“…A steady decline in recreational and commercial fishing harvests along the Texas coast from the mid-1980's through 2007 has increased interest in the health of wild populations and in larviculture to support stock enhancement (Froeschke et al, 2011). But, very little nutritional information beyond what is known for other larval fish is available for southern flounder larvae.…”

“…One such fish is the southern flounder (Paralichthys lethostigma), an important commercial and recreational food fish found along the mid-Atlantic Coast and the northern Gulf of Mexico. Improved understanding of its nutritional requirements is important because the species is a candidate for commercial aquaculture and stock-enhancement programs that seek to halt long term declines in wild populations (Miller et al, 2010;Froeschke et al, 2011).…”

“…Over the same period, recreational landings were about 50% lower in magnitude and were more evenly distributed among states between the Gulf of Mexico and South Atlantic basins (NMFS 4 ). However, recreational harvest may be a primary factor that is contributing to population declines in the Gulf of Mexico (Froeschke et al, 2011), and these declines have prompted a new stock enhancement program in Texas aimed at supplementing natural reproduction. Because no directed fishery exists for southern flounder in offshore habitats and exchange of individuals among states is not well understood, state management agencies assume unit stocks on the basis of state boundaries.…”

Abstract-Examination of otolith morphometric variation has been shown to provide improved descriptions of stock structure for several marine fish species. We examined spatial variation in otolith shape of southern flounder (Paralichthys lethostigma) to understand population structure at the following geographic levels: ocean basin (Atlantic and Gulf of Mexico); regional coastal waters (Texas, Florida) and (Georgia, South Carolina); and local coastal waters (North Carolina). To reduce variability, we considered only age-1 female fish. From digitized otolith images, we extracted descriptions for common shape indices and elliptical Fourier coefficients and found strong evidence for differences at the ocean basin scale, but only weak evidence for structure at either within-basin (i.e., among states) or within-state (local) spatial scales. Our finding of inferred stock structure differences between the ocean basins aligns with the geographic break in the distribution of this species-the absence of this species from the southern portion of Florida-as well as with recent genetic findings. Currently, state-level management of southern flounder in both areas does not account for any basin-wide population mixing and, therefore, by default, assumes a separate unit stock for each state, although our findings indicate that mixing could be extensive. Additional sources of information (e.g., genetics, life history traits) collected at appropriate spatial scales should be examined to confirm suspected levels of mixing and to determine suitable management strategies for the conservation of southern flounder stocks throughout their ranges.

“…Southern flounder, Paralichthys lethostigma, is an ecologically and commercially important large benthic flatfish inhabiting coastal waters of United States, which supports recreational and commercial fisheries (Froeschke et al, 2011;Renshaw et al, 2012). Farming southern flounder for food and recreational purposes started in the 1990s (Smith et al, 1999a,b;Jenkins and Smith, 1999), and now a stable spawning and seedling production technique has been established (Watanabe et al, 2006).…”

ABSTRACT. We investigated the genetic diversity of the southern flounder Paralichthys lethostigma. Microsatellite-enriched libraries were constructed and novel microsatellite markers were developed and applied for genetic detection of wild populations. Cross-species amplification was also conducted in five pleuronectiforme species. Of 45 randomly selected and sequenced clones, 43 contained a CA or GA repeat motif. Fourteen pairs of primers were designed to investigate the polymorphism and genetic structure of a wild population collected from North Carolina State coastal waters. Two loci were monomorphic and 12 loci were polymorphic. The number of alleles per polymorphic locus ranged from 2 to 16, with an average of 7.3, and the expected heterozygosity per locus ranged from 0.10 to 0.92, with an average of 0.58. Crossspecies amplification showed that most of the markers could successfully amplify Paralichthys olivaceus DNAs, few markers amplified in Verasper variegatus and Verasper moseri, and none of them could amplify Scophthatmus maximus and Cynoglossus semilaevis DNAs. The isolated polymorphic markers would be useful for the genetic breeding and assessment of genetic variation within the genus Paralichthys.
