Population Genetic Structure, Movement Patterns, and Environmental Preferences of the Pelagic Wahoo, Acanthocyhium solandri
Title
Population Genetic Structure, Movement Patterns, and Environmental Preferences of the Pelagic Wahoo, Acanthocyhium solandri.
Creator
Theisen, Timothy Charles, Florida Atlantic University, Baldwin, John D., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description
The wahoo, Acanthocyhium solandri, is a pelagic marine fish which inhabits tropical, subtropical, and warm temperate waters worldwide. Despite being highly mobile and economically important over most of their range, there is little scientific data concerning population structure, movement patterns, or environmental preferences of wahoo. In this study I investigate wahoo genetic population structure and phytogeography on a global scale, and deploy pop-up satellite archival tags (PSA T's) in...
Show moreThe wahoo, Acanthocyhium solandri, is a pelagic marine fish which inhabits tropical, subtropical, and warm temperate waters worldwide. Despite being highly mobile and economically important over most of their range, there is little scientific data concerning population structure, movement patterns, or environmental preferences of wahoo. In this study I investigate wahoo genetic population structure and phytogeography on a global scale, and deploy pop-up satellite archival tags (PSA T's) in the western Atlantic Ocean to determine movement patterns and environmental preferences of wahoo. Wahoo population genetic structure was examined across their entire global range with intron six of lactate dehydrogenase-A (ldhA6, 10 locations, N = 213) and mtDNA cytochrome h (Cyth, 13 locations, N = 322). Results show extensive sharing ofhaplotypes and no significant structure between all locations (mtDNA ~ST < 0.0001, P = 0.634; nuclear FsT = 0.0125, P = 0.1 06). Overall nuclear heterozygosity (H = 0.714) and mtDNA haplotype diversity (h = 0.918) are both high, while overall mtDNA nucleotide diversity (n = 0.006) and nuclear nucleotide diversity (n = 0.004) are uniformly low. Coalescence indicates an effective female population size CNeF) at - 816,000, and a population bottleneck - 690,000 years ago. Movement patterns and environmental preferences were investigated by deploying PSA T's onto four individual wahoo in the western Atlantic Ocean. Tagging success rate (75%) validates the deployment protocol developed for this project. Results indicate that wahoo in the western Atlantic ocean spend the greatest portion of their time between 0 and 20 meters of depth, and between temperatures of 20oC and 26°C. More time was spent near the deeper extremes of their range during the nocturnal period, and daily visits to the surface were observed. Wahoo were observed traveling north in Fall and Winter, contrary to previous notions concerning the migratory movements of this species. The genetic results indicate a worldwide stock for wahoo, which reinforces the mandate for international cooperation on fisheries issues. The PSA T results demonstrate the value of the acquired data to the investigation of important life history parameters in pelagic species. The information generated from this project will benefit fisheries managers, marine biologists, evolutionary biologists, and both commercial and recreational fishing interests.

It is concluded that Florida specimens have the same range in morphological variability as specimens from Isreal. The experimental work completed here indicates that Tilapia aurea does not adversely affect native fish populations. It is speculated that Tilapia aurea may have stabilized the experimental fish populations by a "polyculture effect."

Show moreThe Gulf of Mexico (GoM) contains a variety oceanographic features including; the Loop Current, cyclonic/anticyclonic eddies, common water, and the Mississippi River Plume. The relationship these features have on the community assemblages of Families Lutjanidae and Serranidae has been of great interest from both biological and economic standpoints. These families represent some of the most economically important fisheries in the GoM. Identifying the role these features play in the transportation of larval and juvenile nearshore species to offshore environments is vital to resource managers. Using data collected shortly after the Deepwater Horizon Oil Spill via the NOAA Natural Resource Damage Assessment in 2011 as well as cruises conducted by the Deep Pelagic Nekton Dynamics of the Gulf of Mexico (DEEPEND) Consortium from 2015-2017, the faunal composition and abundance of these families were analyzed with respect to seasonality, oceanographic features, depth distribution, and time.

Abstract/Description
The fish communities of two seagrass habitats near Jupiter Inlet, Florida, were studied from April 1981 to March 1982 to determine species composition, abundance, richness and occurrence. Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch.

Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch. The presence of young lutjanids, haemulids, serranids and sphyraenids indicates the role of this area as a nursery ground. Temporal patterns in species composition and abundance were examined through numerical classification. Species composition was more consistent over time than were corresponding abundances. Despite their proximity, the two sites exhibited differences in species composition and abundance. The role of biological, physical and historical factors are discussed in relation to the observed community patterns.

Dry down periods are common in some marshes, making life difficult for fish and other aquatic organisms. The goal of this study was to compile an updated species list of fishes inhabiting the freshwater marsh system within Savannas Preserve State Park. Twenty-three fish species were collected between August 2005 and May 2007. This survey, along with past collections, and the current species list in the park's management plan were used to make a new proposed species list. Three species of nonnative fishes were observed during the study, the first report of exotic fishes in the park. It is believed that abnormally high water levels for an extended period may have allowed the water in neighboring canals to connect to the marsh system and, as a result, new species were able become introduced in the park.

Results of construction of the C-38 canal included loss of continuous flow of water and loss of floodplain habitat which adversely impacted the fish community. In 1984 the South Florida Water Management District (SFWMD) constructed the Pool B demonstration project to evaluate the feasibility of a planned restoration project. To evaluate success of the demonstration project in enhancing the Pool B fish fauna, a hoop net sampling program was conducted in 1996. The data suggest that black crappie (Pomoxis nigromaculatus) and other sport species in Pool B are benefiting from habitat enhancements resulting from the demonstration project. Additional analysis distinguishes black crappie as the only centrarchid sampled that maintains activity during nocturnal hours. Bluegill (Lepomis macrochirus) were most active during May sampling when water temperatures were optimal for spawning.
