After the big seas this week the lagoon is in trouble. Normally sea water washing into the system refreshes it, bringing in oxygen and nutrients for the fish. This time however a huge mass of kelp washed in, sand closed the lagoon mouth, and the water has become anaerobic. We noticed it early this morning when we saw large bream struggling in the shallow water nearest to the outlet. They were hoping the sea would rush in again and free them, so they could swim back to the ocean. By coincidence it was a water-testing morning (first Sunday of each month) and the test results showed zero percentage of oxygen! So we mounted a fish rescue.
There were six of us, with buckets and nets, catching all the fish we could, transporting them across the sand to the sea, where they recovered quickly and swam away into the waves. After we had caught as many large fish as we could we concentrated on the small fry, taking perhaps a thousand little fish to the ocean. Even so we are afraid we will see dead fish floating tomorrow morning, unless heavy rain or big seas bring change.
