Life Cycle
provided by Fishbase
Spawns in shallow water above grassflats on the falling tide. Investigation of sexual identity of large samples suggest the species is gonochoristic (sex-reversal do not occur), the first sparid species known to be so (Ref. 1875). Also Ref. 103751.

Trophic Strategy

Occurs inshore (Ref. 75154). Inhabits seagrass areas or areas with hard substrates heavy with algal cover (Ref. 30573). Present in seagrass beds at all life stages (Ref. 41878). Feeds on seagrasses and algae (Ref. 30573). Inhaca Island is a seagrass epibiont so it is possible that its ingestion of sponge and unidentified Hydrozoa are unintentional along with the seagrass (Ref. 42227). In Nakagusuku Bay, Okinawa Island, all larvae ranging from 1.0-1.5 cm SL, fed only on planktonic copepods. Food shifted from planktonic copepods in postflexion larvae and juvenile ranging from 1.0-1.5 cm SL to seaweed in the juvenile ranging from 1.5-2.5 cm SL (Ref. 54487). Food shifts in adult and young over 2.5 cm SL to feed almost exclusively on drifting Sargassum spp. (Ref. 54487).

Found in sheltered bays, harbors and lagoons (Ref. 48636). Inhabits seagrass areas or areas with hard substrates heavy with algal cover. Usually occur in small groups. Unlike other parrotfishes, males and females look very similar and do not change sex (Ref. 48636). Feeds on seagrasses and algae (Ref. 30573). Marketed fresh (Ref. 5284).

Marbled parrotfish
provided by wikipedia EN
The marbled parrotfish (Leptoscarus vaigiensis), also known as the seagrass parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae and is the only known member of the genus Leptoscarus. It has a wide Indo-Pacific distribution and is also found in the southeastern Atlantic Ocean. It is a coastal species found in beds of sea grass and seaweed.
Description
The marbled parrotfish is brown to green with darker mottling on the back fading to yellow or greenish ventrally. The males are marked with a pale longitudinal strip along their flanks and the head, body, dorsal fin and anal fin are marked with small blue spots. The females are mottled brown and white.[3] On the head the females have broad bands which radiate from the eyes.[4] This species has 9 spines and 10 soft rays in the dorsal fin while the anal fin has 3 spines and 9 soft rays and there are 13 rays in the pectoral fin. The distinctive narrow dental plates are fused into a parrot-like beak and are covered in numerous small teeth.[2] When its mouth is closed the upper jaw teeth are enclosed by the lower jaw.[3] This species can attain a maximum total length of 35 cm (14 in).[2]
Distribution
The marbled parrotfish has a wide Indo-Pacific distribution from the northern Red Sea south along the eastern coast of Africa to the Cape of Good Hope and eastwards through the Indian Ocean and Pacific Ocean to Easter Island. In the Pacific Ocean its range extends north to Japan and south to Rottnest Island off Western Australia and the Poor Knights Islands of New Zealand.[2] In the southeastern Atlantic this species is found in False Bay in the Western Cape, South Africa.[1] Its distribution is largely anti-equatorial (i.e., found in both the Southern and Northern Hemispheres, but rare or absent near the Equator).[5]
Habitat and biology
The marbled parrotfish lives in sheltered bays, harbours and lagoons among seagrass beds and algal-covered reefs.[6] It normally occurs in small groups.[2] It ranges in depth from 0–15 metres (0–49 ft).[7] Uniquely among parrotfish, females never change sex to males;[5] they are gonochoristic. Spawning occurs in shallow water over flat seagrass beds on the ebbing tide. As well as being gonochoristic, marbled parrotfish also show less sexual dimorphism than most other parrotfishes. Their diet consists of sea grass and algae.[2] The larvae of the marbled parrotfish are associated with drifting algae.[1]
Naming and taxonomy
The marbled parrotfish was first formally described as Scarus vaigiensis in 1824 by the French naval surgeons and naturalists Jean René Constant Quoy (1790–1869) and Joseph Paul Gaimard (1793-1858) in their book Voyage autour du monde. The type locality was given as Waigeo.[8] William John Swainson created the genus Leptoscarus in 1839 and L. viagiensis is the only species in this monospecific genus.[9]
Human usage
The marbled parrotfish is caught in local artisanal fisheries and it is normally marketed fresh.[1] In Queensland there is a limit of 5 marbled parrotfishes in a maximum bag of 20 coral reef fishes and they must be no less than 25 centimetres (9.8 in) long.[4]
