Which species is commonly raised in aquaculture?

Salmon is commonly raised in aquaculture due to its high market demand, nutritional value, and adaptability to farming conditions. Fish farming often targets species that have a proven track record in captivity and can grow quickly to harvest size. Salmon, particularly species like Atlantic salmon, has been extensively studied and successfully cultivated, making it a staple in aquaculture.

In contrast, species like penguins, turtles, and crocodiles are not typically raised in aquaculture for several reasons. Penguins are wild birds with complex social structures and specific habitat needs that make them unsuitable for farming. Turtles, while sometimes raised in certain cultural contexts, face significant challenges in aquaculture due to their long growth cycles and specific habitat requirements. Crocodiles may be farmed in some regions for their skin and meat, but they are less common in mainstream aquaculture compared to fish like salmon. Thus, the extensive practices, economic viability, and consumer preference distinctly position salmon as a leading species in aquaculture.
