Resumen:
Characterization, identification of invertebrates and
monitoring of the benthic community at the Patagonian scallop fishing grounds
in the SW Atlantic Ocean have been continuous activities developed by
technicians, researchers and students working at the Benthos Laboratory
(INIDEP). Moreover, a very unusual (but undoubtedly helpful!) situation is
given by the fact that the baseline condition of this benthic community in the
year 1995 (before Fishery) is well-known and documented (Bremec and Lasta,
2002). In this benthic community, more than 150 invertebrate species have been
recorded until moment, being sessile or epibiotic near 50% of them. A
conspicuous assemblage of invertebrate species that characterizes this
community remained constant between 1995 and 2011 (Bremec et al., 2012). The
present contribution aims to characterize the benthic community in two
Patagonian Scallop Reproductive Reservations Areas (closed to commercial
fishing since 2009, Res.Nº5, CFP, 2009). Comparative benthic community samples
from the surrounding areas were also analyzed in order to compare taxa
composition and richness. The results here presented correspond to the
situation in October 2011.
