Salinity on artificial reproduction of silver catfish (Rhamdia quelen)

Abstract

Attempting to improve reproduction performance and ichthyo prophylaxis, this study evaluated the effects of maintaining silver catfish (Rhamdia quelen) broodstock in different saline concentrations (0, 2, 4, 6 and 8‰)

Effect of Different Salinity Level on Breeding, Fertilization, Hatching and Survival of Nile Tilapia, Oreochromis niloticus (Linnaeus, 1758) in Captivity

“…These results are in agreement with the findingds of the present study. Evidence to support this is available in another study of Martins et al (2015) who investigated the effect of salinity on artificial reproduction of silver catfish (Rhamdia quelen) and reported 85%-93% fertilization rate. Similar results have been reported by Abdel-Hakim et al (2008).…”

“…Akinwande et al (2012) reported hatchability rate 79.1%-83.3% in Clarias spp. Martins et al (2015) while studying on some other fish species reported significant results (83.3%) at 0‰ salinity for silver catfish, Rhamdia quelen. Young-Sulem et al (2008) obtained maximum hatchability (65.3%) at various turbidity levels for Clarias gariepinus.…”
