Aquaponics – First fish introduced

After a week of cycling the system, planting a few veggies and tuning the timing of flood and drain to each of the grow beds I am just about to introduce 35 colourless goldfish.

As we are in the midst of winter at the moment with the water temperature getting down to 8 degrees C over night, I thought it best to use a very hardy fish to get the whole system going. In December I will introduce a combination of Silver Perch and native Catfish. Apparently they both do very well in a both cold and warmer water once they reach a decent size, so they should over winter well next year.

I’ve had the bags floating in my fingerling tank with an aerator inserted for about an hour, to equalize the water temperature. Now to add some water from the fish tank into each bag and then release them in about half an hour. So far so good.

Keep tuned for further updates.

    It sounds like it’s going well and you sure have done the research to know how to make it all work!

    • Thanks Nancy. So far so good. I just hope I don’t wake up tomorrow and find fish floating belly up in my fingerling fish tank. The goldfish are renowned for being pretty tough so fingers crossed. Now that I have fish in the system, their waste will kick start the whole process of bacterial development in the grow beds that will convert the ammonia to nitrates that will feed the plants. I’m told that it will happen slowly so I must be patient and hope that everything survives the process. If all goes to plan then I should be harvesting organic veggies within six to eight weeks and then there will be no stopping me. The aim is to not just become a little more self sufficient but to inspire others to do the same.
