Dietary selenium regulates the diversity and stability of microbial communities in stomach and intestine of rabbitfish (Siganus oramin)

Effects of polystyrene nanoplastics on apoptosis, digestive enzymes, and intestinal histological structure and flora of swamp eel (Monopterus albus)

“…13,14 It also has an important role in the development and regulation of the immune system of the host. 15,16 NPs can induce excessive oxidative stress in the body, 17,18 interfere with normal nutrient absorption and metabolism, and directly disrupt the intestinal flora of aquatic organisms, such as zebrafish, which can in turn lead to intestinal inflammation. [19][20][21] Monopterus albus, commonly known as the rice eel or swamp eel, is a freshwater carnivorous fish that is widely distributed in muddy ponds, marshes and rice fields throughout Asia.…”

Variations and Interseasonal Changes in the Gut Microbial Communities of Seven Wild Fish Species in a Natural Lake with Limited Water Exchange during the Closed Fishing Season

“…Although gut microbes play a crucial role in fish nutrition and metabolism, their composition and abundance are strongly influenced by many direct and indirect factors. Many studies have shown that gut microbial communities vary according to host individual development [21], diet [12,22], environment [19,23], and host genetics and phylogeny, which refer to fish populations from different geographic clusters having different gut microbiomes and fish genotypes correlating with gut microbiomes, with the more genetically distinct populations exhibiting greater differences in gut microbiomes [24,25]. However, previous studies have focused on single species in limited environments, such as fish in farmed ponds or under laboratory conditions and fed specific foods [12,15,18,26].…”
