Abstract

The research with the aim to know the effectivity (yield gap) of the application of Streptococcus agalactiae vaccine (pure whole cell) in prevention of streptococcosis on tilapia (Oreochromis niloticus) culture has been carried out. The isolate of S.agalactiae – N14G was used as a master seed on vaccine production. Priming vaccination was administered by immersion method, and booster vaccination was taken th place two months latter by oral method. Challenge test at the lethal dose (LD50) against active bacteria was done at 14 days post booster vaccination, and observation was taken place for 14 days post artificial infection. The results of the research showed that the highest survival rate and relative percent survival (RPS) was found in group treated with Streptovac vaccine (S. agalactiae and A. hydrophila combination) (65.58% and 35.36%) followed by S. agalactiae vaccine (52.08% and 10.01%). The lowest survival rate was found in control group (46.75%). The result of confirmation effectivity of the vaccines by challenge test in the laboratory showed that the highest survival rate and relative percent survival (RPS) was found in S. agalactiae vaccine (50.00% dan 37.50%) followed by Streptovac vaccine (40.00% and 25.00%), and the lowest survival rate was found in control group (20.00%). Vaccination is better than the non vaccinated.

Abstract

The research with objective to understand optimization frequency of supplemented ascorbic acid (microencapsulated vitamin C CFC-90) feeding to control the Koi Herpes Virus (KHV) disease infecting common carp has been done in Fish Disease Laboratory Fishes were reared in plastic container (80 litres), with density of 20 fish sized 10 gram in average. The treatments were: (A) daily application, (B) three daily application, (C) five daily application, and (D) without vitamin C as a control. Examined fishes were challenged to KHV infection after the 21 days rearing period by cohabitation method for 2 weeks. Observations been done on behaviour, clinical signs and mortality of fishes. The results showed that the highest survival rate was found on the application o vitamin C given every 3 days (50.0%); followed by every day (12.5%), every 5 days (7.5%), and the lowest was found on contro group (1.3%). Control techniques in the case of KHV carp populations through the provision of vitamin C immunostimulatory conducted regularly since well before the existence of KHV infection provides the best protective level.

Abstract

This review aimed to provide the current status of streptococcosis in freshwater aquaculture in Indonesia. So far, this disease has been mostly reported in tilapia aquaculture, and there have been no serious reports of this disease in other species of freshwater aquaculture. The disease is mostly encountered during the dry season or the transition period from the dry season to the rainy season or vice versa. Initially, the disease was mostly reported in tilapia larger than 250 grams, but in its development, it was also reported in smaller fish. The Ministry of Marine Affairs and Fisheries (MMAF) has classified this disease as a major disease in tilapia in Indonesia since 2014. Based on the characteristics of Streptococcus agalactiae isolates collected from diseased tilapia from various regions in Indonesia, two biotypes were found consisting of ?-hemolytic S. agalactiae (biotype I) and non-hemolytic S. agalactiae (biotype II). Biotype I cause disease with acute mortality patterns, while biotype II causes disease with chronic and persistent mortality patterns. Based on susceptibility to S. agalactiae during artificial infection testing, it is known that all tilapia strains that have been released to the public for aquaculture purposes are susceptible to infection with the bacteria; although each strain has a different level of susceptibility. Fish health management strategies that are based on preventive measures and relevant to sustainable aquaculture programs should be based on ecological-biological approaches such as the implementation of biosecurity systems, the use of vaccines for endemic diseases, probiotics, essential herbs, and the development of more disease-resistant populations.Keywords: health management, streptococcosis, Streptococcus agalactiae, tilapia

Abstract

Abstract Mahseer "dewa" (Tor soro), snakehead "gabus" (Channa striata), and bagrid catfish "baung" (Hemibagrus nemurus) are local specific fish species that are promising to be developed as freshwater aquaculture commodities in Indonesia. Disease cases/outbreaks in those fish farming have often been reported, however, there is not much information on the epizootiology and disease status of those fish species. The susceptibility of those fish to parasitic infection was evaluated by natural and artificial infection. Natural infection was conducted by randomly sampling 20 fish at 5-day intervals and lasting for 30 days. In artificial infection, 150 tested fish cohabited with 40 parasite-carrying fish that were known to be definitely infected by the parasite. The observation was carried out by sampling 20 fish at 5-day intervals and lasting for 30 days. The results showed that the three fish species were susceptible to infection with Trichodina spp, Epistylis spp, Tetrahymena spp, Ichtyophthirius multifiliis, Dactylogyrus spp, and Gyrodactylus spp, while the helminth parasite Pallisentis nagpurensis (Acanthocephala) was only identified in snakehead. A number of parasites such as I. multifiliis, Dactylogyrus spp., and Gyrodactylus spp. are likely to be potential obstacles in the cultivation of those fish species, especially in hatcheries and nurseries. Keywords: mahseer, snakehead, bagrid catfish, parasites

Abstract

The purpose of this research is to develop Canva-based learning media using the Project-Based Learning model in Pancasila Education at STIKES Hang Tuah Surabaya that is valid and practical. The method used in this research and development is the ADDIE model. Data were obtained from validation questionnaires and practicality question-naires. The research subjects consisted of 3 expert validators covering media, language, and content, while peer testing involved 1 person, and 23 nursing students from STIKES Hang Tuah Surabaya. The results of the media development research showed that the content validity level was 90 percent categorized as very valid, language validity was 95 per-cent categorized as very valid, and media validity was 98 percent cate-gorized as very valid. Furthermore, the practicality response from stu-dents was 89.31 percent categorized as very practical, while the feed-back from educators showed 91.66 percent categorized as very practi-cal. The results of the study found that the Canva-based learning media using the Problem-Based Learning model is very valid and practical for use in Pancasila education for nursing students at STIKES Hang Tuah Surabaya.
