Abstract
The use of a semi-natural medium (Eagle's MEM supplemented with chicken embryo extract) appears to be satisfactory for ovarian and testicular fragment cultures of Carassius auratus. The male germ cells show a normal degeneration which might be attributed to a lack of pituitary hormones: gonadotropic and, possibly, somatotropic hormone. The ovarian fragments maintain a normal organization during 21 days of culture. Only the oocytes in late vitellogenesis massively atresiate at the beginning of culture. The addition of fetal bovine serum to this medium produces surprising effects on the testicular explants, particularly on the spermatogonial mitoses. This might be attributed to the presence of STH and androgen in the serum. The modifications of ovarian explants, on the other hand, are identical to those observed with Eagle's MEM supplemented with chicken embryo extract. M 199 has been tested as a synthetic medium; the preliminary results are encouraging. Testosterone, when added to the semi-natural medium, permits complete spermatogenesis in the testicular fragments during the 21 days of culture, but does not produce any effect on the ovarian explants.

Abstract
Histological examination of gonads from teleosts, cultivated in vitro on an agar medium containing glucose and chick embryo extract shows the continuation of the germinal activity for at least 21 days. The influence of different factors: stage of maturation at the time of explantation, quantity of nutrient available, and transfer on fresh media are checked. The best results are obtained for ovaries containing only young oocytes, i.e. before any vitellogenesis or when it has just started, and for testes in which spermatogenesis is well advanced, i.e. when there are numerous spermatozoa. Results do not seem to be improved by frequent transfers.
First attempts of association with pituitary gland or gonads of the opposite sex are reported.
