Abstract

Graphical Abstract  Highlight Research Adjuvanted polyvalent FKC elicited the strongest and most sustained multi-arm immune response in Osphronemus goramy compared with monovalent and non-adjuvanted vaccines. The lead formulation combined high agglutinating antibody titres with enhanced NBT respiratory burst, indicating synergistic humoral–innate activation against Aeromonas hydrophila. Polyvalent vaccines did not dilute immunogenicity; instead, strain combination plus adjuvant broadened and amplified immune responsiveness. Longitudinal profiling of il-1β and ifn-γ revealed a stable pro-inflammatory/Th1-like cytokine signature uniquely associated with the adjuvanted polyvalent FKC. The integrated immunological “fingerprint” supports the adjuvanted polyvalent FKC as a rational lead candidate for motile Aeromonas septicaemia control in warm-water gourami aquaculture.   Abstract Motile Aeromonas septicaemia (MAS), predominantly associated with Aeromonas hydrophila, remains a major constraint in giant gourami (Osphronemus goramy) aquaculture. This study evaluated formalin-inactivated A. hydrophila vaccines prepared from MAS-associated field isolates, comparing a monovalent formulation (P2), a non-adjuvanted polyvalent formulation (P3), and an oil-adjuvanted polyvalent formulation (P4) against PBS controls (P1). A total of 240 fish were used (60 per treatment) and assigned to two parallel cohorts (immunology and survival/challenge). Immune endpoints (agglutinating titres, NBT activity, and splenic il-1β and ifn-γ transcription) were assessed on days 7, 14, 21, 35, and 42 post-vaccination. The survival cohort was challenged intraperitoneally at day 21 with a homologous A. hydrophila strain and monitored for 14 days post-challenge. Vaccination was clinically well tolerated and improved survival relative to controls, with P4 showing the highest protection (RPS 81.8%). Agglutinating titres differed by treatment and time; at the peak sampling point (day 35), mean titres in P4 were ~200-fold higher than in P1, and model contrasts indicated significant differences versus controls (p<0.001). Splenic il-1β and ifn-γ transcript levels were higher in vaccinated groups than in controls at later time points. These findings support further evaluation of an oil-adjuvanted polyvalent inactivated A. hydrophila vaccine for gourami, including dose optimisation, extended safety assessment, heterologous challenge, and field validation.

Abstract

Udang vaname (Litopenaeus vannamei) merupakan salah satu komoditas menjajikan yang bernilai tinggi. Budidaya udang vaname saat ini biasa menggunakan sistem intensif yang mana dapat mengakibatkan masalah lingkungan air budidaya kolam itu sendiri seperti limbah organik yang dihasilkan. Tujuan dari penelitian ini adalah untuk mengetahui aplikasi POC (Pupuk Organik Cair) pada persiapan kolam pembesaran budidaya udang vaname terhadap pertumbuhan, rasio konversi pakan, efisiensi pemanfaatan pakan, dan tingkat kelangsungan hidup udang vaname. Penelitian ini dilaksanakan di Instalasi Budidaya Air Payau Prigi, Trenggalek, Provinsi Jawa Timur pada Desember 2019 – Januari 2020. Metode kerja yang digunakan dalam penelitian ini adalah metode deskriptif dengan pengambilan data meliputi data primer dan data sekunder. Hasil yang didapat menunjukkan bahwa udang mengalami pertumbuhan sebesar 1,67-4,33 gram/hari dan selalu mengalami kenaikan. Nilai  FCR yaitu 1,6 dan EPP 62,5%. Tingkat kelulushidupan sebesar 51,3%. Rentang suhu selama penelitian berkisar 29°C-30,5°C sedangkan untuk pH berkisar antara 5,4-8, rata-rata nilai DO yaitu 4,86 mg/L, dan untuk salinitas berkisar antara 13-29 ppt. Keyword : pertumbuhan, kualitas air, tingkat kelangsungan hidup, pupuk organik cair.

Abstract

Moina macrocopa is natural feed that commonly found in tropical waters. Ephippia can be stored and hatched at any time. Embryo stability can be protect by controlling the water content through coating technology. Honey solution can be used as a coating that have a osmotic regulation for prevent embryo from drought while ephipia entering the dormant stage. This research aims to determine the effect of concentration on the hatchability of ephipia and the survival of M. macrocopa nauplii. The research method used in this study was experimental with a completely randomised design (CRD) using five treatments and four replications. The results showed that coating ephipia using honey had a significantly different effect on the hatchability of M. macrocopa ephipia (p<0,05). However, the concentration of honey was not significantly different on the survival of M. macrocopa nauplii. Keywords : Ephipia, Honey, Moina macrocopa, Coating
