Variability in red snapper otolith microchemistry among Gulf of Mexico regions
Red snapper, Lutjanus campechanus, has been an economically important reef fish in the Gulf of Mexico (Gulf) for over 150 years and is currently overfished. Catch statistics and demographic differences have lead to the population being categorized into eastern and western substocks divided by the …

Real-Time PCR Combined with DNA Barcoding for the Authentication of Red Snapper (Lutjanus campechanus) Fillets
… monitoring coupled with complex supply chains. Red snapper (<em>Lutjanus campechanus</em>) is a highly valued and overfished species that is commonly substituted with other fish, such as tilapia, rockfish, and other snapper species. DNA barcoding is typically used by regulatory agencies to …

Determining the Trophic Role of Red Snapper (Lutjanus campechanus) in Mississippi State Waters Using Stomach Content and Stable Isotope Analysis
… trophic position and ecological role of red snapper <em>(Lutjanus campechanus</em>) in Mississippi state waters utilizing stable isotopes (δ<sup>13</sup>C and δ<sup>15</sup>N) and stomach content analysis. Stable isotope analysis of fish and their prey can provide information on …

Development of Genomic Resources for the Evaluation of Red Snapper, an Emerging Species Candidate for Marine Aquaculture and Stock Enhancement
<p>The northern red snapper (<em>Lutjanus campechanus</em>) is a highly targeted reef fish candidate for marine aquaculture and stock enhancement in the southern United States. This work aimed to develop genomic resources for the genetic management of aquaculture programs and to investigate …

Estimability of natural mortality within a statistical catch-at-age model: a framework and simulation study based on Gulf of Mexico red snapper
… algorithms from Gulf of Mexico red-snapper Lutjanus campechanus data. I investigated the influences of assumptions regarding model configuration of natural mortality and selectivity-at-age parameters by comparing multiple models. The results of this study are preliminary due to …

Fish Assemblage Structure, Distribution, and Trophic Ecology at Northwestern Gulf of Mexico Banks
… and 3) examine the trophic ecology of red snapper (Lutjanus campechanus), a common and highly prized reef-associated fish, at these features. Assemblage definition and relation to habitat was based upon baited underwater video surveys conducted across a range of depths and habitats. …

Reef fish demographics on Louisiana artificial reefs : the effects of reef size on biomass distribution and foraging dynamics
… of common reef-associated fishes, such as red snapper (Lutjanus campechanus). Spatial distribution of fish biomass was examined using a multifrequency hydroacoustic approach to examine the extent of the area of influence around the two habitats and to examine diel changes in distribution. …

Spatial Variation in Basal Resources and Trophic Position of Selected Fishes of the North-Central Gulf of Mexico
… exhibited varying degrees of habitat usage, with Red Drum being the most diverse, while Gafftopsail Catfish and Atlantic Sharpnose shark had more habitat specificity. This study presented evidence that freshwater inputs influenced the isotope values of reef fish species. d<sup>15</sup>N values of …

Fecundity and Survival of the Calanoid Copepod <i>Acartia tonsa</i> Fed <i>Isochrysis galeana</i> (Tahitian Strain) and <i>Chaetoceros mulleri</i>
<p>Historically, red snapper (Lutjanus campechanus) larviculture at the Gulf Coast Research Lab (GCRL) used 25 ppt artificial salt water and mixed, wild zooplankton composed primarily of Acartia tonsa, a calanoid copepod. Acartia tonsa was collected from the estuarine waters of Davis Bayou and …

Innovative molecular methods for fish species differentiation
… market samples were identified at species level. Snappers are a frequently studied fish family in food science because many mislabeled snapper products are found on the market due to their high morphological and genetic similarities. Especially, the “Red Snapper” (in Germany: L. malabaricus) is …

Genetic and morphometric variation of two focal snapper species (Lutjanus bohar and Lutjanus gibbus) in the Chagos Archipelago
… variation were investigated for two snapper species: two-spotted snapper (Lutjanus bohar) and humpback red snapper (Lutjanus gibbus), at four atolls (Diego Garcia, Egmont, Peros Banhos and Salomon) within the Chagos Archipelago in the Indian Ocean. This is an area which has some of …

The Effects of Minimum Size Limit Regulations On Exploited Fish Populations off the Atlantic Coast of the Southeastern United States
<p>The commercial snapper-grouper fishery off the Atlantic coast of the southeastern United States contains many exploited species that are managed with species-specific regulations, though primarily managed with minimum size limits. Minimum size limits vary by species and are intended to protect …
