  • Acclimation: The process of gradually adapting post-larvae or fingerlings to the water conditions (temperature, salinity, pH) of their new pond.

  • Additive (Feed): A substance added to feed to improve nutrition, palatability, preservation, or health (e.g., vitamins, probiotics, pigments).

  • Aeration: The process of introducing oxygen (air) into the water to maintain adequate DO (Dissolved Oxygen) levels.

  • Aerator: Mechanical equipment (e.g., paddlewheel, impeller, blower, diffuser) that promotes aeration.

  • Aerobic: A biological process that requires the presence of free oxygen.

  • Aflatoxin: A toxic compound produced by molds (Aspergillus) that can contaminate feed ingredients (like corn or soy), causing liver damage and poor growth.

  • Algae: A diverse group of aquatic photosynthetic organisms, including microalgae (phytoplankton) and macroalgae (seaweed).

  • Alkalinity: The water's capacity to neutralize acids. It acts as a "buffer" that prevents sudden fluctuations in pH.

  • Ammonia (Total and Toxic): A nitrogenous compound (NH₃/NH₄⁺) excreted by animals and resulting from the decomposition of organic matter. The NH₃ form (toxic ammonia) is lethal.

  • Anaerobic: A biological process that occurs in the absence of oxygen.

  • Antibiotic: A drug used to treat bacterial infections. Its use must be careful and under veterinary prescription.

  • Antiparasitic: A drug used to treat infestations by parasites (external or internal).

  • Aquaculture: The farming of aquatic organisms (fish, shrimp, mollusks, algae) in captivity.

  • ASC (Aquaculture Stewardship Council): A major international certification seal for responsible aquaculture.

  • Autotrophic: A system (like a "green water" system) where primary production (phytoplankton) forms the basis of the food web.

  • Automatic Feeder: Equipment that dispenses feed at programmed times and quantities, optimizing feeding management.
