Abstract
The effects of ageing oocytes for 6 h before fertilization in the Euro pean catfish Silurus glanis are compared with the same experiment unde r normal conditions (stripping and Fertilization immediately after ovu lation). Fertilization rate and hatching rate are lower in the aged gr oups, while the percentages of malformed larvae and chromosomal abnorm alities are significantly higher. Several kinds of abnormalities are d escribed in detail. (C) 1998 The Fisheries Society of the British Isle s.
