Abstract
We provide the first list of marine fish from Anegada Bay, a coastal protected area in Buenos Aires Province. Fish records were obtained from gillnets and recreational fishery captures. Thirty seven species belonging to 29 families and 18 orders were identified. The most numerous order was Perciformes with eight families and 10 species. Odontesthes argentinensis, Micropogonias furnieri, Cynoscion guatucupa and Mustelus schmitti were verified in all sampling sites and the last two were the most represented either in the experimental fishing and recreational captures. Presence of Lagocephalus laevigatus extended the so far known range distribution of this fish species, representing the southernmost records in Argentinean coastal waters. The fish fauna composition from Anegada Bay could be considered as from a transitional zone.
Highlights
Anegada Bay (39°50’51” S to 40°43’08” S and 62°28’44” W to 62° 03’00” W) represents a faunistic reserve of multiple uses since 2001 and comprises an extensive area encompassing the southern part of Buenos Aires Province (Argentina), being its southern area considered as part of north Patagonian region (Figure 1)
A distinctive characteristic is the presence of San Blas channel which is a tidal inlet system connecting Anegada Bay with the outer sea
Pocitos (40°28’02” S, 62°22’36” W), placed on the south flank of San Blas channel in a more shallow and weaker energy environment, situated inside Anegada Bay; 2Punta Ramirez (40°31’17” S, 62°19’09” W) which is located at the mouth of a secondary tidal channel tributary of San Blas channel; 3- San Blas (40°31’48” S, 62°13’46” W) located on the north flank of San Blas channel, which is a high energy environment, near its opening to the sea
Summary
Anegada Bay (39°50’51” S to 40°43’08” S and 62°28’44” W to 62° 03’00” W) represents a faunistic reserve of multiple uses since 2001 and comprises an extensive area encompassing the southern part of Buenos Aires Province (Argentina), being its southern area considered as part of north Patagonian region (Figure 1). Anegada Bay is a shallow coastal system with different environments such as islands, inlets, marshes, tidal plains, pebble-and-gravel beaches and sand beaches. Three main areas were considered for fishing sampling: 1- Los
