Preliminary observation on sexual maturity of black anglerfish (Lophius budegassa) in north-eastern Atlantic waters
The reproduction of black anglerfish (Lophius budegassa) was studied from samples collected during 5 years, from January 2006 to December 2010, in Celtic Sea, West and South of Ireland (ICES Div. VIIb-k) and Northern Spanish Atlantic waters (ICES Div. VIIIc-IXa). A total of 1167 specimens (4-99 cm)...

The sex ratio in both areas studied varied with length, and it was close to 1:1 (male:female), 1:1.22 (54.90% of females) in Div. VIIb-k, and 1:1.01 (50.30% of females) in Div. VIIIc-IXa.
