Survival Rate and Growth Performance of Catfish (Clarias sp) Seeds with the Addition of Serotonin Hormone

Abstract

The main problem faced in the supply of quality catfish seeds is the low survival and growth rates. The efforts that can be made to increase the survival rate of catfish and growth by administering the hormone serotonin. The purpose of this study was to evaluate the role and dose of the hormone serotonin on survival rates and growth performance in catfish fry. This study used RAL which consisted of 4 treatments with 3 replications namely the administration of serotonin hormone of 0 (S0), 0.1 (S1), 1.0 (S2), 1.5 (S3) mg/g-1 fish. The results showed that giving serotonin at 1.0 (S2) mg/g-1 fish was able to increase the survival rate of catfish seeds by 8.70% and inhibit growth performance by 13.86% in catfish seeds (Clarias sp).
