Observations of growth and postspawning survival of lumpfish Cyclopterus lumpus from mark‐recapture studies

Growth and postspawning survival of lumpfish Cyclopterus lumpus are described by mark‐recapture experiments using juveniles in offshore areas in the north‐east Atlantic Ocean and spawning adults in coastal Norway and Iceland.

Description
Summary:Growth and postspawning survival of lumpfish Cyclopterus lumpus are described by mark‐recapture experiments using juveniles in offshore areas in the north‐east Atlantic Ocean and spawning adults in coastal Norway and Iceland. A female fish tagged as a juvenile and recaptured as an adult matured in a period of 18 months, providing the first observation on development in a wild C. lumpus . The von Bertalanffy growth function, fitted to data from recaptured fish, was used to estimate K and L ∞ and recaptured fish spawning after a year at liberty indicated a postspawning survival of c. 10% in Iceland.
