The two European anglerfish, Lophius budegassa and L. piscatorius are commercially important species in Europe, but our understanding of their basic biology is far from complete, hence the need to investigate its early life history through the analysis of otolith microstructure. Otolith microstructure analysis is an useful tool that provides information for determining important early life history associated with age and growth of juvenile fish, such as hatch dates and settlement dates, and reproductive and recruitment patterns.The otolith microstructure can also provide valuable information on the frequency of the first annual increments formation that can be corroborated by counts of daily increments. Age, growth and hatching patterns of both European anglerfish species are here estimated by using lapilli microstructure analysis. The otolith microstructure of juvenile anglerfish (< 30 cm) captured from bottom trawl surveys in southern Bay of Biscay (ICES Div. VIIIc, IXa) in ...
