Farming of red tilapia is one promising direction in aquaculture. The objective of this study was to investigate the impact of long-day photoperiod on the growth performance, reproductive parameters, maturity, sex ratio, β-carotene content, and skin coloration of red tilapia. Early life larvae were allocated into three treatment groups in triplicates: T1 = control group (12L:12D), T2 = long-day group (18L:6D), and T3 = continu...

This study provides comprehensive results on the growth, thyroid, liver, and gonadal condition, maturity, and sex ratio in red tilapia exposed to exogenous thyroxine and goitrogen. One-gram red tilapia fingerlings were reared in three groups: control, thyroxine (T4) (10 nM), and goitrogen (sodium perchlorate, 30 mg/L) for 30 days, followed by 30 days without treatment. After the first 30 days of treatment, liver enzymes and wh...

Summary In livestock production, antibiotics are used to promote animal growth, control infections and thereby increase profitability. This practice has led to the emergence of multiresistant bacteria such as Salmonella , of which some serovars are disseminated in the environment. The objective of this study is to evaluate microcin J25 as an inhibitor of Salmonella enterica serovars of various origins including human, livestoc...
