“…Over the last decade, the farming of largemouth bass has progressed from feeding animals with trash fish to feeding them with artificial diets containing high levels of FM and protein, but low starch [ 42 , 43 ]. As well as the inclusion of protein from traditional sources such as soy or territorial animal protein, various novel protein sources, such as Clostridium autoethanogenum protein [ 31 , 44 , 45 ], cottonseed protein concentrate [ 32 ], and Methylococcus capsulatus (FeedKind ® ) [ 19 ], have been successful in partial replacing FM in diets of largemouth bass. Although several studies have shown that FM inclusion can be reduced to 15–20% in the formulation without negative effect on growth performance [ 31 , 32 ], the amount of FM in largemouth bass commercial diets is generally kept at 30–50%.…”

A 10-week growth study was conducted to evaluate the effect of a natural gas fermentation bacterial meal (FeedKind®, FK) as a fishmeal (FM) alternative in largemouth bass (Micropterus salmoides) (48.0 ± 0.03 g). Four isonitrogenous and isoenergetic diets were formulated including one commercial control (C, 42% FM) and three experimental diets with gradient FK of 3% (FK3, 29%FM), 6% (FK6, 26%FM) and 9% (FK9, 23%FM), respectively. FK-fed groups showed significantly higher SR than that of C group. The WGR and SGR of fish fed FK3 and FK6 were significantly higher than those of FK9, but not statistical different from the C group. FK-fed groups showed higher apparent digestibility coefficients of dry matter and nutrients. Further, FK-fed groups increased the ratio of SOD/MDA in the plasma and liver, and the upregulation of intestinal Keap1 and downregulation of HIF1α was found in FK3. Furthermore, FK-fed groups showed higher microbial richness and diversity. Pearson correlation analysis found that antioxidant relevant biomarkers were negatively correlated with the relative abundance of certain potential beneficial bacteria. In conclusion, supplemented up to 3–6% FK replacing FM in a low FM diet of largemouth bass could increase growth, survival rate, antioxidant capacity, and improve gut microbiota.

“…Over the past few decades, the availability of plant‐based protein sources such as soybean meal and corn gluten meal and animal by‐products such as meat and chicken meals has been widely investigated (Gatlin et al, 2007; Hardy, 2010; Shukla et al, 2019). Furthermore, in recent years, research on new raw materials such as insect meal (Mente et al, 2022; Takakuwa, Tanabe, et al, 2022; Yamamoto et al, 2022) and bacterial cell meal (Adeoye et al, 2021; Zhang et al, 2022; Zhu et al, 2022) has also progressed, and attempts to further reduce the usage of FM continue to expand. However, it has been reported that these substitutes have certain disadvantages, such as decreased growth performance (Burr et al, 2012; Chen et al, 2019), low nutrient digestibility (Drew et al, 2007) and feed intake (Arndt et al, 1999; Kissil et al, 2000), increased anti‐nutrient factors (Francis et al, 2001) and deformation of intestinal tissues (Krogdahl et al, 2003; Yamamoto et al, 2007), when included in the feed in excess of permissible levels.…”

We replaced fish meal (FM) with porcine blood meal (BM) in red sea bream (Pagrus major) diets to examine the influence on growth performance. Four experimental diets were prepared to be isonitrogenous and isolipidic by replacing 0%, 10%, 20% and 30% FM protein with BM (BM0, BM10, BM20 and BM30, respectively). After the 8-week feeding trial, the final mean body weight, weight gain, specific growth rate, daily feeding rate, condition factor and survival rate were not significantly different among the treatments (p > 0.05). However, feed efficiency tended to lower linearly as the dietary BM level increased, and no significant difference was observed between the BM20 and BM0 groups (p < 0.05). The protein digestibility in the BM20 and BM30 groups decreased significantly compared with that in the BM0 group (p < 0.05).Fat digestibility decreased significantly in the BM30 group than in other treatment groups (p < 0.05). The total serum protein and total cholesterol concentrations in the BM30 group were the highest among all treatment groups. In conclusion, BM can replace up to 20% of FM in the red sea bream diet without adversely affecting growth performance.

“…In M. salmoides, the replacement of fishmeal with CAP did not affect its growth performance and whole-body composition but increased the digestive capacity and antioxidant index. The optimal CAP replacement level was 49.80% with a maximum WGR of juvenile M. salmoides (31). Lu et al found that there is no negative effect on the growth performance and liver health of M. salmoides when the level of CAP replacing fishmeal is less than 50%, and excessive CAP inclusion may damage liver health (29).…”

“…CAP has been used in several aquaculture species, including Acanthopagrus schlegelii, Micropterus salmoides, Cyprinus carpio var. Jian, and L. vannamei, with the effect of improving growth performance, feed utilization, anti-oxidation, intestinal health, and immune response (26)(27)(28)(29)(30)(31). In a basal diet containing 560 g/kg FM, CAP could substitute 30% FM without adverse effects on growth, intestinal histology, and immunity, while higher FM substitution decreased the growth and flesh quality of L. vannamei (27,32).…”

The shortage of fishmeal (FM) resources limits the healthy development of aquaculture. Developing new protein sources to replace FM in aquatic feeds is an effective measure to alleviate this situation. However, the application effect of new protein sources is greatly affected by water salinity, which is an important parameter of aquaculture. In this study, the growth, disease resistance, and intestinal digestion, immunity, and microbiota structure of Litopenaeus vannamei (initial weight: 0.38 ± 0.01 g) fed on Clostridium autoethanogenum protein (CAP) or not at three different water salinities (15 ‰, 30 ‰, and 45 ‰) were compared, aiming to explore the effects of dietary CAP on shrimp when suffering different salinity stresses. The results showed that the growth performance, feed utilization, and survival rate (SR) after pathogen challenge of L. vannamei could be significantly improved by dietary CAP when compared with the control at the same salinity and they were also significantly affected by salinity changes when L. vannamei was fed on the same protein source. With the increase in salinity, obvious upregulation was observed in the activities and gene expression of digestive enzymes both in L. vannamei fed on FM and CAP, with significantly higher levels in L. vannamei fed on CAP than in those fed on FM at the same salinity. Meanwhile, the expression levels of immune genes in the CAP group were significantly higher than those in the FM group at different salinities. The intestinal microbiota analysis showed that CAP could increase the relative abundance of beneficial bacteria and decrease the relative abundance of harmful bacteria in the intestine of L. vannamei at the phylum, family, and genus levels, and it was more affected by salinity changes when compared with FM. Besides, the changes in salinity and protein sources led to different changes in the intestinal microflora function of L. vannamei. In sum, this study indicated that CAP could improve the growth, disease resistance, digestive capacity, and intestinal microflora of L. vannamei with a much more intense immune response and enhance its ability to cope with salinity stress.
