| Objective | The overall objectives of the program were to: Monitor the health and status of the B-MF fish community through annual sampling Assess long-term changes in fish community structure and correlate changes with environmental factors Report on icon site condition and provide information to guide management plans. Fish condition monitoring has been designed to assess the health and status of the fish community at 21 sampling sites distributed across two strata; permanent flowing (riverine) and semi-permanent flowing (creeks, lakes and wetlands) habitats. Fish condition is reported using community (abundance, biomass and fish species that are native) and population (recruitment, expectedness, size structure and distribution of native fish) indices. Each index and sub-indices were allocated scores from 0 (worst condition) to 1.0 (best condition) along with an associated grade (A to E) with a change in grade from the previous survey reflected as increasing (+) or decreasing (-). This report presents the results from the eleventh year of monitoring. We also present descriptive data for rare native species, Murray crayfish and riverine spawning of large-bodied species based on the objectives of the icon site. |
