26 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 24-06-2020.

A single shore entry dive by Gary, Tracey and Harvey of 240 minutes. Maximum depth 5.6 m, 19 C water temperature up to 8 m viz.

More river madness. The winter time is truely here. 10 C air temp, 19 C water temp like a warm bath! Batteries all charged then I got to the bottom, turned everything on, fired a test shot then the light-ring died! Used Solalight for light go dive...not the best shots but there's a record. For me the highlight was turning over a small rock seeing an bryozoan with eggs masses and 4 Knoutsodonta maugeansis, WOW! The second Tornatina sp. 7 shell was recorded today as well. The numbers of Cratena lineata were so low I didn't think I'd see any. 2 species of Costasiella were really nice to find! Plus this the first dive this winter in 19 c water temp. Over the past 3 years 19 C has been the lowest.
