Abstract

This study aimed to determine chloramphenicol residues and bacterial contamination (Aerobic Plate Count-APC, Escherichia coli count, Salmonella sp., and Vibrio cholerae) in farmed African catfish (Clarias gariepinus) that are marketed in Banyuwangi, Indonesia. A total of ninety samples of C. gariepinus were collected from several markets in Banyuwangi, namely, Kertosari, Blambangan, and Banyuwangi Kota. Using standard procedures, APC, E. coli count, Salmonella sp., V. cholerae, and chloramphenicol residues were determined. 36.37% of samples from Kertosari markets; 23.33% of samples from Banyuwangi Kota markets; and 16.67% of samples from Blambangan markets contained chloramphenicol residues, but less than 0.3 ppb. Only 40% of samples from Kertosari markets, 36.67% of samples from Banyuwangi Kota markets, and 26.67% of samples from Blambangan markets were contaminated by E. coli, but were less than 3 MPNg-1. The highest APC was from Banyuwangi Kota, followed by Kertosari and Blambangan. No samples were contaminated by Salmonella sp. and V. cholerae from any of the markets, and there was no significant difference between all markets in APC, E. coli count, or chloramphenicol residues. All farmed catfish marketed in Banyuwangi were safe to eat because no samples exceeded the maximum chloramphenicol residue and bacterial contaminant standards. Further studies are needed to detect other antibiotic residues used in aquaculture, including tetracycline, sulphonamide, enrofloxacin, and nitrofuran. [ABSTRACT FROM AUTHOR]

Abstract

Olive ridley (Lepidochelys olivacea) is one of the endangered sea turtle species that live in Indonesian waters. The current population of olive ridley sea turtle continues to decline caused by number of factors. One of the contributing factors is the presence of contaminant microbes in turtle eggs which have important role in declining the percentage of eggs hatching success. The aim of this study was to investigate the role of microorganism infection as major factor which decreasing the egg hatching success at the olive ridley turtle conservation area in Banyuwangi coastal area, Indonesia. The microbial contaminants detection was carried out on the eggs which fail to hatch and sand at the semi-natural hatching nest. A total of 255 eggs were divided equally and incubated in three different nest area with 40, 60, and 80 cm depths respectively. The results showed that the Gram-negative microorganisms were from the coliform bacteria such as Escherichia coli, Enterobacter cloacae, Proteus spp., and Salmonella spp. Meanwhile, the Gram-positive microorganisms were dominated by Bacillus spp. and Staphylococcus aureus. The hatching success rate was 89.4% in 80 cm depth, 62.3% in 60 cm depth and 25.8% in 40 cm depth respectively. The contaminant microorganism might reduce the hatching success, and moreover, the semi-natural hatching nest needs regular sand removals and replacement with new sand to sterilize the contaminant of microorganism. Present suggestion in this study also aimed to increase the hatchery success and generally support the conservation program in sea turtle as endangered species. [ABSTRACT FROM AUTHOR]

Abstract

Eel (Anguilla bicolor) is an important commodity and has a high economic value. This fish is rarely cultivated because, apart from the limited availability of seeds, the growth rate is relatively slow. This study aims to determine the value of growth rate, feed efficiency and fcr of Anguilla bicolor which is fed with bromelain enzyme supplementation. The method used was a completely randomized design (CRD) with four treatments and five replications. Data analysis used the ANOVA test with a confidence level of 95% and Duncan's advanced test (DMRT). Bromelain enzymes have a significant effect on FCR and feed efficiency. However, there was no significant effect on growth parameters in Anguila bicolor. However, the best treatment in this study was P4 with GR 0.38 ± 0.03 g/day, SGR 0.95 ± 0.03 %/day, FCR 1.97 ± 0.15 and feed efficiency of 50.9 ± 4.17%. [ABSTRACT FROM AUTHOR]

