Biological aspects of deep-water sharks Centroscymnus coelolepis and Centrophorus squamosus in Galician waters (north-western Spain)

Abstract

Biological observations on two deep-water shark species, Portuguese dogfish Centroscymnus coelolepis and leafscale gulper shark Centrophorus squamosus, were made for specimens caught by bottom trawl and longline between 500 and 1300 m depth off the continental slope of Galicia and Galician Bank (north-east Atlantic) in the years 1996–1998. This includes data on their bathymetric range, length distribution, size at first maturity, ovarian fecundity, uterine fecundity and the size at birth.
