“…Our observation that the number of goblet cells was significantly more abundant in the proximal than in the distal intestine is in contrast with other data present in the literature [8,19]. However, a recent study suggests that the greater abundance of goblet cells within the posterior tract could be a misinterpretation due to the massive presence of pinocytotic vacuoles in the apical part of the enterocyte's cytoplasm [23]. Moreover, goblet cell density is strongly affected by several external factors comprising nutrition, physiology and immunology [24,25], and this must be considered as a possible source of variability.…”

To increase the sustainability of trout farming, the industry requires alternatives to fish-based meals that do not compromise animal health and growth performances. To develop new feeds, detailed knowledge of intestinal morphology and physiology is required. We performed histological, histochemical, immunohistochemical and morphometric analysis at typical time points of in vivo feeding trials (50, 150 and 500 g). Only minor changes occurred during growth whereas differences characterized two compartments, not linearly distributed along the intestine. The first included the pyloric caeca, the basal part of the complex folds and the villi of the distal intestine. This was characterized by a significantly smaller number of goblet cells with smaller mucus vacuoles, higher proliferation and higher apoptotic rate but a smaller extension of fully differentiated epithelial cells and by the presence of numerous pinocytotic vacuolization. The second compartment was formed by the proximal intestine and the apical part of the posterior intestine complex folds. Here we observed more abundant goblet cells with bigger vacuoles, low proliferation rate, few round apoptotic cells, a more extended area of fully differentiated cells and no pinocytotic vacuoles. Our results suggest that rainbow trout intestine is physiologically arranged to mingle digestive and absorptive functions along its length.

“…Reduced mucosal folds towards the rectum and increased number of Goblet cells are associated with the assimilation of ions and fluids, lubricates and protects the intestinal mucosa from mechanical damage, and facilitates the expulsion of feces. Goblet cells produce mucus, which protects the intestinal mucosa from mechanical and chemical damage, assists the absorption and transport of molecules through the membrane, and protects against microorganisms (Arman and Ucuncu, 2017). According to Buddington et al (1997), the intestine also regulates water and electrolyte balance and immunity.…”

In Indonesia, there are several types of freshwater fish that the community has cultivated. Besides having high nutritional value, Freshwater fish also have high economic value for trading, such as gourami. One of the obstacles in the cultivation of freshwater fish is the price of feed. This research is oriented towards alternative feeds to reduce production costs by utilizing avocado seeds and pumpkin seeds. This study aimed to determine the effect of feeding a combination of avocado seeds and pumpkin seeds on the histopathology of gourami. This study used a non-factorial completely randomized design (CRD) method with four treatments and six replications P0, P1, P2, and P3. P0 (Control feed/pellet), P1 (Feed 40 grams of avocado seeds + 40 grams of pumpkin seeds + 20 grams of mixed ingredients), P2 (Feed of 20 grams of avocado seeds + 60 grams of pumpkin seeds + 20 grams of mixed ingredients) and P3 ( Feed 60 grams of avocado seeds + 20 grams of pumpkin seeds + 20 grams of mixed ingredients). Data were analyzed using ANOVA and Advanced Test with a significant level of 5%. The results showed that the P2 treatment could increase the villi height and the number of Goblet cells in the intestines of gourami fish. It can be concluded that the combination of avocado seeds and pumpkin seeds has a significant effect on the histopathological picture of the digestive organs of gourami

“…Meanwhile, fish intestine after treatment P1 (10% FFM) was seen to produce goblet cells. These cells produce mucus, which has a role in facilitating absorption and transportation of feed molecules through membranes, as well as providing protection against micro-organisms in the intestine 31 . The test feed containing 10% FFM was seen to be absorbed by the intestine of silver pompano 9 .…”

Use of chicken feather meal fermented with Bacillus subtilis in diets to increase the digestive enzymes activity and nutrient digestibility of silver pompano Trachinotus blochii (Lacepede, 1801)

Background: Feather has the potential to be used as a fish feed ingredient because it has high protein content (80-85%), and is rich in amino acids arginine, leucine, isoleucine and valine. However, the protein consists mainly of keratin, which is classified as fiber that is difficult to digest. Therefore, to improve digestibility, the keratin protein is degraded using microbial Bacillus subtilis. This study aimed to determine the digestibility of fermented feather meal (FFM) in silver pompano (Trachinotus blochii) diets and to observe the histological structure of their intestines after digestion. Methods: The method used was a one factor experiment with five treatments and three replications each, which were: diet without FFM, diet containing 10% FFM, 20%, 30% and 40%. The diets were given to juvenile silver pompano (with average body weight of 8.56 ± 0.18 g) and stocked in 15 similar 20-L plastic jars with 10 fish per jar in a density of 100 L capacity container. The experimental diets were given three times daily at approximately 8.00 AM, 12.00 PM and 5.00 PM to apparent satiation for 60 days. Results: The results showed that the use of FFM increased the activity of digestive enzymes (protease and lipase), but reduced the amylase activity of silver pompano, which was significantly different between treatments (P <0.05). Meanwhile, the diet containing 20% FFM produced the highest feed and protein, which are 37.05% and 67.24%, respectively. This was significantly different from other treatments (P <0.05), and was effectively absorbed by fish intestines. Conclusion: The addition of chicken feather meal fermented with Bacillus subtilis could increase the activity of protease and lipase enzymes and nutrient digestibility of silver pompano but not amylase activity.
