“…According to Lojda et al (1979), this enzyme is found primarily in cell membranes where active transport takes place. Intestinal alkaline phosphatase is considered to be involved in the absorption of nutrients such as lipids, glucose, calcium and inorganic phosphate (Routaby and Portmann 1988;Dupuis et al 1991). According to these, it could undoubtedly be concluded that the intestinal digestion and transportation of nutrients occur mainly in the anterior intestinal segments in WE, but in RE, all intestinal segments are the place of very intensive intestinal absorption of nutrients.…”

Diet-related differences between the ratio of intestine length to body size and the enzymatic activity in the intestinal tract of wild and reared European eel (Anguilla anguilla L.) were studied. Compared with reared eel, wild eel showed significantly shorter relative intestine length. For the purpose of histochemical examination, different parts (anterior, middle and posterior) of intestine proper were used. Activities of non-specific esterase, alkaline and acid phosphatase, and aminopeptidase were examined in each segment. All enzymes were present in the intestines of both wild and reared European eel. Fish from both groups showed similar enzyme distribution within the enterocytes, but distribution and intensity of enzyme activity along the intestine vary depending on the group. Generally, reared European eel showed highest enzymatic activity and wider distribution of enzymes throughout all parts of the intestine. These results suggest that different diets could be one of the reasons for observed changes.

“…Positive correlation between lipase activity and lipid digestibility in mahseer (Tor khudree) (Bazaz & Keshavanath 1993), rohu (L. rohita) (Gangadhar et al 1997) and the European sea bass (Dicentrarchus labrax) (Peres & Olı´va-Teles 1999b) has been reported. AKP is considered to be involved in absorption of nutrients such as lipid, glucose, calcium and inorganic phosphate (Dupuis et al 1991;Mahmood et al 1994) and its activity has been related to food intake (Fraisse et al 1981). Ribeiro et al (1999) has found a trend for higher AKP activity in Senegalese sole that were seen to feed more actively.…”

Two, 8‐week feeding trials were conducted to compare protein‐sparing capability of dietary lipid in herbivorous grass carp (Ctenopharyngodon idella) and omnivorous tilapia (Oreochomis niloticus × O. aureus). Utilizing a 2 × 3 factorial design, experimental diets containing two levels of crude protein (380 and 250 g kg−1) and three levels of lipid (0, 40 and 100 g kg−1) were formulated for use in both feeding trials. Growth performances showed better response of both fish fed 380 g kg−1 protein diet than those fed 250 g kg−1 protein diet. Despite the dietary protein level, weight gain (WG), specific growth ratio (SGR), feed conversion ratio (FCR) and protein efficiency ratio were much higher (P < 0.05) for grass carp fed 40 g kg−1 lipid diet than those fed 100 g kg−1 lipid diet; however, there were no significant differences in tilapia fed the two diets. The feed intake of grass carp fed lipid‐free diet was the lowest, but it tended to decrease with increase in dietary lipids in tilapia. Lipid retention (LR) was negatively correlated with dietary lipid concentration of both fish. Viscerosomatic index (VSI), hepatosomatic index (HSI), intraperitoneal fat ratio (IPF) and whole‐body and liver lipid content positively correlated with dietary lipid concentration of both fish. Plasma parameters and liver enzymes activities were also positively correlated with dietary lipid concentration of both fish. Liver lipid contents were higher and enzymes activities were lower in grass carp when compared with tilapia. These data suggested that there was no evidence of a protein‐sparing effect of dietary lipids in grass carp. Tilapia has relatively higher capacity to endure high dietary lipid level compared to grass carp.

“…Similar localization was observed in enterocytes of grass carp (Stroband et al., 1979). Intestinal alkaline phosphatase is considered to be involved in the absorption of nutrients such as lipids, glucose, calcium and inorganic phosphate (Routaby and Portmann, 1988; Dupuis et al., 1991). Detection of enzymes in the supranuclear region of an enterocyte of the anterior and middle intestinal segment is indicative of its production, which has been detected by the Golgi apparatus located in that cellular region (Noaillac‐Depeyre and Gas, 1973; Stroband et al., 1979; Alpers et al., 1995.)…”

Histochemical localization of non-specific esterase, alkaline and acid phosphatase in the intestine of free-living goldline (Sarpa salpa L. 1758) was investigated. Fish were caught in the vicinity of the town of Zadar (Adriatic Sea, Croatia), and samples of three parts of the intestine proper (anterior, middle and posterior) as well as the rectum were used for presentation of non-specific esterases, alkaline phosphatase and acid phosphatase. Non-specific esterase activity was found in the cytoplasm and brush border of enterocytes in all investigated intestinal segments and the rectum. The activity was stronger in the middle and posterior part of the intestine but weaker in the anterior segment of the intestine as well as in the rectum. Intestinal alkaline phosphatase was detected in the brush border and supranuclear cytoplasm of enterocytes of all investigated intestinal segments. Enzymatic activity gradually decreased in a posterior direction. Acid phosphatase activity was observed as a fine granular reaction product in the supranuclear region of enterocytes and was almost equal in all investigated intestinal segments as well as in the rectum. The possible role of enzymes in intracellular digestion and transport is discussed.
