Inland Restricted Fishery
The Inland Restricted Fishery is a small commercial fishery that operates primarily in the waters of the Murray-Darling, targeting carp and yabbies only. Commercial fishers catch yabbies using "Opera House" yabby traps fitted with by-catch reduction devices. Carp are caught most commonly using hauling nets and meshing nets, however fyke nets, pound nets, traps and electro-fishing are sometimes used, with all methods subject to stringent permit conditions to prevent by-catch of native species.
