Species List: 31-12-2019, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

25 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 31-12-2019.

A single shore entry dive by Gary, Fran, and Nevar of 175 minutes. Maximum depth 6.2 m, 26 C water temperature and up to 5 m viz.

The last day of 2019 and a new species Trapania aurata was found in the river,  hoping one day it would be found. Numbers of species has dropped  ff and I wonder if because of the silt thickness and maybe food sources dwindling has anything to do with it.
