Species List: 31-01-2021, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld.

 22 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 31-01-2021.

A single shore entry dive with Harvey and Tracey of 200 minutes. Maximum depth 6.2 m, 27 C water temperature, up to 3 m viz. 

A morning high tidal flow, lots of eddies on the surface and the water looked great. On floating to the start of the dive we realised the current was still quite strong, and as we descended, we confirmed both surface and subsurface current was still running solid, so we made our way back to the side and waited. On the second descent, the current was still flowing but more manageable.

On sight the landscape was sand blasted with no silt. The number of species was low and taking photos was a challenge. The sand was bare of life. Despite that on we went and found the usual suspects, with three different species of Gymnodoris which was very cool.  On approach to Fish Cage we spotted a large long familiar object, not a new species unfortunately but a nice carbon fishing rod!. We removed it along with a large fist of line, hooks and sinkers.
