Abstract

Fluctuating asymmetry of the bilateral meristic characteristic is one of the simple methods that can be used to determine the stability of an individual fish development. This study aims to provide quantitative information about the level of asymmetry of Nile tilapia (Oreochromis niloticus) in Dunia Air Independent Training Center Marine and Fisheries, Banyuwangi through bilateral meristic characteristic observation.  A total of 120 fish samples (5-7 cm) were measured in this study. Four bilateral meristic characters were calculated i.e. the number of soft pectoral fins, number of soft ventral fins, number of scales on the lateral line up and down. The results show that the highest value of the fluctuating asymmetry of magnitude (FAm) and fluctuating asymmetry of number (FAn) was obtained at the number of scales on the lateral line up those are 2.14 and 0.78, respectively. Meanwhile, the lowest FAm and FAn values obtained from the soft ventral fins which were 1.69 and 0.78, respectively. The sum of the total value of fluctuating asymmetry of each bilateral meristic characteristic was observed. The overall FAm value was 7.83 and the overall FAn value was 2.99.Keywords: fluctuating asymmetry, Nile tilapia, PMKP Dunia Air

Abstract

Asymmetric fluctuations function as a measure of organ stability in pairs in an individual. This study aims to determine the value of asymmetric fluctuations in hybrid grouper hybrid fish from Situbondo and Bali. The study was conducted for 3 months, starting from July-September 2018. The grouper used in this study was 100 individuals from each region, with a size of 7-9 cm. Bilateral meristic characters measured include the pectoral fin, ventral fin and lateral line. The results showed that the ventral fin character of the grouper fish from Situbondo and Bali had a higher FA value of 0.6-0.7, while the lateral linea organ had a higher FAm value, 1.1 to 1.9. The FAgb value of the grouper originating from Situbondo has a high value compared to the grouper from Bali, which is 1.5-2.4.

Abstract

Detriment caused by ectoparasitic infestation was not as big detriment caused by infestation of other organisms such as viruses and bacteria, but it could be a predisposing factor for the infection of more dangerous pathogenic in fish. The aims of this study was to inventory ectoparasites that infecting freshwater fish cultivated in several districts in the Banyuwangi, in which the results were expected to be used as a reference in an effort to prevent the spread of disease in fish culture. The sample of research consisted of tilapia fish, carp and catfish which were obtained from six sub districts in Banyuwangi, those were Kota, Kabat, Licin, Kalipuro, Giri, and Glagah. The ectoparasite examination method was performed naturally by scraping the surface of the body, fins and gills of the fish, then observed under a microscope with magnification ranging from 40 to 400x. The results of further observations were documented and identified by key identification. Ectoparasites which were found infesting freshwater fish in the city of Banyuwangi consisted of 4 genuses: namely Argulus, Lernaea, Chonopeltis and Trichodina. Further research is needed to determine the prevalence and intensity of ectoparasites in order to prevent the spread of ectoparasites in other regions. Keywords: Inventarisation, ectoparasites, freshwater fish, Banyuwangi

Abstract

Catfish (Clarias sp.) is one of Indonesia's leading fishery commodities whose production continues to be increased. Humic acid is known to help increase growth in several types of fish and is expected to be applied to catfish. This study aims to determine the effect of humic acid in commercial feed on the growth and total number of bacteria in the digestive tract of catfish (Clarias sp.). A total of 300 catfish with an average length of 5.76 ± 0.21 cm and an average weight of 27.92 ± 0.39 g were used in 5 treatments (4 replicates/treatments) of humic acid supplementation in feed with different doses, namely P1 (without humic acid/control), P2 (0.5 %), P3 (1.0%), P4 (1.5 %), and P5 (2.0 %). Maintenance was carried out for 40 days by feeding treatment 3 times a day as much as 5% of body weight. Parameters observed were absolute length growth (cm), absolute weight growth (g), specific growth rate (%), and total bacteria in the digestive tract (colonies/g). Based on the results of the study, it was found that the treatment had a significant effect on the growth and number of bacterial colonies with the optimal dose of humic acid of 0.5.Keyword : Behavior, Doses, Control, Colony