Abstract

Disease is one of the main problems that have a major impact on aquaculture activities. Diseases in fish generally occur due to an imbalance of interactions between fish, pathogens, and the culture environment. Poor environmental quality can increase stress on fish and increase the pathogenicity of pathogens. In aquaculture activities, it is important to prevent disease in fish to avoid large economic losses. Based on the result of the initial survey, it was found that the problems faced by fish farmers in the Genteng area were the lack of knowledge in identifying the early syndrome of fish disease and the weakness in monitoring the quality of water for cultivation. This program aimed to provide the fish farmer with an introduction to disease kinds, training in environmental health management, and mentoring activities for aquaculture activities so that fish diseases can be prevented as early as possible. This programs were carried out on August 18, 2022, which was attended by 20 fish farmers in the Genteng area and continued with regular assistance for one month. Based on the result, there was an increase in understanding of the identification of parasites in fish, microscope utilization, and water quality test. In general, this programs received a positive response and enthusiasm from training participant, which was accompanied by an increase in participants' knowledge about how to identify fish disease and water quality test.

Abstract

Indonesia offers a large variety of marine ornamental fish. The growth and prospects of ornamental fish commodities in Indonesia have accelerated, particularly during the COVID-19 pandemic. However, it is not uncommon for growers to face yield failure owing to pests and diseases during the process. This is a barrier to serving the needs of both domestic and international clients. As a result, fish quarantine procedures are required to avoid the spread of parasite illnesses. The goal of this study was to look for and identify parasites in marine ornamental fish before they were delivered to Denpasar, Bali's Fish Quarantine Center, Quality Control and Safety of Fishery Products. Traditional parasite examination methods were used, such as scraping the body surface, gills, fins, and operculum of fish for ectoparasites and fish intestines for endoparasites. In addition, parasites were studied morphologically. The inspection revealed Dactlogyrus and Balantidium parasites on the gills, Benedenia on the caudal fin, and Archigetes, Spirocamallanus, and Hexangium in the gut. [ABSTRACT FROM AUTHOR]

Abstract

Humpback grouper (Cromileptes altivelis) or also known as polkadot grouper is one of the excellent fish commodities in Indonesia which has trading value reached $ 90-150/kg. As a consumed fish, humpback grouper are needed for beverage at luxuries restaurant and hotel in the world. As major export commodities in Indonesia, since the 1990's the techniques of grouper cultivation in float net rats are enhanced to fulfill international market demand. Humpback grouper fish cultivation techniques in float net cages cannot be separated from the problems in any cultivate activities, one of the causes is a disease and one of the diseases that rushed humpback grouper is parasite. The disadvantages that caused by the parasite is fish’ weight loss. The purpose of this study is to determine the types of endoparasites that attacked the digestive system of humpback grouper (Cromileptes altivelis) in float net cages and also to discuss the prevalences of endoparasites that attack the digestive of humpback grouper (Cromileptes altivelis) in float net cages. The method of this research is descriptive. The sampling was done in once for 60 fishes with the length range of fish is around 15-20 cm and 4 months old from the float net. The number of each fishes samples that were taken 5-10% from the total of population, where the number of humpback grouper populations in each raft float net are 200 fishes. The main parameters that observed in this study were endoparasites identification species that attack the digestive system of humpback grouper (Cromileptes altivelis) in float net cages and the prevalence rates for each endoparasites. The supporting parameters in this study were the water quality in float net cages which includes temperature, pH and salinity are measured during the sample taken. The results showed that 60 samples taken from four float nets 6 fishes were positive infected endoparasitic of trematodes and nematodes, besides 4 fishes are positive infected worms Echinostoma which belong to the class of Trematodes and 2 fishes infected worms Camallanus carangis that belongs to the class Nematoda. The prevalence values for each of the worm are 6.67% for Echinostoma and 3.33% for Camallanus carangis. The research concern the identification and prevalence of endoparasites in Humpback grouper at hatchery is needed to early finding out the attack of endoparasites and to break the flow of endoparasitic spreading.
