Species List: 30-08-2020, Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

35 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 30-08-2020.

A single shore entry dive Gary, David, Harvey and Tracey of 254 minutes. Maximum depth 5.4 m, 19 C water temperature up to 8 m viz.

This mornings 1.3 m tidal flow with a 6 am high tide enticed us to enter the water at 3 am. We were enticed to go! The water clarity was great. Some very interesting species were recorded. The highlight for me was another new species for the river, Aplysia extraordiaria juvenile at 3 mm. We thought we would find another Pleurobranchus weberi! This animal had a chunk missing. With four of us this was another epic dive.
