The article is devoted to evaluation of the dimensional composition of mackerel in the South-East part of the Atlantic ocean. The study was carried out in Abidjan on the Ivory coast, specifically, at the Abidjan Autonomous port. The study objective was to establish the relationship between the total length and the weight of mackerel, as well as between the length of the mackerel body without the caudal fin and its weight. Weight of mackerel caught during commercial fishing in autonomous port of Abidjan was within 447.64-794.05 g, mean value being 591.08 g. Maximum length of mackerel made 41.5 cm, minimum is 35.2 cm (general length), mean value was 38.85 cm. Maximal fish length without caudal fin was 37.9 cm, minimal length - 31.7 cm, mean value made 35.13 cm. There has been stated linear dependence between general fish length and its weight. The research results will be used to further investigating the issue of industrial mackerel catches in the southeast Atlantic region.
