ABSTRACT Outbreaks of infectious diseases due to Aeromonas hydrophila in catfish can cause high death rates (80–100%). Fish disease control can be done using phytopharmaceutical to prevent or treat diseases of fish. One of the phytopharmaceutical that known to prevent the fish diseases is ambon banana stem Musa cavendishii var. dwarf Paxton. This study was conducted to test the effectiveness of catfish immersion using banana stem juice as an immunostimulant against bacterial infections A. hydrophila. The observed parameters were a total performance of production, hematological test, and water quality. Immersion of catfish seeds with stem juice was performed at a concentration of 5 mL/L, 13 mL/L, and 21 mL/L for 30 minutes. Each treatment consisted of three replications. A total of 15 fishes were immersed in 1.5 L water. At day-9 after immersion, fish was infected by A. hydrophila bacteria at a dose of 104 cfu/mL. The results showed that fish treated with banana stem juice at a concentration of 13 mL/L had the survival rate of 53.33±6.67% which is higher than positive control (33.33±6.67%). Based on hematology observations on the 3rd day post-challenge test (H12) with A. hydrophila, total erythrocytes, hemoglobin, total leukocytes, phagocytic activity, differential leukocyte, and lysozyme activity was highest in treatment13 mL/L. Lower feed conversion ratio (1.08±0.04) were also obtained in treatment 13 mL/L. Thus Immersion of seeds in stem juice can boost the immune system against infections A. hydrophila.

Suhu dan salinitas merupakan parameter kualitas air yang berperan penting terhadap proses fisiologis siput mata bulan (T. chrysostomus) sehingga berdampak terhadap perkembangan, pertumbuhan dan kelangsungan hidup larva. Tujuan dari penelitian ini yaitu untuk mengevaluasi pengaruh suhu dan salinitas terhadap perkembangan, pertumbuhan dan kelangsungan hidup larva siput mata bulan (T. chrysostomus). Stadia pre-torsion veliger dicapai sekitar 11 jam 36 menit setelah fertilisasi atau sekitar 3 jam setelah trocophor. Stadia post-torsion veliger awal ditandai dengan cangkang yang telah terbentuk sempurna dan pada post-torsion veliger akhir, larva sudah mengembangkan operkulum, kaki, dan propodium. Hasil pengamatan menunjukan bahwa perlakuan A1B3 memberikan waktu pencapaian stadia post-torsion veliger awal dan post-torsion veliger akhir tercepat yaitu masing-masing 19 jam 36 menit dan 22 jam 36 menit setelah pembuahan. Sedangkan perlakuan A1B1 memberikan waktu pencapaian stadia post-torsion veliger awal dan post-torsion veliger akhir terlama yaitu masing-masing 20 jam 30 menit dan 23 jam 25 menit setelah pembuahan. Suhu tidak berpengaruh nyata sedangkan salinitas berpengaruh nyata terhadap laju pertumbuhan harian larva siput mata bulan. Laju pertumbuhan harian tertinggi pada suhu 27±0.5oC (A1) tercatat pada perlakuan B3 dan menunjukan nilai yang tidak berbeda nyata dengan perlakuan B2. Suhu dan salinitas memberikan pengaruh yang signifikan namun interaksi keduanya tidak menunjukan pengaruh yang signifikan terhadap tingkat kelangsungan hidup larva siput mata bulan. Perlakuan A1B3 memberikan persentase tingkat kelangsungan hidup tertinggi dan tidak menunjukan nilai yang berbeda nyata dengan perlakuan A1B2. Parameter kualitas air yang diperoleh masih mendukung performa larva siput mata bulan hingga mencapai stadia juvenil.

The increasing use of mercury in the industrial sector poses significant risks to freshwater ecosystems and aquatic organisms. Milkfish (Chanos chanos), a widely consumed species, is now being reared in freshwater environments, raising concerns about mercury bioaccumulation and food safety. This study aimed to determine the median lethal mercury concentration for milkfish at 96 hours (LC50) in freshwater using an experimental approach and probit analysis. Five mercury concentrations were tested: 0 (control), 0 .110 mg Hg/L, 0.195 mg Hg/L, 0.347 mg Hg/L, and 0.618 mg Hg/L. The results indicated that mercury is highly toxic to milkfish, with a 96-hour LC50 of 0.147 mg Hg/L. Clinical symptoms observed included loss of reflex movements, irregular swimming, frequent surfacing with widened mouth and operculum openings, convulsions, and ventilation of the ram before mortality.
