Abstract: The skin of Crocodylus niloticus is one of the best among alligator species. Understanding proper rearing of crocodiles and processing of their skins is very essential for farmers because quality is very crucial in marketing the skins. A study was done to assess the effects of processing stages and pond type on crocodile skin size and quality. A total of 400 skins were assessed, of which 200 skins were from each pond. The skins had their belly sizes measured before and after being subjected to the processing stages. The skins were also graded in terms of quality after every stage. Data analysed using a paired t-test for initial and final skin size within and across ponds showed that there was a significant (P =0.00) effect of pond type on both initial and final skin size. Earth ponds showed high skin size but had a low quality compared to cement ponds. Further, there was a significant effect of processing stages on final quality (P value =0.00). The conclusion of the study was that crocodile rearing environment and skin processing techniques influence final size and quality of skins. As such, it was recommended that producers monitor rearing conditions and pre-tanning processing stages in order to improve skin quality, minimise losses due to shrinkage and thus maximise profits.
