“…Several studies suggested that regulated PepT1 expression by dietary-free amino acid, peptides and intact protein in fish could affect growth performance directly and/or indirectly (Ostaszewska et al 2009(Ostaszewska et al , 2010aBakke et al 2010;Liu et al 2013Liu et al , 2014. Fish protein hydrolysate is obtained by enzymic or formic acid hydrolysis and includes rich small peptides and amino acids (Liaset et al 2000(Liaset et al , 2002Mach & Nortvedt 2011). When Atlantic cod (Gadus morhua) fed diets contained different fractions of fish protein hydrolysate or free amino acids, it would alter the regional Pept1 expression profile in the intestine (Bakke et al 2010).…”

The intention of the study was to investigate the effect of ultrafiltered fish protein hydrolysate (UF) level on growth, feed utilization, apparent digestibility coefficients and proximal intestine peptide transporter 1 (PepT1) mRNA level for juvenile turbot (Scophthalmus maximus L.). Experimental diets (UF‐0, UF‐5, UF‐10, UF‐15 and UF‐20) were prepared containing about 68% plant protein, and fish meal protein was, respectively, replaced by 0%, 5%, 10%, 15% and 20% UF of dietary protein. Diet PP contained about 78% plant protein, and diet CAA contained about 10% crystalline amino acid mixture. All diets were fed to seven triplicate groups of turbot (initial weight 16.05 ± 0.03 g) for 68 days. Fish fed diet UF‐10 had an increasing tendency in growth compared with diets contained UF, while dietary UF level was not significantly correlated with specific growth rate and feed intake. Feed efficiency, protein efficiency ratio and protein productive value significantly correlated with dietary UF level, and fish fed diets contained low‐level UF had higher digestibility than that diets UF‐0, PP and CAA. There was a decreasing tendency in PepT1 expression level with dietary UF level. The results indicated that low‐level UF showed a positive effect on growth and feed utilization in juvenile turbot.

“…The current methods include composting as fertilizer (Liao et al 1994), production of meals for animals (Ferreira and Hultin 1994) and fish oil production (Aidos et al 2001). Moreover, by-products can be hydrolysed to obtain fish protein hydrolysates (Liaset et al 2000;Martone et al 2005) utilizable as nutrient source for aquaculture and microbial growth (Poernomo and Buckle 2002;Vazquez et al 2004). Fish wastes have great potential to be used as nutrient sources for bacterial growth, because cell Keywords Fish by-products, growth media, lipase production, Staphylococcus xylosus.…”

Aims: The objective of this study was to demonstrate that fish‐processing by‐products could be used as sole raw material to sustain the growth of Staphylococcus xylosus for lipase production. Methods and Results: Bacterial growth was tested on supernatants generated by boiling (100°C for 20 min) of tuna, sardine, cuttlefish and shrimp by‐products from fish processing industries. Among all samples tested, only supernatants generated from shrimp and cuttlefish by‐products sustained the growth of S. xylosus. Shrimp‐based medium gave the highest growth (A600 = 22) after 22 h of culture and exhibited the maximum lipase activity (28 U ml−1). This effect may be explained by better availability of nutrients, especially, in shrimp by‐products. Standard medium (SM) amendments to sardine and tuna by‐product‐based media stimulated the growth of S. xylosus and the highest A600 values were obtained with 75% SM. Lipase activity, however, remained below 4 U ml−1 for both sardine and tuna by‐product‐based media. Conclusions: Fish by‐products could be used for the production of highly valuable enzymes. Significance and Impact of the Study: The use of fish by‐products in producing S. xylosus‐growth media can reduce environmental problems associated with waste disposal and, simultaneously, lower the cost of biomass and enzyme production.

“…The substitution of fish meal with commercial hydrolyzate also increased the whole-body protein retention for Atlantic salmon (S. salar) culture (Refstie et al, 2004). Protein hydrolyzates have a large quantity of low molecular weight peptides (Liaset, Lied, & Espe, 2000), which are absorbed more efficiently when compared to intact proteins (Espe et al, 1993). The transport of di and tripeptides occurs on the apical membrane of enterocytes through peptide transporter 1 − PEPT1 (Daniel & Kottra, 2004;Smith, Clémençon, & Hediger, 2013).…”

This study evaluated the substitution of fish meal with tilapia protein hydrolyzate (TPH) in diets for Silver catfish (Rhamdia quelen) by verifying the effects on growth, body composition, blood and biochemical parameters, and biomarkers of oxidative stress. Five isoproteic and isoenergetic diets (37% crude protein, 3,800 kcal/kg) were produced with different substitution levels of TPH (0%, 5%, 10%, 15% and 20%) for fishmeal. The hydrolyzate was obtained by enzymatic hydrolysis from carcasses of Nile tilapia (Oreochromis niloticus), which were exposed to swine pepsin enzyme at 36°C for four hours. The experimental design was completely randomised with five treatments and four replications. The inclusion of 20% TPH in diets for silver catfish increased the growth of Silver catfish juveniles. At levels above 5%, there was an increase in body protein deposition and the efficiency of oxidative metabolism.
