Pearl Spot

The Pearl spot, Etroplus suratensis commonly known as “Karimeen” in Kerala is an indigenous fish extensively found along the east and south-west coasts of Peninsular India. It is an important candidate species for aquaculture in ponds in both brackishwater and freshwater environments. It is cultured in traditional ponds in Kerala where it is considered a delicacy fetching . Though growth is slow, at a high stocking density table-size fish can be harvested in 9-12 months culture period. Seed of pearl spot is available throughout the year along the east and south-west coasts of India. The peak season of abundance is during the months of May-July and November-February. It can be easily collected from both the brackish water and freshwater tanks and ponds. A simple method of seed collection is adopted taking advantage of the tendency of the fish to congregate in large numbers for feeding on epiphytic growth. In this method twigs or branches are kept submerged in the water a week ahead of day of collection. The juveniles congregating for feeding purpose are trapped using an encircling net or trap. Fecundity of pearl spot is low and has been estimated to be around 3000-6000; hence a successful hatchery production of seeds is difficult.
