What do Barra eat?
Barra are fairly lazy opportunistic feeders they eat just about anything that lives in or around the water including prawns, small crabs, and even each other.
The size of the prey is largely determined by the size of the Barra.
A larger Barramundi’s diet consists of 60% fish and 40% crustaceans (mainly prawns), smaller barra eat mainly prawns.
This will vary according to where the fish is living.
How do Barra feed in dirty water?
Vision is probably limited in dirty water. Barramundi utilise what is called a lateral line, which is a sensory organ that runs down both sides of the body. The lateral line enables fish to detect vibrations in the water and so be able to locate prey and avoid predators. The question of whether it is the colour or action of the lure that attracts the fish is difficult to answer, however it is probably a combination of both.
