Occurrence of tropical affinity fish in Galician waters, north-west Spain

Four new fish species have been recorded for the first time in the last few years in Galician waters: Physiculus dalwigkii, Neoscopelus microchir, Gaidropsarus granti and Pisodonophis semicinctus. The captures of Physiculus dalwigki, N. microchir and G. granti represent a new northern limit for their distribution in the north-east Atlantic, increasing their geographical range of distribution considerably while the capture of Pisodonophis semicinctus is the second record for the Atlantic European waters.

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

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.
