Abstract:
Catfish is one of the fish that is in demand for cultivation activities because it has high market
absorption, adequate nutrition, and is relatively easy to maintain. The research aims to
analyze the hematological response of Sangkuriang catfish (Clarias sp.) after being given a
feed substitute made from Duckweed flour (Lemna minor). The research was conducted in
Palangka Raya City, Central Kalimantan Province. Feed from each treatment A (Commercial
feed, feed without the addition of duckweed meal), B (Feed with 0% duckweed meal: 100%
soybeans), C (Feed with 50% duckweed meal: 50% soybeans), D (Feed with 75% duckweed
meal: 25% soybeans), and treatment E (Feed with 25% duckweed meal: 75% soybeans)
was weighed at 5% of each fish's weight in the treatment container. The hematological
response of Sangkuriang catfish given feed substitution made from Duckweed flour (Lemna
minor) with parameters of hematocrit, leukocrit, hemoglobin, and blood plasma of
Sangkuriang catfish for 45 days of research had a positive impact on fish health in this
condition due to the content of Duckweed flour (Lemna minor). can help control the health of
sangkuriang catfish.
