Los huevos, obtenidos de metamorphosis. The gametes were obtained from spontaneous desoves espontáneos, son esféricos, transparentes, pelágicos, spawning. Fertilized eggs are spherical, floating, transparent, lisos y poseen una sola gota lipídica. El diámetro total pelagic, with smooth chorion with one oil globule. The promedio fue de 0,89 ± 0,02 mm y el de la gota de aceite de average egg diameter was 0.89 ± 0.02 mm and the average oil 0,19 ± 0,01 mm. El estadio de mórula se alcanzó 2 h después de la fertilización, la blástula aparece a las 2 h: 40 min, la globule diameter was 0.19 ± 0.01 mm. The morula stage was gastrulación comenzó a las 3 h: 50 min y finalizó a las 6 h: 50 observed 2 h after fertilization, the blastula stage at 2 h: 40 min.

  • Ethnotaxonomical Considerations and Usage of Ichthyofauna in a Fishing
    Pinto et al. Journal of Ethnobiology and Ethnomedicine 2013, 9:17 http://www.ethnobiomed.com/content/9/1/17 JOURNAL OF ETHNOBIOLOGY AND ETHNOMEDICINE RESEARCH Open Access Ethnotaxonomical considerations and usage of ichthyofauna in a fishing community in Ceará State, Northeast Brazil Márcia Freire Pinto1*, José da Silva Mourão2 and Rômulo Romeu Nóbrega Alves2 Abstract Background: Artisanal fishery is one of the most important economic activities for human populations living in coastal areas. The traditional knowledge that fishermen have of fishes is of utmost importance for the establishment of conservation strategies for many species. This study aimed to analyse the knowledge of and utilization of fishes by the artisanal fishermen in a fishing community on the coast of Ceará State (Northeast Brazil). Methods: In 2011, a number of semi-structured interviews were performed with fishermen with more than 20 years of fishery experience. The interviews were about fisheries (collecting spots, artefacts, etc.) and fish use. The fishes cited by the fishermen were identified scientifically and ethnotaxonomically. Results: Considered masters of fishery, they cited 162 vernacular names of fishes, which corresponded to 290 different species, also including other animals such as dolphins, porpoises, whales and manatees. The criteria for the classification of the fishes were well known and utilised by the fishermen, and they were based on morphology, behaviour, habitat and the importance of commercial and fishing activities. Four hierarchical categories were identified in their classification system: kingdom, life-form, generic and specific. The fish nomenclature created by the fishermen was mostly composed of generic and monotypic names. The main uses of fish were for food and commercial purposes.

  • Phylogenetic and Morphologic Analyses of a Coastal Fish Reveals a Marine Biogeographic Break of Terrestrial Origin in the Southern Caribbean
    CORE Metadata, citation and similar papers at core.ac.uk Provided by PubMed Central Phylogenetic and Morphologic Analyses of a Coastal Fish Reveals a Marine Biogeographic Break of Terrestrial Origin in the Southern Caribbean Ricardo Betancur-R.1,2*¤, Arturo Acero P.2, Hermann Duque-Caro3, Scott R. Santos1 1 Department of Biological Sciences, Auburn University, Auburn, Alabama, United States of America, 2 Universidad Nacional de Colombia sede Caribe, CECIMAR/INVEMAR, Cerro Punta Betı´n, Santa Marta, Colombia, 3 Duque Caro y Cia. Ltda., Bogota´, Colombia Abstract Background: Marine allopatric speciation involves interplay between intrinsic organismal properties and extrinsic factors. However, the relative contribution of each depends on the taxon under study and its geographic context. Utilizing sea catfishes in the Cathorops mapale species group, this study tests the hypothesis that both reproductive strategies conferring limited dispersal opportunities and an apparent geomorphologic barrier in the Southern Caribbean have promoted speciation in this group from a little studied area of the world. Methodology/Principal Findings: Mitochondrial gene sequences were obtained from representatives of the Cathorops mapale species group across its distributional range from Colombia to Venezuela. Morphometric and meristic analyses were also done to assess morphologic variation. Along a ,2000 km transect, two major lineages, Cathorops sp. and C. mapale, were identified by levels of genetic differentiation, phylogenetic reconstructions, and morphological analyses. The lineages are separated by ,150 km at the Santa Marta Massif (SMM) in Colombia. The northward displacement of the SMM into the Caribbean in the early Pleistocene altered the geomorphology of the continental margin, ultimately disrupting the natural habitat of C.

In Brazil, coastal artisanal fishers usually depend upon reef fishes, such as grou- pers (Serranidae) and snappers (Lutjanidae), because these fish attain higher market values compared to other fishing resources. Most of these local and small-scale coastal fishers are located in high biodiver- sity areas, such as the Atlantic forest coastal remnants. Therefore, the management of artisanal reef fisheries faces a dilemma regarding the economic and ecological contexts: to conserve fish stocks (avoid their depletion) or to catch fish to fulfill immediate economic needs. Drawing from examples of different fisheries from northeastern to southern Brazilian coastal sites, we described this dilemma and provided man- agement suggestions, aiming to allow the development of sustainable artisanal fisheries.
