School shark (2499 words)
School shark catches peaked in 1969 and were still high at the end of the 1980s, but by then the fishing effort required to take this catch was 3 times that in the late 1960s. An assessment of the southern shark stocks (school shark and gummy shark ) at a workshop in October 1991 indicated that the adult population of school sharks is very depleted in parts of Bass Strait and gummy sharks are probably moderately overfished also. School shark and gummy shark stocks are also adversely affected by other fisheries such as trawling, offshore longlining, the bay-and-inlet fisheries in Victoria, Danish seining and the recreational fishery in Tasmania where specialised gillnets are used.

School and gummy sharks live over the continental shelf and slope from shallow estuaries to depths of 400 meters. School and gummy shark were first sold as flake from the Melbourne Wholesale Fish Market in the late 1920's to serve a booming Fish 'n' Chip trade. The proportion of school shark in the total catch is expected to decline as fishers stop targeting this species.
