“…A systematic review by Rivas () suggested that this species is generally found from Tampico, Tamaulipas, Mexico, southward to Belize; hence, this species has been generally thought to have the narrowest range of any snook species (Kubicek et al. ). We observed two specimens from Lower Laguna Madre and a third specimen in Aransas Bay, suggesting occasional incursions of this species into Texas.…”

A recent increase in the abundance of snook species (Centropomus spp.) in Texas has been generally associated with a broad‐scale warming trend of Texas’ inshore waters, closure of the commercial fishery in 1987, and fairly conservative restrictions on recreational catch implemented at the same time. Despite this observed increase in abundance, little is known about the snook species complex in Texas, including uncertainty about recent changes in distribution and abundance, taxonomy, and population structure. Here, abundance and distribution data from a long‐running fishery‐independent (FIN) data set were analyzed in synergy with mitochondrial DNA (mtDNA) and microsatellite genotypes to answer basic questions about the snook species complex in Texas. The main findings from this work are as follows: (1) based on trends observed in FIN data, snook are increasing in abundance and expanding their range northward in Texas; (2) based on mtDNA sequencing, the two most common species of snook in Texas are the Common Snook C. undecimalis and Largescale Fat Snook C. mexicanus; (3) a third species, the Mexican Snook C. poeyi, occurs but only rarely; and (4) patterns from microsatellite genotypes suggest that the two predominant species, Common Snook and Largescale Fat Snook, probably constitute single genetic stocks in Texas, although evidence of chaotic genetic patchiness was also observed. This latter finding might be a general expectation for populations that are on the leading edge of an expanding species range and implies that management measures in Texas should be directed toward conservation of suitable habitat corridors offering environmental and habitat refugia as well as measures (e.g., stock enhancement) that increase the probability of survival of small, localized populations.

Centropomus is the sole genus of the Centropomidae family (Teleostei), comprising 12 species widely distributed throughout the Western Atlantic and Eastern Pacific, with 6 of them occurring in the Western Atlantic in extensive sympatry. Their life history and phylogenetic relationships are well characterized; however, aspects of chromosomal evolution are still unknown. Here, cytogenetic analyses of 2 Centropomus species of great economic value (C. undecimalis and C. mexicanus) were performed using conventional (Giemsa, Ag-NOR, and fluorochrome staining, C- and replication banding) and molecular (chromosomal mapping of 18S and 5S rDNA, H2A-H2B and H3 hisDNA, and (TTAGGG)_n repeats) approaches. The karyotypes of both species were composed of 48 solely acrocentric chromosomes (2n = 48; FN = 48), but the single ribosomal site was located in varying positions in the long arms of the second largest chromosome pair. Replication bands were generally similar, although conspicuous differences were observed in some chromosome regions. In both species, the histone H3 genes were located on 3 apparently homeologous chromosome pairs, but the exact position of these clusters differed slightly. Interspecific hisDNA and rDNA site displacements can indicate the occurrence of multiple paracentric inversions during the evolutionary diversification of the Centropomus genomes. Although the karyotypes remained similar in both species, our data demonstrate an unsuspected microstructural reorganization between them, driven most likely by a series of paracentric inversions.
