Aspectos reprodutivos de Sphoeroides greeleyi (Gilbert), Pisces, Osteichthyes, Tetraodontidae, da gamboa do Baguaçu, Baia De Paranaguá, Paraná, Brasil Zoologia
Schultz,Yart Damasceno; Favaro,Luís Fernando; Spach,Henry Louis.
The present study analyses the reproductive aspects of Sphoeroides greeleyi (Gilbert, 1900), such as morphology and histochemistry of carbohydrates in the oogenesis phases, maturity scale, time and type of spawn, sexual rate and first ripened mature size for females. From the monthly captured animais (Nov 1998 to Nov 1999) the morphometric data (entire length and total weight) were extracted and the sex and the gonadal maturity were determined. Some ovaries were prepared for microscopic analysis that charac-terized six phases for the development of the ovarian folheies. Through the carbohydrates analysis the acid carbohydrates could be related to the oogenesis maintenance and the neutral carbohydrates to the beginning of embryonic development. A maturity...

Fish assemblages in a tidal flat BABT
Vendel,Ana Lúcia; Lopes,Sabine Granado; Santos,César; Spach,Henry Louis.
Studies were carried out on fish assemblages in a tidal flat. Samples were obtained monthly at low tide of the half moon in the tidal flat of Paranaguá Bay, Brazil, with two seine nets, one with a 1 mm mesh, 30 m in length and 3 m in height and another with a 10 mm mesh, 65 m in length and 2 m in height. A total of 8,890 fish were captured, comprising 24 families and 53 species. The most abundant species were Harengula clupeola and Atherinella brasiliensis, which represented 63.4% of the total, capture. A seasonal tendency was observed in the abundance of fishes, with less fishes being captured during winter and part of spring. The number of species showed a seasonal pattern, with the gradual decrease through winter and a marked increase in summer. The...

The objective of this work was to present an updated checklist of the currently known fishes in the Paranaguá Estuarine Complex (PEC) and provides comments on conservation status for the treated species. We used a large dataset derived from a pool of studies which have been conducted within there along the last 30 years. Each study was based on monthly samplings and conducted in several estuarine habitat; thus, the pool covers practically all estuarine habitats and takes into account the seasonal cycle in the system. The PEC ichthyofauna represents a mixture between that fauna typical from the tropical Brazilian coast and that with affinities of temperate Argentinean and Uruguayan zones. The PEC harbors a rich fish fauna of 213 species, inserted in the...

Godefroid,Rodrigo Santiago; Hofstaetter,Marion; Spach,Henry Louis.
A total of 6,575 larvae in the preflexion, flexion and post-flexion stages of 15 families, 26 genera and 29 species were captured in the surf zone of Pontal do Sul beach, Paraná, Brazil. Samples of the families Gerreidae and Scianidae predominated and larvae of Eucinostomus argenteus (Baird&Girard, 1854), Micropogonias furnieri (Desmarest, 1823), Eucinostomus gula (Cuvier, 1830), Menticirrhus ameri-canus (Linnaeus, 1758) and Anchoa tricolor (Agassiz, 1829) were the most dominant species. Greater abundance of larvae was observed during the summer, followed by winter and in a less extent during spring and autumn. The number of species was greater in the summer, and there were no significant differences in the rest of the seasons.

Ribeiro,Gisela Costa; Cattani,André Pereira; Hostim-Silva,Mauricio; Clezar,Leandro; Passos,Ana Carolina dos; Soeth,Marcelo; Cardoso,Olímpio Rafael; Spach,Henry Louis.
Abstract: This study aimed to present a checklist of marine fishes from coastal environments of the Island of Santa Catarina, including comments on the zoogeographic affinities, conservation status of each species, and functional groups. A total of 169 fish species belonging to 30 orders and 58 families were recorded. The most speciose families were Sciaenidae, Carangidae and, Engraulidae, representing 26,62% of the recorded species. Anchoa was the richest genus, followed by Sphoeroides and Cynoscion. Most of the species have their distribution limited to the western Atlantic, and two groups of fish were distinguished according to the species distributions: 1) species occurring in the Caribbean and in the Brazilian Province; and 2) Transatlantic species....

