Species List: 17-12-2019, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

24 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld. 17-12-2019.

A single solo shore entry dive by Gary of 238 minutes. Maximum depth 5.6m, 24 C water temperature and up to 6 m viz.

Close to mid-week diving I decided to get into it! Upriver I went. Upon reaching the substrate there was a Colpodaspis sp. This dive was going to be special. Ten Colpodaspis sp. animals were recorded. Meanwhile five Costasiella sp. were recorded including two new species. The sand or as I put it "the desert" continues to be productive.
