Mugil amarulus Valenciennes, 1936, Mugil kelaartii Günther, 1861, and Mugil longimanus Günther, 1861 are synonyms of Moolgarda perusii (Valenciennes, 1836) according to Eschmeyer (CofF ver Jan. 2013: Ref. 92887).
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; catadromous (Ref. 26213); depth range 0 - 3 m (Ref. 86942). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm 15.1  range ? - ? cm
Max length : 41.0 cm TL male/unsexed; (Ref. 30573); common length : 25.0 cm TL male/unsexed; (Ref. 30573)
(total): 4 - 5;
soft rays: 9. Color greenish-grey dorsally, sides silvery. Second dorsal and anal fin with black margins (Ref. 9812). Posterior tip of upper jaw hidden when mouth closed. Pectoral fins 86-97% of head length, reaching below origin of first dorsal fin with axillary scale nearly half the length of fin. 37-43 scales in lateral series, scales with membranous digitated hind margin.
Occur in shallow coastal waters, including estuaries and backwaters, frequently enters freshwater. Form larger aggregations during spawning which takes place at sea. Young individuals enter tidal rivers. Feed on organic matter contained in sand and mud (Ref. 30573). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Marketed fresh and salted. Decays rapidly, but well liked when fresh.
