Early and late effects of feed restriction on survival, growth and hepatopancreas structure in juveniles of the red claw crayfish Cherax quadricarinatus

Impact of sodium lactate as a growth promoter on the hepatopancreas of the freshwater prawn Macrobrachium rosenbergii (de Man, 1879)

“…This is in agreement with Archanachai (2005) on Marcobracium lanchesten, Bray et al (2006) and Li et al (2008) on L. vannamei andCalvo et al (2011) on Cherax quadricarinatus. The hepatopancreas serves to secrete digestive enzymes and to store reserve food material in the form of oil globules and thus subserve the functions of the liver and pancreas in chordates (Agrawal, 1963).…”

“…The E-cells are dominated in distal tubule tips of the hepatopancreas, while R-cells, F-cells and B-cells are found frequently in its intermediate and proximal regions. This is in agreement with similar studies on other decapod crustaceans (Storch et al, 1984;Vogt et al, 1985;Aly, 2000;Sayed, 2002;Bray et al, 2006;Li et al, 2008;Leser et al, 2008 andCalvo et al, 2011). A more or less similar results were given by Aly (2000); Sayed (2002) who worked on the crayfish (Procambarus clarkii).…”

“…Several conflicting reports are found in the literature. Vogt et al (1994); Archanachai (2005); Bray et al (2006);Calvo et al (2011) reported that the hepatopancreas of different decapods divided into three parts (proximal, middle, and distal). This subdivision depends on the shape of hepatopancreatic gland.…”

Effect of dietary cornstarch levels on growth performance, enzyme activity and hepatopancreas histology of juvenile red swamp crayfish, Procambarus clarkii (Girard)

“…And it is composed of numerous blindend tubules, with each tubule consisting of different epithelial cell types, i.e. E-cell (embryonic), R-cell (resorptive), F-cell (fibrillar), and B-cell (blisterlike) Nott, 1987, 1989;Caceci et al, 1988;Calvo et al, 2011;Franceschini-Vicentini et al, 2009). Histological analysis of the hepatopancreas has been used as a practical means for assessing the nutritional condition in the shrimp culture (Gimenez et al, 2004;Reddy et al, 1999).…”

“…In crustaceans, the digestive gland or hepatopancreas is used for monitoring culture health and served as a sensitive indicator for metabolism, ecdysis phase, nutritional status, and diseases in various shrimp species (Bautista et al, 1994;Rosas et al, 1995;Van Weel, 1974;Vogt et al, 1985) because it is the site of digestion, nutrient absorption, reserve storage, synthesis and secretion of digestive enzymes (Calvo et al, 2011;Johnston et al, 1998;Sousa and Petriella, 2000). And it is composed of numerous blindend tubules, with each tubule consisting of different epithelial cell types, i.e.…”
