Abstract

The addition of Bacillus polymyxa bacteria in the feed as immunostimulant is one of the efforts of disease prevention on vannamei shrimp (Litopenaeus vannamei). The aimed of this research was to know the effectivity of the use of Bacillus polymyxa bacteria in feed towards the non-specific imunity of vannamei shrimp. This research consisted of 4 treatments namely feed with the density of Bacillus polymyxa bacteria 0 cell/ml as control (A), 104 cell/ml (B), 106 cell/ml (C) and 108 cell/ml (D) and each treatment is repeated 3 times. This research has been done in 15 days. Parameters that observed this research were total haemocyte count (THC), phagocytosis activity, differential haemocyte count (DHC) and water quality. The results showed that the addition Bacillus polymyxa bacteria of 106 cell/ml was able to improve THC value 6,6x107 cell/ml on the day 10. The DHC value was in the normal range which is hyalin cell was 52-89% and granular cell was 11-48%. The quality of water maintenance media during this research was in the normal range there were temperature 27,2-28,1°C, DO 3,70-3,91ppm, pH 3,70-3,91, and salinity 30-35 ppt.

Abstract

Way Pegadungan is a tributary of Way Seputih, has a length of 35.31 km and a river width of 50 to 70 meters. Way Pegadungan is very potential for aquaculture but has not been used optimally. This research was held in March - May 2018 using a descriptive quantitative method aimed at assessing the level of suitability of the waters by knowing the physical and chemical parameters for the cultivation of betutu fish. The data used primary data, namely the parameters of water suitability in the form of water quality values, while the secondary data is in the form of research location maps. Water suitability analysis was carried out using matching and scoring methods. The range of data obtained is depth: 6-7 m, brightness: 37,5-55 cm, temperature: 28-29ºC, pH: 7-8,21, dissolved oxygen: 4,02-6,73 mg / l, current : 0,14-0,16 m / s, nitrate: 0,16-0,21 mg / l, phosphate: 0,01-0,025 mg / l, ammonia: 0,01-0,065 mg / l, organic matter: 6,7-10,76 mg / l. Sampling stations were 4 stations determined by the global positioning system (GPS). At the first and fourth points get moderately sutable  (S2) and at the second and third points get marginal sutable (S3).

Abstract

In vaname shrimp cultivation, one of the problem that often arise is the high production costs in provision of feed The use of probiotics is a viable alternative to reduce production costs. The probiotic that used in this research was Bacillus coagulans bacteria. This research was aimed to know the effect of the use of Bacillus coagulans bacteria in feed on weight growth, lenght growth, survival rate, feed conversion ratio, and water quality in cultivation on vaname shrimp. Post larvae 10 vaname shrimp as much as 25 pcs were placed in each aquariums with volume 50x40x40 cmfor 30 days. The probiotics with dosage of treatment 30 ml/kg; 50 ml/kg; 70 ml/kg were combined in commercial feed with the protein content 32%. The shrimp feeding method that used in this research was blind feeding with 4 times feeding a day. The result showed that the best treatment was 70 ml/kg feed giving the significant effect on weight growth, length growth, andfeed conversion ratio. The treatments didn't effect on SR however. The water quality such as DO, temperature, salinity, and was TAN still in the optimum value.

Abstract

Liquid waste produced by tofu and tapioca industry was approximately 1,5-2 m3 and 4-6 m3 per day respectively. Tapioca liquid waste has concentration of carbon around 119,11 mg/l, while tofu liquid waste has around 133,03 mg/l of nitrogen in concentration. Therefore both of these waste have the potential to be used as biofloc that utilized as additional feed with high protein content for nile tilapia. The aim of this research was to know interaction between C/N ratio and place of biofloc production to the growth of nile tilapia. This research used completely randomized design based on factorial experiment which consisted of two level of each factor and three repetition. Level of C/N ratio were 15 and 20 whereas level of place of biofloc production were inside and outside fish culture container. The result of this research showed that interaction between place of biofloc production and C/N ratio affected the growth of nile tilapia. The treatment inside biofloc production with 20 C/N ratio gave provided the highest absolute growth (3,26 g) and daily growth rate (0,082 g per day).

Abstract

Guppy is one of the most popular ornamental fish. In some ornamental fish, colour of aquarium can enhance the fish colour intensity. The research aims to determine the effect of different aquarium colour on Guppy colour intensity which maintenance on semi outdoor. The research was used completely Randomized Design (CRD) with 4 treatments and 3 replications (maintenance guppy in colourless aquarium, black coloured aquarium, yellow coloured aquarium, silver coloured aquarium). The Guppy fish used is 60 days old that kept on aquarium 30 cm x 20 cm x 30 cm and the water volume is 4 liters/aquarium. Research was conducted for 40 days, fish amount is 8 fish/aquarium. Colour intensity data were analyzed by using ANOVA and the significantly different results followed by a further test of Least Significant Difference (LSD). Observed parameters were the colour intensity, pH, and temperature. The results showed that maintenance Guppy fish under different colour of aquarium gave the effect on Guppy colour intensity, the best effecton colour intensity Guppy fish show at the colourless aquarium.

Abstract

The cost of feed is one of the production costs that account for 65%, so the need for alternative feed ingredients that can reduce feed costs. Lemna plant has good enough nutrition as alternative food such as protein 32,13%, nitrogen extract (BETN) 15,96%, and fat 5,13%, crude fiber 28,58% and ash 18, 20% that can be used as fish feed ingredients.The aim of this study is to determine the effect and the best dose level of fermented lemna flour to the level of feed utilization, growth and survival of dumbo catfish (C. gariepinus).The experimental fish used was juvenile of catfishwith an average individual body weight of 3,43±0,06 g and the density of 1 fish/2 l for 42 days. This experimental applied completely randomized design (CRD), which consisted of 5 treatments and 3 replicates. The treatments were treatment each by an addition of flour lemna fermented 0% (A), 5% (B), 10% (C), 15% (D) and 20% (E) respectively. The results showed that the flour lemna fermented provided significantly effect (P<0,05) on total feed comsumption, feed utilization effeciency), protein efficiency ratio and relative growth rate. However, no significant effects (P>0,05) wereoccured on the values of survival rate. The highest dose of 20% dose of fermented lemon flour resulted in total feed intake of 170.01 ± 9.25 g, feed efficiency of 78.82 ± 4.75%, protein efficiency ratio of 2.49 ± 0.15% and the relative growth rate (of 4.60 ± 0.31% / day, while the optimum dose of fermented lemon flour to total feed consumption, the efficiency of feed utilization protein efficiency ratio and relative growth rate have not found the optimum point because based on orthogonal polynomial test still patterned linear.

Abstract

Feed is the main source of nutrients to support vannamei shrimp growth. The high cost of feed in operational costs due to the high raw material price of fish meal, limited availability, while the demand is high. Therefore it is necessary to find alternative materials that are low in price, have a high enough protein content and abundant availability such as golden snail flour. The purpose of this study was to analyze the effect of different proportion of fish meal and mashed snail (Pomacea canaliculata) as the main feedstock for the growth of shrimp vannamei (Litopenaeus vannamei). The experimental design used in this study was Completely Randomized Design (RAL) consisting of 5 treatments, namely A (57.18% use of fish meal in feed), B (42.89% use of fish meal, 14.30% mashed flour), C (28.59% fish meal usage, 28.59% mashed snail), D (Use of 14.30% fish meal, 42.89% mashed snail), and E (Use 57.18% golden snail flours). This study shows that the addition of mashed snail flour in the feed can increase the growth of absolute weight, the daily weight of vannamei shrimp, and can decrease the value of FCR.
