Key fishing spots are associated with specific habitat features. The area around Estancia Piccinini, which borders Bahía Concordia, is a documented location for shark specimens. Rocky shorelines, crevices, and drop-offs provide structure that holds fish like the Patagonian Eelpout and other bottom species. The confluence of the bay with the main channel of the Ría Deseado likely creates productive edges and current breaks. Nearby locations such as Caleta Zar, Bahia Uruguay, and Caleta Tiburón (within the Ría Deseado system) also host similar species assemblages and can be considered as part of a broader fishing circuit.
