Abstract

Goldfish (Carassius auratus) is a beautiful freshwater ornamental fish. Price of goldfish depends on several factors, one of them is the body color. Goldfish have stable price in the market whether market demand that continues to increase. Goldfish have characteristics from the type of colors and the beauty of their fins. Color is aesthetics ornamental fish that affect it economical values. Thus, the color should be upgraded and maintained its quality. Such efforts to increase color will be done by adding natural pigment into the feeds. Pigments natural resources can be obtained from Spirulina platensis. The purpose of this research is to know dosage Spirulina platensis that optimal to increase the color of Goldfish. This Research using Complete Random Design (CRD) with three repetition, with the dose treatment by 0 %, 1 %, 3 %, and 5 % for up during 28 days. Additional Spirulina platensis through the feed can increasing colors of the Goldfish. The nutrient that enriched with Spirulina platensis dosage 3% can produce colors brighter than the other dose. Additional Spirulina in the feed has no effect on growth of Goldfish.Keywords: Carassius auratus, Goldfish, Spirulina platensis, Color

Toba Lake is a lake that is used as aquaculture land. Floating net cage activities in the Toba Lake has been done by the public since 1986, but the rapid development of floating net cage occurred since 1998 through the intensive cultivation net high fish density. This study aims to analyze potential areas for floating net cage ini Toba Lake Girsang Sipangan Bolon, Simalungun by the suitability matrix method. This research use the scorring method/weighting. Determination of weighting and scoring is done to put a value on criteria that support the aquaculture activities by linking the chemical physical parameters. These parameters include temperature, DO, pH, brightness, current, depth, BOD, and ammonia. The results showed that the suitability grade in Toba Lake Girsang Sipangan Bolon is very suitable and suitable class. This shows that Toba Lake Girsang Sipangan Bolon is a potential area for floating net cage.Keyword : Toba Lake, Floating Net Cage, Suitability Index

Abstract

Greasy Grouper (E. tauvina) is a popular fish among Indonesian. Pest and disease of greasy grouper becomes one the most important factors of the success of the aquaculture of the Greasy Grouper. Greasy grouper with disease syimtomt were taken from Floating Net Cages (FNC) located in Belawan. This study aimed toobserve disease potential pathogenic bacteria,which infected the greasy grouper and was also foundin FNC. The study was conducted from May to August 2014 in SKIPM Laboratory of Class I Medan II. The isolation and characterization of the bacterial pathogen of the greasy grouper and FNC water was condacted using dilution methods. Three species of potential phatogenic bacteria were found i.e Aeromonas salmonicida, Edwardsiella ictaluri, and Vibrio harveyi.Keywords:Epinephelus tauvina, Floating Net Cages, Bacterial pathogens

Abstract

Bilih Fish (Mystacoleucus padangensis Bleeker) is fishing commodities in the Aek Alian River District Toba Samosir. Aek Alian River recently becomes a source of fish production Bilih Fish. The presence of this fish is could help the economy of people surrounding, but activities of catching uncontroled is one of the cause of decreasing of fish population. This Study has the objectives on accessing the growth and condition factor in the Aek Alian River. Research was conducted in May to Juni 2014. by using Purposive Sampling method. Stations spreaded among river with the station I (upstream), station II (midstream), and station III (estuaries). Primary data consisted of a total length and weight in individual fish of Bilih from the field. The sample number of Bilih fish were 281 individuals which consisted of 82 male and 199 female. The growth pattern (B) of Bilih fish is negative allometrict with value of B is 2.870 male and 2.868 female. The comparison of male and female is 1:2.427. Factor condition of Bilih fish shows 0.930 male and 0.942 female which means that the body of fish is bony or less fat.Keyword : Growth, Bilih fish resources, Mystacoleucus padangensis Bleeker, Aek Alian River

Abstract

Goldfish is the most desirable ornamental. The market demand required intensive cultivation. Intensive cultivation can be done by optimizing stocking density. This study aims to determine the effect of stocking density on survival and growth rate of goldfish (Carassius auratus) as well as to determine the maximum stocking density goldfish with an average length 4,16 cm and average weight 1,84 grams. The experimental design used was Completely Randomized Design (CRD) with three treatments is stocking density 1 fish / liter (P1), 2 fish / liter (P2), and 3 fish / liter (P3) and repeated 3 times. Treatment P1 shows the growth rate of weight daily and length growth rate that equal to the best daily is 2,75% and 0,87%. Stocking density significantly affect the growth rate of the long and weight growth rate daily but did not significantly affect survival. DMRT furthertest results indicate treatments P3 is significantly different from P1.Keywords: Carassius auratus, Goldfish, Growth Rate, Stocking Density, Survival Rate.

Abstract

Black ghost fish is a fish which is good economic value, both in the national and international scope. Market demand for the black ghost fish high, so it requires an effort to fulfill consumer demand for the black ghost fish. One of the efforts is to giving stimulation with thyroxine hormone into the commercial feed which is used for the growth of the black ghost fish. This research aims to determine the optimum dose of decent used for the growth and survival of black ghost fish optimally. The tested fish used are black ghost fish size of 6 cm which is maintained in an aquarium sized 60 cm×40 cm×40 cm by 13 units with water volume 24 liters per aquarium arranged randomly. The design which is used was a completely randomized design (CRD) with doses of without treatment, 10 mg/kg, 15 mg/kg, 20 mg/kg and 25 mg/kg. The results showed that the optimum dose which is good for the growth and survival of black ghost fish is 25 mg/kg, which is 4.36 cm long growing from the initial length and weight growth of 4.96 g of initial weight.Keywords: Black Ghost, Thyroxine, Growth, Survival Rate
