Study Notes
Oyster Restoration Project Key Concepts
- Ostrea edulis: Native oyster species in the Atlantic and Mediterranean.
- Protandrous hermaphrodites: Oysters begin as males, then become females.
- Filter feeders: Oysters consume algae and detritus from seawater.
- Water filtration (16 pints/hour): Oysters filter a significant volume of water, improving water quality.
- Ecosystem services: Benefits provided by oysters to marine environments.
- Habitat stabilization: Oysters stabilize marshes and soft sediment areas.
- N & P cycling: Oysters help cycle nitrogen and phosphorus in ecosystems.
- Carbon sequestration: Oysters capture carbon, aiding climate regulation.
- Refugia function: Oysters offer refuge from predators for other species.
- Over-exploitation: Excessive harvesting leading to population decline.
- Bonamia ostreae: A parasite causing disease in Ostrea edulis oysters.
- Disease prevalence: Frequency of disease occurrence in oyster populations.
- Invasive species (Crepidula fornicata, Magallana gigas): Non-native species potentially displacing native oysters.
- Solent Seascape Restoration Project: An initiative to restore native oyster ecosystems in the Solent.
- Broodstock cages: Structures supporting oyster breeding and protection.
- Larval recruitment: The process of new oyster larvae settling in habitats.
- Histology, PCR diagnostic tests: Methods for diagnosing disease and identifying pathogens.
- Seabed density: Measurement of oyster population per area.
- Skewed sex ratio: Imbalance in male/female oyster populations.
- Oyster life cycle: Stages of development from larva to adult.
- Eutrophic control: Management of nutrient-rich waters to prevent algal blooms.
- Settlement plates: Tools to enhance oyster larval settlement.
- Gel electrophoresis: Technique separating DNA for disease analysis.
- Haplosporidian protist: A group of parasites including Bonamia ostreae.
- Oyster mortality: Death rate of oysters due to various factors.
- Benthic substrate: Bottom environment for oyster growth.
- Hydrodynamic models: Simulations of water flow impact on oysters.
- Oyster production: Cultivation and harvesting for consumption.
- Oyster populations: Groups of oysters in a specific habitat.
- Environmental parameters: Factors influencing oyster growth and survival.
- Active management: Interventions to restore and maintain oyster populations.
