“…Hiatt & Strasburg (1960) cited in Randall (1967) reported small fish and planktonic crustaceans as food items for fish of this genus. Trinectes paulistanus was little abundant in Jaguaribe beach, corroborating with Mendonça & Araújo (2002) that analyzed the temporal distribution of this species in Sepetiba Bay (RJ). It occurs in estuarine and marine environments (Figueiredo & Menezes 2000), being present in the northeastern coast (Araújo et al 2004).…”

Abstract:Resident fishes and their seasonal use of a surf zone were characterized and identified in the Jaguaribe beach, located on the Island of Itamaracá, state of Pernambuco, northeastern Brazil. Monthly towings (March 2006 to February 2007 with a beach seine net (20 m long, 1.5 m high, 5 mm mesh size) in different moon phases and periods of the day (day and night) were conducted. A total of 6,407 specimens, 35 families and 90 species were recorded. Seven species were considered as annual residents (Anchoa tricolor, Anchoviella lepidentostole, Bairdiella ronchus, Larimus breviceps, Lycengraulis grossidens, Polydactylus virginicus and Pomadasys corvinaeformis), three resident throughout the dry season (Conodon nobilis, Lile piquitinga and Menticirrhus americanus) and two resident species in the rainy period (Cathorops spixii and Nicholsina usta). Among these 12 species, concerning their life cycle, three of them (A. tricolor, C. spixii and L. piquitinga ) showed only adult individuals, while B. ronchus, M. americanus and N. usta were the only species represented exclusively by juvenile in both seasons. The surf zone of Jaguaribe beach presents a considerable ecological importance as it encompasses a great diversity of fishes, including species considered rare for this ecosystem, as well as species which are resident annually or seasonally. The distribution pattern of species found in this study shows that the ichthyofauna of the surf zone in Jaguaribe beach is rich, mainly dominated by small-sized individuals including juveniles of several species, with the presence of some species most commonly found in neighboring environments, such as seagrass beds, estuaries and reefs. As an integrated component of interconnected environments in coastal areas of Pernambuco, and owing to its function in the life cycle of coastal fishes, the surf zone of Jaguartibe beach presents an apparently common ecological pattern for tropical sandy beaches. . americanus e N. usta foram as únicas representadas exclusivamente por jovens nas duas estações. A zona de arrebentação da Praia de Jaguaribe possui considerável importância ecológica, uma vez que engloba uma grande diversidade de peixes, incluindo espécies consideradas raras para este ecossistema, bem como espécies que são residentes anual ou sazonalmente. O padrão de distribuição das espécies registradas neste estudo demonstra que a ictiofauna da zona de arrebentação da praia de Jaguaribe é rica, dominada principalmente por indivíduos de pequeno tamanho, incluindo a fase juvenil de várias espécies, com a presença de algumas encontradas comumente em ambientes adjacentes, como banco de fanerógamas, estuários e recifes. Como um componente de ambientes interconectados em áreas costeiras de Pernambuco e por sua função no ciclo de vida de peixes costeiros, a zona de arrebentação da praia de Jaguaribe apresenta um padrão ecológico aparentemente comum em praias arenosas tropicais. Palavras-chave: ictiofauna, Itamaracá, praias arenosas, peixes juvenis.

“…Flatfish are considered by BERENDZEN & DIMMICK (2002) to be monophyletic and very specialized; the group exhibits quite unique morphologic features (MENDONÇA & ARAUJO 2002). They belong in the widely distributed order Pleuronectiformes, which includes 570 species, 123 genera and 11 families (NELSON 1994).…”

“…They can be found in larger numbers in estuarine and marine environments, though they also occur in lacustrine regions (FIGUEIREDO & MENEZES 2000). Given the quality of their meat, flatfish are economically very important (MENDONÇA & ARAUJO 2002) and have considerable market potential.…”

