Intestinal impairment of the California yellowtail, Seriola dorsalis, using soybean meal in the diet

Intestinal Transcriptome Analysis Highlights Key Differentially Expressed Genes Involved in Nutrient Metabolism and Digestion in Yellowtail Kingfish (Seriola lalandi) Fed Terrestrial Animal and Plant Proteins

“…Interestingly, no significantly differentially expressed transcripts involved in inflammation were found in the RNA-Seq results, which support the lack of histological abnormality in this study. This result contrasts with studies on California yellowtail, S. dorsalis [23], Atlantic salmon, S. salar [28,46] and turbot, Scophthalmus maximus [47]. The differences with our finding might be related to the longer trial duration in those studies (56 days to 96 days) or the varying response in different species.…”

“…Plant-based ingredients (e.g., soybean, dehulled field pea, wheat and corn gluten) have proved to be useful as partial or even total replacements of FM in both omnivorous and carnivorous aquaculture species [16][17][18][19][20][21]. However, the presence of anti-nutritional factors (ANFs) (e.g., saponins, lectins, protease inhibitors, oligosaccharides) in plant ingredients can cause a number of negative impacts on the digestive physiology, health and metabolism of fish resulting in reduced productivity [22][23][24]. Thus, for fish nutrition research, it is very important to evaluate the potential use of terrestrial animal and plant protein sources in the diet.…”

Complete replacement of fish oil and fish meal in the diet of juvenile California yellowtail Seriola dorsalis

“…For fish fed any of the diets, there were no inflammatory responses suggesting that the diets did not elicit antigenic stimulation. Goblet cells were increased in the FMC fish and the cause could be multifactorial such as a characteristic of the species (Choi, 1996), microbiota changes (Kelly & Salinas, 2017), intestinal variation based on sampling site (Hur et al., 2016; Serradell et al., 2019), physical response to feed, intestinal transit time or the diet (Bansemer et al., 2014; Viana et al., 2019). Goblet cells produce mucus to protect intestinal mucous membranes and increased numbers result in more mucus production, an indicator of subacute inflammation (Matulic et al., 2020).…”

“…Goblet cells produce mucus to protect intestinal mucous membranes and increased numbers result in more mucus production, an indicator of subacute inflammation (Matulic et al., 2020). In CYT, replacement of fish meal with soybean meal has resulted in intestinal inflammation (Viana et al., 2019). In kingfish ( S. lalandi ), inclusion of soybean meal showed no intestinal signs of inflammation but did result in increased goblet cells (Bansemer et al., 2014).…”

Investigating Both Mucosal Immunity and Microbiota in Response to Gut Enteritis in Yellowtail Kingfish

“…Particular conditions such as enteritis (a gut inflammation) have become especially problematic in the farming of a number of different species such as Atlantic salmon ( Salmo salar ), zebrafish ( Danio rerio ), turbot ( Scophthalmus maximus ), yellowtail kingfish ( Seriola lalandi ), California yellowtail ( Seriola dorsalis ), pearl gentian grouper ( Epinephelus sp.) and common carp ( Cyprinus carpio L.) [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. Dietary components including high supplementation of soybean meal in the feed seem to play an important role in the emergence of this disease (or other related inflammatory disorders) in several species [ 7 , 8 , 9 , 10 , 14 , 15 ].…”
