Flashcards
0/15
Omnivores
Species that can feed on both plant and animal matter, thus they provide flexibility to the IMTA system by balancing trophic levels.
Suspension Feeders
Organisms that filter small particles out of the water column, improving water quality by reducing turbidity and utilizing suspended organics.
Waste Processing Facilities
Infrastructure designed for the collection, treatment, and conversion of aquaculture waste into usable products, such as fertilizers or animal feed ingredients.
Deposit Feeders
Benthic organisms that consume settled organic matter and remineralize waste; improves sediment quality and maintains benthic biodiversity.
Monitoring Systems
Equipment and protocols put in place for regular assessment of water quality, species health, and nutrient levels, ensuring the sustainability of the IMTA system.
Sediment Traps
Devices that capture organic matter falling to the ocean floor, reducing sedimentation and helping in waste management.
Recirculation Systems
Closed systems that filter and reuse water, conserving water and energy, while minimizing environmental impacts.
Finfish
Primary cultured species providing economic revenue; their waste nutrients are utilized by other species within the IMTA system.
Detritivores
Organisms that feed on dead organic materials and fecal matter, reducing the accumulation of organic matter and recycling nutrients.
Shellfish
Filter feeders that remove particulate waste and contribute to water clarity; they help in nutrient recycling by utilizing the waste from finfish.
Artificial Reefs
Structures placed on the sea floor to mimic characteristics of a natural reef; promotes biodiversity and provides habitat for various IMTA species.
Biofilters
Components such as certain bacteria that transform ammonia from waste into nitrite and then to nitrate, often through a process called nitrification, enhancing water quality.
Energy Generation Systems
Utilization of byproducts, such as methane from anaerobic digestion of waste, to produce renewable energy for the aquaculture operations.
Seaweed
Photosynthetic organisms that absorb dissolved nutrients for growth; they play a crucial role in nutrient recycling and water purification.
Herbivores
Species that consume plant material, including excess seaweed growth, which helps maintain a balanced ecosystem within the IMTA.
