[Age and growth characteristic of in the West Africa based on cuttlebones].

Common cuttlefish is mainly distributed in the eastern North Atlantic and the coastal waters of Africa, which is an important fishing target for trawl fisheries and the most important commercial species in the Atlantic sepia family. In this study, based on the cuttlefish samples collected from the west Africa coast in July-August 2015, we measured the outer morphological parameters of 283 cuttlebones. Combined with the age information of cuttlebones, we examined the growth characteristics of cuttlefish of different genders.
