Growth of juvenile halibut (Hippoglossus hippoglossus L.) in captivity

Abstract

The growth and substrate preference of collected wild juvenile halibut under culture conditions were investigated. The size of the collected fish conformed well with year class data from earlier studies. Halibut growth in nature is slower than for i.e. cultured salmon up to the III-group. The present study showed, however, that halibut can grow much faster in culture than what is normal in nature. The substrate studies were contradictory in terms of growth and will have to be extended. The fish without substrate did, however, develope a dark coloration on the underside.
