“…Similar results have also been observed in rainbow trout (Oncorhynchus mykiss) (Bureau et al 1999) and hybrid tilapia (O. niloticus × Oreochromis aureus) (Zhou and Yue 2012). The protein quality of the dietary ingredients is usually the leading factor affecting fish performance and protein digestibility and is the first measure of its availability for fish (Yu et al 2013). The ADC of protein in this study revealed that the protein of HM, MM, SM-A, and PM-A must be highly digestible by olive flounder.…”

“…In the present study, lipid digestibilities were considered to be high (>90 %), except for PM-B (83 %). Previous studies reported ADC values of lipid in different fish meals including Peruvian fish meal (94 %) for juvenile snakehead, O. argus (Yu et al 2013); white fish meal (78 %); and brown fish meal (76 %) for loach, Misgurnus anguillicaudatus (Chu et al 2015). The digestibility of lipids is known to be influenced by a number of factors, including degree of unsaturation, dietary lipid level, and various other constituents (Yuan et al 2010).…”

“…Fish meal in animal diets increases feed consumption, feed efficiency, and growth through better feed palatability and also improves nutrient uptake, digestion, and absorption among other ingredients (Yisa et al 2013). Some studies have investigated apparent digestibility coefficients of various fish meals in several fish species such as grower rockfish, Sebastes schlegeli (Lee 2002); juvenile snakehead, Ophiocephalus argus (Yu et al 2013); juvenile cobia, Rachycentron canadum (Zhou et al 2004); Nile tilapia, Oreochromis niloticus (Köprücü and Özdemir 2005); Atlantic cod, Gadus morhua (Tibbetts et al 2006); and juvenile haddock, Melanogrammus aeglefinus L. (Tibbetts et al 2004). The raw materials of fish meal are processed by heating, pressing, separation, evaporation, and drying.…”

Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, energy, essential amino acids, and fatty acids in extruded pellets containing various fish meals were determined for olive flounder (Paralichthys olivaceus). Eight extruded pellet diets were prepared to contain different fish meals (herring fish meal, anchovy fish meal, mackerel fish meal, sardine fish meal-A, sardine fish meal-B, tuna fish meal, pollock fish meal-A, and pollock fish meal-B) designated as HM, AM, MM, SM-A, SM-B, TM, PM-A, and PM-B, respectively. Chromic oxide (Cr 2 O 3 ) was used as an inert indicator at a concentration of 0.5 % in the diet. Feces were collected from triplicate groups of fish (151 ± 4.0 g) using a fecal collection column attached to the fish rearing tank for 4 weeks. Dry matter ADCs of the MM, SM-A, SM-B, and PM-A diets were higher than those of all the other dietary groups, and the lowest digestibility of dry matter was observed in the PM-B diet. Fish fed the MM, SM-A, and PM-A diets showed significantly higher ADC of protein than those fed the AM, SM-B, TM, and PM-B diets. Lipid ADC of PM-B was significantly lower than that of the other diets. Energy ADCs of fish fed the MM, SM-A, and PM-A diets were significantly higher than those of the other diets. The availability of essential amino acids in the MM, SM-A, and PM-A diets were generally higher than that of the other fish meal diets, while TM showed the lowest values among all the experimental diets. ADCs of fatty acids in the AM, MM, SM-A, and PM-A diets were generally higher than those of fatty acids in the other diets, and the lowest values were recorded for the PM-B diet. These results provide information on the bioavailability of nutrients and energy in various fish meals which can be used to properly formulate practical extruded feeds for olive flounder.

“…aurata was investigated at that FM replacement level (50%) that was considered the breaking point in terms of successful replacement. The similarities in trypsin and chymotrypsin activities between PBM‐ and FM‐fed fish indicate the relatively high digestibility of a high‐quality PBM protein, comparable to that of FM, as it has been shown in many fish species (Hernández et al., ; Yu et al., ) and in S . aurata (Alexis, ; Davies et al., ; Nengas et al., ).…”

