Special Issue Information

Dear Colleagues,

Over several decades, aquaculture has emerged as a key industry, bridging the gap between fish demand and supply. However, due to the global population increase and concerns regarding feed sustainability, species health management, and climate change, the sustainability of aquaculture is being threatened. Nutritional interventions and dietary optimization have proven to be effective in addressing these concerns, enhancing production efficiency, and improving animal welfare.

This Special Issue invites submissions that explore how innovative nutritional strategies can address key challenges in aquaculture. We are particularly interested in research on new feed formulations, alternative ingredients, and targeted nutritional management practices. Studies examining the responses of aquaculture species to various dietary interventions are also highly encouraged.

We welcome both original research and comprehensive reviews that provide insights into these areas. Your contributions will advance the understanding of how effective nutritional management can foster a more resilient and sustainable aquaculture industry in a rapidly changing world.

Prof. Dr. Seunghyung Lee

Abstract
This experiment was to investigate the effects of feeding frequency on the growth performance, body composition, and intestinal health of hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatu ♂).

This experiment was to investigate the effects of feeding frequency on the growth performance, body composition, and intestinal health of hybrid grouper (Epinephelus fuscoguttatus♀ × E. lanceolatu ♂). Fifty-six days of feeding with four different feeding frequencies (1 time/day, 2 times/day, 3 times/day, and 4 times/day) were conducted on groupers with an initial body weight of 11.51 ± 0.02 g. The results show the following: (1) Weight gain rate (WGR) and specific growth rate (SGR) of the groupers in the 1 time/day group were significantly lower than in other groups (p < 0.05). (2) Superoxide dismutase (SOD) had the lowest value in the 1 time/day group, significantly lower than the 2 times/day and 4 times/day groups, catalase showed an upward trend, and the 4 times/day group was significantly greater than the other groups (p < 0.05). The total antioxidant capacity (T-AOC) and glutathione peroxidase (GPX) activities in the 1 time/day group were significantly lower than in the other groups (p < 0.05). (3) The increase in feeding frequency led to a significant increase in the expression levels of cat and il-6 (p < 0.05). In summary, appropriate feeding frequency can promote growth and enhance the antioxidant capacity of the fish’s gut. We recommend a best feeding frequency of 2 times/day. Full article
