Development stage and season influence in the metal content of small pelagic fish in the North-West Africa.

摘要: Abstract Marine organisms are exposed to great changes caused by man due discharges into the oceans, so study of marine pollution is value for each ecosystem. For this study, 963 specimens pelagic fish have been collected, which 345 Scomber colias, 294 Trachurus picturatus and 324 Sardina pilchardus, it was wanted development ontogeny in three species observing if there were variations their metallic content. The covered a total 2 years, from June 2016 May 2018. 16 samples studied month, during years sampling, samplings carried out Canary Islands Oceanographic Center Spanish Institute Oceanography (COC-IEO) markets Island Tenerife. concentration 11 anthropic metals determined sample using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) technique. Statistical studies with factors such as oceanographic season, level maturity gonads. S. colias that presented highest greater number metals. pilchardus presents higher Cu, Li Zn, warm season. These very character on coasts; This tends get closer coasts compared other two cause its these influence linked coast. immature had more than mature specimens.
