PEMBERIAN PAKAN DENGAN KADAR PROTEIN YANG BERBEDA TERHADAP KELANGSUNGAN HIDUP DAN PERTUMBUHAN BENIH IKAN SEPAT MUTIARA (Trichogaster leeri)

Abstract

The research aims to determine the influence of the provision of feed with different levels of a protein to survival and growth seed Trichogaster leeri fish’s. The research was conducted in May - July 2015 at the Integrated Laboratory in Faculty of Fisheries and Marine Science, Bung Hatta University, Padang. Methods used in this research is his experiments with complete random design (CDR) 3 ways of treatment and 3 repetition. Treatment A (the feed artificially with levels of protein 30 %), treatment B (the feed artificially with levels of protein 35 %), treatment C (the feed artificially with levels of protein 40 %). The survival seed Trichogaster leeri fish’s the highest in treatment A (93.33 %), and followed with treatment B (90 %), the lowest was in treatment C (86.67 %). To the specific weight daily of the highest obtained at the treatment C with average (0.027 gr), followed treatment B with average (0.025 gr), and the lowest obtained at the treatment A with average (0.020 gr). The growth absolute weight is highest at treatment C (2,48 gr), followed treatment B (2.32 gr), and the lowest at treatment A (1.88 gr). At length specific daily highest acquired at treatment C with average (0.029 cm), and the lowest acquired at treatment A with average (0.023 cm). The growth of the absolute length of the seed Trichogaster leeri fish’s the highest in treatment C (2.64 cm), followed treatment B (2.32 cm), and the lowest treatment A (2.09 cm). Conversion feed the best found in treatment C (3,69 gr), and followed with treatment B (4.21 gr), the lowest is treatment A (5.39 %).
