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 …

Early life history of snapper (Chrysophrys auratus) in northern New Zealand
Snapper (Chrysophrys auratus) is a commercially-important fish in New Zealand and Australia. Variability in interannual recruitment is high in this species, which affects subsequent adult abundances, and therefore, an understanding of the factors that affect recruitment is critical to the …

A Population Genomic Study of Mutton Snapper (Lutjanus analis) Throughout Florida and the Caribbean
<p>The mutton snapper (<em>Lutjanus analis</em>) is a reef fish commonly found in tropical waters of the Western Atlantic Ocean. This species is sedentary at the juvenile and adult stages when spatial movements are limited to short migrations to join spawning aggregations. Dispersal, mediated by …

Real-Time PCR Combined with DNA Barcoding for the Authentication of Red Snapper (Lutjanus campechanus) Fillets
… 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 detect …

Age, Growth, and Reproduction of Vermilion Snapper (<i>Rhomboplites aurorubens</i>) in the North-Central Gulf of Mexico
<p>Vermilion Snapper is a commonly harvested species of reef fish in the northern Gulf of Mexico (GOM). It supports both a large commercial and popular recreational fishery, however knowledge of this fish’s life history is limited spatially. Non-linear curve fitting was used to estimate growth …

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 …

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 …

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 …

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 …

Do size differences of juvenile snapper (Pagrus auratus) in two regions of Shark Bay, Western Australia, reflect different environmental conditions
… study to management practices applied to the snapper fishery in Shark Bay are highlighted and discussed. In particular, a recommendation was made to modify the dates of the closed snapper-fishing season around spawning to July-August of each year, rather than mid-August to September, as is …

Population structure, biochemical adaptation and systematics in temperate marine fishes of the genera Arripis and Chrysophrys (Pisces: Perciformes)
… to provide information on the structure of snapper (C. Auratus) and western salmon (Arripis sp) populations in Australian waters. The results indicate that western salmon consist of a single breeding population extending across the southern Australian coastline, while at least five …

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 …

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 …

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. Four …

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. …

Influence of reef-associated predators on adjacent soft-sediment communities
… The role of reef-associated predators, the snapper (Pagrus auratus Sparidae) and rock lobster (Jasus edwardsii Palinuridae), was investigated using established marine reserves at each location. Consistent patterns were found in a few large-bodied fauna. The hermit crab Pagurus novizelandiae …

Non-heme iron C-H oxidation: tolerance of nitrogen-containing motifs with application to amino-acid and peptide oxidation
Direct oxidation of C-H bonds using non-heme iron catalysis has proven to be a highly useful transformation since its development in recent years. The ability to directly install oxygen into a hydrocarbon framework negates the need for pre-oxidized materials, and allows for quick and efficient …
