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 ... -
Abundance estimation of Northeast Atlantic mackerel based on tag recapture data - A useful tool for stock assessment?
(Journal article; Peer reviewed, 2010-10)In the present study we utilize tag recapture data to estimate year class abundance and spawning stock biomass of mackerel (Scomber scombrus L.) in the Northeast Atlantic for the period 1986–2008. On average 20,000 jigged ... -
Application of Coded Wire Tagging Technology in Pacific Herring to Investigate Stock Structure and Migration
(ICES CM documents, Working paper, 2001)Tagging of Pacific herring in British Columbia has a long history dating to the mid-1930s but uncertainty in tag recovery locations and low tag return rates limited the utility of these studies. Currently, a larger and ... -

Capture and handling of fish for electronic tagging - a review and a new non-intrusive capture method.
(ICES CM documents, Working paper, 1999)While tagging procedures are described in details the capture and handling of experimental fish prior to tagging is not given the same attention in most papers. However, traumas that originate from the capture and handling ... -

Detection of internally tagged fish with special application to the atlanto-scandian herring
(ICES CM Documents;1977/H:20, Working paper, 1977)The paper describes the operating principle and use of a new machine for detection and sorting of internally tagged fish. The machine has been used in the calculation of the Atlanto-Scandian herring stock size. Fixed ... -
Effect of size-selective mortality on growth of coastal cod (Gadus morhua L.) illustrated by tagging data and an individual-based growth and mortality model
(ICES CM Documents;1996/G:48, Working paper, 1996)Since 1983 more than one million reared cod juveniles have been tagged and released in different areas along the Norwegian coast. The goal of the programme is to evaluate the ecological and economical potential in sea ... -

Estimating tail-beat frequency using split-beam echosounders
(Journal article; Peer reviewed, 2009-02-04)Data from a standard split-beam echosounder are used to estimate tail-beat frequency within a dense herring (Clupea harengus L.) layer. The data were collected by lowering a horizontally projecting 38 kHz split-beam ... -
