A análise conjunta dos resultados de 311 exemplares de Mugil platanus capturados em diversos pontos da baía de Paranaguá indicou que na região a espécie apresenta um período reprodutivo entre maio e outubro, com picos em agosto e setembro, ocorrendo desova no período que compreende os meses de setembro, outubro e novembro. O IGS (índice gonadossomático), pôde ser utilizado como medida quantitativa do estádio de desenvolvimento gonadal. Provavelmente, as fêmeas maduras do início do período reprodutivo estejam de passagem pela área, desovando em outro local. ABSTRACT Analysis of 311 captured individuals of Mugil platanus from different points of the Paranaguá bay suggested that the species has a long spawning season (from between May and October) in this region. The spawn occurred between September and November, as IGS has indicated. Probably, ripe females from the beginning of the spawning season would be passing along this area to spawn in another place. RÉSUMÉ L’analise conjointe des résultats des 311 exemplaires de Mugil platanus capturés en plusieurs points du baie du Paranaguá, indique que dans la région l’espèce présente une période reproductive entre mai et octobre, surtout en aout et septembre.Des frais ont lieu dans la période comprise entre les mois de septembre, octobre et novembre.L’indicegonadossomatique peut être utilisé comme mesure quantitatif de l’estade de maturation gonatique. Probablement, les femelles mûris du début de le période reproductive sont de passage dans la region en frayant dans un autre lieu.

The Impact

Paranaguá bay is a complex estuary located in southern Brazil containing three protected areas listed by UNESCO. Historically, the estuary has been affected by urban, industrial, agricultural and harbor activities, and occasional accidents. Specifically, the explosion of the Chilean ship Vicuña in December 2004 spilled methanol and crude and fuel oils which affected both protected and non-protected areas. The present study sought to investigate the pollution threat to aquatic organisms in order to evaluate the potential effects of pollutants. One hundred and twenty adult fish Atherinella brasiliensis were collected from different sites within Paranaguá estuary, including the harbor and open ocean, during summer, autumn and winter of 2005. Among the biomarkers, the somatic index, chemical analysis of bile, biochemical, genetic and morphological parameters were considered. Chemical analysis of bile showed a continuous bioavailability of polycyclic aromatic hydrocarbons (PAHs) according to proximity to the harbor site. The histopathological findings have demonstrated aconsiderable incidence of severe pathologies in the liver and gills, corroborated by biochemical disturbances and genetic damage. These findings indicate that more studies are necessary to evaluate both water quality and fish health so as to permit a better analysis of the impact of pollution in Paranaguá estuary.

Karyotypic Diversity

In this study, five species of marine fishes from the Paranaguá Bay in the Brazilian coast were evaluated. Eucinostomus argenteus and Diapterus rhombeus (Gerreidae) presented 48 chromosomes, all of which more acrocentric (FN = 48); Strongylura timucu and S. marina (Belonidae) also presented 48 chromosomes, but with a higher karyotypic complexity than the Gerreidae, 10M+2SM+36A (FN = 60) and 4M+44A (FN = 52), respectively. The fifth species, Mugil curema (Mugilidae), different than the others, presented only 28 chromosomes 20M+4ST+4A (FN = 48). The species presented diversity in the karyotypic macro-structure, which should be relevant for the cytotaxonomy and the evolution of this group of the vertebrate.

Artificial substrates in and near ports and marinas commonly have many non-indigenous species and are the first stepping stone for the establishment of bioinvasors. Substrate movement influences fouling communities and so understanding of how species assemblages are related to specific substrate conditions is crucial as a management tool. Here we describe the species assemblage of the community after six months of development on granite plates in Paranaguá Bay. Species richness was similar in the two treatments, with 12 species on floating (constant depth) plates and 15 on stationary (variable depth) plates. However, species composition differed, with the community on floating plates being dominated by the native bivalve Mytella charruana (66.1 ± 5.5% cover) and that on stationary plates dominated by the barnacles Fistulobalanus citerosum (49.8 ± 3.5% cover) and the introduced Amphibalanus reticulatus (33.9 ± 3.7% cover). Other introduced species were Garveia franciscana, on one stationary plate, and Megabalanus coccopoma also on one stationary plate and not very abundant on half of the floating plates (< 2%). Thus, stationary plates were more susceptible to introduced species that may become very abundant, suggesting that this type of substrate should be a priority in management for bioinvasion control. We also hypothesize that the native bivalve M. charruana is the dominant competitor for space on floating substrates, thereby reducing the invasiveness of that type of substrate.

The aim of this work was to identify the introduced and cryptogenic species in encrusting and associated communities of hard substrates in Paranaguá Bay, Brazil, and to attempt to determine which of these species could negatively affect the local community to suggest management strategies for these species. At least four introduced species were found - a large number in comparison with other port surveys. These were the hydrozoan Garveia franciscana Torrey, 1902, the polychaete Polydora cornuta Bosc, 1902, the barnacles Amphibalanus reticulatus (Utinoni, 1967) and Striatobalanus amaryllis Darwin, 1854, all with potentially harmful impacts. Of the 33 cryptogenic species, four were also listed in the literature as causing negative effects. We propose the following management practices: periodic cleaning of all underwater structures, population monitoring of invasive species and potential substrates, an information database of potential sources of introduction.

This study describes the mangrove bird community of Paranaguá Bay in Paraná - South Brazil. Seasonal surveys were conducted during September 1997 to September 1998 at three sites in Paranaguá Bay. Frequencies and abundances of birds were registered in 200m transects and one hour point counts. A total of 81 bird species were observed in the three sampling sites. Most of the bird species in Paranaguá mangroves are fruits, seeds and arthropods consumers, and predators of flying insects. The most frequent and abundant species were Egretta caerulea, Ceryle torquata, Chloroceryle amazona, Pitangus sulphuratus, Turdus amaurochalinus and Parula pitiayumi. The bird community of these three sites is composed mainly by forest bird species. The mangroves of Paranaguá Bay shelter one of the richest avifauna of Brazilian mangroves. Differences between sampling sites could be related to the proximity of the Paranaguá city and human impacts in the areas. Only in the most disturbed site were observed Passer domesticus and large flocks of Coragyps atratus. This study contributed to the knowledge of mangrove communities, and could be an important basis to fluvial-marine conservation plans in Paraná- Brazil.
