pdf 07. The effect of stocking density, origin of eggs and water flow on growth, survival and body condition of Nile crocodiles ( Crocodilus niloticus)


Open Access


Authors: A. Zilber, D.N. Popper And Y. Yom-tov

Abstract: The effect of stocking density, origin of eggs and water flow regime on growth, survival and body condition of young Nile crocodiles was studied. No adverse effects of high densities, up to 15 animals/m1 was found. Animals hatched from eggs collected in nature had a slight advantage in growth. All tested parameters had no effect on survival, apart from increased mortality of 4-8 month old crocodiles kept at high density during their first cold season. Continuous water flow did not improve growth. Practical implications of these results are discussed.
