The presence of heteromorphic B microchromosomes was detected in the karyotype of one female, exhibiting intra-individual variation of 0–3 Bs. The occurrence of heterochromatic polymorphisms, multiple NORs, and B chromosomes in C. figueiredoi are very infrequent events in marine fish. They are probably associated to the accentuated restructuring and genomic reduction suffered by this family. © 2010 Elsevier B.V. All rights reserved. 1. Introduction may possibly play an important role in speciation in marine environments, through the reproductive isolation of populations. Neotropical fish have demonstrated high karyotypic diversity, Despite the large number of living species, the appearance of including variations in diploid number, presence of sex chromosomes, cytologically different sex chromosomes in marine fish has been B chromosomes, natural triploids, heterochromatin polymorphism, as rare (Morescalchi et al., 1992). Nevertheless, simple and multiple sex well as nucleolus organizer region (NORs) polymorphism (Galetti, 1998). chromosome systems have been described in the Tetraodontiformes In the wide diversity of marine fish, the Order Tetraodontiformes (Sá-Gabriel & Molina, 2004).

The family Tetraodontidae has the lowest DNA elements present in some individuals or populations (Beukeboom, content per cell among the vertebrates (Neafsey & Palumbi, 2003; 1994).

Canthigaster capistratus (Lowe 1839), described from the Madeira Islands and previously considered to be a junior synonym of C. rostrata (Bloch, 1786), is revalidated and redescribed; it's known distribution extends from the Macaro- nesian Region to the Mediterranean. Canthigaster rostrata (Bloch, 1786), re- stricted to shallow-water northwestern Atlantic reefs, and C sanctaehelenae (Giinther, 1870), endemic to the mid-Atlantic islands of Ascension and St. Helena, also are diagnosed and redescribed. An identification key based on pigment pattern features is provided for all six Atlantic species of Canthigaster.

  • Reef Fisheries and Underwater Surveys Indicate Overfishing of a Brazilian Coastal Island
    Research Letters Natureza & Conservação 8(2):151-159, December 2010 Copyright© 2010 ABECO Handling Editor: Sergio R. Floeter Brazilian Journal of Nature Conservation doi: 10.4322/natcon.00802008 Reef Fisheries and Underwater Surveys Indicate Overfishing of a Brazilian Coastal Island Hudson Tercio Pinheiro*, Jean-Christophe Joyeux & Agnaldo Silva Martins Departamento de Oceanografia e Ecologia, Universidade Federal do Espírito Santo, Vitória, ES, Brasil Abstract The preoccupation about fishing effects on marine ecosystems has increased sharply over the last three decades. However, little is known about the impact of multi-gear artisanal and recreational fisheries on the structure of local reef fish communities in Brazil. Fishing activities around a Brazilian coastal island were monitored while reef fish density was censused during underwater surveys (UVC). The links between frequency of capture, intensity at which species are wished and UVC density were explored. Species were classified according to their frequency of capture as regular, occasional and rare, and classified according to the intensity at which they are wished (based on size and price), as highly targeted, average and non-targeted species. Ninety-seven species were caught by fishing, the majority of them being either rarely caught or non-targeted. Nineteen species were highly targeted but rarely caught. The highly targeted species showed extremely low density in the UVC. These results put in question the sustainability of the local fishing activities. The predominance of non-targeted species in the catches and in the reefs environment studied supports the expectation that these species will be more and more captured, thus collaborating to further change the structure of the reef community.

Seventy-six species were encountered in 252 censuses, with mean ± s.e.of99± 3 individuals and 15·7 ± 0·3 species 40 m−2 transect. The average fish biomass, calculated from length-class estimation, was 22·1kg40m−2 transect. The species contributing most to biomass were, in decreasing order, Melichthys niger, Cephalopholis fulva, Kyphosus spp., Holocentrus adscensionis, Sparisoma amplum, Sparisoma axillare, Acanthurus bahianus and Epinephelus adscensionis. Carnivorous fishes were the largest trophic group in terms of biomass, followed by omnivores and roving herbivores. The two predominant types of reef habitat, fringing reefs built by coralline algae and rocky reefs made of volcanic boulders, showed significant differences in the biomass and the abundance of the trophic guilds.

Optimum growth occurs at 20 - 28 °C in the presence of 3% NaCl. The Genome sequence of the novel isolate consisted of 4.224 Mb, 4,431 coding genes and G+C content of 44.5%. Genomic taxonomy analysis based on Average Amino Acid (AAI), Genome-to-Genome-Distance (GGDH) and phylogenetic reconstruction placed A621T (= CBAS 741T) into a new species of the genus Vibrio (Vibrio gaelis sp.
