“…nauplii obtain satisfactory results when given from the first feeding, promoting larval growth and development (Jomori et al., 2008; Leitão et al, 2011; Luz et al., 2011; Takata et al, 2014). This has been observed for the Amazon ornamental fish species Nannostomus beckfordi (Abe et al., 2019), Pyrrhulina brevis (Abe et al., 2016), Heros severus (Abe et al., 2018), Astronotus ocellatus (Jomori et al., 2013) and others, such as pacu Piaractus mesopotamicus (Jomori et al., 2012; Leitão et al., 2011; Portella et al., 2014), Rhinelepis aspera (Santos et al., 2012), Lophiosilurus alexandri (Santos et al., 2016), tambaqui Colossoma macropomum , matrinxã Brycon amazonicus (Barros et al, 2019) and piau Leporinus macrocephalus (Jomori et al., 2013). However, it is necessary to evaluate the capacity of fish larvae to adapt to this kind of live food, as it is not a natural food source of freshwater fish (Jomori et al., 2012).…”
