Species List: 12-02-2019, Fish Cage up river, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

12 species sighted at Fish Cage up river, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 12-02-2019.

A single shore entry dive by Gary, Gail and Adele of 204 minutes. Maximum depth 5.8 m, 28 C water temperature and 5+ m viz.

I thought we might try Fish Cage up river again to see it diversity had improved. The first half of the dive was really scarce as far as differnt species goes. Maybe the 28C water temp has caused the decline. The sandy areas are really silt covered. However the hydroids have been productive. The golden hydroids have returned to the Fish Cage and one Tenellia sibogae was sighted.
