Major disaster this morning in the Tilapia Hatchery. Water levels in the outside 1 kl went lower than the bubbler leaving fish starved for oxygen. Sadly these fish are now contributing their nutrients to the compost heap. Perhaps I lost half the fish, there are still many quite healthy. I also lost two gold fish that had become quite big in the tank.
I have now changed the bubbler set up in such a way that it can never be exposed above the water level. But the system is being tweaked and adjusted with every mistake I make. I have made a lot of mistakes!
