Male tilapia fish grow faster than female tilapia, so administering synthetic steroids orally or by soaking has proven to be the simplest, easiest, most effective and reliable technology for sex reversal of tilapia larvae to become males. This research was conducted to analyze the administration of 17α- methyltestosterone on the growth rate and feed conversion of tilapia (O.niloticus). This study used a completely randomized design (CRD) consisting of 3 treatments and 4 replications. The optimum dose used is (60) mg/kg feed, and 0.5 ml/l. The results of this study showed that body weight gain with oral treatment had the best average, namely 226.83c ± 11.88; average length 12.79b ± 0.99, specific growth rate (SGR) 5.46c ± 0.06 and FCR namely 1.05a ± 0.06. Research on the effect of using 17α-methyltestosterone on the growth of oral male tilapia fish obtained the best results by not exceeding the residue limit (5 µg/L or 5 µg/kg) of synthetic steroids in the body of tilapia fish.

Proses pembenihan udang vannamei melibatkan pengelolaan kondisi lingkungan dan kualitas air yang optimal untuk mendukung perkembangan larva. Kualitas air yang buruk dapat mendukung bakteri Vibrio sp. menyebar secara cepat. Parameter kualitas air seperti Total Organic Matter dan alkalinitas berpengaruh terhadap kelimpahan Vibrio sp. Penelitian ini dilakukan untuk mengetahui pengaruh TOM dan alkalinitas serta interaksinya terhadap pertumbuhan dan kelimpahan Vibrio sp. Pengujian ini dilakukan pada 3 kolam yaitu kolam A22, A23, dan A27. Parameter kualitas air yang diuji adalah Total Organic Matter (TOM), Alkalinitas, dan Total Vibrio Count (TVC). Pengujian tambahan juga dilakukan untuk parameter pH, Nitrit (NO2), dan Total Ammonium Nitrogen (TAN). Berdasarkan hasil pengujian menunjukkan bahwa kelimpahan bakteri Vibrio sp. di pembenihan udang vannamei tidak dipengaruhi secara signifikan oleh bahan organik dan alkalinitas. Hal ini tidak bisa terlepas dari faktor parameter kualitas air lainnya.

Jaundice remains a recurrent problem in small-scale catfish aquaculture and contributes to reduced market value and economic losses for farmers. This community service program aimed to enhance the capacity of catfish farmers in Gelang Village, Tulangan District, Sidoarjo Regency, in producing and utilizing herbal immunostimulants as a preventive strategy. The program involved 10 farmers and was implemented through technical training consisting of theoretical sessions, hands-on practice, and mentoring. The immunostimulant introduced was prepared using a simple decoction method from locally available ingredients including Terminalia catappa, ginger, galangal, turmeric, and Curcuma xanthorrhiza. Quantitative evaluation showed an average knowledge increase of 147 percent from pre-test to post-test, with all participants exceeding the minimum improvement target. Practical skill assessment indicated an average mastery score of 94 percent, and 100 percent of participants were able to independently produce the extract. The readiness to adopt the technology reached an average score of 93 percent. Field observations indicated perceived effectiveness in supporting preventive health management practices. However, no laboratory analysis or biological measurements were conducted. This program primarily strengthened farmers’ knowledge, technical skills, and adoption readiness toward locally based preventive approaches that may support sustainable small-scale catfish farming.
