Rainbow Trout Oncorhynchus Mykiss

Insects are emerging as a sustainable alternative to fishmeal and fish oil in aquafeeds. This study assessed the effect of graded incorporation levels of defatted yellow mealworm (Tenebrio molitor) protein meal on juvenile rainbow trout (Oncorhynchus mykiss) growth performance, body composition, and apparent nutrient digestibility. The trial comprised five dietary treatments: control diet with 25% fishmeal, and four experimental diets with yellow mealworm protein meal at 5%, 7.5%, 15%, or 25%, which corresponded to a fishmeal replacement of 20%, 30%, 60%, or 100%, respectively. After 90 days, the graded incorporation of insect protein meal led to a significant stepwise increase in final body weight, and a significant improvement of specific growth rate, feed conversion ratio, and protein efficiency ratio compared to the control treatment. Regardless of the incorporation level, the insect protein meal had no effects on fish whole-body composition and apparent digestibility coefficients of dry matter, protein, fat, phosphorus, and energy. Protein, phosphorus, and energy retention significantly increased in fish fed the diets with an insect protein meal. In conclusion, the yellow mealworm protein meal could effectively replace 100% of fishmeal in the diet of juvenile rainbow trout with positive effects on its overall zootechnical performance.

As men age, serum testosterone (T) concentrations decrease, as do fitness, strength and lean mass. Whether testosterone treatment confers additive benefit to reverse these changes when combined with exercise training in middle-to-older aged men remains unclear. We assessed the effects of T treatment and exercise, alone and in combination, on aerobic capacity (VO2peak), body composition and muscular strength in men 50-70yrs, waist circumference ≥95cm and low-normal serum T (6-14nmol·L−1). Participants (n=80) were randomised to AndroForte5® (Testosterone 5.0%w/v, 100mg/2mL) cream (T), or matching placebo (P), applied transdermally daily, and supervised centre-based exercise (Ex) or no additional exercise (NEx), for 12-weeks. Exercise increased VO2peak and strength vs non-exercise (VO2peak: T+Ex:+2.5, P+Ex:+3.2mL·kg−1·min−1, P<0.001; leg press: T+Ex:+31, P+Ex:+24kg, P=0.006). T treatment did not affect VO2peak or strength. Exercise decreased total (T+Ex:-1.7, P+Ex-2.3kg, P<0.001) and visceral fat (T+Ex:-0.1, P+Ex:-0.3kg, P=0.003), and increased total (T+Ex:+1.4, P+Ex:+0.7kg, P=0.008) and arm lean mass (T+Ex:+0.5, P+Ex:+0.3kg, P=0.024). T treatment did not affect total or visceral fat, but increased total (T+Ex:+1.4, T+NEx:+0.7kg, P=0.015), leg (T+Ex:+0.3, T+NEx:+0.2kg, P=0.024) and arm lean mass (T+Ex:+0.5, T+NEx:+0.2kg, P=0.046). T+Ex increased arm lean mass (T+Ex:+0.5kg vs P+NEx:-0.0kg, P=0.001) and leg strength (T+Ex:+31 vs P+NEx:+12kg, P=0.032) compared to P+NEx, with no other additive effects. Exercise training was more effective than T treatment in increasing aerobic capacity and decreasing total and visceral fat mass. T treatment at therapeutic doses increased lean mass but conferred limited additional benefit when combined with exercise. Exercise should be evaluated as an anti-ageing intervention in preference to testosterone treatment in men.
