Aquatic environments encompass a range of ecosystems, from freshwater lakes and rivers to expansive marine habitats like oceans and coral reefs. These environments each have unique properties, such as variations in salinity, light availability, and nutrient content, that determine which species can thrive within them. Freshwater environments are home to fish like tilapia and trout, while saltwater habitats support species such as shrimp and seaweed. In aquaculture, understanding these distinctions is key to selecting and raising species in conditions that mimic their natural habitats. Sustainable management of these environments ensures not only the health of farmed species but also the conservation of the broader ecosystem.
