“…These residues are conserved in the present sequences except for B13 where a conservative substitution (aspartate for glutamate) was observed in the arawana, goldeye, butterfly fish and white sucker. Generally, carbohydrates are low in teleost diets, and it was reported that teleosts do not use glucose efficiently as a general source of energy (Wilson, 1994). Parrizas et al (1994) reported the presence of functional insulin recep-tors in tilapia skeletal muscle, which supports the earlier reports (King and Kahn, 1981;Mommsen and Plisetskya, 1991) on the important role of insulin in promoting somatic growth in teleosts.…”

Several preproinsulin cDNAs were isolated and characterized from four members of the Osteoglossomorpha (an ancient teleost group); Osteoglossum bicirrhosum (arawana), Pantodon buchholzi (butterfly fish), Notopterus chitala (feather fin knife fish), Hiodon alosoides (goldeye) and Gnathonemus petersii (elephantnose). In addition, we isolated and characterized the preproinsulin cDNA from Catostomus commersoni (white sucker, as a representative of a generalized teleost). The comparative analysis of the sequences revealed conservation of the cystine residues known to be involved in the formation of the disulfide bridges, as well as residues involved in the hexamer formation, except for B-17 in the butterfly fish, the arawana and the goldeye. However, the N-terminus of the B-chain was very weakly conserved among the species studied. Residues known to be significant for maintaining receptor-binding conformation and those known to comprise the receptor-binding domain were all conserved, except for a conservative substitution at B13, aspartate substituted glutamate in the arawana, goldeye, butterfly fish and white sucker, and at B16, phenylalanine substituted tyrosine in the elephantnose. Phylogenetic analysis of the sequences revealed a monophyletic grouping of the osteoglossomorphs, and showed that they were not the most basal living teleost. Comparative sequence analysis of preproinsulins among the osteoglossomorphs was useful in assessment of intergroup relationship, relating elephantnose with the feather fin knife fish and the arawana, butterfly fish, and goldeye. This arrangement of species is consistent with relationships based on other more classical parameters, except for the goldeye which was assessed as being sister to all the osteoglossomorphs. The white sucker was grouped with the common carp and both are cyprinids.

“…Fish have poor utilization of carbohydrates and persist hyperglycemia when fed on sugary sugars [39], causing fish to develop symptoms of slow growth and fatty liver, thereby inhibiting fish growth and immune function, leading to a decrease in disease resistance [40]. Studies have shown that fish were able to transport fat from stored tissues or other non-energy-consuming tissues to the energyconsuming tissues [41].…”

“…Carbohydrate use in fish is dependent upon the type of starch, degree of gelatinization, and dietary inclusion level (Singh and Nose 1967, Wilson 1994, Shiau 1997. Starch gelatinization enhances its digestibility by making it more susceptible to enzymatic hydrolysis (Bergot 1991, Podoskina et al 1997, Mohapatra et al 2003, and can thus make it a valuable energy source (Bergot and Br≈que 1983).…”

Background. Dietary carbohydrate use is a priority in aquaculture because of its low cost and high availability, especially for herbivorous and omnivorous fish. Gelatinization is a process that improves carbohydrate use. However, excess dietary carbohydrate may cause metabolic stress and cellular changes as fish inherently use low carbohydrate. The aim of this study was to determine the effects of three sources of gelatinized carbohydrate (GC) on haematology and hepatic structure of Catla catla fingerlings. Materials and methods. Six isocaloric (17.1-17.5 kJ · g -1 ) semi-purified diets were prepared from rice, corn, or tapioca, each at 40 or 50% GC. Crude protein (CP) level was fixed at 35 and 25% for the low GC (40%) and high GC (50%) levels, respectively. Ninety Catla catla fingerlings were distributed in 6 treatments, each with three replicates, for a 60-day feeding trial. At termination, blood haemoglobin, RBC, WBC, and liver histology were studied.Results. Significant differences (P < 0.01) in haemoglobin, RBC, and WBC were observed among the different carbohydrate-fed groups at 40% GC level. With increased dietary GC level, hepatocyte hypertrophy and vacuolation was intensified. Maximum hypertrophy was noticed in the fish fed tapioca at 50% GC, with extensive cytoplasmic vacuolation. No mortality was found in any group at any GC level. Conclusion.No mortality of Catla catla fingerlings was observed due to feeding of high GC levels from corn, rice, or tapioca. However, hepatocyte hypertrophy was observed. Long-term feeding beyond 60 days may cause adverse hepatic cellular changes, but needs further research.
