more robust offspring than small females. However, knowledge on maternal influences in decapod crustaceans is limited. This is unfortunate since many decapod populations ... -
Production of juvenile flatfish species in different sized mesocosms
(ICES CM Documents;1985/F:65, Working paper, 1985)Mesocosm studies with larvae of halibut (Hippoglossus hippoglossus), sole (Solea solea) and turbot (Scophthalmus maximus) was carried out at Austevoll Aquaculture Station and at Flødevigen Biological Station in 1985. ... -
Prøvedyrking av stort kamskjell i mellomkultur - 1995-1996
(Fisken og havet, Research report, 1996)The production of King scallop (Pecten maximus) in culture may involve three steps; artificial spat production in hatchery, intermediate culture for production of seed and production of cornrnercial sized scallops in ... -
Recruitment Variability in North Atlantic Cod and Match-Mismatch Dynamics
(Journal article; Peer reviewed, 2011-03-07)Background Fisheries exploitation, habitat destruction, and climate are important drivers of variability in recruitment success. Understanding variability in recruitment can reveal mechanisms behind widespread decline in ... -

Studies on the chemical structure of cod egg chorion
(ICES CM Documents;1984/F:10, Working paper, 1984)The chemical structure of the cod egg chorion has been investigated in preparations of chorion obtained after decompression rupture of cod eggs. The chorion was purified free of non-integral components by sucrose gradient ... -
Survival of mackerel and saithe escaping through sorting grids in purse seines
(ICES CM Documents;1996/B:24, Working paper, 1996)Technology for efficient size-selection of mackerel and saithe in purse seines has been developed. A critical constraint for application of the technology is the survival of escaping fish. We have conducted a series of ... -

Vekst og overlevelse for larver og yngel av atlantiske torskebestander, komparative studier i posesystemer
(Fisken og havet, Research report, 1995)To evaluate genetic differences in survival and growth potential under similar environmental and feeding conditions, cod (Gadus morhua L.) larvae from different stocks (Northeast Arctic cod, coastal cod from western ...
