- Can Differences in Microhabitats Influence Disease Prevalence of Perkinsus marinus in Oysters?.
- Creator
- Lara, Pedro U., Laramore, Susan E., Harbor Branch Oceanographic Institute
- Abstract/Description
-
Habitat refuges are important ecological spatial components that can alter the survivability of organisms by providing relief from ecological pressure, such as predation, disease prevalence, and environmental stressors. If a habitat is considered to be a disease refuge this means that something unique occurred that reduced disease prevalence and intensity. Two different types of oyster habitats (mangroves and reefs) and micro habitats (low and high prop roots and reefs) were studied to...
Show moreHabitat refuges are important ecological spatial components that can alter the survivability of organisms by providing relief from ecological pressure, such as predation, disease prevalence, and environmental stressors. If a habitat is considered to be a disease refuge this means that something unique occurred that reduced disease prevalence and intensity. Two different types of oyster habitats (mangroves and reefs) and micro habitats (low and high prop roots and reefs) were studied to determine whether differences in the internal environmental of oysters varied between habitats. Analysis of internal oyster surface and body temperatures along with oyster body salinity showed that differences in microhabitats affected body temperature and salinity. Oysters in both mangrove habitats exhibited lower body salinity and lower temperature than those on oyster reefs. We also analyzed disease prevalence and intensity of Perkinsas marinas among the different habitats and micro habitats by collecting oysters that were >1 year old. Results indicated variability of disease prevalence and intensity among the different habitats, with lowered disease prevalence and intensity seen on mangrove prop roots. These results indicate that mangrove prop roots may provide a habitat refuge for oysters from the parasite Perkinsas marinas.

- Confirmation of Bouamia spp. in Bivalves in the Indian River Lagoon Using Fluorescent in situ Hybridization.
- Creator
- Cheng, Susan, Laramore, Susan E., Harbor Branch Oceanographic Institute
- Abstract/Description
-
Various bivalve species were sampled at three sites in the Indian River Lagoon in Fort Pierce, Florida to determine whether the change in the seasonal prevalence of Bonamia spp. in the Indian River Lagoon as determined by PCR could be confirmed histologically using standard hematoxylin and eosin (H&E) staining and fluorescent in situ hybridization (FISH). Parasite location was noted in tissue samples and determinations were made as to whether the infection was external (gills, mantle) or...
Show moreVarious bivalve species were sampled at three sites in the Indian River Lagoon in Fort Pierce, Florida to determine whether the change in the seasonal prevalence of Bonamia spp. in the Indian River Lagoon as determined by PCR could be confirmed histologically using standard hematoxylin and eosin (H&E) staining and fluorescent in situ hybridization (FISH). Parasite location was noted in tissue samples and determinations were made as to whether the infection was external (gills, mantle) or internal (connective tissue). Bonamia spp. was found to be more prevalent in the fall at all three study sites. Fluorescent in situ hybridization confirmed the majority ofPCR-positive samples. A large percentage of Bonamia spp. infections at North Causeway Park and Wabasso Causeway Bridge were external infections. In addition, a large percentage of Bonamia spp. infections at Wildcat Cove and Wabasso Causeway Bridge were in the gills and mantle. This indicates that most of the bivalves sampled are filtering the parasite from their surrounding environment but are not being negatively affected and those that are infected are not heavily infected. Bonamia spp. has not been reported to negatively impact bivalve populations in Florida, however the impacts of this parasite on various oyster and mussel species in Florida has not been thoroughly examined. This project may determine what steps need to be taken to prevent the losses in oyster and associated bivalve populations in the Indian River Lagoon.

Bivalves are important aquatic species that are an integral part of food web dynamics and nutrient cycling. As filter feeding organisms, bivalves impact on aquatic habitats, includes their ability clean up the surrounding water which allows under water plants to receive sunlight, increase oxygen and provide additional habitat to that provided by created oyster reefs.

Show moreBivalves are important aquatic species that are an integral part of food web dynamics and nutrient cycling. As filter feeding organisms, bivalves impact on aquatic habitats, includes their ability clean up the surrounding water which allows under water plants to receive sunlight, increase oxygen and provide additional habitat to that provided by created oyster reefs. Oyster diseases such as Bonamiosis caused by the parasite Bonamia spp. may decimate bivalve populations, causing a potential threat to the habitat of other aquatic organisms. The objective of this study was to identify the seasonal prevalence of Bonamia spp. in bivalve populations and correlate that to its environmental preference (i.e. salinity, temperature.). The results of this study show that Bonamia spp. is not only present in multiple sites and multiple bivalve species in the Indian River Lagoon, FL but is more prevalent in the fall compared to the other seasons as is seen with other oyster parasites, such as Perkinsus spp. This points for the need for additional studies to determine if Bonamia spp are having an impact on the bivalve populations in Florida and whether this parasites is causing an impact to the surrounding environment.

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.

Five years later, the program has accrued an abundance of data with the daily help of numerous volunteers. This project compiles and analyzes the data to answer questions about the abundance and behaviors of the resident population of manatees in the Harbor Branch channel. The manatees were found to have a general yearly abundance trend having high numbers in the winter and preferring to aggregate in the West Basin. There is no obvious effect of the 2010 cold stun, however, further research involving photo-identification analysis needs to be completed. The main behaviors exhibited in the challllel involve resting, staying warm, and mating, signifying that the channel is an important habitat for manatees. This project will continue as part of the researcher's undergraduate thesis.
