South Australia is responsible for nearly 70% of the national catch of gar.
Southern Sea Garfish (Hyporhamphus melanochir) are distributed from Shark Bay in Western Australia, along the southern coast of Australia including Tasmanian waters, and as far east as Eden in New South Wales. The species forms schools in sheltered bays and shallow, inshore, marine waters to depths of ~20 m. They are particularly abundant throughout the gulf regions of South Australia.
Southern Garfish have an extended spawning season that spans approximately six months from October to March. Within this season only a small proportion (10–20%) of the population are in spawning condition at any given time indicating that reproductive activity is asynchronous with small pulses of spawning activity. The estimated size at maturity (L50%) for female Southern Garfish in South Australia is 215 mm TL, which is equivalent to the mean age of 17.5 months.
Typically, Southern Garfish is found in the seagrass and weed of sheltered bays. Northern Spencer and Gulf St Vincent are the key producing regions during peak supply.
