ການອ້າງອີງຫຼັກ	Hickley, P. and R.G. Bailey, 1987
ຂໍ້ສັງເກດ	Post-larval B. bajad feed on copepods (Ref. 27490). Small fish (immature) take a mixed food of organic detritus, crustaceans and fish (Ref. 51638). Adults feed on insects, fish and plants (Ref. 6160), crustaceans and molluscs (Ref. 28714), or are exclusively piscivorous (Ref. 31256). In small specimens the percentage of insects declines with increasing body size, while that of shrimps increases; for individuals larger than 24cm the trends reverse (Ref. 33614). Lives and feeds on or near the bottom (Ref. 3034, Ref. 33614). Avoids salt water (Ref. 31439).
