However, due to supply and price fluctuations, coupled with environmental issues in FM production, FM is no longer a sustainable source from economic and environmental perspectives. Recently, high-protein corn co-products, such as high-protein distiller's dried grains (HP-DDG) and corn-fermented protein (CFP) have attracted much attention as alternative protein ingredients. Therefore, a 12-week feeding trial was carried out to assess a CFP product on growth performance, feed utilization, antioxidant and non-specific immune responses, and intestinal histopathology as an FM replacer in the diets of Atlantic salmon parr, <i>Salmo salar</i>. Five isonitrogenous (51% crude protein) and isocaloric (22.3 MJ kg⁻¹) diets were formulated to substitute 0% (CFP₀), 25% (CFP₂₅), 50% (CFP₅₀), 75% (CFP₇₅), and 100% (CFP₁₀₀) of FM with a corresponding amount of CFP. The experimental diets were fed to satiation, three times daily, to quadruplicate groups of Atlantic salmon parr (11.6 ± 0.06 g). At the end of the 12-week feeding trial, the final weight, weight gain, and survival of fish did not significantly differ between treatment groups. However, in fish fed CFP100, both the feed conversion ratio (FCR) and the protein efficiency ratio (PER) exhibited significant differences in comparison with those of fish fed other treatments, with FCR being significantly higher and PER being significantly lower. Quadratic regressions of PER and FCR against the dietary CFP inclusion levels suggest that the optimal substitution level was between 18.6% and 25%. Parameters related to antioxidant and non-specific immune responses were not significantly impacted by the dietary treatment except for lysozyme activity. Lysozyme activity exhibited a significant increase in fish fed CFP₂₅ in contrast to the fish fed CFP₇₅. With respect to distal intestinal morphology, fish fed CFP₀ and CFP₂₅ exhibited significantly higher fold height, while fish fed CFP₅₀ showed a reduction in fold height. The mean score of evaluated histopathology features was not significantly influenced by the dietary CFP levels. In conclusion, based on the results of the analysis of variance (ANOVA), replacing 50% of FM with CFP can be implemented without any detrimental effects on growth performance, feed utilization, non-specific immunity, and intestinal health during the parr phase of Atlantic salmon production.</p>","PeriodicalId":17284,"journal":{"name":"Journal of The World Aquaculture Society","volume":"56 2","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jwas.70020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that the 1.0% inulin diet resulted in the highest specific growth rate, weight gain, and survival rate. An increase in antioxidative and immune enzyme activities suggested improved health conditions at optimal inulin levels, evidenced by the reduction of malondialdehyde content and potentiation of enzymes like superoxide dismutase and lysozyme. Microbiome analysis via 16S rRNA sequencing showed a significant shift in gut bacterial populations, with an increase in beneficial bacteria such as <i>Xanthomarina</i> and a reduction in pathogenic <i>Vibrio</i> and <i>Flavobacteria</i> in inulin-supplemented groups. Higher dietary inulin increased gut microflora diversity significantly in the T2 group. Metabolomic analysis showed distinct pathway enrichment and differential metabolite regulation, linking inulin intake to significant alterations in lipid metabolism, including pathways like bile secretion, arachidonic acid metabolism, steroid hormone biosynthesis, and ABC transporters. Furthermore, correlation and KEGG enrichment analyses revealed intricate interactions within the shrimp metabolic network, pointing to compensatory and regulatory mechanisms in response to inulin supplementation.

This project specifically looked at how <i>Saccharina latissima</i> can be grown in the Gulf of Alaska to reach that goal. There were three major aspects of the research: (1) optimize nursery production and seeding lines for outplanting; (2) design an economical, modular outplanting structure; and (3) develop methods to efficiently harvest the product. Farm designs were based on catenary structures and the use of spreader bars with variable spacing of grow-lines and line types. The spacing of the grow-lines makes a difference in the yield. Grow-line spacing of ≥1.5 m showed about a 50% increase in production (kg m⁻¹). There was no statistical difference in the growth of <i>Saccharina latissima</i> whether in the middle or the outside of the array, but the line type and perhaps line thickness can make a difference in yield. Sagging caused by the weight of the mature fronds resulted in lower growth at depth. Various harvesting approaches for mature kelps were tested by collaborating farmers. One promising innovation is the use of large bags with mesh for temporarily holding the freshly harvested fronds in seawater. Although the weight of the fronds on the grow-lines causes the lines to sink, the bags packed with the harvested fronds float, allowing for temporary storage before loading to a vessel heading to port and processing. Another advance in harvesting is a specially built harvest vessel, the <i>Harvest Buddy</i>, allowing a more mechanized and faster way to harvest.
