4.) Differentiate among freshwater, brackish water, and saltwater ecosystems.

•  Identifying chemical, geological, and physical features of aquatic ecosystems
5.) Relate geological and hydrological phenomena and fluid dynamics to aquatic systems.

6.) Explain the importance of biogeochemical cycles in an aquatic environment.

7.) Categorize aquaculture species as cold, cool, or warm water species.

8.) Determine important properties and content of water as related to aquaculture.

Examples: turbidity, pH, pollutants, dissolved oxygen, high specific heat, density, temperature

•  Describing the influence of water quality on aquaculture
Examples: aquatic plant control, water quality management, recognition and correction of oxygen deficiency, pH control

•  Identifying sources of aquatic pollution
Examples: point and nonpoint pollution, volcanic ash, waste disposal

•  Identifying biological concerns in a recirculating or closed system
10.) Describe infrastructure necessary for aquaculture production.

Examples: labor, feed manufacturing, transportation

11.) Identify the genotype and phenotype for specific characteristics in aquatic animals resulting from selective breeding.

Examples: disease-resistant fish, rapid maturation rates

•  Explaining the importance of anatomy and physiology in aquaculture
Examples: body systems, internal and external anatomy of fish, basic structure of an oyster

•  Calculating genotypic and phenotypic percentages and ratios for aquatic species
12.) Describe adaptations that allow organisms to exist in specific aquatic environments.

13.) Describe processes and environmental characteristics that affect growth rates of aquatic animals.

Examples: reproductive habits, feeding habits, interdependence of organisms, overcrowding, seasonal changes

•  Collecting aquatic growth-rate data

15.) Define concepts associated with health management of aquacrops.

16.) Describe the control of diseases and pests in aquatic environments.

Examples: pathogenic microspecies, parasites, predators, trash fish

•  Identifying the relationships among pathogen, environment, and host
