  • Food habits / trophic level : in South Africa, between 10 mm and 50 mm SL the juveniles feed on zooplankton, amphipods, chironomid larvae, tanaids and small crabs.

In Beachwood Creek (Mgeni Estuary) juvenile (< 100 mm SL) showed a positive selection for amphipods, tanaids and fish scales, with polychaetes, ostracods, gastropods and aquatic plants also being consumed .

  • Reproduction : in South Africa, spawning by specimens greater than 17 cm SL occurs in the KwaZulu-Natal nearshore marine environment and estuary mouths, mainly from May to August. In the Kosi Estuary mouth region, spawning was recorded at night and timed to coincide with the ebb tidal transport of eggs out to sea. Egg and early larval development take place at sea, with 0+ juveniles entering KwaZulu-Natal estuaries at approximately 10- 30 mm SL, mainly between July and November .
