“…In agreement with empirical findings in several catfish species (Clarias gariepinus, Bruton 1979; Silurus glanis, Anthouard et al 1987;Hoplosternum littorale, Boujard et al 1990) as well as with previous studies on H. longifilis (Avit and Luquet 1995;Baras et al 1998), fish placed under 12L:12D were essentially nocturnal. The present study provides further evidence that such an activity pattern was trained by light/dark alternation independently of the duration of each phase, and that starved fish show no activity rhythm under permanent illumination or darkness.…”

“…With respect to aquaculture, this study confirms the extreme plasticity of activity as well as capacities of adaptation of H. longifilis to various meal timings and photoperiod regimes, which both reinforce the suitability of this species for tropical and northern latitudes. It also supports the idea that rearing H. longifilis under permanent darkness may be profitable, assuming that food remains available over the entire 24-h cycle (Baras et al 1998).…”

“…Catfishes have been shown to be essentially nocturnal foragers (e.g. Bruton 1979;Avit and Luquet 1995;Boujard and Luquet 1996;Baras et al 1998) growing faster when fed at night than at other times with equivalent amounts of food (Kerdchuen and Legendre 1991). They can cope with low levels of dissolved oxygen and exhibit air-gaping behaviours at the water surface, although this activity seems to require more energy from the fish than directly extracting oxygen from water (Bevan and Kramer 1987).…”

-The swimming, air-gaping, and agonistic behaviours of Heterobranchus longifilis (318 ± 67 mm) were examined while fish were in a fasted state under 12L:12D and variable group size (2, 5, 10 and 15 fish) in a 1000-L aquarium. Fish exhibited a predominantly nocturnal activity pattern independent of group size. A diurnal peak of activity occurred, however, at the usual feeding time. A reduction in frequency of agonistic interactions was observed in larger groups. Five fish were then observed under 72L:0D and 0L:72D. The nocturnal activity pattern remained, contrary to the diurnal peak, and was independent of the duration of illumination or darkness. These results suggest the absence of biological clock in H. longifilis, although fish may somehow be influenced by past feeding experience.Behavioural plasticity in this species may provide potential for aquaculture in northern latitudes.

Desenvolvimento do surubim do iguaçu steindachneridion sp., Garavello (1991) AbstractThe experiment verified the development of Iguaçu´s surubim (Steindachneridion sp.) larvae, submitted to different diets in darkness. 35L-aquariums were used, in a completely randomized design, with five treatments and four repetitions. Each aquarium had 15 larvae with 8,35±0,85 mm and 6,75±0,64 mg, and the treatments were the following diets: Artemia(A); ration(R); zooplankton(Z); Artemia+ration(A+R); and zooplankton+ration (Z+R); After 29 days, the treatments A+R and Z+R was 1036 mg and 859 mg, respectively, significantly higher (P < 0,01), that A and Z, with 536 and 270 mg, respectively. In the treatment R there was no larvae survival, and presented high cannibalism (71%), which was also observed in other treatments, in smaller rates. This results led to the conclusions that the association of live and artificial diets in darkness provided best development, but it does not reduce the cannibalism.
