Species List: 10-07-2019, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

18 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 10-07-2019.

A single shore entry dive by Gary and Sheryl of 131 minutes. Maximum depth 5.4 m, 21 C water temperature and up to 5 m viz.

Another beautiful winters day in paradise. The water temp was 21C this dive...where did that come from? This time Sheryl and I drifted upriver to the trees and descended. The vis in the river is clearing up and there were times when it was 5 m. There were a few species that were nice to find. Sitting on top of a small rock was a hydroid with 5 Tenellia sp. animals, this was Sheryls dream come true. Another good species to see again was Aglaja fulvipunctata, although these animals were quite small, about 4-5 mm. I find it amazing that the Pteraeolidia semperi numbers at the Toilet Block are high and here at Fish Cage quite low.
