(Sea catfishes) > Ariinae
Etymology: Arius: Greek, arios, areios = dealing with Mars, warlike, bellicose (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; potamodromous (Ref. 51243); depth range 50 - 100 m (Ref. 28016), usually - m (Ref. ). Tropical; 0°C - ; 33°N - 4°S
Indo-West Pacific: off the west and east coast of India, Sri Lanka, Pakistan, Bangladesh, Myanmar to the Arafura Sea (Ref. 9819) and the Indo-Australian Archipelago (excluding Australia). Known from the Mekong Delta (Ref. 12693).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 38 - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 11441); common length : 30.0 cm TL male/unsexed; (Ref. 3290)
Adults occurs in inshore waters and estuaries. Occasionally form schools. Feed on invertebrates and small fishes. Males incubate eggs in the mouth (Ref. 205). Caught mainly with set bag nets and bamboo stake traps. Marketed fresh (Ref. 3290). Air bladders are exported as isinglass used by the wine industry (Ref. 43081). Strong venomous dorsal and pectoral spines provide protection for the fish (Ref. 43081).
Males incubate eggs in buccal cavity. During incubation, males starve which sometimes make them resort to swallowing one or two eggs probably to maintain basal metabolism (Ref. 43081). Early hatching embryos commence feeding on inhaled particles by the female when still in possession of large yolk.
