“…In the case of salmonids, SBM cause morphological and functional changes in the intestine such as widening of the lamina propria (Baeverfjord and Krogdahl, 1996), inducing enteritis in the distal intestine (Urán et al, 2008b) and shortening villi and microvilli (van den Ingh et al, 1991). These changes in intestinal morphology in fish fed SBM-based diets have been reported also for other species such as common carp (Cyprinus carpio) (Urán et al, 2008a), rainbow trout (Oncorhynchus mykiss) (Nordrum et al, 2000), gilthead sea bream (Sparus aurata) (Bonaldo et al, 2008) and Nile tilapia (Mahmoud et al, 2014, Ismaiel et al, 2015. These changes in the intestinal morphology as a consequence of feeding SBM-based diets seem to be species specific, just as its ability to recover from these changes when fed a non-SBM-based diet.…”

“…Plant based ingredients in the diet are the major determining factor for intestinal length, and in general herbivorous fish tend to have longer intestines than carnivorous fish (Nagase, 1964). Functionally, the proximal part of the intestine is the G e n e r a l i n t r o d u c t i o n | 13 main nutrient-absorbing region (Nordrum et al, 2000). The lumen in this region contains high nutrient concentrations, typically low numbers of bacteria, and is lined by an absorbing region (Nordrum et al, 2000).…”

“…Diets containing a high level of soybean meal (SBM) may induce an inflammatory response in the distal intestinal epithelium of carnivorous fish species (Krogdahl et al, 2003, Nordrum et al, 2000. Baeverfjord and Krogdahl (1996) salmon are believed to be less adapted to diets containing ingredients of plant origin (Urán, 2008).…”

A nanometric revolution is underway, promising technical innovations in a wide range of applications and leading to a potential boost in environmental discharges. The propensity of nanoparticles (NPs) to be transferred throughout trophic chains and to generate toxicity was mainly assessed in primary consumers, whereas a lack of knowledge for higher trophic levels persists. The present study focused on a predatory fish, the European eel (Anguilla anguilla) exposed to gold NPs (AuNPs; 10 nm, polyethylene glycol-coated) for 21 d at 3 concentration levels in food: 0 (NP0), 1 (NP1), and 10 (NP10) mg Au kg −1. Transfer was assessed by Au quantification in eel tissues, and transcriptomic responses in the liver and brain were revealed by a high-throughput RNA-sequencing approach. Eels fed at NP10 presented an erratic feeding behavior, whereas Au quantification only indicated transfer to intestine and kidney of NP1-exposed eels. Sequencing of RNA was performed in NP0 and NP1 eels. A total of 258 genes and 156 genes were significantly differentially transcribed in response to AuNP trophic exposure in the liver and brain, respectively. Enrichment analysis highlighted modifications in the immune system-related processes in the liver. In addition, results pointed out a shared response of both organs regarding 13 genes, most of them being involved in immune functions. This finding may shed light on the mode of action and toxicity of AuNPs in fish.

The worldwide-industrialized production of Atlantic salmon (Salmo salar) has increased dramatically during the last decades, followed by diseases related to the on-going domestication process as a growing concern. Even though the gastrointestinal tract seems to be a target for different disorders in farmed fish, a description of the normal intestinal status in healthy, wild salmon is warranted. Here, we provide such information in addition to suggesting a referable anatomical standardization for the intestine. In this study, two groups of wild Atlantic salmon were investigated, consisting of post smolts on feed caught in the sea and of sexually mature, starved individuals sampled from a river. The two groups represent different stages in the anadromous salmon life cycle, which also are part of the production cycle of farmed salmon. Selected regions of gastrointestinal tract were subjected to morphological investigations including immunohistochemical, scanning electron microscopic, and morphometric analyses. A morphology-based nomenclature was established, defining the cardiac part of the stomach and five different regions of the Atlantic salmon intestine, including pyloric caeca, first segment of the mid-intestine with pyloric caeca, first segment of the mid-intestine posterior to pyloric caeca, second segment of the mid-intestine and posterior intestinal segment. In each of the above described regions, for both groups of fish, morphometrical measurements and regional histological investigations were performed with regards to magnitude and direction of mucosal folding as well as the composition of the intestinal wall. Additionally, immunohistochemistry showing cells positive for cytokeratins, α-actin and proliferating cell nuclear antigen, in addition to alkaline phosphatase reactivity in the segments is presented.
