abstract (from publication):
We report the occurrence of six specimens of white mullet Mugil curema Valenciennes, 1836 at Mar Chiquita coastal lagoon, Argentina (37°32’S-57°19’W). This is the southernmost record for the species in the western Atlantic and the first record from Argentinean waters. Morphometric and meristic characters of the six specimens are included.

results & discussion (extracts from publication):
Six specimens of Mugil curema were captured in Mar Chiquita coastal lagoon, Argentina (37º32’S-57º19’W) on 26 May and 16 June 2003. Mar Chiquita coastal lagoon is a temperate shallow estuary separated from the sea by a littoral line of dunes with an inlet joining it to the ocean. It is approximately 60 km2, with a maximum length of 25 km parallel to the sea. It is considered a World Reserve of Biosphere by the Coordination Council of the Man and Biosphere Program (MaB) of UNESCO. The capture of Mugil curema in Mar Chiquita lagoon apparently represents the southernmost record for the species in the western Atlantic and the first record from Argentinean waters.
Mugil curema commonly inhabits inshore waters and also enters estuarine regions where it feeds and grows (Menezes, 1983; García et al., 2001; Harrison, 2002). Adult M. curema migrate to the open sea to spawn (Cervigón et al., 1993). The capability to adapt to a wide range of salinities allows this species to penetrate in brackish and freshwater lagoons.
