Argentine anchovy (Engraulis anchoita) stock identification and incipient exploitation in southern Brazil

The Argentine anchovy (Engraulis anchoita) is an essential species in the pelagic ecosystem of the southwest Atlantic Ocean, and a potentially important fishery resource. Exploitation has recently started in southern Brazil, so it requires a better understanding of their structure and population dyn...
