Species List: 19-11-2020, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

37 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 19-11-2020.

A single shore entry night dive Gary, Chris, Fran, Nevar and David of 207 minutes. Maximum depth 5.5 m, 24 C water temperature, .5 - 5 m viz.

With a 1.3 m tidal flow a night dive was in order. The winds were none and the we arrived at the site the river was like a lake. I was very excited to see when we first got to the bottom the water was pretty dirty maybe a half meter or more, as the tidal flow picked up it clear to about 5 m. Bubble shells were out in force! Seven Colinatys sp. 1 and seven Mnestia sp. 1 were great to see. According to David who spent most of the dive up high said there were many Bulla quoyii and Bull vernicosa showing up with the UV light. Chris recorded two Thordisa tahala and two pale Dendrodoris nigra...welcome back! Congrats to Nevars first night dive!
