Fish farming can utilize either seawater or freshwater, with freshwater sources including rivers, lakes, and ponds.

The farming of shellfish such as prawns and molluscs is often referred to as mariculture or shellfish aquaculture.

Fish farming helps meet the growing demand for fish protein by providing a consistent and controlled supply of fish, thus contributing to food security and accessibility, particularly in regions where access to wild-caught fish is limited.

The two main methods are capture fishing, which involves harvesting fish from natural resources, and fish farming, also known as aquaculture or culture fishery.

Nutritional deficiencies can lead to various health problems, poor growth, reduced egg production, and decreased immune function in poultry fowl, ultimately affecting their overall productivity and profitability.
