A preliminary study of microstructure in otoliths of seacaught mackerel (Scomber scombrus L.) larvae
(ICES CM Documents;1990/H:4, Working paper, 1990)Mackerel larvae have been sampled during two cruises south of lrland, in May and June 1989 and preserved in ethanol. The microstructure of the otoliths (sagittae) from the mackerel larvae have been examined. There is a ... -
Age readings of Sebastes marinus otoliths: bias and precision between readers and otolith preparation methods
(ICES CM documents, Working paper, 2001)This study presents a comparative age reading on Sebastes marinus from the Icelandic shelf within an otolith exchange program between institutes in Germany, Iceland and Norway. Out of a series of 212 otolith pairs, ... -
Distinguishing between spring and autumn spawned herring from daily increments, a preliminary report
(ICES CM Documents;1988/H:15, Working paper, 1988)Otoliths from Norwegian Spring Spawning herring larvae, collected on a cruise in May 1985 and North Sea Autumn Spawned herring larvae, collected on a cruise in Desember 1987, were examined for daily increments. A greater ... -
Do capelin larvae deposit daily increments in their otoliths?
(ICES CM documents, Working paper, 2004)Analysis of increment formation in larval fish otoliths has provided valuable information about growth, transport and mortality processes of larvae in wild stocks, but the technique has not been widely used on capelin ... -
Growth patterns in otoliths as an indication of daily growth variations of larval herring (Clupea harengus) from an experimental ecosystem
(ICES CM Documents;1981/H:31, Working paper, 1981)Larval herring were released in a large outdoor basin four days after hatching and the mean growth in length and weight of the herring larvae and fry was monitored for 100 days. The food supply was estimated from weekly ... -
Growth rates and age distributions of capelin (Mallotus villosus) larvae in the Barents Sea investigated by otolith increment analysis
(ICES CM documents, Working paper, 2004)In order to investigate age distributions and growth rates, otoliths from capelin larvae collected from the Barents Sea during the summers 2001-2003 were analysed using otolith microstructure analysis. Stations were ... -
Primary growth increments in otoliths of cod larvae (Gadus morhua L.) of the Arcto-Norwegian cod stock
(ICES CM Documents;1981/G:54, Working paper, 1981)Primary growth increments are laid down in the otoliths of cod larvae living in a habitat where the light intensity is above the light threshold for visual feeding during 24 hours, and in which the larvae were observed to ... -
Primary growth rings in Blue Whiting otoliths
(ICES CM documents;1979/H:32, Working paper, 1979)To approach the problem of ageing blue whiting, acetat prints of the otoliths have been studied through a microscope. Primary growth rings have been counted, and provided that these are formed daily, the hatching time could ... -

Results of the workshop on comparative age reading on sprat from ICES Div. IIIa
(ICES CM Documents;1994/H:13, Working paper, 1994)The paper presents results from comparative age reading on sprat otoliths from various areas within Div. IlIa. Readers from fishery laboratories in Denmark, Norway and Sweden participated in the workshop. The reproducibility ...
