mnat said:We don't feed the brine anything and feed them to the fish when they are small. Brine shrimp are like popcorn, fish love to eat it but they have almost no nutrional value. When they are smaller, they will have more nutrional value, so that is the best time to use them as food. We also add vitamin C to the culture to give them a bit more.
Exactly... it's actually the park of the embryo casing that provides the nutritional value. The only reason to grow them any larger would be for a larger fish that needs to be transitioned from live food. This becomes more difficult and requires additional cultures.
