Manatee (Trichechidae)
The family Trichechidae, commonly known as manatees, belongs to the order Sirenia. These large aquatic mammals are strictly herbivorous, consuming vast amounts of submerged and emergent vegetation, which significantly impacts the aquatic environment in their habitats.

Manatee (Trichechidae)
From an agronomical perspective, while manatees are not typical pests of terrestrial crops, they act as biological agents affecting irrigation infrastructure. They inhabit canals and waterways, consuming vegetation that can either clear blockages or destabilize the structural integrity of channel banks.
The biology of manatees is centered around their high metabolic demand for aquatic plants. They graze on seagrasses, water hyacinths, and other vegetation throughout the day. Their reproductive rate is notably slow, which limits population growth and requires careful management and environmental protection.
The damage caused by manatees is primarily related to the physical disruption of irrigation flow. By consuming vegetation, they can inadvertently contribute to soil erosion along canal banks and potentially block irrigation intake valves or filters, affecting the efficiency of agricultural water delivery.
Protection strategies involve the installation of non-lethal deterrents and physical exclusion barriers. Since manatees are often classified as protected species, management focuses on preventing their entry into sensitive irrigation systems rather than eradication, ensuring both agricultural stability and animal conservation.
