Brine Shrimp

Fish

Brine shrimp, Artemia species, have been used successfully for years as a food for aquarium fishes. the eggs of Artemia are noted for their viability, and they have been packaged and sold throughout the world, ready for hatching and feeding to small fishes of all species. Many claim that there is no better food for newborn fishes, and the authors are inclined to agree with this school of thought.

The use of newly hatched brine shrimp as a first food for fishes has several advantages:

  • They are easily hatched and available at the time they are needed
  • Secondly, since they are a marine form they do not carry fresh-water parasites or other organisms which might be harmful to baby fishes
  • Thirdly, they are so small that even if they are overfed to the baby fishes they will not use up much oxygen should they live in the fresh water, nor will they cloud the water if they should succumb.

Of late there has been made available to aquarists the frozen form of the adult Artemia. Larger fishes greedily take these but, like frozen Daphnia they seem to lose much of their food value once they have been frozen. the organism does not remain intact when frozen, but bursts its ectoskeleton and there really is nothing left for the fishes to feed upon except empty shells.
