Bottom Line: The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus asotus.Broken line regression analysis of WG suggested that the maximal dietary inclusion level for FBPM as a FM replacer could be 6.3% without any adverse effects on whole body composition and on serological characteristics.Therefore, these results may indicate that the maximal dietary inclusion level of FBPM as a FM replacer could be 6.3% in juvenile Amur catfish.

ABSTRACT
The present experiment was conducted to evaluate the efficacy of dietary fermented by-product of mushroom, Pleurotus ostreatus, (FBPM) as a fish meal (FM) replacer in juvenile Amur catfish, Silurus asotus. A total number of 225 fish averaging 5.7±0.1 g (mean±standard deviation) were fed one of the five experimental diets formulated to replace FM with FBPM at 0%, 5%, 10%, 20%, and 30% (FBPM0, FBPM5, FBPM10, FBPM20, and FBPM30, respectively). At the end of eight weeks of the experiment, average weight gain (WG) of fish fed FBPM0 or FBPM5 were significantly higher than those of fish fed FBPM20 or FBPM30 diets (p<0.05). However, there was no significant differences in WG among the fish fed FBPM0, FBPM5 or FBPM10, and between fish fed FBPM10 or FBPM20, and also between those fed FBPM20 or FBPM30 diets. Lysozyme activity of fish fed FBPM0 or FBPM5 were significantly higher than those of fish fed FBPM10, FBPM20 or FBPM30 diets (p<0.05). The chemiluminescent response of fish fed FBPM5 was significantly higher than those of fish fed FBPM0, FBPM20 or FBPM30 diets (p<0.05). Broken line regression analysis of WG suggested that the maximal dietary inclusion level for FBPM as a FM replacer could be 6.3% without any adverse effects on whole body composition and on serological characteristics. Therefore, these results may indicate that the maximal dietary inclusion level of FBPM as a FM replacer could be 6.3% in juvenile Amur catfish.

Mentions: Growth performance of Amur catfish, Silurus asotus, fed different levels of dietary fermented mushroom by-product, Pleurotus ostreatus, as a FM replacer is shown in Table 2. The average WG of fish fed FBPM0 or FBPM5 were significantly higher than those of fish fed FBPM20 or FBPM30 (p<0.05). However, there was no significant differences in WG among the fish fed FBPM0, FBPM5, or FBPM10, and between fish fed FBPM10 or FBPM20, and also between those fed FBPM20 or FBPM30. The SGR of fish fed FBPM0, FBPM5, FBPM10, or FBPM20 were significantly higher than that of fish fed FBPM30 diet (p<0.05). The FE and PER of fish fed FBPM0 or FBPM5 were significantly higher than that of fish fed FBPM30 (p<0.05). The HSI of fish fed FBPM5 was significantly higher than that of fish fed FBPM30 (p<0.05). However, there were no significant differences in SGR, FE, PER, or HSI among fish fed FBPM0, FBPM5, FBPM10, or FBPM20 diets (p<0.05). Also, no significant differences were found in survival rate of fish fed any of the experimental diets (p<0.05). Broken line analysis of WG indicated that FBPM could replace 6.3% of FM without any adverse effects on growth performance of Amur catfish, Silurus asotus (Figure 1).
