“…Balneário Barra do Sul and Penha are located on the north central coast of the state of Santa Catarina, a region characterized by a mesothermal humid cli- mate, and rainfall and average annual temperature of 1,690 mm and 20.2ºC, respectively (ARAÚJO et al 2006b). Close to the coastal region, predominate the Coastal Water mass which has salinity below 34 and temperature ranging from 19 to 28ºC in winter and summer, respectively (SCHETTINI et al 1999). For the majority of the year, winds are predominantly from the northeast, changing periodically to southerly winds with advances of the polar frontal systems, which are more frequent and intense in winter (SCHETTINI et al 1999, ARAÚJO et al 2006b).…”

The fishing grounds are composed predominantly of sandy facies varying from very fine to medium sand (CORRÊA et al 1996, ABREU et al 2006, but considerably wide layers of fine sediments (silt and clay) also occur parallel to the coast (HORN FILHO 2003).…”

The present study analyzed qualitatively and quantitatively the temporal and spatial changes in the fish assemblages present in seabob shrimp distribution sites in two important fishing areas of the Santa Catarina coast. Monthly bottom trawls, conducted between March 2007 and February 2008 in Balneário Barra do Sul and Penha, yielded a total of 38,608 specimens belonging to 54 species, of which 35 occurred in both regions. The Sciaenidae was the most represented family in both number of species and abundance of individuals. The dominant species were Stellifer rastrifer (Jordan, 1889), S. brasiliensis (Schultz, 1945), Paralonchurus brasiliensis (Steindachner, 1875), Isopisthus parvipinnis (Cuvier, 1830), Trichiurus lepturus (Linnaeus, 1758), and Pellona harroweri (Fowler, 1917). The ichthyofaunal structure showed a spatiotemporal dependence with significant differences in March 2007 and January and February 2008 between Balneário Barra do Sul and Penha. The main differences were attributed to dominant species, which were responsible for significantly altering the abundance of the assemblages. The species richness was similar in both sites, whereas the diversity and equitability indices showed monthly fluctuation patterns that differed between Balneário Barra do Sul and Penha. The Shannon index differed in August, September and November 2007 and January and February 2008, with an H' ranging from 0.74 to 1.98 influenced by dominant species, whereas significant variations were observed for the Pielou index in November 2007 and February 2008. The Berger-Parker index demonstrated a clear dominance pattern where the monthly numeric contribution of a single species ranged from approximately 30 to 80%. Although the results showed differences between fishing grounds 25% of the time, we conclude that fish assemblies captured as accompanying fauna in artisanal seabob shrimp fisheries showed statistically similar characteristics for most of the year, although Balneário Barra do Sul and Penha are 35 km away from each other

“…These beaches are exposed, semi-exposed and sheltered to swells from the east and southeast and display medium-coarse grain sizes, high slopes, embayment between headlands, absence of redox layers and high hydraulic flux in the swash zone. The local tidal regime consists of microtides of discontinuous semidiurnal periods with mean amplitude of 0.8 m (Schettini et al 1999;Carvalho et al 1996), occasionally influenced by storms, which can raise the sea level ca. 1 m above astronomical tides (Carvalho et al 1996;Schettini et al 1999).…”

Most beaches are exposed and dominated by waves due to NS orientation of the coastline and NE-SW waves system or winds prevailing in the region (Klein and Menezes 2001;Barros et al 2001).…”

Protodrilus (Protodrilidae, Annelida) from the southern and southeastern Brazilian coasts

Protodrilus corderoi, Protodrilus ovarium n. sp. and Protodrilus pythonius n. sp. are reported from beaches in southern and southeastern Brazil and described combining live observations with light and electron scanning microscopy studies. Protodrilus corderoi is redescribed from new collections at the type locality, and a neotype for the species is assigned since the original type material no longer exists. New information on reproductive organs, segmental adhesive glands and unpigmented ciliary receptors as well as morphometrics is provided. Protodrilus ovarium n. sp. and P. pythonius n. sp. are formally described. Protodrilus ovarium n. sp. is diagnosed by the presence of separated lateral organs on segments 7-12, three spermioducts of segments 10-12 and salivary glands in segments 1-9. Protodrilus pythonius n. sp. is defined by the presence of separated lateral organs on segments 7-16, long pygidial lobes and body tapering toward the pygidium. The distribution of the different species in more or less spacious habitats seems to be correlated with their gross morphology. Protodrilus pythonius n. sp., with relatively long and wide body and long palps with ciliary bands, was collected in very coarse sandy sediments at a reflective sheltered beach. Conversely, P. corderoi and P. ovarium n. sp., both possessing more slender bodies with shorter, less ciliated palps, occurred in medium-coarse, well-sorted sediments in the more energetic swash zone of exposed intermediate-reflective beaches. The finding of P. pythonius and P. corderoi in nearby beaches corroborates other studies showing a higher morphological variability among species in different habitats within the same geographical area than among species in the same habitat in different geographical areas.

“…According to Schettini et al (1999), the waters of the Armação do Itapocoroy Bay are typically comprised of coastal waters (salinity lower than 34), with a seasonal temperature ranging from 19 • C to 28 • C. Both the salinity and the load of material in suspension are directly influenced by the Itajaí-açu River (Carvalho et al 1998, Resgalla Jr and, which has a plume of brackish water flowing northwards from the river mouth.…”

This paper presents information from different sampling surveys carried out along the Santa Catarina coast in order to outline the biogeographical characteristics of the zooplankton in this region and identify species or groups of species with potential use as bioindicators. Based on a checklist of species of the zooplankton community in the state, it was observed that, in the warmer months of the year, the fauna is similar to that of the states of Paraná and São Paulo (e.g. Creseis virgula f. virgula, Penilia avirostris; Acartia lilljeborgi and Oithona oswaldocruzi), while in the colder months there are coastal representatives of the fauna of Rio Grande do Sul (e.g. Acartia tonsa). However, the zooplankton consists predominantly of warm water species for most of the year, which is typical of Tropical Shelf Waters. Various species of zooplankton can be used as hydrological indicators, enabling a distinction to be made between coastal waters which are influenced by continental inputs (e.g. Paracalanus quasimodo and Parvocalanus crassirostris), common in the north of the state, and processes of upwelling (e.g. Podon intermedius) and the influence of the Subtropical Shelf Front (e.g. Pleopis polyphemoides), coming from the south. The different environments investigated present a zooplankton abundance that depends on the influence of continental inputs and the possibility of their retaining and contribution for the coastal enrichment, which varies seasonally.
