Green chromide

The green chromide (Etroplus suratensis) is a species of cichlid fish that is native to fresh and brackish water habitats in some parts in India such as Kerala, Goa, Chilika Lake in Odisha and Sri Lanka. The species was first described by Marcus Elieser Bloch in 1790.[2] Other common names include pearlspot cichlid,[1] banded pearlspot, and striped chromide.[3] In Kerala in India it is known locally as the karimeen.[4] In Goa the fish is known as kalundar.[5] In Odisha, the local name is kundal(କୁଣ୍ଡଳ ମାଛ). In Sri Lanka this fish is known as koraliya (කොරළියා).

Binomial name
Etroplus suratensis
(Bloch, 1790)

It has been introduced in various parts of the world outside its native range,[1] including Singapore, where it occurs in estuaries.[6]

This species and other members of the genus Etroplus are relatively closely related to the Paretroplus cichlids from Madagascar.[7]

Habitat and behavior

The green chromide lives in brackish water habitat types, such as river deltas. It eats mainly aquatic plants, including filamentous algae and diatoms, but it consumes the occasional mollusk and other animal matter. This species engages in attentive parental care in which several adults care for each brood.[1]

Appearance

The adult is oval in shape with a short snout. It is grey green with dark barring and a dark spot at the base of the pectoral fin.[1] It commonly reaches 20 cm (8 in) in length, and the maximum length is twice that.[2]

Relationship with humans

Etroplus suratensis is a popular food fish and it is considered a delicacy.[8]

Etroplus suratensis and E. maculatus form the main species and the former is dominant among pearl spots in reservoirs of India. They mainly feed on detritus and occupy the same niche as that of Oreochromis mossambicus. These fishes are very popular food fishes but their biomass is very low in reservoirs compared to other cichlids.[9]

In 2010 this species was named the official state fish of Kerala. The following year was declared "The Year of the Karimeen". Karimeen pollichatthu, a fried dish, is a delicacy served in restaurants. It is familiar to tourists, but because it is very expensive it is not easily accessible to poor folks. Production of the species for food is expected to increase in the near future.[4]
