Penelitian ini bertujuan untuk mengetahui pengaruh perendaman larutan daun kersen terhadap daya tetas dan kelangsungan hidup larva ikan mas. Penelitian ini dilaksanakan pada bulan Mei sampai Juni 2022. Metode yang digunakan adalah metode eksperimen dengan Rancangan Acak lengkap (RAL). Dengan konsentrasi larutan daun kersen 1,50 ml/L di rendam selama 5 menit, 10 menit, 15 menit dan tanpa perendaman (kontrol). Hasil uji ANOVA menunjukkan bahwa daya tetas telur ikan mas pada perendaman telur dengan larutan daun kersen berpengaruh sangat nyata (P>0,01), pada perlakuan D (81,67%), perlakuan C (66,67%), perlakuan B ( 63,00%) dan perlakuan A (61,67%). Sedangkan untuk hasil kelangsungan hidup berpengaruh sangat nyata (P>0,01) pada perlakuan D (58,06%), perlakuan C (44,02%), perlakuan B (41,23%) dan perlakuan A (30,06%). Kualitas air selama media pemeliharaan berada pada kisaran optimal untuk penetasan telur dan kelangsungan hidup ikan mas.

Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian serbuk daun Binahong terhadap total leukosit dan diferensisi leukosit Ikan Mas yang diinfeksi bakteri Aeromonas hydrophila. Penelitian menggunakan Rancangan Acak Lengkap yang terdiri atas 4 perlakuan dengan 3 kali ulangan. Perlakuan yang diuji yaitu perlakuan A (0 gram), B (30 gram), C (60 gram), dan D (90 gram). Pemberian pakan dilakukan 14 hari sebelum tantangan. Uji tantangan dilakukan dengan menyuntikkan 0,1 ml Aeromonas hydrophila dengan dosis 107 CFU. Penelitian ini menggunakan 120 ikan mas berukuran 12 cm selama 25 hari. Hasil penelitian menunjukkan perlakuan B memperoleh jumlah total leukosit tertinggi (246.050 sel/ml), disusul perlakuan D (207.917 sel/ml), perlakuan C (142.500 sel/ml) dan perlakuan A (111.733 sel/ml). Hasil uji diferensiasi leukosit perlakuan A (limfosit 49,00%, monosit 15.33%, neutrofil 15,33%,), B (neutrofil 6.6%, limfosit 72.3%, monosit 18.3%), C (neutrofil 7.9%, limfosit 66.1%, monosit 24.3%), D (neutrofil 11.2%, limfosit 57.6%, monosit 37.6%). Berdasarkan hasil penelitian dapat disimpulkan bahwa serbuk Daun Binahong dapat digunakan sebagai imunostimulan untuk meningkatkan kekebalan tubuh Ikan Mas.

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.

Comet fish (Carassius auratus auratus) is one type of freshwater ornamental fish that is highly demanded by the ornamental fish hobbyist community because it has a variety of colors and attractive physical forms. However, comet fish cultivation has decreased due to disease attacks that lead to death caused by Aeromonas hydrophila bacteria. Therefore, farmers generally use chemical drugs such as antibiotics to treat diseases in comet fish, yet for antibiotics, and it is necessary to research herbal medicines that contain antibacterial content, such as turmeric (Curcuma domestica). This research aims to determine the effect of immersion time using turmeric extract solution for treatment and survival rate of comet fish seeds infected with A.hydrophila bacteria. This is experimental research with a Completely Randomized Design (CRD) consisting of four treatments and three replicates, namely treatment A (control), B (50 minutes immersion), C (60 minutes immersion), and D (70 minutes immersion). The results showed that using turmeric extract affected treating comet fish seeds infected with A.hydrophila bacteria. As for the survival rate, the results of analysis of variance (ANOVA) showed that the use of turmeric extract had no significant effect, with the percentage value of the survival rate of comet fish seeds of treatment A (63.30%), B (90.00%), C (80.00%), and D (86.60%).

The present study aimed to identify the Octolasmis spp. ectoparasite's intensity and prevalence in mud crab in Pohuwato Regency. It employed survey and site observation methods with sampling technique of mud crabs in Pohuwato Regency. The research was carried out in three different sites: site 1 (Pohuwato Timur Village), site II (Bulili Village), and site III (Mootilango Village). The results showed that the parasites infesting mud crab in the three separate locations are Octolasmis angulata and Octolasmis cor. The highest intensity rate was at site III, which was dominated by Octolasmis cor. The prevalence of the parasite in sites I, II, and III was 60%, 40%, and 60% in consecutive order. Moreover, the parasite has a 100% and 46% prevalence in female and male crabs, respectively. The water quality indicator (involving temperature, pH level, and soluble oxygen) was at the appropriate rate for mud crab farming.

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.