Morfologia e ultraestrutura de arcos branquiais de juvenis de Mugil platanus Günther (Pisces, Mugilidae) Zoologia
Fonseca Neto,José Claro da; Spach,Henry Louis.
Scanning electron microscopy revealed that the gill arch surface from juveniles of Mugil platanus Günther, 1880 is similar to that reported for others euryhaline teleosts. Two filament rows (about 41-49 filament per row) extend posteriorly, and two rows of rakers (about 42-46 rakers per row) extended anteriorly from each arch. Respiratory lamellae protrude along both sides of each filament (37/mm), from the base to the apex. The distribution, sizes and structure of various surface cells were also described. Except for the respiratory lamellae, the surface of whole gill arch is covered by a mosaic of pavement cells, which measure about 6,94X4,61µm and exhibit concentrically arranged surface ridges. The anterior pharyngeal surfaces of the raker of the first...

Occurrence of Larvae and Juveniles of Eucinostomus argenteus, Eucinostomus gula, Menticirrhus americanus, Menticirrhus littoralis, Umbrina coroides and Micropogonias furnieri at Pontal do Sul beach, Paraná BABT
Godefroid,Rodrigo Santiago; Santos,César; Hofstaetter,Marion; Spach,Henry Louis.
Despite its importance, most ichthyoplankton studies in the South-Southeastern coast of Brazil, have been accomplished on the continental shelf. Regarding the beach environment, recognized as a nursery, little is known about the ichthyoplankton. We analyzed 288 samples collected with a 18 by 2 m seine net, 1 mm mesh and a conical plankton net, with a mesh of 300 mum and a 60 cm mouth. Eucinostomus argenteus comprised 78 % of the larvae and juveniles caught in the samples. The occurrence of gerreids was strongly concentrated in the summer, while the Menticirrhus littoralis, Menticirrhus americanus and Umbrina coroides were present during all seasons. M.littoralis was most abundant during spring, while M. americanus and U. coroides dominated during winter....

Opsanus brasiliensis Rotundo, Spinelli & Zavalla-Camin, 2005 (Teleostei: Batrachoidiformes: Batrachoididae), sinônimo- júnior de Opsanus beta (Goode & Bean, 1880), com notas sobre a ocorrência da espécie na costa brasileira Biota Neotropica
Caires,Rodrigo Antunes; Pichler,Helen Audrey; Spach,Henry Louis; Ignácio,Juliana Martinhão.
Neste trabalho, dois exemplares de Opsanus coletados na costa do Paraná, e que representam os primeiros registros do gênero no sul do Brasil, foram identifcados como Opsanus beta (Goode & Bean, 1880). Uma comparação mais detalhada entre estes exemplares e a série-tipo de Opsanus brasiliensis Rotundo, Spinelli & Zavalla-Camin, 2005 (descrita originalmente do litoral de Santos, São Paulo), além de informações da literatura, indicou que Opsanus brasiliensis é sinônimo-júnior de Opsanus beta e que os representantes de Opsanus aqui encontrados são exóticos. É aqui levantada a possibilidade de que O. beta invadiu a costa brasileira através de água de lastro de navios que teriam zarpado das áreas naturais de ocorrência desta espécie.

Reprodução do peixe-rei, Atherinella brasiliensis (Quoy & Gaimard) (Atheriniformes, Atherinidae), em uma planície de maré adjacente à gamboa do Baguaçu, Baía de Paranaguá, Paraná, Brasil Zoologia
Favaro,Luís Fernando; Lopes,Sabine de C. G.; Spach,Henry Louis.
The present study investigated the reproductive biology of silverside, Atherinella brasiliensis (Quoy & Gaimard, 1825) in a tidal flat of Paranaguá Bay, littoral of Paraná State, Brazil. Fish were captured monthly from November 1998 to October 1999 by the mean of a seine-net. For each individual, total body length, total weight, sex, and gonadal weight were recorded. Gonadal development stages were also defined based on the histological examination of the ovaries and on the visual aspects of the testes. It was defined that the reproductive period of A. brasiliensis extends from June to December, based on he analyses of individual gonadosomatic index (GSI) values distribution in relation to the sampling periods, on the monthly variation of the GSI...

Structure and Dynamics of Fish Assemblages in a Tidal Creek Environment BABT
Vendel,Ana Lúcia; Spach,Henry Louis; Lopes,Sabine Granado; Santos,César.
Studies were carried out on structure and dynamics of fish assemblages in the Baguaçu tidal creek, Paranaguá Bay, Brazil. A total of 30,104 fish were captured, comprising 21 families and 47 species. Both in weight and in number, the species Anchoa parva prevailed. Monthly captures in number and weight were largest in the autumn and part of the winter. No seasonal tendency was observed in the indexes of community structure. The dendrogram produced by the classification of the samples separated the 12 months of collection into three groups, reflecting differences in the qualitative and quantitative occurrences of the most important taxa. Some ecological likeness, not only seasonal patterns of abundance, seemed evident in the seasonality of the groupings of...
