“…The inshore waters of Texas represent a latitudinal environmental cline of salinity and temperature, both of which increase from north to south (Table 1). Snook species are vulnerable to acute temperature extremes, particularly cold/freeze events (Shafland and Foote 1983;Adams et al 2012;Stevens et al 2016), such that their distribution has historically been limited to lower latitudes in Texas where water temperatures are more tolerable (Matlock and Osburn 1987;Pope et al 2006). It has been suggested that the natural range of snook species could expand further north given the current climatic warming trend; such a range expansion has been reported in another subtropical/tropical-associated species in Texas, the Gray Snapper Lutjanus griseus, and has been hypothesized for other species with similar thermal tolerance ranges (Tolan and Fisher 2009).…”

“…Snook were the target of a short-lived commercial fishery in Texas. The fishery crashed in the late 1920s, and recreational catch declined within the same general time frame (Matlock and Osburn 1987). It was hypothesized that this dramatic decline in snook abundance was driven by two factors: cold weather events and overfishing, although it is unknown whether other factors may have also played a role (Matlock and Osburn 1987).…”

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.

“…Common snook form the basis of important fisheries throughout their range due to their sporting and culinary attributes (Tucker et al, 1985;Matlock & Osburn, 1987). Numbers of common snook have declined over recent years due to shoreline development, fishing pressure, and loss of coastal habitats.…”

In recent years, the abundance and distribution of snook species (Centropomus spp.) have increased and expanded in Texas. As mobile predators, snook have the potential to alter marine communities as they expand; however, little is known about the functional impact of snook in Texas. Here, a long-term (1982-2019) fishery-independent data set was utilized to describe snook life history characteristics. Bag-seine and gill-net data were used to determine distribution, size, spawning, and recruitment seasonality for Common Snook C. undecimalis and Fat Snook C. parallelus in Texas. Snook collected from the lower Laguna Madre were used to describe diet, length-weight relationships, and sex ratios. Results indicated that both Common and Fat snook abundance and range increased in Texas with expansion primarily led by Common Snook. Common Snook were larger than Fat Snook based on the length frequency analysis, but the latter were heavier at a given length. Spawning season for both species occurred during summer and peaked in July and August for Fat and Common snook, respectively. Evidence for protandric hermaphroditism was observed in Common Snook with females being significantly larger than males and a 50:50 male-to-female ratio occurring at 670 mm total length (TL). Diet analyses indicated that Common and Fat snook are generalist predators feeding on a variety of prey species. An ontogenetic shift in diet was observed in Common Snook as individuals <500 mm TL fed primarily on shrimp, and those ≥500 mm TL fed primarily on fish. Fat Snook and subadult Common Snook possessed a high degree of dietary overlap, with shrimp being the most common prey item identified for each. These findings provide managers with the foundational aspects of snook life history at a time when the potential effects of the snook range expansion in Texas remain largely undescribed.
