Our investigation was to study the effect of protein levels 25% and 30% within each level protein that four levels of Digestarom ® P.E.P. (0.00, 0.01, 0.02 and 0.03%) on growth performance, feed utilization and economical evaluation of red tilapia fingerlings. Red tilapia fingerlings were fed on eight experimental diets composed of two protein levels a 25 % and 30% crude protein within each protein levels supplemented with Digestarom ® P.E.P. at four levels (0.00, 0.01, 0.02 and 0.03%).The results indicated that protein levels 30% and Digestarom ® at 0.02% had positive effect on the final weight, weight gain, specific growth rate, feed conversion ratio and feed efficiency ratio. The interactions of Digestarom® and protein levels have a significantly higher in growth performance, feed utilization, survival rate and economical evaluation.It could be concluded that the best Digestrom ® levels was 0.02% Digestrom ® in each protein levels 25 and 30 % in terms of growth performance, feed utilization, survival rate and economic evaluation.

“…At the end of the trial, whole-body protein content was enhanced by PEP supplementation and likely driven by increased protein and energy retention (Table 3). Although previous studies have shown mixed effects of PEO supplementation on nutrient retention (see review by Teves & Ragaza, 2016), the positive effect of the supplement used in the present study was such that fish fed LFM+PEP showed similar energy and protein retention to fish fed the HFM diet. PEOs are known to stimulate gut secretions, which increases nutrient utilization and protein synthesis and, ultimately, fish protein content (Freccia et al, 2014).…”

The inclusion of phytogenics in fish feed is a promising strategy to compensate for the negative performance effects of replacing fishmeal (FM) with vegetable sources. The present work assessed the interactive effects of different dietary FM levels (22.5 and 10% of formulation) and the supplementation of a commercial blend of anise, citrus, and oregano essential oils (Digestarom PEP M.G.E 150) on European sea bass, Dicentrarchus labrax growth performance, nutrient utilization, gut morphology, antioxidant status, and immunological response over a 60‐day growth trial. Results showed decreased growth and protein efficiency ratio and increased feed conversion ratio with a low dietary FM level. In contrast, supplementation of the phytogenic product demonstrated improved performance and nutrient utilization together with increased protein and energy retention. Supplementation with the plant essential oils fully compensated for the negative intestinal changes observed in sea bass fed a low‐FM diet but showed little improvement in fish immunological response, except for the 30% increase in lysozyme activity observed in fish fed the low FM‐supplemented diet compared to those fed the standard high‐FM diet. Overall, this study supports the use of this phytogenic product in low‐FM diets as a possible tool to decrease feed costs associated with FM without compromising fish performance, nutrient utilization, and health.

“…Fish consumption from aquaculture is projected to reach 112 million tonnes in 2025 (FAO, ). The growing demand for fish food products heighten the pressure on supplying of feed ingredients, especially for fishmeal (FM) (Ronaldw, ; Teves & Ragaza, ). Therefore, aquaculture constitutes a threat to world fish stocks because of aquaculture, especially for carnivorous fish's reliance on FM and thus on reduction fisheries (Chamberlain, ), which makes FM expensive and limited supply.…”

Effects of fishmeal replacement by Tenebrio molitor meal on growth performance, antioxidant enzyme activities and disease resistance of the juvenile pearl gentian grouper (Epinephelus lanceolatus ♂ × Epinephelus fuscoguttatus ♀ )

A 50-day feeding trial was conducted for juvenile pearl gentian grouper (Epinephelus lanceolatus ♂ 9 Epinephelus fuscoguttatus ♀) to determine the optimal amount of Tenebrio molitor meal (TM) that could replace fishmeal (FM) in feeds without reducing growth performance, antioxidant enzyme activities and resistance. Six isonitrogenous and isolipidic diets were formulated with TM replacing 0% FM respectively. Each diet was randomly divided into triplicate groups with 30 juveniles (initial weight 6.60 AE 0.00 g). After feeding trail, fish were challenged by Vibrio harveyi for 7 days.The results showed that each treatment had better survival rate between 96.67% and 100%. Fish fed with control and T6 diet showed lower final weight and weight gain rate as compared to other diets. The feed conversion ratio of fish fed on T12 and T18 diet had no significant difference compared to control diet. As compared to control diet, other diets had no significant differences on specific growth rate and temperature growth coefficient. Fish fed with T6 diet had highest liver glutathione reductase activities. No significant differences were observed in liver superoxide dismutase activities in fish fed with T6, T12, T25, T31 and control diet.Fish fed on T18 diet had lowest hepatic malondialdehyde contents and a highest relative per cent survival. According to a broken-line model, the recommended substituted ratio of TM for FM was estimated to be 12.3% for grouper obtaining maximum WGR, corresponding to additive amount of TM is 4.92%.
