Abstract

The objectives for this research are to know the effects of immunostimulants and optimal doses to increase the growth of white snapper fish. This research was conducted from August 25, 2018 until September 27, 2018 in the Laboratory of Brackish Water at the Fisheries Faculty of Pekalongan University. The methods used was the Completely Randomized Design Method consisting of 4 treatments and 3 replications. The given is artificial feed which mixed with differents doses of imunostimulant, treatment consist of A (0 ml/kg feed), Treatment B (5 ml/kg feed), Treatment C (10 ml/kg feed) and Treatment D (15 ml/kg feed). The seeds of white snapper fish are used for this research with size 4-5 cm and the density of 1 fish per liter. The parameters observed were biom ass growth, daily specific growth rate (%), ratio of the amount of feed needed, efficiency of feed utilization (%), degree of life (%) and the water quality as supporting data. The research results showed that the given immunostimulant on the feed had an effects on the growth of white snapper fish, Calculated F (13,474) > F Table 5% (4,066) and the F Table 1% (7,591). The use of immunostimulant give the highest results on the biomass growth of white snapper fish on the Treatment D of 9,13 gram, FCR 0,92, EPP 42.86 %, SGR 3,31 %, and SR 100%. The water quality during the research showed that the temperature range from 28 - 30 C, pH range is 7.0 – 7,4, Dissolved Oxygen range is 5.2 – 7.2 ppm, Salinity range is 32 – 35 ppt and Ammoniac range is 0.1 – 0.3 ppm.

Abstract

The purpose of this study was to determine the effect of adding vitamin C in artificial feed and the optimum dose to the growth of snakehead fish seeds. The research method used was a completely randomized design with 4 treatments and 3 replications. The treatments used were: A (giving vitamin C at a dose of 50 mg/kg of feed), B (giving vitamin C at a dose of 100 mg/kg of feed), C (giving vitamin C at a dose of 150 mg/kg of feed), D ( giving vitamin C at a dose of 200 mg/kg of feed). The results showed that the highest average biomass growth was obtained in treatment D with a dose of vitamin C 200 mg/kg of feed, the increase in biomass reached 3.04 grams. While the lowest growth was obtained in treatment A with a dose of vitamin C 50 mg/kg of feed resulting in an average growth of 1.09 grams. The results of the analysis of variance on the growth of snakehead fish seed biomass showed that the calculated F value was greater than F table 1% and 5%. The range of water temperature during the study was between 27 -30 o C, water pH ranged from 7.4-7.6 and dissolved oxygen in water (DO) ranged from 4.2-4.9 mg/l. Keywords: snakehead , vitamin C, growth

Abstract

Shrimp vannamei (Litopenaeus vannamei) is a kind of shrimp that has important economic value in Indonesia, one of the inhibiting factors in increasing shrimp production is a disease caused by bacteria vibrio sp. This disease can cause a high death. This study aims to identify and quantify the number of Vibrio sp bacteria colonies in the hepatopancreas shrimp vannamei in ponds given probiotics, carried out in Sampang Tigo Ponds, Degayu –Pekalongan and Central Fish Ponds Brackish Water Aquaculture (BBPBAP), Jepara. This study was conducted on Monday 13 November 2017 to Wednesday April 25 2018. The study was conducted on a pond with a density of 100 and 116 tail / m3. The data of the research results were analyzed descriptively with the help of graphs and tables. The results showed that the sample of each plot of bacterial colonies exceeded the threshold, that is the average number of vibrio sp bacterial colonies on hepatopancreas shrimp T2 3,96 x 10 6 CFU/ml and T3 plots 1,46 x 10 6 CFU/ml followed by shrimp morphological changes that have clinical signs of vibrio sp bacteria, the state of unbalanced water quality supports the bacterialgrowth.
