“…From this, 73,181 tons came from the north of the country (IBGE, 2021). On the other hand, with this intensification in tambaqui production, important bacterial pathogens have been identified in these fish, with potential to cause significant economic losses in production, especially due to disease outbreaks caused by Aeromonas (VALLADÃO et al, 2018;HILSDORF et al, 2022).…”

The aim of this study was to molecularly identify different species of Aeromonas isolated from farmed tambaqui (Colossoma macropomum) from North Brazil, and evaluate their pathogenic potential by the presence of virulence genes. From the extraction of bacterial DNA, PCR (polymerase chain reaction) of the primers 16S rDNA, aerA (cytolytic enterotoxin), ast (cytotoxic enterotoxin) and act (cytotoxic enterotoxin) were performed. Of 24 isolates evaluated, eight amplified the ast gene, one amplified the act gene, but the areA gene was not amplified in any isolate. Sequencing of the 16S rRNA primer revealed a predominance of Aeromonas jandaei specie (92%). Aeromonas taiwanensis (4%), for the first time isolated from fish in Brazil, and Aeromonas hydrophila (4%) each appeared as just one isolate. Results showed that 32% of Aeromonas isolated from farmed tambaqui have considerable pathogenic potential for systemic damage, since the selected PCR primers are encoding the most common virulence genes in Aeromonas with high pathogenic intensity.

“…Perbandingan induk ikan jantan dan induk betina adalah 3:1 Pemijahan adalah proses pembuahan telur oleh sperma. Pemijahan umumnya diinduksi dengan cara menyuntikkan hormon reproduksi ke tubuh induk, yang disebut juga dengan induced spawning (Hilsdorf et al, 2021). Pemijahan jenis ini merupakan pemijahan ikan yang dilakukan secara alami namun dengan bantuan induksi hormon sebelumnya (Woynárovich & Van, 2019).…”

Desa Purwasari memiliki potensi sumber daya di bidang akuakultur yang belum dimanfaatkan secara maksimal, seperti kolam ikan, sumber daya air dari sistem irigasi pertanian, dan sumberdaya manusia melalui kelompok petani ikan. Masyarakat memiliki minat yang tinggi terhadap kegiatan akuakultur, akan tetapi minimnya pengetahuan terkait aspek-aspek budidaya masih menjadi hambatan. Selain itu, biaya pakan komersial yang tinggi juga menjadi salah satu faktor pembatas utama kegiatan budidaya ikan. Tujuan kegiatan pengabdian kepada masyarakat ini adalah meningkatkan pemberdayaan masyarakat Desa Purwasari melalui kegiatan budidaya ikan bawal dan maggot dalam meningkatkan profitabilitas serta ketahanan pangan desa selama masa pandemi Covid-19. Metode kegiatan ini dilakukan secara hybrid, yaitu kegiatan offline yang dilakukan untuk survei lapang dan controlling; serta kegiatan online yang dilakukan untuk menyebarkan kuisioner setiap bulan, mengadakan pertemuan antara dosen, pemateri dan masyarakat desa. Kegiatan ini menghasilkan adanya transfer ilmu pengetahuan dari pendidikan tinggi (Institut pertanian Bogor) ke masyarakat. Berdasarkan hasil kuisioner, kegiatan ini dipandang meningkatkan pengetahuan, keterampilan, jumlah anggota, dan tanggung jawab setiap individu dalam kelompok petani. Indikator perubahan fisik dapat dilihat dengan adanya revitalisasi kolam dan pengadaan infrastruktur budidaya ikan bawal serta maggot. Selain itu, kegiatan ini membentuk kelompok tani milenial yang beranggotakan calon pembudidaya ikan bawal dan maggot. Kegiatan pengabdian kepada masyarakat ini bersifat aplikatif di Desa Purwasari, dan berpotensi meningkatkan profit serta ketahanan pangan masyarakat Desa Purwasari selama masa krisis akibat pandemi Covid-19.

“…However, with the intensi cation of sh farming, there is an increase in stressful conditions, which may be linked to the remarkable drop in productivity of the species. This went from 29.43% of Brazilian sh production in 2014, to 19.09% of production in 2019 (Hilsdorf et al 2022). As such, it is important to research products that are capable of favoring the development of the animal and, in turn, boost the production chain of tambaqui.…”

The present study evaluated the effects of commercial guarana (Paullinia cupana) powder as a growth-promoter and natural antioxidant supplement in aquafeeds. In Experiment 1, fish were fed with graded levels of guarana powder (0, 1.25, 2.5, 5 and 10 g/kg) during 60 days. Growth, hemato-immunological and biochemical performance were evaluated in healthy fish and in fish after infection by Aeromonas jandaei. In Experiment 2, the supplemented feed was stored for 90 days, in which tests were carried out regarding the quantity of phenolic compounds and the inhibition of lipid peroxidation. As a result of Experiment 1, fish fed guarana-supplemented diets and infected by A. jandaei presented better parameters of leukocyte respiratory activity, total proteins, globulin, albumin, alanine aminotransferase (ALT), leukocytes, lymphocytes, neutrophils, monocytes and thrombocytes. As a result of Experiment 2, levels of phenolic compounds were not altered (p > 0.05) by the guarana-supplemented diets. An increase in the concentration of malondialdehyde (MDA) and a lower oxygen radical absorbance capacity (ORAC) was observed in the fish fed diets with the highest level of guarana supplementation. As conclusion, guarana did not impair productivity and revealed a possible cytoprotective and hepatoprotective effect in fish infected by A. jandaei. Therefore, guarana seems to be an interesting additive to be included at levels of up to 1% in special feeds to be used prior to stressful situations in aquaculture. Additionally, guarana had no protective effect against lipid peroxidation and showed a pro-oxidant effect in diets with higher supplementation levels.
