“…Chemoreception of these systems is activated when substances dissolve in water; therefore, metabolites with low molecular weight, such as amino acids (AAs), can stimulate feed consumption (Carr et al, 1996;Derby & Sorensen, 2008;Kim & Cho, 2019;Morais, 2017). Various studies on regarding feed ingredient with high feed attractants and/or stimulants for fish have been conducted, but these ingredients vary greatly relying on the fish species and the concentration of the ingredients (Carr et al, 1996;Jeong et al, 2020Jeong et al, , 2022Tandler et al, 1982;Yacoob & Browman, 2007), implying that more in-depth research is needed for the cultivated fish species.…”

Dietary inclusion effects of various levels of jack mackerel meal (JMM) on growth, feed utilization, biochemical composition, and innate immune response of rockfish were determined. The control (Con) diet included 550 g/kg fish meal (FM). Ten, 30, 50, 100, 200, 400, 600, and 1000 g/kg of JMM were included in the Con diet, referred to as the JMM10, JMM30, JMM50, JMM100, JMM200, JMM400, JMM600, and JMM1000 diets, respectively. Eight hundred and ten fish (initial mean weight of 2.3 g) were distributed into 27 flow‐through tanks. The experimental diets were assigned to triplicate groups of fish. Fish were hand‐fed for 8 weeks. Weight gain of fish fed the JMM400 diet was statistically better than that of fish fed the Con, JMM10, JMM30, JMM50, JMM100, and JMM200 diets. Feed consumption of fish fed the JMM400 diet was statistically higher than that of fish fed the Con, JMM10, JMM30, and JMM50 diets. Dietary inclusion of JMM did not influence feed utilization, biochemical composition, and innate immune responses of fish. In conclusion, inclusion of JMM up to 400 g/kg of FM in diet improved growth and feed consumption of rockfish, and dietary optimum inclusion levels of JMM were estimated to be 396.7 and 403.1 g/kg based on regression analysis of weight gain and feed consumption, respectively.

“…The marine fish olive flounder ( Paralichthys olivaceus ) is a commercially popular aquaculture species, particularly in the Republic of Korea, Japan, China, and other East Asian countries. Olive flounder aquaculture ranked first in terms of production volume and economic value (43,813 metric tons and US $369 million in 2021) in the Republic of Korea [ 28 , 29 ]. Owing to its excellent taste, high market demand, and rapid growth rate, the olive flounder is also considered an ideal candidate for US land-based aquaculture [ 30 ].…”

“…The nutrient requirements of this species have been well defined, and commercial feeds are locally available and exported to other countries. Being a carnivorous species, commercial feed formulations for this species typically include high lipid levels (8%–12%) and antioxidants, such as BHT [ 29 , 31 ]. With the growing concern for safety and consumer-friendly seafood, this study was undertaken to assess muscle-specific BHT accumulation, toxicity, and its effects on the growth performance, body nutritional integrity, hematological characteristics, and nonspecific immunity in P. olivaceus .…”

Butylated hydroxytoluene (BHT) is a commonly used antioxidant added to animal/fish feed to limit lipid autoxidation and peroxidation. Although there have been reviews and reports of BHT toxicity in animals, limited information is available with respect to the toxic effects and accumulation of BHT due to oral exposure in aquaculture species. Therefore, 120 days of feeding trial was conducted to evaluate the effects of dietary BHT on the marine fish olive flounder Paralichthys olivaceus. Graded levels of BHT were added to the basal diet in increments of 0, 10, 20, 40, 80, and 160 mg BHT/kg, corresponding to 0 (BHT0), 11 (BHT11), 19 (BHT19), 35 (BHT35), 85 (BHT85), and 121 (BHT121) mg BHT/kg diets, respectively. Fish with an average weight of 77.5 ± 0.3 g ( mean ± SD ) were fed one of the six experimental diets in triplicate groups. Growth performance, feed utilization, and survival rate were not significantly affected by the dietary BHT levels among all experimental groups, whereas BHT concentration in the muscle tissue was found to increase in a dose-dependent manner up to 60 days of the experimental period. Thereafter, BHT accumulation in muscle tissue showed a declining trend among all treatment groups. Furthermore, the whole-body proximate composition, nonspecific immune responses, and hematological parameters (except triglycerides) were not significantly influenced by the dietary levels of BHT. Blood triglyceride content was significantly higher in fish fed the BHT-free diet compared to all other treatment groups. Thus, this study demonstrates that dietary BHT (up to 121 mg/kg) is a safe and effective antioxidant without exhibiting any adverse effects on the growth performance, body composition, and immune responses in the marine fish olive flounder, P. olivaceus.
