“…The results of fish feed intake were in the same pattern of body weight and weight gain. This finding coincides with that of Goda et al (2020), indicating that the enzyme increased the feed intake of fish. In this study, the control −ve (low CP) had the highest feed conversion ratio (1.67), however, the other three groups had similar non‐significant values (1.53–1.57).…”

“…Haemoglobin level was unaffected by the 200 mg/ kg dietary protease (Adeoye et al, 2016). On contrary, Goda et al (2020) reported that the haemoglobin level increased in seabass fish diets supplemented with protease enzymes in relation to the control group. Nevertheless, the two groups containing protease enzyme had higher numerical RBCs values than the two control groups.…”

“…Shi et al (2016) found no significant differences in serum triglycerides and total cholesterol levels among all groups in carp fish. However, levels of cholesterol and triglycerides were found to be increased in serum of seabass fed diets supplemented with protease in relation to the control group (Goda et al, 2020). In this study, there was no significant difference in the serum protein, albumin or globulin levels among the experimental groups.…”

This study was conducted to evaluate the effect of using protease in diets of Nile tilapia on growth performance, water quality, blood parameters and intestinal morphology. The cost of these diets and their return on fish performance was calculated. A total of 360 fish were randomly allocated into four groups with triplicates (30 fish per replicate). Four diets were formulated; two controls (without protease supplementation) and two experimental diets (supplemented with protease). The first control diet contained the normal protein requirement (30% CP; control +ve), while the second control had a low protein content (29% CP; control −ve). The third diet was supplemented with protease at a dose of 500 g/ton, and its CP content was reduced to 29.0%, by reducing the fish meal content. The fourth diet contained the same CP level as the first control (30%) and supplemented with 250 g protease per ton feed. The experiment lasted for 14 weeks. The results showed that body weight and length, weight gain, specific growth rate, feed intake and feed conversion efficiency in the control −ve group (low CP) supplemented with protease were similar (p > 0.05) to that of the control +ve with normal CP content. However, these performance parameters were lower (p < 0.05) in fish fed low CP diet without protease supplementation. Providing protease to the control +ve diet improved all measured performance indices. The ammonia and nitrite concentrations of the water were reduced (p < 0.05) in control −ve and protease‐supplemented groups. The height and width of intestinal villi were increased (p < 0.05) in fish fed diets containing protease. The inclusion of protease reduced the diet cost and also the feed cost of fish weight gain. In conclusion, supplementation of protease can improve the productive performance of fish, spare dietary protein and produce economical diets. Moreover, it can help in improving the water quality of fish via lowering the ammonia and nitrite contents, or through increasing the degradation of dietary protein.

“…ALAT and ASAT have an important role in amino acid synthesis in higher vertebrates including fish due to their roles in deamination and transamination. Goda, Srour, et al, 2019 andGoda et al, 2019b provided such metabolic data indicative of the health of seabass fed High Protein Distillers Grains (HP-DDG) under experimental conditions with similar findings to this study with but some improvement of blood indices. Excess deposition of energy as glycogen or lipid can enhance the activities of several key enzymes involved in glycolysis, lipogenesis as well as protein and amino acid synthesis and degradation.…”

Six experimental isonitrogenous (380 g kg -1 crude protein) and isolipidic (80 g kg -1 ) diets were formulated for juvenile carp Cyprinus carpio. The fish meal protein component of a basal diet (control treatment) was effectively replaced by yeast protein concentrate unrefined (YPC U ), yeast protein concentrate refined (YPC R ), yeast protein concentrate potable alcohol (YPCPA) at 300 g kg -1 of total dietary protein originating from a novel wheat fermentation process. Distillers dried grains with solubles (DDGS) at two levels (150 and 300 g kg -1 ) of dietary protein were also tested separately. After an 8-week feeding trial, carp fed YPCU30 recorded the highest (p ≤ .05) growth performance and feed efficiency. The apparent net protein utilization of phosphorus, sodium, magnesium and chromium for all diets tested showed significant differences of retention efficiencies. The control fed carp had (p < .05) significantly lower phosphorus and magnesium efficiency than the carp fed other diets. Histological examinations showed the density of microvilli in the region of fish fed YPCU30, YPCPA30, DDGS15 and DDGS30 was decreased compared with the control fed fish with no significant differences were found among the treatments (p ≥ .05). Significant differences in the number of hepatocytes were observed between fish fed YPCR30 or YPCPA30 and DDGS30. Furthermore, no significant (p ≥ .05) differences were obtained in the number of hepatocytes in the fish fed YPCU30 and DDGS15 diets with fish fed the control diet. Hepatic structure showed that the liver of the fish fed the control, YPCU and YPCR diets appeared to be healthy with no signs of pathological change. In conclusion, fermented wheat-derived yeast protein concentrate and distillers dried grains with solubles are promising ingredients in carp diets to reduce feed costs and achieve aquaculture sustainability.

