“…However, the literature on the effects of NSP enzymes on the nutrient digestibility and performance of fish is not always consistent. The results of this study are consistent with those of studies on African catfish Clarias gariepinus (Yasemin & Turan, 2010), great sturgeon Huso huso fingerlings (Ghomi, Shahriari, Langroudi, Nikoo, & von Elert, 2012), and tilapia Oreochromis niloticus (Adeoye, Jaramillo-Torres, Fox, Merrifield, & Davies, 2016;Maas, Verdegem, Dersjant-Li, & Schrama, 2018). However, other researchers have reported different results on rainbow trout Oncorhynchus mykiss (Drew, Racz, Gauthier, & Thiessen, 2005;Ogunkoya, Page, Adewolu, & Bureau, 2006) and tilapia O. niloticus L. (Yigit & Olmez, 2011).…”

The purpose of this study was to evaluate the effects of nonstarch polysaccharide (NSP) hydrolase (primarily xylanase and β‐glucanase), present in plant protein‐based diets, on growth, nutrient digestibility, and protease/amylase activity of Yellow River carp, Cyprinus carpio var.. Six hundred fish were randomly allocated to four groups in five replicates and fed diets with different NSP enzyme levels (0, 0.025, 0.05, and 0.1%) for 56 days. The addition of 0.05 and 0.1% NSP enzymes to diets significantly improved the specific growth and protein efficiency rates and reduced the feed intake and feed conversion rates (p < .05). The apparent digestibility of dry matter, crude protein, energy, crude fiber, crude ash, and some amino acids was also significantly improved with 0.05 and 0.1% NSP enzymes (p < .05). The protease activity of hepatopancreas in fish fed the diet with 0.1% NSP enzymes was significantly higher than that of the control diet (p < .05). For four sample‐collecting time points, except for 5 hr after feeding, the protease activity in the middle‐rear intestine of the 0.025% enzyme group was significantly higher than that of the control group (p < .05). Addition of 0.025 or 0.05% NSP enzymes did not affect hepatopancreas amylase activity but increased the amylase activity of the front and middle‐rear intestines to a certain extent. However, a high dose of NSP enzymes (0.1%) inhibited hepatopancreas amylase activity. Determination of the effects of NSP enzymes on growth, nutrient digestibility, and endogenous enzyme activity indicated that the addition of 0.05% NSP enzymes in diets is optimal for Yellow River carp.

“…The inclusion of exogenous protease and lipase in the feed for pirarucu juveniles showed significant and positive differences in relation to the control treatment (p < 0.05) ( Table 2). Recent and similar results were also achieved by Yildrim & Turan (2010), Zamini et al (2014) and Adeoye et al (2016), being this latter work important in determining the importance of phytase for the mitigation of antinutritional factors related to phytate, an agent capable of reducing the bioavailability of proteins, amino acids and minerals from the ingredients present in the diet.…”

The objective of this work was to verify the effect of exogenous digestive enzymes protease, lipase and amylase on the feeding of pirarucu. In a completely randomized design, we tested three levels of inclusion for both exogenous enzymes against a control commercial feed lacking any enzymatic enrichment. Inclusion levels were as follows: (Control) = no enzymes; (T1) = 0.1% Amylase; (T2) = 0.2% Amylase; (T3) = 0.4% Amylase; (T4) = Protease 0.1%; (T5) = Protease 0.2%; (T6) = Protease 0.4%; (T7) = Lipase 0.1%; (T8) = Lipase 0.2%; (T9) = Lipase 0.4%. After the end of the experiment it was possible to find a significant difference (p < 0.05) in relation to the Control treatment only in the zootechnical data of the treatments that added protease and lipase to the pirarucu feed (T4, T5, T6, T7, T8, T9). The use of exogenous digestive enzyme protease and lipase are indicating on the pirarucu feeding, as it positively influences its growth.

“…Several studies have shown that the addition of β-xylanases and β-glucanases to fish feed can improve fish growth rate and feed utilization, enhancing the quality of fish. These observations were reported for Atlantic salmon ( S. salar ) (Jacobsen et al 2018 ), silver perch ( Bidyanus bidyanus ) (Stone 2003 ), tilapia ( O. niloticus × O. aureus ) (Lin et al 2007 ; Maas et al 2018 , 2020 ), African catfish ( C. gariepinus ) (Yildirim and Turan 2010 ), and shrimp ( Litopenaeus vannamei ) (Qiu and Davis 2017 ).…”

“…Similarly, Atlantic salmon, Salmo salar L. (a carnivorous fish) showed an enhanced feed utilization rate after receiving exogenous α-amylase through feed, and flesh quality was more appreciated by fish consumers (Carter et al 1992 , 1994 ). Yildirim and Turan ( 2010 ) added a commercial preparation containing β-amylase to the feed of African catfish ( Clarias gariepinus ). The use of this enzyme, along with protease, fungal xylanase, β-glucanase, endo-β-glucanase, pentosonase, α-amylase, and pectinase, improved fish growth and the specific growth rate (SGR).…”

Modern aquaculture must be sustainable in terms of energy consumption, raw materials used, and environmental impact, so alternatives are needed to replace fish feed with other raw materials. Enzyme use in the agri-food industry is based on their efficiency, safety, and protection of the environment, which aligns with the requirements of a resource-saving production system. Enzyme supplementation in fish feed can improve digestibility and absorption of both plant- and animal-derived ingredients, increasing the growth parameters of aquacultural animals. Herein we summarized the recent literature that reported the use of digestive enzymes (amylases, lipases, proteases, cellulases, and hemicellulases) and non-digestive enzymes (phytases, glucose oxidase, and lysozyme) in fish feed. In addition, we analyzed how critical steps of the pelleting process, including microencapsulation and immobilization, can interfere with enzyme activity in the final fish feed product.
