Coastal aquaculture has emerged as a major sector for enhancing fish production by utilizing brackishwater and marine environments in a sustainable manner. A wide range of finfishes possessing fast growth, high market demand, tolerance to salinity variations, and suitability for captive rearing are considered commercially important for coastal culture. Among these, seabass (Lates calcarifer), mullets (Mugil cephalus and other Mugil species), milkfish (Chanos chanos), pearlspot (Etroplus suratensis), groupers (Epinephelus species), snappers (Lutjanus species), and cobia (Rachycentron canadum) are prominent candidates. Asian seabass, also known as barramundi, is one of the most widely cultured coastal finfishes due to its rapid growth, adaptability to a wide salinity range, and excellent flesh quality. The most promising method for its culture is pond and cage culture. In pond culture, earthen ponds are prepared by drying, liming, and fertilization, followed by stocking of hatchery-produced fingerlings. Semi-intensive systems with moderate stocking density, aeration, and supplementary feeding using formulated pellet feeds yield high production. Cage culture in coastal waters and estuaries is also popular, where seabass are reared in floating cages with regular feeding and monitoring, resulting in faster growth and efficient use of water resources. Mullets are hardy fishes that
