البيئة
بحري; المياه العذبة; مياه مخلوطة القاع; مهاجرة بين الياه الملحه و الحلوة لكن ليس للتزاوج (Ref. 51037). Tropical

الحجم / وزن / العمر
Maturity: Lm ? range ? - ? cm
Max length : 18.0 cm SL ذكر/ مختلط الجنس; (Ref. 12693)
الأشواك الظهرية (المجموع) : 7; الأشعة الظهرية الناعمة (المجموع) : 10 - 11; شوكة شرجية: 1; أشعه شرجية لينه: 10 - 12. Scales on predorsal midline 13-20, usually 15-18; scales in horizontal series 46 to 51, usually 48-49; breast scaled; belly anteriorly with small naked patch next to pelvic base (Ref. 34009).
Occurs inshore (Ref. 4343) and enters brackish and fresh water along the upper tidal zone of rivers (Ref. 12693). Larvae spend time in the marine zooplankton and as juveniles, about 135 days old, recruit to freshwater streams where they undergo rapid growth and morphological changes neceassary for upstream migration to the adult habitat (Ref. 51037). Marketed fresh in mixed catches (Ref. 12693).
