The growth in the value of NSW aquaculture in 2021-22 was largely driven by the continuing increase in land-based aquaculture, up 17% year-on-year and up 146% over the past 10-years. Whilst there is a variety of aquaculture production systems used to culture aquaculture species, NSW has large areas suitable for land-based aquaculture with access to high quality surface water, ground water, estuarine and marine waters. Land-based facilities culture finfish, crustaceans, algae and ornamental species in earthen and lined ponds, tanks and aquaria.
Increases in Murray Cod and Black Tiger Prawn production has underpinned the growth in land-based aquaculture. Historically, commercial Murray Cod hatcheries focused on producing cod fingerlings for stocking into rivers, farm dams and impoundments. These stockings were traditionally used as a method of increasing wild populations while enhancing recreational fishing. However, significant investment has occurred in the industry in recent years and backed by the NSW Government Land Based Aquaculture Strategy, production has soared, with the value of Murray Cod increasing from $4.3 million in 2017-18 to $14.8 million in 2022-23. The iconic fish has become highly marketable over the past few years, and domestically, is fast becoming a fine dining staple.
Oysters remained by far the largest aquaculture sector, contributing 56% of the total aquaculture value (Incl spat). Production remained relatively steady year-on-year however there was a slight increase in the price received per dozen, particularly for Pacific Oysters.
