Study Notes
- Aquaculture cultivates aquatic organisms like fish, crustaceans, molluscs, and aquatic plants in controlled settings.
- It occurs in freshwater, brackish water, and marine water environments.
- The goal of aquaculture is to boost aquatic species production for consumption, recreation, and stock rebuilding.
- Sustainable aquaculture emphasizes reducing environmental harm, conserving resources, and ensuring lasting operations.
- Responsible resource use, waste control, and biodiversity protection are key to sustainable aquaculture.
- Integrated Multi-Trophic Aquaculture (IMTA) grows multiple species from different trophic levels together for sustainability.
- IMTA lessens waste and enhances output by using one species' byproducts as inputs for another.
- Species selection for aquaculture considers biological, environmental, and market factors to pick suitable aquatic organisms.
- Growth rate, disease resistance, environmental tolerance, and market demand are important selection criteria.
- Native species are often favored to lower the chance of introducing invasive species and harming local ecosystems.
- Maintaining water quality is crucial for the health and productivity of aquaculture systems.
- Temperature, salinity, dissolved oxygen, pH, ammonia, and nitrate levels are key water quality indicators.
- Aeration, water exchange, and filtration are crucial for monitoring and controlling water quality.
- Recirculating Aquaculture Systems (RAS) recycle water in closed loops, cutting water use and environmental effects.
- RAS uses mechanical and biological filters to eliminate waste and keep water clean.
- Feed composition significantly affects the growth, health, and nutritional value of cultured aquatic species.
- Aquaculture feeds typically have protein, carbs, lipids, vitamins, and minerals.
- Sustainable feed options use plant-based proteins, insect meal, and algae to decrease reliance on fishmeal.
- Aquaculture's economic effects include creating jobs, generating income, and improving food security.
- Aquaculture can offer income for coastal communities and boost local economies.
- The economic feasibility of aquaculture farms is influenced by market demand, production costs, and regulations.
- Aquaculture genetics studies genetic traits in aquatic species to improve output and quality.
- Selective breeding seeks to improve desirable traits like growth rate, disease resistance, and meat quality.
- Genetic modification methods like gene editing and transgenesis are employed to create superior aquaculture strains.
- Managing disease is vital for preventing outbreaks in aquaculture systems.
- Disinfection and quarantine are biosecurity measures used to lower the risk of disease introduction and spread.
- Vaccines and immunostimulants are used to boost cultured species' immunity.
- Regulations and certifications ensure aquaculture operations meet environmental and social standards.
- Best Management Practices (BMPs) and Aquaculture Stewardship Council (ASC) certifications encourage responsible aquaculture.
- Aquaculture is a rapidly growing sector that could greatly improve global food security and economic growth.
- Following sustainable aquaculture practices helps minimize environmental effects and ensure the sector's future.
- Open aquaculture systems need water exchange.
- Filter feeders help filter and purify water in aquaculture systems.
- Carbon sequestration can help to reduce carbon emissions.
- Polyculture, or species diversity, results in greater stability.
- Probiotics enhance the immune system and gut microbiome of aquaculture species, preventing diseases.
- The economic success of aquaculture farms depends on species, system design, and farm administration.
- Disease outbreaks can cause significant monetary losses in aquaculture.
- Meeting regulatory standards and obtaining certifications is important for market access and consumer confidence.
- Site selection involves assessing land availability and ease of access to infrastructure.
