“…Glycerol has been proved to be a good alternative feed that can be used as source of energy for omnivorous fish (Li et al, 2010;Neu et al, 2013;Balen et al, 2014;Costa et al, 2015Costa et al, , 2017Moesch et al, 2016), in the meantime, the use of glycerol in the fattening stage of fish, as Nile tilapia, has not been sufficiently studied yet.…”

The objective of this work was to evaluate the use of crude glycerol as an energy source to replace corn, in diets for Nile tilapia (Oreochromis niloticus) in the fattening stage. Two hundred Nile tilapia (190±4.5 g) were distributed in 20 tanks, in a completely randomized design. The treatments consisted of crude glycerol at 0, 60, 120, 180, and 240 g kg-1, to replace the dietary levels of corn, in order to maintain a constant digestible energy. Fish productive performance and the chemical composition of the fillet were evaluated. Histological analyses of the hepatopancreas, intestine, and visceral fat were also carried out. Crude glycerol had no effect on the performance parameters; however, it caused a quadratic reduction of visceral fat. There was an increase in the moisture and a decrease in the ether extract of the fillet. A linear effect on the blood glucose levels was verified in fish fed the diet without glycerol, and the peak occurred at 90 min. There were no differences for measurements of intestinal villi height and hepatocyte area. Crude glycerol can replace corn in diets for Nile tilapia in the fattening stage, without adversely affecting fish metabolism, productive performance, or survival.

“…The use of glycerol as an energy source in fish varies according to fish species and size (Neu et al, 2013), possibly due to the gastrointestinal tract formation and the composition of the product (Fernandes et al, 2016). It is a potential source of energy for Nile tilapia (Meurer et al, 2012; Neu et al, 2012b; Costa et al, 2015; Gonçalves et al, 2015; Meurer et al, 2016; Moesch et al, 2016; Santos et al, 2019), common carp (Fernandes et al, 2016), channel catfish (Li et al, 2010), jundiá, pacu (Balen et al, 2014) and curimbatá (Balen et al, 2017) (Table 3).…”

“…Crude glycerol displays adequate potential to be used in the substitution of other energetic ingredients in dietary fish formulation, due to a digestible energy of 13.09 MJ kg −1 for Nile tilapia juveniles (120 g) (Meurer et al, 2012), similar to maize (13.87 MJ kg −1 ) and wheat bran (13.08 MJ kg −1 ), and higher than maize starch (10.52 MJ kg −1 ), sorghum (11.62 MJ kg −1 ) and maize germ (9.00 MJ kg −1 ), also for Nile tilapia juveniles (100g) (Pezzato et al, 2002). For Piaractus mesopotamicus , crude glycerol comprises 15.20 MJ kg −1 of digestible energy (Balen et al, 2014), higher than maize (14.49 MJ kg −1 ), wheat bran (13, 86 MJ kg −1 ) and sorghum (14.52 MJ kg −1 ) and lower than rice bran (17.61 MJ kg −1 ) (Abimorad & Carneiro, 2004). For juvenile Rhamdia quelen , crude glycerol contains 13.95 MJ kg −1 of digestible energy (Balen et al, 2014), higher than the values reported by Oliveira Filho and Fracalossi (2006), of 9.62 MJ Kg −1 for maize and 10.28 MJ Kg −1 for rice chirera.…”

Crude glycerol and its purified and synthesized forms derived from biodiesel production are non‐toxic, biodegradable, biocompatible and versatile, and can be converted into various chemicals or products for biological use. Among the possible uses, there is its use in fish feeding, due to the chemical and nutritional composition, for being classified as energetic food and has low cost. The possibility of using glycerol in fish diets has been motivated by increasing maize prices, the excessive amount of glycerol produced and its processing costs for other purposes. Glycerol use in fish diet formulations is feasible, provided that certain factors be evaluated, such as digestibility and inclusion levels. In this context, this review discussed the main aspects that must be taken into account regarding glycerol use in fish diets, such as the characteristics and chemical composition of its categories, their fish metabolism pathways and their influence on fish plasma glucose. Crude glycerol or glycerine displays good potential for use in fish feed, as it contains adequate energy concentrations and can replace part of fish feed maize. However, it is evident that assessments concerning specific physiological phases, such as fish in reproductive phases, as well glycerol stability in water, are required.

“…Crude glycerol derived from biodiesel presents great potential as a jundi a energy source, presenting an apparent digestibility coefficient of 0.89 and digestible energy content of 13.95 MJ kg À1 (Balen et al 2014). This may be related to the ease with which this nutrient is digested, absorbed and used.…”

The jundiá or silver catfish (Rhamdia quelen Quoy & Gaimard, 1824) is species native to the Americas, omnivorous, with a tendency towards carnivorous feeding habits. The species presents commercial potential, and therefore, knowledge on its nutritional requirements, as well as basic feed ingredients, is essential. Its tendency towards carnivorous feeding habits leads to some concerns regarding plant ingredient digestion abilities, although rice, soybean, flax, sorghum, ground corn or oat bran can be used as feed ingredients for this species, since they present good digestibility coefficients. In order to guarantee adequate performance of metabolic, immunological and reproductive functions, jundiá feed can be supplemented with micronutrients that minimize the effects of antinutritional factors present in plant ingredients. Plant ingredients present several economic advantages such as suitable quality, competitive prices and the fact that they are widely available in South Brazil.
