Reproduction of Deepwater Redfish Sebastes mentella on the Flemish Cap Bank by
Based on the data from research in 1983-2002, the results from the study of deepwater redfish sexual maturation, of the annual cycle of gonad development, the sex ratio and reproduction of the deep-water redfish Sebastes mentella Travin 1951 occurring on the Flemish Cap Bank (Div. 3M) are presented....
