  • Preliminary Results from Tag-Recapture Procedures Applied to Lemon Sharks, Negaprion Brevirostris (Poey 1868), at Los Roques Archipelago, Venezuela
    Preliminary Results from Tag-Recapture Procedures Applied to Lemon Sharks, Negaprion brevirostris (Poey 1868), at Los Roques Archipelago, Venezuela RAFAEL TAVARES Instituto Nacional de Investigaciones Agrícolas, Isla de Margarita, Estado Nueva Esparta,. Venezuela Centro para la Investigación de Tiburones, Caracas, Distrito Capital, Venezuela ABSTRACT During the period 2005 - 2008, 13 field surveys were conducted within the Archipelago Los Roques in order to examine the population structure and growth of juvenile lemon sharks, Negaprion brevirostris. Tag-recapture procedures were concentrated in the Sebastopol Lagoon (SL), an area previously identified as a nursery ground for this species. During the study, a total of 102 juvenile N. brevirostris (40.4 - 95.0 cm PCL) were captured within the SL; of these, 96 individuals were successfully tagged and released. Length composition was significantly different between sexes (Kruskal-Wallis; p < 0.001). Neonates (mean size: 46.1 cm PCL) were observed during June and July months, indicating that the birth season corresponds to this period. Mean growth rates were 24.2 cm year-1 for males and 21.9 cm/year for females. These estimates indicated that in the study area, juvenile N. brevirostris grow more rapidly than do juveniles in other populations of the same species distributed in the western Atlantic. KEY WORDS: Caribbean Sea, elasmobranchs, growth, nursery areas Resultados Preliminares Obtenidos de la Aplicación del Método de Marcaje y Recaptura en Tiburones Limón, Negaprion brevirostris (Poey 1868), en el Archipiélago Los Roques, Venezuela Durante el periodo 2005 - 2008, se realizaron 13 salidas de campo al Archipiélago Los Roques con el propósito de examinar la estructura de la población y el crecimiento de juveniles de tiburón limón, Negaprion brevirostris.

  • A Contribution to the History of Marine Turtles Exploitation in Venezuela
    A Contribution to the History of Marine Turtles Exploitation in Venezuela ANDRZEJ. ANTCZAK 1, JOAQUIN. BUITRAGO 2, MARIA. M. MACKOWIAK DE ANTCZAK 3, and HEDELVY. J. GUADA 4 1Unidad de Estudios Arqueológicos (IERU), Universidad Simón Bolívar, 89144 USB Módulo, Caracas 1086A, Venezuela, 2Estación de Investigaciones Marinas de Margarita, Fundación La Salle de Ciencias Naturales, Porlamar, Isla de Margarita, Venezuela, 3Departamento de Arquitectura, Diseño y Artes Plásticas y Unidad de Estudios Arqueológicos (IERU), Universidad Simón Bolívar, 89144 USB Módulo, Caracas 1086A, Venezuela, 4CICTMAR/WIDECAST, Apdo. 50.789, Caracas 1050-A, Venezuela, ABSTRACT The marine turtle populations in Venezuela have been systematically declining since the 16 th century, following the trend otherwise reported for other areas in the Caribbean. Turtle remains recovered in the pre-Hispanic archaeological sites are not as abundant as it might have been expected, even areas of recognised natural abundance of these animals such as the offshore islands. The reason of this scarcity is not clear and can be attributed to the recovery or preservation bias and/or to the operation of ancient taboos among other possible explanations. The ethnohistoric and other documentary sources testify that turtles were systematically exploited for eggs, meat, oil and carapace in all areas of their natural distribution, during the colonial (16 th – 18 th century) and republican (19 th century) times. The nesting beaches located on the offshore islands (Isla de Aves, Los Roques Archipelago and Margarita Island), and on the eastern continental coast, were especially targeted. The 20 th century brought the unprecedented intensification of the fishery and loss of natural habitats, principally the nesting beaches.

