Biologie     Verklarende woordenlijst (b.v. epibenthic)

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).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

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.
