“…In the 1960's, the trawl fishery activity increased due to the stimulus of the production perspectives of two species of coastal shrimps as pink shrimp (Farfantepenaeus spp.) and sea-bob shrimp (Xiphopenaeus kroyeri), and fishes from the Sciaenidae family, especially in wide areas of the continental shelf close to the regions of the southeastern and southern Brazil (Yesaki & Bager, 1975;Diegues, 1983;Valentini et al, 1991aValentini et al, , 1991bHaimovici, 1997).…”

ABSTRACT. The industrial double rig trawl fisheries are an important extractive activity in the southeastern and southern Brazil where near 300 vessels participate, targeting their catch to the sea-bob shrimp, pink shrimp and demersal fishes, such as flatfishes and monkfish. In order to advance in the fishery management, a general characterization of the trawl fleet operating in the area was done, identifying the patterns of nets used and the hydrodynamic performance of the nets observed by means of dynamic simulation. 194 vessels of Santa Catarina State and 130 vessels from other areas, mainly built in steel and wood, were identified. The largest size, tonnage, and capacity, correspond to those vessels working upon demersal and oceanic fishes. On the other hand, the most abundant vessels were those working upon pink shrimp (230 vessels). Regarding the nets, different patterns were identified according to the catch of target species; the smaller nets were used to catch shrimps (sea-bob and pink shrimp) and the largest were used to catch fishes. Mixed nets were also identified, characterized by similar dimensions of nets to catch fish but with mesh sizes of shrimp nets. From the simulations, different performance functions were adjusted according to each founded pattern; these functions will serve to calculate net's spread, their shape relationship, and the hydrodynamic drag forces. Key words: sea-bob shrimp, pink shrimp, demersal fishes, double rig trawl, dynamic simulation, Brazil.Pesquerías industriales de arrastre con tangones en el sudeste y sur de Brasil: caracterización de la flota, redes y simulación dinámica RESUMEN. Las pesquerías industriales de arrastre con tangones son una importante actividad extractiva en el sudeste y sur de Brasil donde participan cerca de 300 embarcaciones dirigiendo su captura a camarón siete barbas, camarón rosa, y peces demersales como peces planos y pejesapo. Para avanzar en el manejo pesquero, se realizó una caracterización general de la flota de arrastre que opera en el área, identificando los patrones de las redes usadas y el desempeño hidrodinámico de las redes observado mediante simulación dinámica. Se analizaron 194 embarcaciones del Estado de Santa Catarina y 130 embarcaciones de otras áreas, construidas principalmente de acero y madera. Las embarcaciones de mayor tamaño, tonelaje y capacidad correspondieron a aquellas que trabajan sobre peces demersales y peces oceánicos. La mayor cantidad de embarcaciones opera sobre camarón rosa (230 embarcaciones). Respecto a las redes, se identificaron diferentes patrones de acuerdo a las especies objetivo de captura; las redes más pequeñas fueron usadas para la captura de camarones (camarón siete barbas y camarón rosa) y las de mayor tamaño para la captura de peces. También se identificaron redes mixtas, caracterizadas por dimensiones similares a las redes para capturar peces pero con tamaño de malla de redes camaroneras. A partir de las simulaciones se ajustaron diferentes funciones de desempeño conforme a los patrones particula...

Simple ecological indicators were applied to landings and market data from the South Brazil Shelf Large Marine Ecosystem to investigate pressures on the ecosystem over time to contribute to fisheries and ocean assessments in data‐poor ecosystems. The indicators showed an increase in larger, long‐lived and piscivorous pelagic species landings as well as an increase in offshore fishing over the past few decades. Indicators based on market data showed a decrease of not only the target species but also of some long‐lived and large‐size coastal species, resulting in an increase of previously undesired fish species in the markets. Each of the selected indicators expressed part of the picture, while putting all together resulted in a more comprehensive view of the historical behaviour of this system.

“…Embora possua extrema importância comercial e também seja um dos principais predadores de macroinvertebrados bentônicos no estuário da Lagoa dos Patos (Valentini et al, 1991b;Bemvenuti, 1987), o camarão-rosa F. paulensis foi pouco abundante no Itajaí-Açu. Ele foi observado em quase todos os meses, com pico em junho de 2009, diferente do encontrado por Lopes (2008), que registrou maiores abundâncias da espécie no outono e mínimas na primavera em estuários de Ubatuba.…”

“…A espécie apresentou correlação negativa com a temperatura, ao contrário do observado por Branco & Verani (1998) na Lagoa da Conceição (Florianópolis -SC). A reprodução da espécie ocorre o ano todo (Valentini et al, 1991b) e a migração dos juvenis dos estuários para o oceano ocorre principalmente entre fevereiro e maio (Valentini et al, 1991b). Dessa forma, é provável que outros fatores possam ter minimizado a sua captura durante o verão, entre eles a dragagem, que teve início em dezembro de 2008, a elevada vazão do rio e ainda o pH que atingiu valores mínimos no período.…”

Estuaries are coastal water bodies with great economic and biological importance. The benthic organisms play a significant role in these environments as regulators or modifiers of physical, chemical and biological processes. This study aimed to evaluate the spatial and temporal distribution of the infralittoral decapods in the Itajaí-Açu estuary, investigating factors that influence their distribution and possible effects of a flood event on the benthic community. Six sampling points were established along the longitudinal gradient of the estuary. Monthly samples were taken with otter trawls between May 2008 and July 2010. The abundance and biomass of the crustaceans were analyzed using descriptive statistics. Variations in the physicochemical data of the water column, and its possible effects over the decapods, were also evaluated. The results showed that pH, salinity and dissolved oxygen are related to the penetration of the salt wedge, while temperature shows a seasonal pattern. The estuary showed a low richness (14 species), mainly in the two months after the flood of November 2008, and high dominance. It was possible to infer that many factors act on the estuary making it difficult to establish clear relationships between the biota and environmental variables in particular. There was an increase in abundance and biomass between February and July 2009, which suggests that the fauna was able to recover from the flood.
