“…In this study, the genetic variation of wild population samples of Korean S. inermis was low relative to that reported in other Sebastes species (Rocha-Olivares et al, 2003;Buonaccorsi et al, 2002Buonaccorsi et al, , 2004, as well as other marine fishery species (DeWoody and Avise, 2000). However, similar genetic variability was reported in S. maliger (Wimberger et al, 1999) and S. thompsoni (Sekino et al, 2001).…”

ABSTRACT. The population structure of the black rockfish, Sebastes inermis (Sebastidae), was estimated using 10 microsatellite loci developed for S. schlegeli on samples of 174 individuals collected from three wild and three hatchery populations in Korea. Reduced genetic variation was detected in hatchery strains [overall number of alleles (N A ) = 8.07; allelic richness (A R ) = 7.37; observed heterozygosity (H O ) = 0.641] compared with the wild samples (overall N A = 8.43; A R = 7.83; H O = 0.670), but the difference was not significant. Genetic differentiation among the populations was significant (overall F ST = 0.0237, P < 0.05). Pairwise F ST tests, neighbor-joining tree, and Population genetic structure of black rockfish in Korea principal component analyses showed significant genetic heterogeneity among the hatchery strains and between wild and hatchery strains, but not among the wild populations, indicating high levels of gene flow along the southern coast of Korea, even though the black rockfish is a benthic, non-migratory marine species. Genetic differentiation among the hatchery strains could reflect genetic drift due to intensive breeding practices. Thus, in the interests of optimal resource management, genetic variation should be monitored and inbreeding controlled within stocks in commercial breeding programs. Information on genetic population structure based on cross-species microsatellite markers can aid in the proper management of S. inermis populations.

“…However, larval active movement ability in some species can hinder dispersion and favor population differentiation. Such is the case of Sebastes rastrelliger, a marine fish, whose larvae remain near their spawning area, thus reducing genetic exchange with other populations (Buonaccorsi et al, 2004).…”

Abstract:The Common Snook, Centropomus undecimalis, inhabits riverine and marine areas of Southern Gulf of Mexico, where it is subject to intense use and exploitation. It has been reported that the genetic identification of fish stocks constitutes a valuable tool for wild population management; nevertheless, there is no available information on the genetic identification on fish stocks of this species in the region. The aim of this study was to determine the genetic relationship between C. undecimalis captured in marine and freshwater environments of the Gulf of Mexico and the San Pedro River. For this, muscle tissue samples of 79 specimens were obtained from areas located more than 300km apart. The genotype of each individual was determined using seven microsatellite primer pairs. Five primers amplified efficiently presenting between six and 28 alleles per locus. High levels of heterozygosis were observed in samples from both environments. Deviation from HWE due to an excess of heterozygotes was observed. The values of genetic difference indicate an absence of population structure (F ST =0.0075 and R ST =0.016, p=0.051) and similarity in the allele frequencies, defined by Nei's index (0.805). Data showed the existence of a high gene flow due to the number of migrants (Nm=18.7). Our results suggest that individuals living in these environments belong to the same genetic population. We suggest the development of management and protection plans for this fish species population in the wild. Rev. Biol. Trop. 62 (2): 627-636. Epub 2014 June 01.Key words: genetic diversity, microsatellite, Common Snook, Centropomus undecimalis, Grijalva-Usumacinta fluvial system, Gulf of Mexico.The Common Snook, Centropomus undecimalis, is a euryhaline species with migratory activity between marine, estuarine and fluvial environments throughout its life cycle. Its geographic range is limited to the Atlantic coast of the American continent, extending from Florida, USA, to Brazil (McMichael, Peters, & Parsons, 1989;Tringali & Bert, 1996;Tringali, Bert, & Seyoum, 1999;Taylor, Whittington, Grier, & Crabtree, 2000). Reproduction of C. undecimalis in the Gulf of Mexico has been reported to occur in subtidal areas along the coast or within estuaries and coastal lagoons. Spawning takes place between April and September at salinities ranging from 28 to 35psu (Tucker, 1987;Tringali & Bert, 1996; (Anonymous, 2006;Perera, Mendoza, Contreras, Huerta, & Pérez, 2011;Perera-García et al., 2013). Capture is strongly associated to migratory movements in freshwater ecosystems; while in the coastal zone, capture is linked to spawning events. These situations can promote stock depletion with potential detrimental effects on population conservation (Perera et al., 2011).The Grijalva-Usumacinta fluvial system is the largest in Central America; it discharges into the Gulf of Mexico at the Campeche Bank area. One of the most important tributaries of this system is the San Pedro River -a freshwater tributary-located near the border with Guatemala. This river ...

However, recent studies have elucidated the importance (4,5) and apparent ubiquity of self-recruitment (i.e., retention of locally produced young) for population replenishment in many tropical species (6)(7)(8)(9)(10)(11) and the potential for limited dispersal along open coasts in temperate systems (12)(13)(14)(15).

There is a growing realization that the scale and degree of population connectivity are crucial to the dynamics and persistence of spatially structured populations. For marine organisms with complex life cycles, experiences during larval life may influence phenotypic traits, performance, and the probability of postsettlement survival. For a Caribbean reef fish (Thalassoma bifasciatum) on an oceanic island, we used otolith (ear stone) elemental profiles of lead (Pb) to assign recent settlers to a group that developed in waters elevated in Pb concentrations throughout larval life (i.e., nearshore signature) and a group that developed in waters depleted in Pb (i.e., offshore signature), potentially dispersing from upstream sources across oceanic waters. Larval history influenced early life history traits: offshore developers initially grew slowly but compensated with fast growth upon entering nearshore waters and metamorphosed in better condition with higher energy reserves. As shown in previous studies, local production contributed heavily to settlement: at least 45% of settlers developed nearshore. However, only 23% of survivors after the first month displayed a nearshore otolith profile. Therefore, settlers with different larval histories suffered differential mortality. Importantly, selective mortality was mediated by larval history, in that the postsettlement intensity of selection was much greater for fish that developed nearshore, potentially because they had developed in a less selectively intense larval environment. Given the potential for asymmetrical postsettlement source-based survival, successful spatial management of marine populations may require knowledge of ''realized connectivity'' on ecological scales, which takes into account the postsettlement fitness of individuals from different sources.larval-juvenile transition ͉ otolith chemistry ͉ realized connectivity ͉ selective mortality ͉ Thalassoma bifasciatum P opulations of many coastal marine species are connected primarily by dispersal during a relatively short pelagic larval phase (i.e., days to months), because most species have limited adult movement. For much of the last 30 years, researchers assumed that marine populations were demographically open. Models of open populations (1) suggested that larval supply was decoupled from local demographic rates (2). This view was reinforced by the assumption that larvae behaved as passive particles dispersed widely by ocean currents (e.g., ref.3). However, recent studies have elucidated the importance (4, 5) and apparent ubiquity of self-recruitment (i.e., retention of locally produced young) for population replenishment in many tropical species (6-11) and the potential for limited dispersal along open coasts in temperate systems (12-15). Both physical oceanographic processes (16) and larval behavior (17) may prevent advection and promote the retention of developing larvae in nearshore waters.Despite the recent evidence for local replenishment in island systems, the young that recruit to an island are ...
