Resumo: | Despite the social, ecologic and economic importance of the Brazilian northeast coast, knowledge regarding to biodiversity, assemblage structure and fish species distribution are still scarce, especially when related to environmental factors, which make difficult the implementation of ecosystem-based and sustainable management strategies. In this study, we describe the fish demersal assemblage along the continental shelf of the northeast Brazilian cost, specifically the ecological descriptors and the distribution and spatial abundance of the fish fauna. Sampling was conducted at 37 stations on board the R/V ANTEA, Between the latitudes 5°S-9°S. Fish species were described considering abundance (N° of individuals), biomass (weight) and frequency of occurrence. Community structure was investigated through ANOSIM and SIMPER analysis, while a DISTLM was performed to evaluate the influence of physical-chemical factors on the variability of fish data. Diversity was expressed as a series of indices and represented through maps. A total of 7.340 individuals (830 Kg), distributed in 24 orders, 49 families and 120 species, were collected. Haemulidae, Mullidae and Holocentridae were the most abundant families. The most frequent species were Hypanus marianae, Lutjanus synagris and Pseudupeneus maculatus. Higher abundance values were found in the central and south part of Pernambuco; however, considering biomass, higher values were also found in Rio Grande do Norte. Regarding to richness, higher values were found in Paraiba (PB) and south of Pernambuco (PE), while, considering diversity, high values were found along the entire study area. Comparatively with other regions in Brazil and around the world, the Brazilian northeast continental shelf can be described as an area of high fish species richness and diversity. DistLM analyses identified that depth, latitude and temperature explained 20% of the variation in the fish assemblage. Considering information found in this study, we consider the south of Pernambuco (8°30’S - 9°S), north of Rio Grande do North (5°S - 5°30’S) and the state of Paraiba (6°30’S - 8°S) as priority areas for the development of management plans and conservation of marine ecosystems. |

Neste estudo, descrevemos a assembléias de peixes demersais ao longo da plataforma continental do Nordeste do Brasil, considerando descritores ecológicos, distribuição e abundância da ictiofauna. Um total de 37 estações foram amostradas a bordo do ANTEA R/V, entre as latitudes 5°S- 9°S. A ictiofauna foi descrita considerando abundância (N° de indivíduos), biomassa (peso) e frequência de ocorrência. A estrutura da comunidade foi investigada através de análises ANOSIM e SIMPER. A análise DISTLM foi realizada para avaliar a influência de fatores físico-químicos na composição da comunidade de peixes, enquanto, a diversidade, foi expressa através de uma série de índices ecológicos representados através de mapas. No total, foram coletados 7.340 indivíduos (830 Kg), distribuídos em 24 ordens, 49 famílias e 120 espécies. As famílias mais abundantes foram Haemulidae, Mullidae e Holocentridae; enquanto as espécies Hypanus marianae, Lutjanus synagris e Pseudupeneus maculatus foram as mais frequentes. Maiores valores de abundância foram encontrados na parte central e sul de Pernambuco (PE); no entanto, considerando biomassa, valores mais elevados também foram encontrados no Rio Grande do Norte. Em relação à riqueza, valores elevados foram observados na Paraíba (PB) e no sul de Pernambuco (PE). Em relação à diversidade, valores elevados foram encontrados em toda a área de estudo. Em comparação com outras regiões do Brasil e do mundo, a plataforma do nordeste do Brasil pode ser descrita como uma área de elevada riqueza e diversidade de espécies. Com similaridade de 20%, as análises multivariadas exibiram quatro grupos principais (assembleias), apresentando diferenças significativas entre habitats. A análise DistLM identificou que as variáveis profundidade, latitude e temperatura explicaram 20% da variação encontrada nas assembleias de peixes. Considerando a informação encontrada neste estudo, podemos considerar o sul de Pernambuco (8°30 - 9°S), norte do Rio Grande do Norte (5° S - 5°30'S) e o estado da Paraíba (6° 30'S - 8°S) como áreas prioritárias para o desenvolvimento de planos de manejo e conservação dos ecossistemas marinhos.Submitted by Mario BC (mario@bc.ufrpe.br) on 2019-04-09T14:01:20Z No. of bitstreams: 1 Leandro Nole Eduardo.pdf: 2509775 bytes, checksum: 7fe73673ae11028db90e6d40eaa94cb5 (MD5)Made available in DSpace on 2019-04-09T14:01:20Z (GMT).
