Resumen
Descripción
Aquaculture has emerged as a prominent sector contributing to global nutritional security. It has been recording a growth rate of over 5 percent per year in recent decades. Asia contributes nearly 90 percent of global aquaculture production. Indian major carps (IMCs), cultured primarily in polyculture, are the dominant farmed species in South Asia, with 75 percent produced in India. The majority of this output comes from three species of IMCs: catla (Catla catla), rohu (Labeo rohita) and (Cirrhinus mrigala). These three species occupy mutually compatible ecological niches within water bodies and are grown together in specific ratios; this optimally harnesses pond biological resources. The IMCs are consumed domestically and are a key to national nutritional security.
