Aquaculture is the practice of farming aquatic organisms, including fish, shellfish, and plants, in controlled environments such as tanks, ponds, or ocean pens. This method of farming provides a reliable and sustainable source of seafood, offering a solution to the growing global demand for fish and other marine products. It reduces the pressure on wild fish populations, helping to preserve natural ecosystems.

Poultry farming is the practice of raising birds like chickens, turkeys, ducks, and geese for meat, eggs, and feathers. It is a major source of protein for people worldwide. There are two main types: broiler production (raising chickens for meat) and layer production (raising hens for eggs). Modern poultry farming uses controlled environments, special feed, and advanced breeding to increase production efficiency.

Veterinary medicine is the field focused on preventing, diagnosing, treating, and managing diseases and injuries in animals. Veterinarians ensure the health of pets, livestock, wildlife, and research animals. Their work includes specialties like small animal care (pets), large animal care (livestock), exotic animal care, and public health, where they help control diseases that can spread from animals to humans.
