Some aspects of biology of the shorthorn sculpin Myoxocephalus scorpius (L.) in the Kola Bay, Barents Sea

The size-age structure, reproductive cycle and some morphological parameters (condition factor, gonad-somatic and lever-somatic indexes, the index of stomach fullness) of the shorthorn sculpin in the Kola Bay, Barents Sea have been studied. Equations on the "length – weight" dependance have been obtained, peculiarities of linear-weight growth have been revealed, periods of sexual maturity and spawning have been defined. Sex differences and seasonal dynamics of all characteristics have been analyzed. The results of this investigation indicate that the European sculpin is an important component of coastal ecosystems, as the entire life cycle is associated with this biotope. These studies have greatly expanded the understanding of biology of the species.
