“…Daily otolith increment formation has been validated in Lutjanus griseus, L. synagris, L. apodus and Ocyurus chrysurus (Lindeman 1997, Allman 1999, Ahrenholz 2000, Allman & Grimes 2002, Mikulas & Rooker 2008 and was assumed in L. analis and Etelis oculatus. Overall similarity in increment widths and appearance between these species and those that have been validated were consistent with this assumption.…”

Despite the ecological and economic importance of western Atlantic Ocean lutjanid species, little is known about their larval stage. Pelagic larval distribution, abundance, growth, mortality, and spawning patterns of 6 western Atlantic snapper species were examined from ichthyoplankton samples collected monthly over 2 yr along a transect spanning the east -west axis of the Straits of Florida (SOF). Successful spawning occurred primarily from July to September when water temperatures were warmest and larvae were most abundant in the upper 50 m towards the east or west sides of the SOF. Species-specific variability in spatiotemporal larval patterns tracked adult life history characters. Larvae of species associated with shallow coral reefs were spawned in the waning half of the lunar cycle (third quarter to new moon), were most abundant in the 0 to 25 m depth range, and where cross-SOF distributions were not uniform, were distributed mainly towards the eastern SOF. Larvae of deeper-dwelling species exhibited lower mortality and no lunar pattern in spawning (Etelis oculatus only), were distributed deeper in the water column and occurred progressively deeper with ontogeny, and where cross-SOF distributions were not uniform, were most abundant in the western SOF. Despite species-specific variability in spatial distributions and equivalent east -west mortality rates, at least one measure of larval growth in 4 of 6 species of snapper revealed significantly faster growth in the western versus the eastern SOF, which may be related to higher prey availability in the west. Results of this study provide insight into the pelagic phase of 6 important snapper species, with implications for understanding adult populations.

Although adults undertake spawning migrations and ontogenetic movements of juveniles connect nearshore habitats, the primary process determining connectivity between fragmented adult populations is believed to be dispersal of the pelagic larval stage (Pineda et al. 2007). Larval dispersal may be influenced by a variety of factors in the pelagic environment (e.g. currents, larval behavior, vertical distribution, growth and mortality). Understanding the effects of these factors is critical in light of the importance of connectivity for establishing and implementing spatially based fishery management (Fogarty & Botsford 2007).Despite their economic importance, little is known about the early life history (ELH) of lutjanids.

“…This bathymetric high runs northeast to southwest for *20 km with the ridge crest located between 15 and 20 m depth. FRBH was surveyed and mapped using a Global Positioning System (GPS) integrated side scan sonar (Edgetech 272 TD at 500 kHz) (Mikulas & Rooker, 2008). Results indicated substrates along the crest were composed of shell hash and sand with patches of relic oyster beds, while adjacent mud bottom was present on both the inshore and offshore areas surrounding the ridge crest.…”

Fish assemblage structure on a drowned barrier island in the northwestern Gulf of Mexico

et al. 2009

We investigated the assemblage structure of fishes associated with different habitats (inshore mud, shell bank, and offshore mud) over a drowned barrier island, Freeport Rocks Bathymetric High, on the inner continental shelf of the northwestern Gulf of Mexico (NW Gulf). Density data from otter trawls were used to examine spatial (habitat and site) and temporal differences in fish assemblage structure using multi-and univariate procedures. Eight species accounted for 69% of the total composition and in order of decreasing abundance included shoal flounder (Syacium gunteri), dwarf sand perch (Diplectrum bivittatum), red snapper (Lutjanus campechanus), least puffer (Sphoeroides parvus), silver seatrout (Cynoscion nothus), largescale lizardfish (Saurida brasiliensis), silver jenny (Eucinostomus gula), and sand seatrout (Cynoscion arenarius). Multivariate results indicated fish assemblage structure differed among habitats (ANOSIM; Global R = 0.190, P \ 0.001) and survey dates (ANOSIM; Global R = 0.541, P \ 0.001); however, differences among sites were negligible (ANOSIM; Global R = -0.015, P = 0.749). Highest densities of dwarf sand perch and least puffer were found on the shell bank, while densities of shoal flounder, largescale lizardfish, and silver jenny were highest on offshore mud. In addition, smallest sizes and highest densities of six of the eight abundant species were found in July, suggesting an important period for juvenile fishes. Diversity indices also varied relative to habitat with highest Shannon diversity (H 0 ) and species richness (S) values for fishes associated with the shell bank. Results of this study highlight the importance of a mosaic of habitat types to fish assemblages on a drowned barrier island in the NW Gulf.

“…Despite significant sampling efforts, they collected relatively few juvenile red snapper from the west Florida shelf, and had no samples from that region for 1 of the 3 yr classes they examined. Lane snapper Lutjanus synagris, however, are abundant on the west Florida shelf, thus the question arose as to whether lane snapper otolith chemical signatures could serve as a proxy for those of red snapper, given similarities in ecology, early life history, and GOM habitats between these 2 congeners (Workman et al 2002, Mikulas & Rooker 2008. To test this question, age-0 red and lane snapper juveniles were sampled concurrently among 3 northern GOM regions, and differences in otolith chemical signatures between species were tested.…”

“…Red and lane snappers have overlapping spawning seasons in the northern GOM, thus juveniles likely were present on the shelf and exposed to ambient conditions over the same time period. The large size for lane snapper juveniles may result from faster growth, as their mean growth rate tends to be on the upper end of the range observed for red snapper juveniles (Mikulas & Rooker 2008.…”

“…Not only are they closely related phylogenetically (Gold et al 2011), they also have very Table 1 (Workman et al 2002, Mikulas & Rooker 2008. Juveniles typically spend at least their first year of life associated with these habitats prior to recruiting to reefs later in their second year of life, and their feeding ecologies overlap as well, with juvenile diets consisting principally of zooplankton, benthic invertebrates, squids, and transitioning to greater piscivory with ontogeny (Franks & VanderKooy 2000, W. F. Patterson et al 2005, McCawley & Cowan 2007, Mikulas & Rooker 2008. Therefore, few species are as similar phylogenetically and ecologically in the northern GOM as red and lane snappers, factors that Swearer et al (2003) and Chang & Geffen (2013) concluded had great influence on the similarity of otolith chemical signatures between species.…”

, Crowder et al. 2006, Ciannelli et al. 2013. Several approaches have been developed to examine population structure and connectivity among invertebrate and vertebrate marine fauna, including molecular techniques, modeling egg and larval transport, and applying artificial and natural tags to examine population connectivity. In reef fishes, results O). Chemical signatures were significantly different among regions (MANOVA, p < 0.001) and between species (MANOVA, p = 0.029), with the species effect being driven by significant differences in 4 of the 7 constituents analyzed (ANOVA, p < 0.036). The significant region effect persisted (MANOVA, p < 0.001), but the species effect was non-significant (MANOVA, p = 0.964) when constituent values were normalized to species-specific means. Mean regional classification accuracies from linear discriminant functions computed with otolith constituent data were 84% for lane snapper and 80% for red snapper whether data were normalized or not. Maximum likelihood models parameterized with normalized lane snapper otolith chemistry data estimated red snapper regional composition reasonably well among mixed-region samples (mean error = 9.7% among models). Therefore, it appears age-0 lane snapper otolith chemical signatures can serve as accurate proxies for those of red snapper in the northern GOM. These results have broader implications for deriving natural tags based on otolith chemistry for fishes that may have low abundance in parts of their range.
