Abstract
This study aims to determine the growth of catfish (Clarias sp.) Seeds by giving a combination of silkworms (Tubifex sp.) and commercial feed. This research was conducted in August - October 2020 in the fish farming group of PT ASABRI, West Ilir II Palembang, South Sumatera. The treatments used in this study were 100% silkworm (control) feeding and a combination of feed treatment consisting of 75% commercial feed and 25% silkworms. Parameters include absolute weight growth, absolute length growth, feed efficiency, survival, and water quality. The results obtained from this study indicate that combination feeding (P1) obtained better results than the control (P0) with absolute weight growth data of 8.38 g, absolute length 7.39 cm, feed efficiency 56.38% and survival 87.50%.Keywords: catfish, commercial feed, combination, growth silkworm
Highlights
This study aims to determine the growth of catfish (Clarias sp.) Seeds by giving a combination of silkworms (Tubifex sp.) and commercial feed
Feed used for seed catfish include natural feed and commercial feed
According to Amanta et al, (2015), a combination of artificial feed and natural feed in order to create a balance of amino acids in the body of fish seeds, because amino acids come from animal and vegetable protein which will meet the amino acid needs needed by catfish seeds
Summary
The tools used in this study include an aquarium with a size of 60 x 30 x 60 cm, an aerator, an aeration hose, an aeration stone, a scale, a sipon hose, a thermometer and a pH meter. While the materials used include catfish seeds with a size of 3 cm, fresh silk worms, potassium permanganate, and commercial feed with a protein content of 40%
