“…The Gulf of Honduras also acts as a geographic barrier promoting a pattern of counterclockwise circular currents that keeps larvae near the coast and restricts migration to adjacent areas. Our results agree with the patterns of the currents of the Mesoamerican Reef System hydrography and with the flow pattern's cyclonic circulation known as the Honduras Gyre (Carrillo et al, ). Still, the finding of P. miles in Banco Chinchorro (Guzmán‐Méndez, Rivera‐Madrid, Díaz‐Jaimes, García‐Rivas, et al, ) evidence that the dispersion process of both species ( P. miles and P. volitans ) is constant and increasing.…”

Lionfish (Pterois volitans) have rapidly invaded the tropical Atlantic and spread across the wider Caribbean in a relatively short period of time. Because of its high invasion capacity, we used it as a model to identify the connectivity among nine marine protected areas (MPAs) situated in four countries in the Gulf of Mexico and the Caribbean Sea. This study provides evidence of local genetic differentiation of P. volitans in the Gulf of Mexico and the Caribbean Sea. A total of 475 lionfish samples were characterized with 12 microsatellites, with 6-20 alleles per locus. Departures from Hardy-Weinberg equilibrium (HWE) were found in 10 of the 12 loci, all caused by heterozygous excess. Moderate genetic differentiation was observed between Chiriviche, Venezuela and Xcalak, México localities (F ST = 0.012), and between the Los Roques and the Veracruz (F ST = 0.074) sites. STRUCTURE analysis found that four genetic entities best fit our data. A unique genetic group in the Gulf of Mexico may imply that the lionfish invasion unfolded both in a counterclockwise manner in the Gulf of Mexico. In spite of the notable dispersion of P. volitans, our results show some | 3845 GUZMÁN-MÉNDEZ Et al.

“…This species has a similar life cycle as L. griseus, therefore the results of this project support the findings by these authors. The Yucatan current (average speed of 1.5 m/s), which later becomes the Loop Current (Athié et al, 2011), can export fish larvae from the Caribbean up to the Gulf of Mexico (Carrillo et al, 2015). Possibly these ocean dynamics favor the dispersion of L. griseus larvae.…”

Background: The gray snapper (Lutjanus griseus) has a tropical and subtropical distribution. In much of its range this species represents one of the most important fishery resources because of its high quality meat and market value. Due to this, this species is vulnerable to overfishing, and population declines have been observed in parts of its range. In recent decades, it has been established that knowing the level of genetic connectivity is useful for establishing appropriate management and conservation strategies given that genetic isolation can drive towards genetic loss. Presently the level of genetic connectivity between subpopulations of L. griseus of the southern region of the Gulf of Mexico and the Caribbean Sea remains unknown. Methods: In the present study we analyze genetic structure and diversity for seven subpopulations in the southern Gulf of Mexico and the Mexican Caribbean Sea. Eight microsatellite primers of phylogenetically closely related species to L. griseus were selected. Results: Total heterozygosity was 0.628 and 0.647 in the southern Gulf of Mexico and the Mexican Caribbean Sea, however, results obtained from AMOVA and R ST indicated a lack of genetic difference between the major basins. We also found no association between genetic difference and geographic distance, and moderately high migration rates (N m = > 4.1) suggesting ongoing gene flow among the subpopulations. Gene flow within the southern Gulf of Mexico appears to be stronger going from east-to-west. Conclusions: Migration rates tended to be higher between subpopulations within the same basin compared to those across basins indicating some regionalization. High levels of genetic diversity and genetic flow suggest that the population is quite large; apparently, the fishing pressure has not caused a bottleneck effect.

“…According to Carrillo et al (2015), the general pattern of surface water currents along the Quintana Roo coast is from south to north, as is the Yucatán Current (Figure 6.68). Although reversals in longshore transport south of Cancú n occur in the nearshore reef between rock headlands, the Yucatán Current, coupled with wave refraction, produces a net northward current for all littoral areas along the northeast coast of Quintana Roo (Krutak and Gío-Argáez 1994).…”
