Abstract: The survival and the growth of Pseudoplatystoma corruscans larvae exposed to four photoperiods: light:dark (LD) 0:24, LD 10:14, LD 14:10, and LD 24:0, in a brackish water (5‰) culture were analyzed. Larvae were fed with Artemia sp. nauplii at a 500 nauplii/larvae/day ratio.

“…Larvae of treatments 0L:24D and 6L:18D showed less movement in the tank, which probably reduced the encounter with larvae sisters and consequently cannibalism, and conversely increased survival. This same condition was observed for golden catfish larvae (SCHÜTZ & NUÑER, 2007;CAMPAGNOLO & NUÑER, 2008). For some species of catfish with nocturnal habits, an increased photoperiod entails high drive, with energy expenditure and consequent reduction in survival (APPELBAUM & KAMLER, 2000;ALMAZÁN-RUEDA et al, 2005).…”

“…According to CAMPAGNOLO & NUÑER (2008), rearing catfish larvae (Pseudoplatystoma corruscans) in a long photoperiod resulted in lower survival rates due to the intense activity of swimming larvae with higher energy consumption in these environments. Agreeing to these results, continuous dark would be better because a fish has difficulty to capture the other, reducing cannibalism with a consequent increase in survival.…”

“…Mean±standard deviation of survival, uniformity, growth, and body composition parameters of Hoplias intermedius juveniles maintained in photoperiod treatments during 90 days (1) . fish showed the best survival rates (Campagnolo & Nuñer, 2008). Therefore, differences for survival of different species can be attributed to variations in the photoperiod requirement, which is species specific and depends on the development stage of the animal.…”

“…Dark conditions provided the chance of cannibalism and agonistic interactions (Schütz et al, 2008). Nevertheless, in Pseudoplatystoma corruscans larvae, the cannibalism was lower with decreasing photoperiod (Campagnolo & Nuñer, 2008), showing that there are different responses to photoperiod for each species of fish.…”

“…Nonetheless, reduced growth observed at 1200 lx indicates that too much brightness of the rearing system influences the behavioural changes in both larvae and prey resulting in higher encounter rates (Downing & Litvak, 1999). Also, the synergic effect between light and food availability favours larval growth, most likely due to the release of growth hormones (somatotropin), as reported in Pseudoplatystoma corruscans (Campagnolo & Nuñer, 2008). Moreover, some authors reported that environmental stress at elevated light intensities results in low feeding rates (Downing & Litvak, 1999).…”
