Experimental Population Dynamics of Amyloodiniumocellatum in the Spotted Seatrout, Cynoscionnebulosus, and the Red Snapper, Lutjanus campechanus

Spatial and Dietary Overlap Creates Potential for Competition between Red Snapper (Lutjanus campechanus) and Vermilion snapper (Rhomboplites aurorubens).

Understanding the complex nature of direct and indirect species interactions is a critical precursor to successful resource management. In the northern Gulf of Mexico fisheries ecosystem, red snapper (Lutjanus campechanus) and vermilion snapper (Rhomboplites aurorubens) are two commercially harvested species within a larger reef fish complex. These two species share similar habitats and diets; ...

Estimation of hook selectivity of red snapper (Lutjanus campechanus) and vermilion snapper (Rhomboplites aurorubens) from fishery independent surveys of natural reefs of the northern Gulf of Mexico

Population structure of Lutjanus purpureus (Lutjanidae - Perciformes) on the Brazilian coast: further existence evidence of a single species of red snapper in the western Atlantic.

The present study focus on the mitochondrial control region to investigate phylogeographic patterns and population structure in Lutjanus purpureus, and to evaluate the genetic similarity between L. purpureus and L. campechanus. For the initial analysis, 810 base pairs sequence from control region were obtained from 239 specimens of L. purpureus collected from four localities off the Brazilian c...

Regional variation in mercury and stable isotopes of red snapper (Lutjanus campechanus) in the northern Gulf of Mexico, USA.

The presence of total mercury (Hg) in fish tissue and the potential associated health risks has become a global concern in marine ecosystems. Few studies have examined basin-scale variation in Hg accumulation in marine ecosystems, and determining if Hg concentrations in fish tissue vary across marine ecosystems is a key monitoring question. The present study evaluated Hg concentrations in red s...

Temporal and Spatial Variability in Juvenile Red Snapper Otolith Elemental Signatures in the Northern Gulf of Mexico

—We examined otolith chemistry of age-0 red snapper Lutjanus campechanus in U.S. waters of the northern Gulf of Mexico (GOM) to determine if otolith elemental signatures could be employed as natural tags to estimate postsettlement population connectivity. Fish (n 1⁄4 755) belonging to five successive yearclasses (1996–2000) were sampled from three GOM regions. Solution-based analysis of otolith...
