“…Digestion is a very complex process that relies on both endocrine and neuronal systems (Olsson and Holmgren, 2001; Holmgren and Olsson, 2009), including a great number of signal molecules, namely neuro-hormonal modulators affecting fish digestion and feeding behaviour (Holmgren and Olsson, 2009; Serna-Duque and Esteban, 2020; Blanco et al ., 2021). Intestinal motility is involved in the breakdown and transport of food and is fundamental for nutrient intake (Gräns and Olsson, 2011). Any disorder in intestinal motility caused by pathogens or inappropriate diet results in the fish obtaining less nutrients from food.…”

Parasites and the neuroendocrine control of fish intestinal function: an ancient struggle between pathogens and host

et al. 2022

Most individual fish in wild and farmed populations can be infected with parasites. Fish intestines can harbour protozoans, myxozoans and helminths, which include several species of digeneans, cestodes, nematodes and acanthocephalans. Enteric parasites often induce inflammation of the intestine; the pathogen provokes changes in the host physiology, which will be genetically selected for if they benefit the parasite. The host response to intestinal parasites involves neural, endocrine and immune systems and interaction among these systems is coordinated by hormones, chemokines, cytokines and neurotransmitters including peptides. Intestinal fish parasites have effects on the components of the enteric nervous and endocrine systems; mechanical/chemical changes impair the activity of these systems, including gut motility and digestion. Investigations on the role of the neuroendocrine system in response to fish intestinal parasites are very few. This paper provides immunohistochemical and ultrastructural data on effects of parasites on the enteric nervous system and the enteric endocrine system in several fish–parasite systems. Emphasis is on the occurrence of 21 molecules including cholecystokinin-8, neuropeptide Y, enkephalins, galanin, vasoactive intestinal peptide and serotonin in infected tissues.

“…Any disorder in intestinal motility caused by pathogens or inappropriate diet results in the fish obtaining less nutrients from food. Moreover, motility is a well-coordinated process that relies on intrinsic and extrinsic factors including the innate properties of the smooth muscles, hormones and nerves (Gräns and Olsson, 2011).…”

“…This result was similar with the study on a cyprinid fish Culter alburnus (Cao et al., 2011), which exhibited the thinning of the muscular layer in its posterior intestine. The decreased thickness of the intestinal muscular layer could weaken intestinal peristalsis (Ferreira et al., 2016), thus abating the digestion function (Gräns & Olsson, 2011; Olsson & Holmgren, 2011). The thinnest muscularis in the posterior intestine of the koi carp may also be closely related to its poor digestive capacity (Fang & Zhou, 1997).…”

In this study, the delimitation of intestine segments of koi carp (Cyprinus carpio var. koi) was conducted using a histological approach with the measurements of height of mucosa folds (HF), width of mucosa folds (WF), thickness of muscularis (TM) and cross‐sectional area (CSA). According to the change trends for these four parameters, the intestine of the koi carp was divided into anterior intestine, middle intestine and posterior intestine. The locations of the three intestine segments were defined, and their ratios along the entire intestine were accounted for 23.84 ± 1.18%, 46.77 ± 2.29% and 29.39 ± 1.65%, respectively. The anterior intestine had a significantly higher HF, compared with the middle (p < .01) or posterior intestines (p < .01). The muscularis became thin gradually from the anterior intestine to posterior part. TM was significantly different among the anterior, middle and posterior intestines (p < .01). The anterior intestine had a significantly higher CSA, compared with the middle (p < .01) and posterior intestines (p < .01), and the latter two segments had similar CSA values (p > .05). The procedure of the delimitation of the koi carp intestine segments can offer useful information for future studies on other fish species. The presented results are meaningful for studies on differential functions of the different intestine segments in fish.
