The Effect of Different Ratios of Internal Organs, Dried Artemia and Frozen Artemia on the Growth Rates of Common Carp Fish

Abstract

A total of 140 fish with an average weight of 35±2 grams were used and reared for a period of 70 days. The fish were randomly distributed into seven treatments, which included the addition of dried Artemia to the second, third, and fourth treatments at a ratio of 50% of fishmeal. The internal organs powder of the fish was added to the third and fourth treatments at a ratio of 25% and 50% of fishmeal respectively. Frozen Artemia was added to the fifth, sixth, and seventh treatments at a ratio of 50% of fishmeal, and the internal organs powder of the fish was added to the sixth and seventh treatments at a ratio of 25% and 50% of fishmeal respectively. The results showed that the arithmetic mean of the sixth treatment was superior to all other treatments, reaching 82.80 grams/fish. This treatment included the addition of 50% frozen Artemia, 25% fish powder, and 25% internal organs powder. Furthermore, the results showed that the lowest weight gain rate for the fish was in the fourth treatment (51.40 grams/fish), which included the addition of 50% dried Artemia and 50% internal organs powder to the common carp fish feed. In conclusion, the addition of frozen Artemia at a ratio of 50% of fishmeal, enhanced with 25% internal organs powder, was found to be the best among the treatments in terms of growth criteria.
