Juveniles might be slightly spotted or flecked and have white undersides, which become mottled with grey or reddish spots as they mature. The survey was designed to generate an index of abundance for the exploitable population (≥ 81 cm), monitor changes in population trends and distribution, and provide an indication of incoming recruits. font-weight: 500; Halibut, any of various flatfishes (order Pleuronectiformes), especially the large and valuable Atlantic and Pacific halibuts of the genus Hippoglossus.
