Abstract

Captive breeding of seahorses (Hippocampus barbouri) which is a follow-up of their activities in the exploitation of natural large - scale does not escape from the problems of the disease. Gills and kidneys are the main target of the inspection. Wet mount is one way of checking the disease. This study aims to look at other forms of bacteria isolated from the gills and kidney seahorse (H. barbouri) morphologically. Media used are media Zobell Marine Agar (ZMA) and Thiosulphate Citrate Bile Salts Sucrose Agar (TCBSA) then be isolated bacteria with a pillowcase technique spread to see koloi dominant bacteria. more dominant bacteria grow dimurinikan back with scratch method (streak). The result of five isolates (isolates A, B, C, D and E) were predominantly found growing on media ZMA, two isolates (isolates B and C) not found growing on media TCBSA. Overall bacteria in media and TCBSA ZMA has the form round colonies and smooth-edged. TCBSA media can not be found on the bacterial colonies that fluoresce.

Abstract

Kerupuk merupakan salah satu olahan tradisional yang digemari masyarakat Indonesia. Selama ini kerupuk diolah dengan menggunakan bahan baku seperti udang dan ikan utuh. Oleh karena itu, fortifikasi kerupuk dengan tepung tulang ikan memiliki beberapa keunggulan antara lain kandungan nutrisi protein dan mineral kerupuk lebih baik, dapat menekan biaya produksi jika dibandingkan dengan menggunakan bahan baku ikan utuh atau udang dan limbah tulang tuna dari industri pembekuan ikan dapat dimanfaatkan. mengurangi jumlah sampah yang dibuang ke lingkungan

Abstract

Artifficial fee nutrition can be enhanched by adding vitamin C, aiming to suport the growth and survival of female Nile tilapia (Oreochromos niloticus). The addition of vitamin C to feed for the growht an d survival of fish has been extensively studied. However, there is still limited research specifically focusing on female Nile tilapia. The study aims to investigate the effect of vitamin C supplementation in feedd and to determine the optimal dosage for the growth and survival of fimale Nile tilapia juveniles. The research adopts an experimental approach using a Completely Randomized Design (CRD), consisting of 4 treatments and 3 replications. The treatments include A (Vitamin C 200 mg/kg feed), B (Vitamin C 300 mg/kg feed), C (Vitamin C 400 mg/kg feed) and D (Without vitamin C supplementation). Based on the results, the treatment with 300 mg/kg feed provide the best outcome, followed by treatment A and treatment C. The ANOVA analysis results indicate that there is no significant effect on growth (Fcount < Ftable) with a significance value >0.05, while there is a significant effect on survival (Fcount > Ftable) with a significance value < 0.05. Therefore, it is concluded that adding vitamin C to feed does not significantly affect the growth of female Nile tilapia juveniles but results in better growth compared to not providing vitamin C. In addition, of vitamin C significantly affects survival. Keywords: Female Nile Tilapia, Growth and Survival, Vitamin C

Abstract

The freshwater lobster (Cherax quadricarinatus) is a precious commodity within the freshwater aquaculture sector. It is essential to investigate the effects of different natural feeds on lobster growth to enhance aquaculture practices. This study aimed to identify the types of natural feed that influence and improve freshwater lobster juveniles' growth and survival rate. This study was conducted from January to February 2024 at the Kasih Karunia Suwawa Aquaculture Hatchery. A Completely Randomized Design (CRD) was applied, with four treatment groups: Treatment A (bean sprouts), Treatment B (Tubifex sp.), Treatment C (tofu residue), and Treatment D (a combination of bean sprouts, Tubifex sp., and tofu residue). The feed was administered daily at 7% of the total biomass, with a feeding frequency of twice per day. Data were analyzed using ANOVA with SPSS software. The observed parameters included length growth, weight growth, survival rate, and moulting frequency. The results showed that Treatment B (Tubifex sp.) yielded the best growth and moulting frequency, with length growth at 0.76 cm, weight growth at 0.70 g, and moulting frequency at 0.67. The highest survival rate, at 96.67%, was observed in Treatment D (bean sprouts + Tubifex sp. + tofu residue). ANOVA results indicated that different types of natural feeds did not significantly impact the growth and survival of freshwater lobsters.

Abstract

This research aims to determine the use of rice straw as a packaging medium for the survival, growth, induction, and sedation of lobster seeds transported for 6, 9, and 12 hours using the Completely Randomized Design (CRD) method. The research preparation includes preparing the maintenance medium, filling medium, and test animals (adaptation for 7 days after arrival and fasting for 24 hours). The main research involves acclimating lobster seeds using temperature manipulation for approximately 5 minutes, with transport media temperatures ranging from 10º to 12º, and then maintaining them for 28 days. The research results indicate survival, growth, induction, and sedation time differences. The fastest induction time occurred in the treatment with a 9-hour transport duration, lasting 4.14 minutes. The fastest sedation time occurred in the 6-hour transport duration, lasting 1.56 minutes. Post-transport survival is highest after 6 hours and 9 hours of treatment, which is 95%. The best post-maintenance survival is found after 6 hours of transportation, at 91%, while the treatments at 9 and 12 hours yield 86% and 76% results, respectively. This research indicates that straw can be utilized as a filling medium for up to 12 hours.

Abstract

Majalaya carp (Cyprinus carpio) is one of the essential commodities used to increase fisheries production in Indonesia. However, this cultivation activity is often hampered by disease problems caused by parasites. Therefore, it is necessary to research the inventory of ectoparasites in Majalaya carp with different sizes. This study aims to determine the type, intensity, and prevalence of ectoparasites in Majalaya carp of different sizes. Samples were taken by random sampling from cultivation ponds in the North Minahasa Regency, North Sulawesi Province. The research method used a descriptive method, and for ectoparasite examination, a native method was used by examining the surface of the fish's body, mucus, fins, gills, and eyes. The study results found six types of ectoparasites: Dactylogyrus sp, Argulus sp, Ichthyophthirius multifiliis, Trichodina sp, Vorticella sp, and Gyrodactylus sp. At a size of 4-7 cm, more Dactylogyrus sp were found. On the gills, size 8-14 cm I. multifiliis on mucus and size 23-30 cm Argulus sp on the surface of the fish body. The intensity level of ectoparasites produced on Dactylogyrus sp reached a value of 5.14 Ind/fish (low infection), I.multifiliis 4.27 Ind/fish (low infection), and Argulus sp of 3.80 Ind/fish (low infection). Then, the prevalence level of ectoparasites produced on Dactylogyrus sp reached a value of 70% (moderate infection), Ichthyophthirius multifiliis 50% (persistent infection), and Argulus sp 67% (persistent infection). This study emphasizes the importance of water quality management and fish density regulation.
