Feed utilization, growth and survival of Clarias gariepinus (Burchell 1822) fingerlings cultured under different photoperiods

Effect of photoperiod on locomotor activity, growth, feed efficiency and gonadal development of Nile tilapia

“…According to the authors, this high mortality is attributable to the low ability of these larvae to find food in environments with no light. However, Adewolu et al (2008) showed that fingerlings of African catfish, Clarias gariepinus, had better survival rates when reared under a photoperiod of 0L:24D. The longer survival in this condition can also be attributed to the feeding habit of this species, which feeds comfortably in the dark (Adewolu et al, 2008), dwelling in general, in river bottoms where the incidence of light is low (Feiden et al, 2006).…”

These differences in the survival of different species can be attributed to the extreme variation in the preferred photoperiod, which is species-specific and depends on the stage of development (Britz & Pienaar, 1992;Silva-Garcia, 1996;Boeuf & Bail, 1999;Adewolu et al, 2008).…”

Effect of dietary administration of the herbal additive siamweed (Chromolaena odorata) on growth performance and haematological changes in Clarias gariepinus fingerlings

“…The presence of flavonoid an active chemical in C. odorata has been confirmed (Vital 2008).This compound is a potent antioxidant (Taleb-contini 2006). The African catfish Clarias gariepinus is one of the most important cultured fish in Nigeria (Adewolu et al 2008). The objective of this study was to investigate the effects of dietary concentration of C. odorata leaf extract powder on growth, feed utilisation and haematological parameters of C. gariepinus fingerlings.…”

Histopathological effects of Cyperdicot and vitamin E supplementation on selected organs of Clarias gariepinus (Burchell, 1822) reared in a tropical fish farm in Nigeria

“…Clarias can be obtained throughout the year in Nigerian rivers and are anadromous (Akinwole and Faturoti, 2007;Adewolu et al, 2008). The fish is in high demand because of its flesh and good taste.…”
