Oriental Bonito

Oriental Bonito

Sarda orientalis

The Oriental Bonito occurs only in the waters of Western Australia (the Australian Bonito occurs on the east coast). It is a powerful and streamlined fish, often found in schools in the open sea up to 100m depth, where they are voracious predators of smaller fishes, squid and crustaceans. They are known to be found in schools with small tuna, and are suspected to be cannibalistic! Distinguished by narrow horizontal stripes on the upper and lower sides of the body, this blueish black fish can grow to 1 m in total length.

Occurrence at the Busselton Jetty

Whilst rarely seen from the Observatory windows due to their fast swimming nature, bonito are a prized catch for local fisherman during the summer and autumn.