“…In general, PBM contains 450–650 g/kg protein and is rich in most essential amino acids, except lysine and methionine (González‐Rodríguez et al., ; Zhou, Zhao, Li, Wang, & Wang, ). In addition, its protein digestibility, although known to be variable and affected by the raw material (Nengas, Alexis, & Davies, ), has proven to be very high in various carnivorous fish species (Hernández et al., ; Yu et al., ), including gilthead seabream ( Sparus aurata , Lupatsch, Kissil, Sklan, & Pfeffer, ; Davies, Gouveia, Laporte, Woodgate, & Nates, ).…”

In order for aquaculture to satisfy the increasing demand for farmed fish, it is essential that the sector continues searching for suitable alternatives to fishmeal (FM) that are both cost-effective and widely available. Over the last decades, plant proteins have been used successfully to reduce the inclusion levels of FM in the diets of most farmed fish species, but the high inclusion levels reduce feed intake, fish growth and nutrient bioavailability in fish body, having also negative impacts on the aquatic environment (Bell & Waagbø, 2008;Hardy, 2010). Further, the prices of many plant proteins have increased dramatically over the last decades because of the increasing demand for their use in feeds, human foods and ethanol production (Hardy, 2010). Of most importance, however, is the fact that as the aquafeed sector is expanding to satisfy the increasing demand of intensive aquaculture for aquafeeds, greater amounts of FM are required; thus, the exploration for suitable and cost-effective protein alternatives is ongoing. AbstractTwo feeding trials examined the replacement of fishmeal (FM) with poultry byproduct meal (PBM) in the diet of juvenile Sparus aurata. In Feeding trial I (100 days), three diets were formulated, where FM protein was replaced by 50% (PBM50) and 100% (PBM100) PBM, while in Feeding trial II (110 days), four diets were formulated using the same FM control diet, but FM was replaced at lower levels: 25% (PBM25), and 25% (PBM25 + ) and 50% (PBM50 + ) with the supplementation of lysine and methionine amino acids. PBM protein can successfully replace 50% of FM protein in the diet of S. aurata without adverse effects on survival, feed intake, growth performance and feed utilization, given that the diet is balanced with lysine and methionine.The proximate composition of body and muscle was unaffected by the diet, but the total FM replacement resulted in reduced lipid and energy contents in fish. A fifty per cent FM replacement by PBM did not affect haematological parameters indicating a good fish health. Similarities in trypsin and chymotrypsin activities with FM-fed fish suggest a high digestibility of PBM. High dietary levels of PBM reduced the liver gene expression of GH/IGF axis and of cathepsin D suppressing fish growth and modulating the protein turnover.

In this study, nutrients digestibility and growth performance of Nile tilapia (Oreochromis niloticus) fed on oilseed meals with crude papain enzyme were determined. A control diet (D1) of 30% crude protein (CP) was formulated using fishmeal (FM), soybean meal (SBM), canola meal (CM) and sunflower meal (SFM). The test diets were formulated with replacing 10% CP of FM by SBM (D2), CM (D3) and SFM (D4), respectively.Crude papain enzyme in powder form was incorporated at 0.06%. Digestibility trial was performed using chromium oxide as an inert marker. A feeding trial of 101 days was conducted using a 4 × 2 factorial design with 4 diets (D1, D2, D3 and D4) and 2 papain enzyme inclusion levels at 0.06% and 0% using 720 Nile tilapia fingerlings (7 ± 3 g). The fingerlings were randomly distributed into 8 groups of 3 replicates of 30 fingerlings per net hapa (2 × 1 × 1 m 3 ). Fish were fed twice daily at 5% of their biomass at 10 AM and 4 PM in two equal meals. Apparent digestibility coefficients increased (p < 0.05) on crude papain enzyme supplementation. There was increase in final body weight (47.32 ± 2.10 g) on 0.06% enzyme than without enzyme (0%) (46.17 ± 2.14 g) (p > 0.05). Irrespective of enzyme supplementation, fish fed FM-based diet were larger (56.89 ± 1.37 g) (p < 0.05) than those fed on oilseed meals; SBM (45.59 ± 0.91 g), CM (43.89 ± 2.12 g) and SFM (40.59 ± 1.60 g). Based on the study, 0.06% crude papain enzyme inclusion increased nutrients digestibility and growth performance of Nile tilapia. Therefore, crude papain enzyme is recommended as a feed additive in Nile tilapia diets to promote growth. However, more research is recommended to determine optimum inclusion levels of crude papain enzyme in Nile tilapia diets.
