Early life stages (ELS) of Clarias gariepinus were found to be less sensitive to acute dieldrin toxicity than ELS of Nile tilapia, Oreochromis niloticus; 96 h LC50 for 37 day old fry were 11.7 and 4.95pg/l, respectively.

In this study, early, post-embryonic and larval developmental stages of C. gariepinus were examined chronologically and described. At the fingerling stage they were very small. Supawadee Poompuang. Required fields are marked *. Growth of O. niloticus fry was significantly reduced in 22.4 pg/l dieldrin whereas growth of C. gariepinus fry was unaffected. Seven embryonic periods were characterized for timing and features: zygote, cleavage, blastula, gastrula, segmentation, pharyngula and hatching. Our results suggest that in the early stages of invasion, catfish display higher condition and growth rates by profiting from relatively unexploited resources (large fish and, secondarily, waterbirds), shifting to other prey (and thus reducing mean growth) in the late invasion stagesThis study was fi nanced by the Spanish Ministry of Science and Technology (REN2003-00477 On his farm, fishes are divided into groups according to their stages of growth and weight: the first type is 15 kg, the second one – 12 kg and the third one – 10 kg.
