  1. why the varying amount of feed from week 19 to 30?

    1. This is what is recommended by the manufacturers of the commercial food we use. We use a brand Guabi, which is sold in South America. However, we also supplement with duckweed. We feed ours pellet food, one day, and duckweed the next.

    2. Can you please tell me what size is the fish in 30weeks

    3. At 30 weeks your tilapia should be weighing just over a kilo. This of course is a rough guide and yours may be smaller or larger.

    1. We had both some tilapia in tanks where there was a water exchange system in place and also in cages in a lake. The lakes had no water exchange system. It was rain fed.

  3. One more question if you don't mind, in the case where they are to get 12 feeds per day, do you split it into 1 hour time spans where you would start at, say for example, 6 am and end at 6 pm? if this is the case then does this 12 hour feeding period get split evenly as the number of feeds decreases?

    1. I am sorry for the late reply. Unfortunately I can't answer your question as we bought our fish in at 30-50grams.

      However, yes I would assume that is how it works because the fish won't feed at night unless it is lit with either lights or with moonlight.
      We always had an early morning feed and fed the last one about 5 or 5:30 in the early evening.
      However we live only 4° south of the equator so our days are pretty much the same year round.

  4. What feed conversion, do you get with this chart?

  5. How much cost per kg is the fish food

    1. Hi Yassir,
      The price we were paying, was R$43 (Brazilian reals) for a 25 kg sack. We bought it in bulk though.
      However, there are different qualities. There is even one which is a higher protein.
      The price will vary depending on your location, the brand and the quality.

  6. Could you please let me know that How much protein content has to be there in feed?

  7. If you are buying a commercial feed, there will be different protein levels at the various stages of growth. When they are small and being fed powder, the protein levels could be 55%. At various stages of growth it may vary from 22% to 36%. Remember in a good quality commercial feed, it is a balanced diet and provides the fish with minerals and vitamins needed for optimal growth in the shortest time possible.

  8. Amin Bakari from Tanzania
    How much do you sell your fish from your project?

  9. How much do you sell fish from your project?

    1. We sell locally for R$5.00 a kilo. That is to our local store. For our big buyer who comes in once a year, he pays a different price depending on the weight but will take as many as we can pull out. Above 800grams R$3.80, and the price went down for the smaller fish.

  10. i did not get the no of feeds per day? are you saying spiting the feeds as 12 times per day ?
