Popis: In northern China, the predominant food sources for abalone farming include fresh kelp, salted kelp, and formulated diets, and abalone can also endure prolonged starvation when food is scarce. While there is a dearth of comprehensive investigation into the effects of these feeding patterns on the temporal dynamics of enzyme activity, and intestinal microbiome of abalone. In this study, a total of 3600 juvenile Pacific abalones were allocated to 12 tanks, randomly divided into four groups based on the feeding patterns: fresh kelp (labeled as FK), salted kelp (SK), formulated feed (FF), and starved group (S). After a 60-day feeding trial, the results showed that abalone in the FK, SK, and FF groups exhibited significant positive effects on both weight and shell growth compared to the S group (P
