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

Abstract

This research aims to determine the optimal dose of chitosan that is appropriate to be given to commercial feed in increasing the immune system of sangkuriang catfish fry. The research was carried out in April – June 2021 at the Aquaculture Laboratory and Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University. This research used an experimental method of Completely Randomized Design (CRD) with five treatments and three replications. The treatment used was the addition of chitosan to feed with doses of 0 g (A), 2.5 g (B), 5 g (C), 7.5 g (D), and 10 g (E). Maintenance of test fish for 14 days. Experimental fish were infected by Aeromonas hydrophila bacteria with a density of 108 CFU/ml with 10 ml immersion method. Parameters observed included white blood cells, leukocyte differential, clinical symptoms, survival and water quality. Data on white blood cell count, and survival were analyzed by ANOVA, if there was a significant difference, Duncan's test was performed. Leukocyte differential data, clinical symptoms and water quality were analyzed descriptively. The results showed that the addition of chitosan at a dose of 10 g was effective for improving the immune system performance of catfish fry. During 14 days of chitosan administration, the white blood cell count increased by 41.60% from the value of 13.96 × 104 cells/mm3 to 23.90 × 104 cells/mm3. The 10 g chitosan treatment was an effective dose to stimulate differential leukocytes in catfish to improve the immune system, it was also marked by the fastest clinical symptom recovery period and the highest survival rate after the challenge test, which was 96.6%.

Abstract

The purpose of this study is to determine the influence and determine the optimal dose of moringa leaf extract and kencur in feed on the growth performance of catfish seeds. This research was carried out at the Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences Padjadjaran University from February to March 2024. Sampling in this study used an experimental method using a Complete Random Design (RAL), the growth data obtained was analyzed using the analysis of the F test variety fingerprint (ANOVA / Analysis of Varience) and for the water quality data was analyzed descriptively. The results of this study, namely the addition of 150 mg/kg of moringa leaf extract and 250 mg/kg of kencur extract to feed had an effect on improving the growth performance of catfish seeds which was more optimal than other treatments, as shown by an increase in the percentage of absolute length growth (4.2 cm), absolute weight (57.58 g), SGR (3.80%), FCR (1.44%), EPP (68.90%), and SR (100%). The water quality values during fish rearing are in the optimal range including temperature (27.5-28.3°C), pH (7.0-7.5), and DO (5.2-7.5 mg/L).
