Abstract

Addition of Sargassum sp. into feed as a feed supplement is one effort that can be done to increase fish growth and immunity. This research aims to determine the effect of adding bioactive compounds from Sargassum sp. extract in feed on the health picture of Siamese catfish through structural changes that occur in the intestines and liver. Fish observations were carried out for 40 days. The results obtained regarding the survival rate (SR) value of Siamese catfish seeds show that there is no difference or has the same percentage, namely 100%. The results of observations on the histopathology of intestinal organs analyzed in a comparative descriptive manner showed that Siamese catfish fry were fed with Sargassum sp. extract experienced damage than fish seeds fed without the addition of Sargassum sp. extract (control). The damage that occurs includes leukocyte infiltration (IfL), necrosis (Ne), goblet cell proliferation (Psg), hyperplasia (Hpl), and hemorrhage, with a damage score analyzed using the semiquantitative scoring method, namely 1. Damage to the liver, namely experiencing congestion in the blood vessels.

Abstract

Feed additives or feed additives are now starting to become a necessity as additional feed in fish feed that can increase fish growth. This research aims to determine the effect of using clove powder as a feed additive in feed on the growth rate and survival rate of red tilapia fingerlings. The research was carried out at the Aquaculture Laboratory Building 4, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor from June to August 2023. The research method used is an experimental method using a complete randomized design consisting of four treatments and four repeats. The treatment used is the use of clove powder at doses of 0% (control), 0.5%, 1%, and 1.5% as feed additives in commercial feed. The observation parameters consist of specific growth rate, survival rate, and water quality. The results showed that the use of clove powder as a feed additive in commercial feed with a dose of 0.5-1.5% tended to increase the growth rate of red tilapia fry with specific growth rate values ranging from 1.17 ± 0.30%/day - 1.27 ± 0.12%/day. The survival rate of red tilapia fry with a dose of clove powder use of 1.5% tended to give the best results (97.50 ± 5.00%). The water quality of red tilapia fry maintenance during the study met the requirements of water quality standards for tilapia farming
