2020/21 Common Jack Mackerel Status (Released Dec 22)

Summary Common Jack Mackerel is a predominantly Commonwealth-managed species that has been classified as “Not overfished nor subject to overfishing” by ABARES in the Fishery Status Reports 2021 (Patterson et al. 2021). Only minor catches of this species have been taken from Tasmanian waters over the last decade due to one purse seine operator leaving the fishery. Patterns of catch and effort are unlikely to reflect stock status but the currently low level of fishing pressure in Tasmania is unlikely to cause the stock to become recruitment impaired.

Common Jack Mackerel is a schooling species that inhabits open water over the continental shelf from southern Queensland to Shark Bay, Western Australia, including Tasmania. Jack Mackerel are mainly targeted using purse seine and beach seine gear. The Jack Mackerel fishery in Tasmania peaked in 1986/87 with a catch > 40,000 t (Kailola et al. 1993). However, by 2000 surface schools were less available in Tasmanian waters and fishers began midwater trawling in Commonwealth waters. There was another, smaller peak in the Tasmanian commercial fishery in 2008/09 due to a sharp increase in purse seine effort. However, since then both catch and effort have been low. There is a small recreational fishery for Jack Mackerel using line gear in Tasmania.
