| heal.abstract | The reproduction and fecundity of Aphanius fasciatus were studied in 2034 fish originating from three locations in the Mesolongi and Etolikon Lagoon system. The sampling stations differed in water temperature and salinity. The species exhibits early sexual maturation and is able to reproduce several months after birth. The reproductive effort (GSI) and histological studies of the ovaries indicate that reproduction is extended and lasts from April to July. Differences in the GSI values were observed between the sites. Fish originating from the sites with higher salinity has significantly lower GSI values and in addition, lay fewer eggs per unit of size (total length, body weight, age) than those from the other sampling sites. The maturation of oocytes stops when the environmental conditions are not satisfactory for the survival of eggs and larvae, and oocytes are subsequently absorbed. (C) 1998 Elsevier Science B.V.
