Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil. Biota Neotropica. 19(1): e20170432. http://dx. Abstract:Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. The ichthyofauna consisted of 245 species (81 families, 32 orders and 2 classes). Among the species, 50 species were classified as constant, 38 accessory and 157 accidental. Still, 13.47% of the species were listed as endangered; 35.29% of the Chondrichthyes and 11.85% of the Actinopterygii (15.1% of the total species) belong to the endemic fauna of the Biogeographic Province of Argentina. The richness was directly related to the oceanographic features of the study area, which determined the southern boundary of occurrence of several tropical species and the northern boundary of occurrence for temperate species. This is the region with the highest abundance of fishery resources in Brazil. Lista de peixes demersais marinhos capturados pela pesca de parelha no Sul (RJ-SC) do BrasilResumo: Nas costas tropicais e subtropicais, sobre as plataformas continentais, os recursos pesqueiros demersais são abundantes e considerados uma parcela importante do ambiente marinho. Os recursos pesqueiros demersais marinhos são capturados por diversas modalidades de pesca, muitas vezes de forma insustentável, o que vem provocando o esgotamento de seus estoques. Com o objetivo de inventariar a ictiofauna demersal marinha da costa sudeste-sul do Brasil, assim como seu status de conservação e distribuição, foram analisadas a composição e frequência de peixes capturados em 117 cruzeiros de pesca entre 2005 e 2012 pela frota de arrasto de parelha sediada no Estado de São Paulo. A ictiofauna foi composta por 245 espécies (81 famílias, 32 ordens e 02 classes), sendo 50 consideradas como constantes, 38 acessórias e 157 acidentais; 13.47% apresentam algum grau de ameaça; 35.29% dos Chondrichthyes e 11.85% dos Actinopterygii (15.1% do total) pertencem à fauna endêmica da Província Zoogeográfica da Argentina. A riqueza observada está diretamente vinculada às características oceanográficas da área de estudo, sendo estas responsáveis pelo limite meridional de ocorrência de várias espécies tropicais e o limite setentrional de espécies de regiões temperadas. Esta é a região com maior abundância de recursos pesqueiros do Brasil...

Spatial distribution and shell utilization in three sympatric hermit crabs at non-consolidated sublittoral of estuarine-bay complex in São Vicente, São Paulo, Brazil Abstract.-The objective of the present study was to characterize the spatial distribution and shell utilization of three hermit crab species in the estuarine-bay complex of São Vicente, São Paulo State, Brazil. Monthly samples were done throughout two years, in the non-consolidated sub-littoral at the estuarine-bay complex. The environmental factors, such as temperature, salinity and depth, were measured every month. The three hermit crab species, Clibanarius vittatus, Loxopagurus loxochelis and Isocheles sawayai, were captured utilizing shells from six gastropods species; 92.7% of the hermit crabs utilized Stramonita haemastoma. The results suggest a strong correlation between hermit crabs spatial distribution and salinity, which was considered the main environmental factor limiting their distribution in the estuary. I. sawayai was the only species present in all transects sampled; C. vittatus was captured only in regions with low salinity and L. loxochelis occurred only in high salinity waters.

Abstract-The hooded slipper lobster (Scyllarides deceptor) and Brazilian slipper lobster (S. brasiliensis) are commonly caught by fishing fleets (with double-trawling and longline pots and traps) off the southeastern coast of Brazil.

The amount of Uruguayan lobster Metanephrops rubellus landed in the state of São Paulo has shown considerable annual variation, at first due to ups and downs in the fishing sector interest. However, biological factors may also be influencing, since little is known about the biology of M. rubellus, and most of the available literature on Nephropidae refer to the Norwegian lobster (Nephrops norvegicus), which is morphologically and behaviorally similar. The morphometric relations found characterize the relative growth of M. rubellus as positive allometric, except for Ct x Cc x Pt and Pa, which showed isometric growth. The length at first maturity (L50) and the length frequencies distribution indicate that fisheries are focusing preferably on the portion of population able to reproduce, saving the immature ones. Due to this and to the biological and behavioral similarity between N. norvegicus and M. rubellus, fishing closure or minimum size of capture are not recommended as fishery management tools. Instead, additional research is proposed in order to define the distribution area and density of population, to establish fishing exclusion areas, which function as reservoirs for replenishment of stocks. It is also essential monitoring the population dynamics parameters, in order to control fishing effort.