Samples were excavated in 7 Venezuelan islands and ascribed to distinct cultural groups on purely stylistic grounds (i.e. Valencioide, Ocumaroide, Dabajuroide and Unknown). Mean coercivity values were determined through a direct signal analyses (DSA) applied to isothermal remanent magnetization (IRM) acquisition curves. Logarithmic plots of these mean coercivities are the best quantitative means to classify diverse ceramics. The mean coercivity values seem to group the samples according to the manufacturing development. These values also seem to discriminate the samples provenance, indeed, this plot displays a good grouping of data for samples presumably manufactured by the same culture but excavated at different locations. Thermomagnetic cycles supply helpful information about original ceramic firing conditions. The irreversibility parameter (IP) for thermomagnetic curves (heating and cooling), serves as an indicator of the amount of organic matter burnt during original pottery firing.

  • LOS ROQUES FLATS FISHING VACATION Prices Starting at $2715 4 Night Package with 3 Days of Guided Fishing
    LOS ROQUES FLATS FISHING VACATION Prices starting at $2715 4 night package with 3 days of guided fishing BONEFISH MECCA IN THE SOUTHERN CARIBBEAN BASIN LOS ROQUES ARCHIPELAGO NATIONAL PARK • A beautiful reservoir of biodiversity and one of the world’s best bonefishing spots • Extensive flats for wading with skilled guides • Long season and consistent conditions • 50 island, 292 cays and extensive coral reefs covering 90,000 acres • Snorkeling, diving, sailing and beaches for non-anglers This complex of coral islands, flats, shallow water seagrass beds and red mangrove forests is one of the most pristine fly fishing environments in the Caribbean and the site of some of the best bonefishing anywhere. The dry climate, absence of large scale development, and protected national park status create an environment ideal for fly fishing almost year round, and the archipelago’s location at the far southern end of the Caribbean mean that tropical storms and cold fronts are not a major factor. The marine environment is rich enough to support 280 species of fish and 4 species of marine turtles. Los Roques Archipelago is located about 90 miles off the coast of Venezuela. The people are gracious hosts and getting there is as easy and as safe as visiting Mexico or Belize. World-class bonefish flats close to home Surprisingly, some veteran saltwater fly fishermen who’ve fished all three rate Los Roques higher than the Seychelle’s famed St. Francois atoll and Christmas Island’s flats. The sheer number of islands and cays, plus coral reefs, seagrass beds and mangroves provide excellent habitat for bonefish and a wealth of opportunities to approach them.

LA ICTIOFAUNA MARINA DE VENEZUELA: UNA APROXIMACIÓN ECOLÓGICA FERNANDO CERVIGÓN Fundación Museo del Mar, Boca de Río, Isla de Margarita, Venezuela [email protected] RESUMEN: A lo largo de las costas de Venezuela se pueden distinguir cuatro eco-regiones o ambientes ecológicos bien definidos por las características físico - químicas y bioquímicas (producción primaria) de sus aguas, así como su origen, a las cuales corresponden comunidades de peces que presentan claras y a veces acusadas diferencias entre si, en su composición específica, exclusiones o inclusiones, que no pueden atribuirse a barreras geográficas, sino a condiciones ambientales o ecológicas. Estos grandes ambientes ecológicos, dentro de los cuales pueden encontrarse subsistemas de características peculiares (lagunas hipersalinas por ejemplo) son los siguientes: (1) La plataforma atlántica, incluido el golfo de Paria, directamente influenciada por el drenaje de los grandes ríos suramericanos, principalmente el Orinoco y la corriente de Guayanas. (2) El área de fertilidad de la plataforma continental de la región nororiental del país, incluidas las islas de Margarita, Coche y Cubagua, sobre la cual actúan sucesivamente en el tiempo el fenómeno de surgencia costera (estación seca) y la influencia de los aportes del río Orinoco (estación lluviosa), además de otros factores de menor importancia (estuarios negativos por ejemplo). (3) Las áreas caracterizadas por la influencia directa, durante todo el año de las aguas oceánicas, en las que el fenómeno de surgencia costera no influye, o es muy débil y no existen drenajes de agua dulce significativos.
