30 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 28-05-2020.

A single shore entry dive by Gary, Sheryl, Tracey and Harvey of 212 minutes, Tracey and Harvey went north. Maximum depth 5.4 m, 21 C water temperature up to 7 m viz.

With the dredger gone it is time to finally dive Fish Cage to see what damage has been done. To my surprise the actual Fish Cage with still there untouched. There were parts of the substrate where huge damage was done....sad. Despite that we did manage to record 30 species. Brilliant. Finding Facelina sp. was great. The numbers of Unidentia are amazing!! There were many Goniodoridella sp. 1 to be seen as well. And to top it 2 species of Myja were found. I gotta tell you the dives are getting hot.
