[3] Very similar in appearance to Murray cod and eastern freshwater cod , they are striking looking, golden-yellow to dark green or brown, deep-bodied fish with dark green to black ...

In New South Wales, sand whiting have a minimum legal length of 27 cm to be taken and a daily personal bag limit of 20 applies, [34] while in Queensland there is a minimum size of 23 cm and a combined bag limit of 30 for all whiting species. [35]
The legal size in Australia varies by state, from 35 cm (14 in) and a bag limit of five fish per person in Queensland to 50 cm (20 in) in Western Australia. During spawning, these fish obtain a metallic green sheen which indicates a high concentration of acid buildup within the scales' infrastructure.
This and catch data and computer modelling exercises [16] on wild Murray cod stocks indicate measures such as raising the size limit to 70 centimetres and reducing the bag and possession limits from 2 and 4 fish respectively to 1 fish are urgently needed to maintain the long-term viability of wild Murray cod populations. As of November 2014 ...
The golden perch (Macquaria ambigua) is a medium-sized, yellow or gold-coloured species of Australian freshwater fish found primarily in the Murray-Darling River system, though a subspecies is found in the Lake Eyre-Cooper Creek system, and another subspecies, suspected to be ancestral to all other populations, is found in the Fitzroy River system in Queensland.

A slot limit is a tool used by fisheries managers to regulate the size of fish that can legally be harvested from particular bodies of water. Usually set by state fish and game departments, the protected slot limit prohibits the harvest of fish where the lengths, measured from the snout to the end of the tail, fall within the protected interval.

The southern black bream is protected by size and bag limits in all the states it inhabits, which anglers must be aware of or face fines. In Western Australia the size limit is 25 cm with only 2 fish over 40 cm allowed to be taken from the Swan or Canning Rivers, while the bag limit varies throughout the state with West Coast allowing 4 per ...
