Special Issue Information

Dear Colleagues,

Modern aquaculture follows global guidelines for environmentally friendly ways to turn non-human edible feedstuffs into high-quality protein for people to eat, helping the growth of ornamental species and bringing back wild aquatic animal populations. Nevertheless, the limited nature of conventional feed ingredients, such as fish meal and fish oil, as well as their economic and environmental impacts, has underscored the urgent need for sustainable ingredients. This Special Issue, "Alternative Feeds for Aquatic Animals", explores innovative solutions that enhance sustainability, reduce dependence on traditional feed ingredients, and improve aquaculture efficiency. The focus encompasses plant-based proteins, insect meals, single-cell proteins, algae, and industrial by-products, among others. Contributions address the nutritional quality, digestibility, growth performance, health impacts, and environmental footprints of alternative feeds. Special attention is given to the implications of these feeds on gut microbiota, immune responses, and product flesh quality in aquatic species. By bringing together the latest research, this Special Issue aims to promote sustainable aquaculture practices that protect the sector's economy and the environment and improve food security worldwide.

Fish meal (FM) and fish oil (FO) are vital components commonly used in feed formulations. However, their supply, which generally comes from capture fisheries, is being exhausted, necessitating the exploration of sustainable alternatives. In a two-part study, the first part evaluated the FM and FO derived from smoked salmon by-product (SSBP) over a 12-week accelerated shelf-life test, comparing their lipid oxidation, amino acid, and fatty acid profiles to those of commercial whitefish meal and oil. In the second part, the SSBP FM and FO were then included in three experimental feeds at 25%, 50%, and 100% inclusion levels. These feeds were tested on juvenile striped bass (Morone saxatilis) cultured in a recirculating aquaculture system (RAS). The results indicated that the quality of SSBP FM and FO was lower than the commercial product (less amino acids (23.98% vs. 60.30%) and omega-3 fatty acids (9.46% vs. 26.6%), respectively). SSBP FO exhibited high initial peroxide value (21.00 ± 0.00 meq/kg oil), with gradually increasing total oxidation value and p-Anisidine value during storage. Regarding the feeding trial, all fish showed signs of Mycobacterium marinum infection after one month. While there was no significant difference in feed palatability (p > 0.8559), the feed conversion ratio was less efficient for the 100% SSBP feed (1.44 ± 0.14) compared to commercial feed (1.36 ± 0.13), but these differences were not statistically significant. This study suggests that SSBP FM and FO can be used as supplements at lower levels (25% and 50%) without negatively affecting growth, feed efficiency, or survival. Our findings may be useful for enabling beneficial collaborations between smoked salmon processors, feed manufacturers, and striped bass farmers, therefore contributing to sustainability in aquaculture practices.
