Feeding biomechanics of juvenile red snapper (Lutjanus campechanus) from the northwestern Gulf of Mexico.

Feeding biomechanics of juvenile red snapper (Lutjanus

INTRODUCTION Ecomorphological studies are predicated on identifying patterns among morphology, behavioral performance and ecology (Wainwright, 1994), and have been utilized to test a variety of hypotheses concerning the relationships between feeding performance and foraging ecology among teleosts (e.g. Clifton and Motta, 1988; Wainwright, 1996). Ecomorphological studies are also useful in exami...

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

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; ...

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...

Artificial reef placement: a red snapper, Lutjanus campechanus, ecosystem and fuzzy rulebased model

This study on reef placement involves two aspects: (1) the development of a bioenergetics model for red snapper, Lutjanus campechanus (Poey), in Gulf of Mexico waters off the coast of Alabama, where significant numbers of artificial reefs are thought to exist, and (2) a fuzzy rough set model by which parameters determined from the bioenergetics model can provide a decision tool for optimally sp...
