Abstract
All the steroid treatments were efficient in producing either 100% male or 100% female populations demonstrating the production of androgen sex-inversed males and oestrogen sex-inversed females. The results of the GSD analysis suggested that most of the data fit to a ZZ/ZW model of sex determination. However, some crosses deviated from this model and other minor factors may be involved. Interestingly, minor effects of temperature and a limited but significant interaction between family and temperature have been observed. In conclusion, the present data suggest that a major ZZ/ZW genetic model is involved in turbot sex determination. Unexpected sex ratios deviating from this model are discussed, including a possible minor effect of environmental factors, such as temperature.
