28 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 22-08-2020.
A single shore entry dive Gary, Fran and Nevar of 230 minutes. Maximum depth 5.9 m, 20 C water temperature up to 10 m viz.
The beginning of the dive was supposed be a 1.6 m tidal flow and felt like a 2.0 m! Once it simmered down all was right. Finding 4 Knoutsodonta maugeansis was great - a real challenge to see the animals. Some species are really on the decline, most likely because the food sources are all gone and have not regrown. And of course finding Cerberilla always makes me smile...
