“…In considering combined growth and shell growth including shell length and width, FM up to 50% could be made with CBM in abalone diets without compromising growth performance. Improved shell length and width of abalone fed the CBM0 diet compared to that of abalone fed the CBM75 and CBM100 diets appeared to be closely related to the growth rate of abalone, agreeing with other studies (Dai & Cho, 2022a;Lebata-Ramos et al, 2021;Luo et al, 2013;Zhao et al, 2018) explaining the positive relationship between shell growth and carcass weight versus growth rate of abalone. Unlike these studies, however, abalone-fed diets replacing FM with soybean meal (Yu et al, 2022), tuna viscera fermented by Lactobacillus bulgaricus (Lee et al, 2004), and tunic meal of sea squirt (Baek & Cho, 2022b) produced no noticeable difference in shell growth.…”

This study aims to assess the effect of replacing anchovy meal with chicken by‐product meal (CBM) in juvenile abalone (Haliotis discus hannai) feed. Five diets were formulated to contain 0 (CBM0), 25 (CBM25), 50 (CBM 50), 75 (CBM75), and 100% (CBM100) CBM in replacement to 24% fish meal (FM). Dried Saccharina japonica, which is the natural food for this species of abalone was also prepared. Each diet was fed to triplicate groups of abalone. 1260 abalone assigned into eighteen cages were fed for 16 weeks. After the 16‐week feeding trial, 30 abalones from each cage were exposed to air for 24 h, and survival was monitored for 7 days. Results showed that weight gain and specific growth rate of abalone fed the CBM0 (185.4 ± 12.83% and 0.93 ± 0.040%/day, respectively) diet were significantly (p < 0.04 for both) higher than those of abalone fed the CBM100 (139.0 ± 6.36% and 0.78 ± 0.024%/day, respectively) diet. Shell length and width of abalone fed the CBM0 diet were significantly (p < 0.003 and p < 0.02, respectively) longer and wider than those of abalone fed the CBM75 and CBM100 diets. Survival of abalone during the 7‐day post‐observation period after the 24‐h air exposure exhibited no remarkable (p > 0.1 for Log Rank and Wilcoxon tests) difference among all formulated diets according to the analysis of the Kaplan–Meier survival curve. In conclusion, CBM can replace FM up to 50% in an abalone diet without compromising growth performance and survival.
