Population age structure of Murray cod indicates a large recruitment event 1 year in 5, demonstrated by a cohort representing >50% of the population. Did a YOY cohort represent >50% of the Murray cod population from the Gorge zone?3,4,5,6 Did the length-frequency distribution for Murray cod indicate at least 1 large recruitment event in the last 5 years, demonstrated by a YOY cohort6 representing >50% of the population from the Gorge zone? 3,4 Abundance (CPUE) of Murray cod increases by ≥50% over a 10-year period. Did the abundance of Murray cod in the Gorge zone increase by ≥20% over a 5-year period?3,7 Restore resilient populations of golden and silver perch specialists). Abundance (CPUE) of golden perch and silver perch increases by ≥30% over a 5-year period. Did the abundance of golden perch in the Gorge zone increase by >30% over a 5-year period? Did the abundance of silver perch in the Gorge zone increase by >30% over a period? 3 Restore resilient populations of freshwater catfish. Abundance (CPUE) of freshwater catfish increases by ≥30% over a 5-year period. Did the abundance of freshwater catfish in the Gorge zone increase by ≥30% over a 5-year period? 3 Restore and maintain resilient populations of foraging generalists (e.g. Australian smelt, bony herring, Murray rainbowfish, unspecked hardyhead, carp gudgeons, flathead gudgeons). The length-frequency distributions for foraging generalists include size classes showing annual recruitment.