ABSTRACT. The present study characterizes the oogenesis and the ovarian maturation scale, and determines the reproductive period, type of spawning, recruitment period, and population variations in the reproductive process of the flatfish Achirus lineatus (Linnaeus, 1758). Specimens were sampled on a monthly basis in the shallow near shore area of the Paranaguá Bay, state of Paraná, Brazil, from March 2006 to February 2007. The specimens collected were measured for morphometric data (total length and total weight) and their gonads were exposed for macroscopic evaluation. The gonads were subsequently removed, weighed and processed for microscopic analyses. Six phases of the ovarian follicle development were defined, as well as five ovarian development stages. Growth patterns differed between the sexes: negative allometry for females and positive allometry for males. Based on the seasonal assessments of the distribution of individual GSI values, the distribution of stages of gonadal development, individual body size, sex ratio, the ratio of juveniles to adults, and histological examination of the ovaries, reproduction was found to occur in the spring (spawning in batches), and recruitment in the autumn. These results show that A. lineatus is an estuarine-resident species that uses the study area for reproduction and recruitment, providing an argument in favor of the need to conserve the estuarine environment in order to preserve stocks. KEY WORDS. Oogenesis; maturity scale; reproductive period; type of spawning; sex ratio.

Revista Brasileira de Zoologia 21 (4): 857-864, dezembro 2004Citharichthys spilopterus Günther, 1862 e Symphurus tessellatus (Quoy & Gaimard, 1824) são duas das mais abundantes dentre as 14 espécies de linguados encontradas na Baía de Sepetiba (MENDONÇA & ARAÚJO 2002 (Quoy & Gaimard, 1824) in the Sepetiba Bay. The studied area was divided in three zones (inner, central e outer), where bottom trawls were performed during the day, from October 1998 to September 1999. Citharichthys spilopterus showed higher Indices of Relative Importance (IRI) for Mysidacea (0.3359) and Amphipoda (0.0805), while S. tessellatus showed the highest IRI for Amphipoda (0.7515) and Polychaeta (0.2586). The high percentage (67.61%) of empty guts in S. tessellatus suggests nocturnal feeding activity. Smaller sized individuals (TL < 115 mm) of C. spilopterus fed on Mysidacea in the three bay zones, while the larger sized (TL > 115 mm) fed on Polychaeta the inner zone, Gobiidae in the central and Decapoda in the outer. The smaller individuals (TL < 155 mm) of S. tessellatus fed mainly on Amphipoda while the largest (TL > 155 mm) fed on Polychaeta in the inner zone, and Amphipoda and Polychaeta in the outer zone. Citharichthys spilopterus, shows comparatively larger mouth and eye, and feed on organisms in the water column nearby, with a more specialized feeding habit, compared with S. tessellatus, which feed on organism on the substrate. Although the two species feed basically on Crustacea, they present low overlaping in the diet (0.197), and this is probably the trophic strategy developed to allow the coexistence of these two closely related species in the Bay. KEY WORDS. Bays, demersal fishes, diet, feeding habits.RESUMO. O objetivo deste estudo foi determinar as mudanças espaciais e ontogenéticas na dieta dos linguados Citharichthys spilopterus Günther, 1862 e Symphurus tessellatus (Quoy & Gaimard, 1824) na Baía de Sepetiba. A área de estudos foi dividida em três zonas (interna, central e externa), onde foram realizados arrastos de fundo diurnos no período entre outubro/1998 a setembro/1999. C. spilopterus apresentou os maiores Índices de Importância Relativa (IIR) para Mysidacea (0.3359) e Amphipoda (0.0805), enquanto S. tessellatus apresentou maiores IIR para Amphipoda (0.7515) e Polychaeta (0.2586). A elevada porcentagem (67,61%) de estômagos vazios em S. tessellatus sugere atividade alimentar noturna. Os espécimes de menor tamanho (CT < 115 mm) de C. spilopterus alimentaram-se de Mysidacea na três zonas e os maiores (CT > 115 mm) de Polychaeta na zona interna, Gobiidae na central e Decapoda na externa. Os menores espécimes (CT < 155 mm) de S. tessellatus alimentaram-se principalmente de Amphipoda e os maiores (CT > 155 mm) de Polychaeta na zona interna, e de Amphipoda e Polychaeta na zona externa. Citharichthys spilopterus apresentou maior tamanho de boca e olho, e se alimentou de organismos associados à coluna da água próxima, tendendo a uma dieta mais especialista quando comparado com S. tessellatus que se alimentou de organismos...
