Aquaculture - AP Environmental Science

Vaccination is a method to manage disease in aquaculture. Prevents disease outbreaks that can devastate farm populations.

Mariculture is aquaculture practiced in marine environments. Saltwater farming that utilizes ocean and coastal environments.

Stocking density is the number of organisms per unit area or volume. Higher densities can reduce growth rates and increase stress.

Seaweed is used for food and biofuel production. Valuable for nutrition, pharmaceuticals, and renewable energy.

Implementing waste management systems reduces impacts. Proper treatment prevents nutrient pollution and ecosystem damage.

RAS is a closed-loop system that filters and reuses water. Maximizes water efficiency and controls environmental conditions.

RAS minimizes water use and waste discharge. Enables year-round production with controlled water parameters.

Disease management is a challenge faced by aquaculture. Dense populations increase disease transmission and treatment costs.

Pond culture is a method of aquaculture. Uses controlled water bodies for fish cultivation and management.

Phytoplankton provide a primary food source in aquaculture systems. Form the base of aquatic food webs and oxygen production.

Overfeeding can lead to water pollution and waste. Excess feed decomposes, depleting oxygen and releasing toxins.

Disease management is a challenge faced by aquaculture. Dense populations increase disease transmission and treatment costs.

Pond aquaculture is practiced in freshwater environments. Utilizes natural or artificial ponds for fish cultivation.

Antibiotic resistance is the main concern. Overuse creates resistant bacteria that threaten human health.

Genetic contamination is a potential negative impact. Escaped farmed fish may interbreed with wild populations.

Using plant-based feeds is a sustainable practice. Reduces dependence on wild fish for feed production.

Dissolved oxygen is crucial for the respiration of aquatic organisms. Essential for cellular respiration and metabolic processes.

Recirculating aquaculture system (RAS) is practiced in tanks. Provides controlled environment with water filtration and reuse.

FCR measures the efficiency of converting feed into biomass. Lower FCR indicates more efficient and profitable operations.

Tilapia is a common species cultivated in aquaculture. Hardy, fast-growing fish ideal for farming in various environments.

Polyculture is cultivating multiple species in the same environment. Maximizes space efficiency and can improve water quality.

Oysters are commonly farmed shellfish. Filter feeders that improve water quality while growing.

Atlantic salmon is commonly used in marine aquaculture. High-value species widely farmed in net pens globally.

Cage culture is a type of freshwater aquaculture. Uses enclosed nets suspended in ponds or lakes.

Seaweed is used for food and biofuel production. Valuable for nutrition, pharmaceuticals, and renewable energy.

Implementing waste management systems reduces impacts. Proper treatment prevents nutrient pollution and ecosystem damage.

Fishmeal is a protein-rich feed made from fish. Ground fish used as primary protein source in aquaculture feeds.

The main purpose is to produce food and resources like fish, shellfish, and seaweed. Meets global protein demand while reducing pressure on wild fisheries.

Hatcheries produce juvenile fish for aquaculture operations. Ensures consistent supply and genetic quality for farming operations.
