A beautiful was here and the river looked inviting. After entering the water my nose started to run and I sneezed a bit, meanwhile my nose was running and was so uncomfortable I had to abort. Here is my short story...

27 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 11-07-2020.

A single shore entry dive by Gary, Fran, Nevar, Tracey and Harvey of 210 minutes. Maximum depth 5.2 m, 20 C water temperature up to 6 m viz.

Today the river was smooth and no wind so nice. Finding several Kabeiro christianae with their vertical egg masses was a treat. A couple of Myja sp. 1 were found as well. A highlight for me was turning over a small rock and finding Pleurobranchaea maculata, the second animal ever recorded here. 2 Pruvotfolia sp. 1 with egg masses were also a treat. A new record for this diverse river area was recorded today as well, Cerberilla affinis our 414th species for the river. Well done Team!
