A comparison between abundance estimates of the Barents Sea capelin (Mallotus villosus Muller) at the larval, 0-group and 1-group stage, for the year classes 1981-1994

Three abundance estimates – larval abundance estimate (June surveys), a 0-group index (August surveys) and an acoustic estimate of 1-group (September surveys) – were compared for the year classes 1981–1994 of Barents Sea capelin ( Mallotus villosus Müller). There was a significant linear correlation...

Description
Summary:Three abundance estimates – larval abundance estimate (June surveys), a 0-group index (August surveys) and an acoustic estimate of 1-group (September surveys) – were compared for the year classes 1981–1994 of Barents Sea capelin ( Mallotus villosus Müller). There was a significant linear correlation (p=0.0001) between the 0-group index and the 1-group estimate, allowing for predictions to be made about year-class strength at the 1-group stage based on the 0-group indices. No correlation was found between the larval abundance estimate and the 0-group index, or between the abundance estimates at the larval and the 1-group stage.
