  • Farm: The entire operational unit, including ponds, canals, and infrastructure, for aquaculture production.

  • Feed: Balanced food (in nutrients, vitamins, minerals) formulated and processed to meet the requirements of each species and stage.

  • Feed Conversion Ratio (FCR): The ratio of the amount of feed given to the weight gain obtained (kg of feed / kg of biomass gain). It is a key efficiency indicator.

  • Feed Tray: A submerged tray used to monitor shrimp feed consumption and adjust the feeding rate.

  • Feeding Rate: The amount of feed provided per day, usually expressed as a percentage of the biomass (e.g., 3% of biomass).

  • Fertilization: The addition of fertilizers (chemical or organic) to the water to stimulate phytoplankton growth (primary productivity).

  • Filter Feeder: An animal (like mollusks or even tilapia) that feeds by filtering particles from the water (plankton, flocs).

  • Fingerling: A young fish, past the fry stage and ready for stocking into grow-out ponds.

  • Fishmeal: A high-quality protein ingredient traditionally used in aquafeeds.

  • Flash-test (or Jar-test): A lab or field test to simulate and evaluate flocculation, settling, or the need for liming.

  • Flocs (Microbial): Aggregates of bacteria, algae, protozoans, and organic matter that form the basis of the biofloc system.

  • Formalin (Formaldehyde): A chemical used (under regulation) as a treatment against ectoparasites.

  • Fouling: The accumulation of unwanted organisms (like algae, barnacles) on submerged structures (cages, screens, sensors).

  • Fry: The earliest stage of a fish after hatching and absorbing its yolk sac.
