First estimates of age and growth of juvenile black anglerfish (Lophius budegassa), in the north-eastern Atlantic waters
Growth increments in the lapilli otoliths of the black anglerfish (Lophius budegassa) were used to investigate its early life history. Assuming that the primary increments are deposited daily, age and hatch dates were determined by counting these increments in the lapilli of 33 juvenile fish collect...
