Effects of percentage of aquarium cover on light illumination in influencing growth patterns of Pangasius sp. seeds

Abstract

This study aims to see the effect of differences in light illumination on the growth pattern of seed catfish (Pangasius sp). The experimental design used in this study was a completely randomized design (RAL) with 4 light illumination treatments and 3 replications. The parameters measured in this study were the daily growth rate and growth pattern of seed catfish. The difference in light illumination tested in the study had an influence on the daily growth rate of seed catfish (Pangasius sp). with the best treatment in this study from treatment A namely by providing light illumination of 11 lx provides the best daily growth rate of 5,9 % and continues to increase every week. The growth pattern of the length and weight of a relationship is negative allometric where the value (b) and the determinant coefficient value is lower than 3 which means that the growth of fish seed length affects the body weight gain of seed catfish.