Fish meal (FM) has typically been the main source of dietary protein in the commercial production of fish as reported over the years (Edwards et al., 2004). This is due to its high protein content, excellent amino acid profile, as well as its high nutrient digestibility (Gatlin et al., 2007). However, being too reliant on any one available ingredient imposes increased risks associated with supply, price and quality fluctuations as reported by Glencross et al. (2007). In fact, aquafeed production costs are very high (over 50%) in some aquaculture practices. In order to decrease dietary costs, increase profitability and obtain good growth, expensive ingredients may be substituted with lower-cost ingredients How to...

“…Therefore, the greatest challenge for the aquaculture industry is to find ecofriendly and risk-free protein concentrates for utilization in formulated fish feeds (Bowyer et al, 2020;El-Husseiny et al, 2017, 2018El-Nokrashy et al, 2021;Glencross et al, 2019;Hassaan, Mohammady, et al, 2021;Kok et al, 2020). Recently, protein ingredients of terrestrial animal origin, such as insect meals, have been advocated as viable protein sources, which could potentially replace FM and plant sources such as soybean meal in aquafeeds either partially or totally Goda et al, 2020;Hassaan et al, 2018;Hassaan, Mahmoud, et al, ). The feasibility of insect meal an alternative to terrestrial plant and animal protein sources in aquaculture and animal feeds have been reported by a number of authors recently (Fisher et al, 2020;Smetana & Mathys, 2019).…”

A 12-week feeding trial with Asian sea bass Lates calcarifer juveniles was conducted to evaluate the response of feeding defatted Superworm (Zophobas morio) larval meal on growth performance, feed utilization, apparent digestibility coefficient of nutrients and haemato-biochemical status for Asian sea bass. Five isonitrogenous (450 g/kg) and isolipidic (125 g/kg) experimental diets were formulated. A basal diet that contained no insect meal from defatted Superworm (DFSM) served as the control. Four diets were formulated where DFSM was included at 30 g/kg; 11.11% (DFSM-3), 60 g/ kg; 22.22% (DFSM-6), 90 g/kg; 33.33% (DFSM-9) and 120 g/kg; 44.44% (DFSM-12), respectively, on a dry matter basis. All essential amino acids (EAA) except methionine, phenylalanine and threonine in DFSM compared favourably with fishmeal (FM) and arginine, histidine, isoleucine, leucine, tryptophan and valine were higher than that of FM. No significant (p > .05) differences in weight gain, specific growth rate and feed conversion ratio, hepato-somatic and viscera-somatic index were apparent among fish fed different levels of DFSM. Furthermore, no significant (p < .05) differences were found for apparent digestibility of dry matter (DM) and crude fat in response to dietary DFSM with different levels. A significant decreased linear relationship in the ADC of protein (p = .042) was noted as the level of DFSM incorporation increased in the experimental diet. No significant differences in haematocrit, MCHC and creatinine values were found among the experimental diets. However, a significant quadratic increase in haematocrit (p = .039) was detected as the level of DFSM increased in the diet. Serum cholesterol, alkaline phosphatase (ALP), glutamic pyruvic transaminase (GPT) and glutamic oxaloacetate transaminase (GOT) were linearly reduced with the increasing of dietary DFSM (linear, p = .043; p = .023; p = .018; p = .028). The findings of the present study indicated that growth, feed efficiency and haemato-biochemical indices were not adversely affected by partial substitution of FM up to 120 g/kg dietary inclusion of Superworm meal. We discuss this in the context of aquafeed applications for marine fish production in Asia for more sustainable production using novel protein ingredients and wider implications.
