Special Issue Information

Dear Colleagues,

Feed additives play a crucial role in aquaculture, significantly contributing to the health and growth of aquatic organisms. Studying these additives is essential for optimizing nutrition, improving feed efficiency, and ensuring the sustainability of aquaculture production. They can include vitamins, minerals, amino acids, enzymes, organic acids, essential oils, and probiotics, among others, each with specific functions, such as strengthening the immune system, increasing feed digestibility, and improving meat quality.

Furthermore, the proper use of feed additives can reduce the environmental impact of aquaculture by decreasing antimicrobial use and minimizing the nutrient and waste emissions polluting the waters. Research in this area is also vital to ensuring the safety of additives for both animals and end consumers. With a focus on the above, we invite contributions to the Special Issue titled "Advances in Aquaculture Feed Additives".

Popular foods such as sushi and sashimi depend on the quality of raw fish meat to maintain consumer satisfaction. Recently, dietary insect meal and insect-derived substances have been extensively studied for application in aquaculture as a protein alternative or immunostimulant. However, the impact of insect functional substances on the fish meat quality of teleosts remains unclear. Here, we investigated the influence of dietary inclusion of silkrose-BM, a novel bioactive polysaccharide derived from the silkworm, Bombyx mori, on the meat quality of yellowtail (Seriola quinqueradiata). This study was conducted by comparing two groups given different feeds, commercial EP and feeds containing Silkrose-BM (0.1%), after a culture period of six months in separate floating-net cages. The yellowtail were specifically cut into loins and several meat quality parameters were observed, including proximate, meat color changes, total collagen, drip loss, muscle histology, and gene expression (qRT-PCR). The results of the color-change analysis showed that discoloration of red muscle in the EP feed group occurred faster than in the silkrose-BM group, indicating an antioxidant property of silkrose-BM. Dietary silkrose-BM also significantly reduced drip loss and increased the total collagen content of yellowtail meat. Furthermore, qRT-PCR analysis showed that genes related to lipid and protein degradation were downregulated in the muscles of fish fed on silkrose-BM. In contrast, proximate analysis indicated no significant change in the nutritional composition of the meat between the groups. Taken together, our results suggest that dietary silkrose-BM could improve fish meat quality by minimizing protein denaturation and inhibiting lipid oxidation during fish meat storage. Full article

In the present study, Curcuma longa (CL) hydrolate and the probiotic Lactobacillus plantarum (LP) were provided as dietary supplements to Nile tilapia. One hundred ninety-two juvenile tilapias (2.25 ± 0.14 g and 4.5 ± 0.10 cm) were distributed in sixteen experimental units, and four experimental groups were established: CL [CUR]: fish fed a diet supplemented with CL hydrolate at 2.5%; probiotic [PRO]: a diet supplemented with LP; LP + CL [COMB]: diet supplemented with the LP strain cultivated in media supplemented with 2.5% CL hydrolate; and control [CTRL]: diet without supplementation. After 70 days, the final average weight was significantly greater in the PRO group (33.26 ± 1.12 g) than in the CTRL and CUR groups, whereas the specific growth rate was significantly greater in the PRO and COMB groups than in the CTRL and CUR groups. Feed conversion decreased significantly in the PRO group (1.03 ± 0.11). Dietary supplementation did not change the body composition of tilapia. Leukocyte and lymphocyte counts were greater in the PRO treatment than in the CTRL group. Compared with those in the CTRL group, total serum protein was significantly increased in the PRO group. Immunoglobulins were higher in the COMB and PRO groups. In the experimental challenge, all the fish in the treated groups presented lower cumulative mortality rates. The combination of LP and CL improved the growth parameters of Nile tilapia. Full article