Abstract

Pacific white shrimp (Litopenaeus vannamei) is one of the leading fisheries commodities that have important economic value and are in great demand by consumers in the market. Pacific white shrimp has several advantages, namely rapid growth, able to adapt to a high range of salinity, and can be cultured with a super intensive system, but in recent years the total shrimp production in Indonesia has decreased. In 2012 the total shrimp production decreased from 1.900 tons to 1.025 tons, the virus is thought to be a pathogen that triggers disease in shrimp and causes high mortality. The type of virus that causes disease in pacific white shrimp cultivation is Taura Syndrome Virus (TSV), Infectious Myonecrosis Virus (IMNV), and White Spot Syndrome Virus (WSSV). The purpose of this study is to detect viruses that infected and determine the prevalence of viruses that attack pacific white shrimp. The research was conducted in December 2018 to January 2019 at Fish Quarantine Center, Quality Control and Security of Fishery Product Surabaya I. The material used in the study was 37 post larval samples. Samples extracted using Silica Extraction Kit, then detected molecularly using PCR (Polymerase Chain Reaction). This research was observational, then the data obtained were analyzed descriptively. The results showed that there were 3 positive samples of IMNV and 2 positive samples of WSSV with prevalence values of 8.10% and 5.40%. High and low prevalence values are influenced by the level of virus spread and inappropriate environmental conditions. Keywords : Pacific white shrimp, PCR (Polymerase Chain Reaction), prevalence, virus.

Abstract

The purpose of this study was to examine the effect of dietary supplementation with recombinant growth hormone (rGH) on the growth and dietary utility of juvenile giant gourami. The rGH was mixed with chicken egg yolk and sprayed on to artificial feed with different protein levels (34, 28, and 21%; isoenergy). Each treatment group of gourami was paired with a control group that received feed of the same protein level, but without rGH supplementation. Juvenile of giant gourami (weight 15.83 + 0.13 g) were fed diets containing rGH, to apparent satiation, 2 times a week. Fish were reared from less than 2 months old  for 42 days in 100 L glass aquaria at an initial density of 10 fish per aquarium. At the end of this period, the biomass and daily growth rate (SGR) of the fish were measured and the feed conversion ratio calculated and compared. Our data showed that fish fed rGH-supplemented diets experienced higher growth than fish in the control groups and showed that fish with higher protein diets experienced higher growth than the groups with less protein diets. The group with the highest biomass gain, SGR, and lowest feed conversion ratio (FCR) was the group fed a 34% protein diet supplemented with rGH. Furthermore, biomass gain, SGR, and FCR in the rGH treatment group with a 28% protein diet matched the measurements of the non-rGH control group receiving a 34% protein diet (P > 0.05). We conclude that giant juvenile gourami given feed supplemented with recombinant growth hormone will experience increased growth and dietary utility compared with gourami given the same feed without supplementation.

Abstract

Diseases caused by parasitic groups get less serious attention from the farmers because it is chronic morbidity and mortality rates and small. However, if observed further, parasitic diseases may trigger secondary infection by bacteria, viruses and fungi that can cause death and high losses. Thus this study aims to identify the types of ectoparasites that infected the seed goldfish in BBI Kabat, Banyuwangi which the results will be used as an early warning to prevent the death of fish in bulk. The research sample in the form of seeds 3-5 cm carp amounted 150 obtained from BBI Kabat, Banyuwangi. Ectoparasites inspection method performed by scraping the surface of the body, fins and gills of fish, and then observed under a microscope with a magnification ranging from 40-400x. The observation of ectoparasites are further identified accordance morphology based on the keys of identification. Identified ectoparasites infect seed goldfish in BBI Kabat, Banyuwangi consists of 8 genus is Zoothamnium sp., Trichodina sp., Oodinium sp., Vorticella sp., Argulus sp., Lernaea sp., Dactylogyrus sp., and Gyrodactylus sp. Further research is needed to determine the prevalence and intensity of parasites and appropriate measures to prevent the spread of parasites in healthy fish in BBI Kabat, Banyuwangi.
