With the current decline in world fisheries it is necessary to develop more sustainable methods of marine resource production. An Integrated Multi-Trophic Aquaculture (IMTA) system is one such method. In an IMT A system the waste nutrients of fed species are used to culture other species, thus increasing the efficiency of feed use. A land-based IMTA (LB-IMTA) system was utilized in the cunent study in which one of the waste nutrient utilizing species was oysters. Oysters in this system were...
Show moreWith the current decline in world fisheries it is necessary to develop more sustainable methods of marine resource production. An Integrated Multi-Trophic Aquaculture (IMTA) system is one such method. In an IMT A system the waste nutrients of fed species are used to culture other species, thus increasing the efficiency of feed use. A land-based IMTA (LB-IMTA) system was utilized in the cunent study in which one of the waste nutrient utilizing species was oysters. Oysters in this system were determined to be not getting an adequate amount of waste nutrient feed necessary for normal growth. Therefore, oysters would need supplemental microalgae to grow normally, however the addition ofmicroalgae to the LB-IMTA might have detrimental effects, e.g., spreading throughout the system and changing the balance of nutrient flow or blooming throughout the system. Therefore, a study was designed to determine the fate of microalgae added to an LB-IMTA under a worst case scenario. With no oysters in the LB-IMTA system (total volume 61,740 L), 30 L ofmicroalgae (average density= 6.3x106 cells/mL) were added into the oyster tanks. Microalgae cells were tracked over time by sampling at distinct sites throughout the LB-IMTA system. Microalgae concentrations (i.e., #/mL) in the samples were determined with the aid of a Flocam®. Three microalgae species were individually tested: Dunaliella tertiolecta, Chaetoceros gracilis, and Isochrysis galbana Caribbean strain. Overall, the data indicated that all three micro algae species spread to almost all parts of the system after only 15 minutes, but nearly all of the microalgae was gone after 3 hrs; avg. = 8 cells/mL, which was 0.26% of the average theoretical homogenous concentration (3061 cells/mL). The primary removal of microalgae was most likely by the bead filters, which remove fine particles. The filtration components of the HBOI LB-IMTA were able to remove the excess microalgae and should limit any potentially detrimental effects caused by an overabundance of microalgae.

Show moreThe Florida pompano, Trachinotus carolinus, is an ideal species for commercial aquaculture because of its rapid growth, tolerance to a range of environmental parameters, and high demand in the seafood market. This study detailed embryonic and early larval development of this species. Florida pompano followed similar developmental sequences to those observed in other marine teleosts, and embryos hatched between 22 and 28 h post-fertilization. Significant brain lobe differentiation occurred prior to hatching. Pectoral fins were functional within 1-day post-hatch (dph). Substantial eye development occurred within 3 dph, indicating visual acuity prior to the onset of exogenous live feeding. Intestinal segments were differentiated by 3 dph, and rotifers were seen in the digestive tract by 4 dph. Digestive functions were limited through the first 7 dph because of the absence of functional gastric glands and gastric mucous cells in the rudimentary stomach, lipid vacuoles in the anterior intestines, and the persistence of acidophilic supranuclear vesicles in the posterior intestines. Within 7 dph, the pharyngeal arches differentiated, and hematopoietic tissue and mesonephric tubules were visible in the larval kidney. Their rapid larval development and organogenesis are additional factors that make Florida pompano an ideal species for aquaculture production and should encourage continued efforts toward commercialization

Show moreFlorida pompano (Trachinotus carolinus) are a species of growing interest for commercial aquaculture. Effective health monitoring is crucial to the successful growout of the species, and prophylactic and therapeutic use of chemicals and antibiotics has been the traditional strategy for promoting stock health. However, concerns about antimicrobial resistance, chemical residues in seafood products and the environment, and resultant immunosuppression have prompted the industry to identify alternative management strategies, including supplementation with prebiotics, probiotics, and combinations of both (synbiotics). The objectives of this study are to determine and compare hematological, plasma biochemical, and plasma protein electrophoresis data of synbiotic-supplemented (β-glucan and Pediococcus acidilactici) and nonsupplemented Florida pompano. Reference intervals for blood analytes are provided for both groups and for subgroups (females, males, large, and small fish) where statistically significant results exist. There are no differences between the hematological and plasma biochemistry analytes between the supplemented and control groups, except for blood urea nitrogen and carbon dioxide, indicating a possible effect of synbiotic supplementation on gill function and osmoregulation. Sex-related and sizerelated differences are observed within each of the control and supplemented groups; however, biometric measurements do not strongly correlate with blood analytes. These data represent baseline hematological and plasma biochemical data in the Florida pompano and indicate the safety of synbiotic supplementation in this commercially important species. This study serves to further the commercialization of Florida pompano by providing blood analyte reference intervals for health monitoring in the aquaculture setting.

Florida Pompano Trachinotus carolinus are molluscivorous, greater than 70% of their natural diet consists of hard-shelled gastropods and bivalves. A specialized feeding mechanism (pharyngeal jaw) forms a crushing surface used to grind prey.

A specialized feeding mechanism (pharyngeal jaw) forms a crushing surface used to grind prey. In aquaculture, extruded pellets are fed and this feeding apparatus results in pellets fracturing and loss of fragments through their gill rakers. The effect of pellet form (hard vs. soft) and size on fractured pellet waste (FPW) and production characteristics of Pompano reared in recirculating aquaculture systems was addressed. No difference in FPW between the standard pellet size and smaller pellet size treatments. However, a difference in FPW at first feeding of the day between the hard and soft pellet treatments was observed, with no difference in FPW present at the last feeding. Results suggest that pellet size does not reduce the amount of FPW produced, while the use of soft pellets reduces the amount of FPW.

A major factor limiting pond aquaculture productivity is fluctuating oxygen levels, which are heavily influenced by atmospheric conditions and primary productivity. Being able to predict DO concentrations by measuring environmental parameters would be beneficial to improving the industry’s efficiencies. The data collected included pond DO, water temperature, air temperature, atmospheric pressure, wind speed/direction, solar irradiance, rainfall, pond Chl-a concentrations as well as water color images. Pearson’s correlations and stepwise regressions were used to determine the variables’ connection to DO and their potential usefulness for a prediction model. It was determined that sunlight levels play a crucial role in DO fluctuations and crashes because of its influence on pond heating, primary productivity, and pond stratification. It was also found that image data did have correlations to certain weather variables and helped improve prediction strength.

Show moreThe goal of this project is to gain access to valuable genetic information that will be utilized to create a genetics-based selective breeding program. This selective breeding program will be implemented to produce and maintain a healthy and diverse breeding stock of the Florida Pompano Trachinotus carolinus. The Florida Pompano is a popular food fish found in abundance off Florida's east and west coasts. There has been interest in the aquaculture of this species for decades with minimal success. With recent improvements in aquaculture systems and nutrition, now is the time to bring this fish to commercialization. The main research objectives of this study are to create a bioinformatics workflow to generate a draft whole-genome of the Florida Pompano, identify variation sites within this genome, and run a comparative analysis with two closely related Trachinotus species, Permit T. falcatus and Palometa T. goodei. These two species were chosen because they are found in the same environment as the Florida Pompano but grow to substantially different sizes. To sequence and assemble the whole genome of the Florida Pompano, a hybrid method was applied using long and short-read sequencing technologies. The draft genome was found to be 733.5 Mb in length with a total of 26,891 protein-coding genes. Sites of variation within this assembled genome were identified using a 2b-RAD sequencing method on 62 individuals collected off Florida’s east and gulf coasts.
