“…The pacamã Lophiosilurus alexandri Steindachner 1876 is a Siluriformes much appreciated for its meat. The breeding and raising of its larvae can be successfully carried out under laboratory conditions (Luz & Santos, ; Guimarães‐Cruz et al , ; Santos & Luz, ; Santos et al , ; Melillo Filho et al , ; Costa et al , ). Pedreira et al (), however, stated the use of green tanks can compromise the use of live food during larval rearing of this species, but to date, the effects of how the environmental colour can influence the performance and well‐being of juveniles is unknown.…”

The growth, physiology and skin pigmentation of pacamã Lophiosilurus alexandri juveniles were evaluated in an experiment using different tank colours (white, yellow, green, blue, brown and black) over an 80 day period. The tank colours did not cause significant differences to final body mass, total length, survival rate, carcass composition (moisture, crude protein, ash, ether extract, calcium, phosphorus, energy), or to plasma protein, triglyceride and cholesterol values. Haematocrit values, however, were highest for fish kept in white tanks (ANOVA P < 0·05), while the greatest haemoglobin levels were recorded for fish kept in blue and brown tanks (P < 0·01). The concentrations of cortisol (P < 0·001) and glucose (P < 0·01) were the most in fish in the black tanks. Tank colour affected skin pigmentation significantly, with fish in white tanks having the highest values of L* (brightness) and the lowest values in blue and black tanks. L*, however, decreased in all treatments throughout the experiment. C* increased significantly over the course of the experiment in fish kept in white tanks. Similar increases of C* were recorded in the other treatments but to a lesser extent. The use of black tanks during the cultivation of L. alexandri caused stress and should be avoided. Cultivation in white and yellow tanks produced individuals with a pale skin colour, while cultivation in blue and black tanks resulted in juveniles with a darker and more pigmented skin.

“…Lophiosilurus alexandri is a Neotropical catfish species with great potential for aquaculture (Kitagawa et al, 2015; Ribeiro et al, 2019) due to its favourable production characteristics, such as ease of artificial propagation (Costa et al, 2015; Luz & Santos, 2008), acceptance of artificial diets (Salaro et al, 2015) and quality of meat without intramuscular bones (Gonçalves Junior et al, 2019; Mattioli et al, 2017). Therefore, the aim of this study was to evaluate the OEO ( Origanum vulgare ) dietary supplementation for the catfish L .…”

The use of essential oils (EO's) as feed additive has been explored as tool to improve fish growth and health. The aim of this study was to evaluate the oregano essential oil (OEO) (Origanum vulgare) dietary supplementation for the catfish Lophiosilurus alexandri. Four diets supplemented with different OEO levels (0.0, 1.0, 2.0 and 4.0 g kg−1) were evaluated in a feed trial conducted with fish of 15.7 ± 1.8 g and 9.5 ± 0.45 cm for 13 weeks. Were evaluated growth performance, biochemical parameters, intestinal histomorphometry, whole‐body composition and muscle growth. Polynomial analysis showed that weight gain, length gain and specific growth rate were improved in fish fed with OEO supplemented diets, being 2.37, 2.56 and 2.33 g kg−1 the respective levels that maximize these variables. Plasma glucose, cholesterol, triglycerides, LDL and HDL increased with OEO levels between 1.80–2.47 g kg−1. Intestinal histomorphometry was not affected by OEO. Body protein content and hyperplasic muscle fibres were maximized with 2.10 and 2.25 g kg−1 OEO, respectively. Body moisture, total lipids, ash and hypertrophic muscle fibres were not affected by OEO. In conclusion, dietary supplementation with 2.10–2.56 g kg−1 OEO improves growth performance, body protein retention and muscle growth of L. alexandri.

“…The species has been suffering from overfishing because it is preferred by fishermen, and thus is considered endangered (MMA, Brasil, 2014). It presents partial spawning, sedentary behaviour and a preference for lentic environments (Travassos, 1959), as well as parental care and release of its eggs on sandy substrates (Costa et al, 2015; Junior at al., 2019). It is commonly used in restocking programs in the Rio São Francisco basin (Navarro et al, 2017) and has already been successfully larvicultured in different cultivation systems with the use of live food (Cordeiro et al, 2016; Melillo Filho et al, 2014; Takata et al, 2014).…”

Biochemical parameters of fish are important indicators of homeostasis as they represent an organism's response to the environment. Lophiosilurus alexandri is an endemic and endangered species of the São Francisco River in Brazil with potential for aquaculture; however, blood biochemical studies of this species are scarce. The present study compared blood biochemical parameters of male and female L. alexandri, at four different ages. The following analytes were evaluated: alanine aminotransferase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), calcium, chlorine, magnesium, total proteins, albumin, urea, glucose, triglycerides and cholesterol. Male fish had higher values than females for ALT at 372 days after hatching (DAH), magnesium at 481 DAH and triglycerides at 372 and 481 DAH (p < 0.05). The other analytes did not differ significantly (p > 0.05) between males and females at any of the collection times. The results allow us to conclude that biochemical differences between males and females are less pronounced than those observed among different ages of the same sex.
