Barramundi

Life of Sea | Barramundi  |  The barramundi (Lates calcarifer), also known as Asian seabass, is a species of catadromous fish in family Latidae of order Perciformes. It is known as koduva in the Tamil language, kalaanji in Malayalam language, pandugappa in the Telugu language in India, bhetki in the Bengali language in eastern India and Chonak in the Konkani language in Goa in western India.
Scientific classification
Kingdom:Animalia
Phylum:Chordata
Class:Actinopterygii
Order:Aulopiformes
Family:Paralepididae
Barramundi is a loanword from an Australian Aboriginal language of the Rockhampton area in Queensland meaning "large-scaled river fish". . The single dorsal and ventral fins have spines and soft rays; the paired pectoral and pelvic fins have soft rays only; and the caudal fin has soft rays and is truncate and rounded. Barramundi are salt and freshwater sportfish, targeted by many.
The barramundi feeds on crustaceans, molluscs, and smaller fish (including its own species); juveniles feed on zooplankton. The barramundi is euryhaline, but stenothermal. It inhabits rivers and descends to estuaries and tidal flats to spawn. In areas remote from freshwater, purely marine populations may become established. At the start of the monsoon, males migrate downriver to meet females, which lay very large numbers of eggs (several millions each).
 The adults do not guard the eggs or the fry, which require brackish water to develop. The species is sequentially hermaphroditic, with most individuals maturing as males and becoming female after at least one spawning season; most of the larger specimens are therefore female. Fish held in captivity sometimes demonstrate features atypical of fish in the wild: they change sex at a smaller size, exhibit a higher proportion of protogyny and some males do not undergo sexual inversion
