The purpose of this research is to determine the effect of liquid commercial probiotics usage on improving the survival rate and growth of Siamese catfish fingerlings. This research was conducted on March to May 2018, at Building 4 Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This study used an experimental method with Completely Randomized Design (CRD), which consisted of four treatments and three replications. The treatments are feed without the addition of probiotics, and feed with additional probiotics at doses of 2, 4, and 6 ml / kg of feed. The parameters observed were survival rate, absolute weight, absolute length, feed conversion ratio, proximate test analysis and water quality. Data on absolute weight, absolute length, feed conversion ratio and survival rate were analyzed using analysis of variance, while nutrition changes of fish feed and water quality were analyzed descriptively. The results showed that the best addition of probiotics for feed, is with probiotic doses of 2 ml / kg of feed, which resulted in a 100% survival rate, an absolute weight value of 1.03% and a feed conversion ratio of 1.13.

The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1 , 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.

The Purpose of this Study is to comprehend and compare the quickness of astaxanthin and canthaxanthin in improving ranchu goldfish color. The ability of carotenoids to be digested and absorbed depends on the structure. Carotenoids that quickly improve color quality are desirable. In this work, goldfish were fed one to three diets for 30 days to determine the effects of astaxanthin and canthaxanthin on color enhancing, growth and survival rate. The experiment consisted of (A) an unsupplemented control, (B) astaxanthin (carophyll pink 100 mg / kg), and (C) canthaxanthin (carophyll red at 100 mg/kg). Samples of dorsal skin were observed and measured via TOCA Color Finder (TCF) each day. The best colour result was obtained by canthaxanthin, but our work revealed that growth and survival rates are not significantly different among the groups.

This study aims to see the condition of hematocrit levels and differential leukosit after immersion in LAB isolated and after in vivo, using Aeromonas hydrophila bacterium. LAB isolated were obtained from the organs of the common carp intestine. The study used a Completely Randomized Design (RAL) consisting of four treatments and three replications. The treatment used was immersion of test fish for 24 hours in several isolates of LAB with a density of 108, namely A: without LAB isolate (control), B: isolate CcB7, C: isolate CcB8, D: isolate CcB15. Immersion was done three times, with a frequency of seven days. Parameters observed included hematocrit levels, leukocyte differentiation and survival rate. The results showed that immersion in LAB isolate CcB15 will enhance the differential leukocytes and hematocrit levels that serve as indicators of carp body resistance, which is shown by high levels of white and red blood cells.

This study was conducted to determine the effect of probiotic addition in commercial feed to the growth and survival rate of Sangkuriang catfish (Clarias gariepinus). This research was conducted at the Ciparanje Experimental Pond Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor, West Java. The method in used this research was Completely Randomized Design with four treatments and four replications. The treatment was the variances of probiotic addition which consisted of control (without probiotics), probiotic addition at as much as 0.5 grams / kg of feed, 1 gram / kg of feed and 1.5 grams / kg of feed. The parameters observed were specific growth rate (SGR), absolute biomass, survival rate (SR) and feed conversion ratio (FCR). Data were analyzed using Variant Analysis, at 95% confidence level, and continued with Duncan's Multiple Range Test. The results showed that the increase in the daily growth rate of Sangkuriang catfish was straight-line with the addition of probiotics. Furthermore, commercial probiotics with a dose of 1 gram / kg of feed resulted in specific growth rate of 4.22%, absolute weight of 11 grams, survival rate (SR) of 97.5% and FCR of 0.89.
