Growth rate, feed efficiency, and mortality were not adversely affected by reducing the level of herring meal in an open formula dry-pellet diet fed to rainbow trout (Salmo gairdneri) in aquaria through which 80–90% of the effluent water was recirculated. The herring meal was reduced from 35 to 18%, and the level of soybean meal increased from 10 to 39%. The fish gained 5.5 and 5.4 kg/100 fish from 8 to 40 wk of age on the high and low herring meal diets, respectively. Deletion of brewers' yeast, corn fermentation extractives, and whey powder from the diet with the higher level of herring meal increased weight gain to 7.0 kg/100 fish. When the fermentation by-products were removed from the diet with the lower level of fish meal the gain was reduced to 4.8 kg/100 fish. All the diets contained 4% of soybean or rapeseed oil or a marine oil; the type of oil did not influence the gains, but the conversion of feed to gain was most efficient for the diet containing the marine oil. The apparent digestibilities of the proximate components of three of the diets suggested that the fermentation by-products were not as digestible to the fish as the other components of the diet.

Abstract Seriola lalandi is an important species for aquaculture, due to its rapid growth, adaptation to captivity and formulated diets, and high commercial value. Due to the rise in fish meal (FM) price, efforts are made to replace it partially or entirely with vegetable meals in diets for carnivorous fish. The use of prebiotics when feeding vegetable meals has improved fish health. In this study, four experimental diets were assessed in juveniles, the control diet consisted of FM as the main protein source, the second diet included 2% GroBiotic®-A (FM-P), the third included FM with 25% replacement by soybean meal (SM25), and the fourth consisted in SM25 with 2% of GroBiotic®-A (SM25-P). RNA-seq of the liver tissue was performed, followed by differential expression analysis and functional annotation to identify genes affected by the diets. Growth was not affected by this level of FM replacement, but it was improved by the prebiotic. Annotation was achieved for 78,826 transcripts, of which 135 were up-regulated and 78 down-regulated among all treatments compared to the control. Transcriptomic profiles of control samples were clustered with those from fishes fed SM25 and SM25-P diets, and the most differentiated group was that one fed the FM-P diet. SM25-P showed the least amount of differentially expressed genes, maintaining general transcriptomic profiles of control diet in the liver, therefore this diet is a potential economic alternative to the FM diet, for S. lalandi juveniles. Assessment of the effects of this diet along the digestive tract is recommended.
