(1-9 months)

Species Primary Data Secondary Data Reference
Aphanius iberus From September until January 5.0 Fernandez-Delgado et al, 1988
Valencia hispanica From January to March 4.0 Caiola et al, 2001
Cobitis taenia Spermatogenesis occurs in males not onyl from May to July, but also in autumn. During winter, the testes were still filled with spermatozoa, with spermatogonia located in the wall of the lobules. Therefore the winter phase of quiscence is not folled by the depletion of the testes which remain full of sperm throughout the year 10.0 Marconato and Rasotto, 1989
Cobitis paludica From October to April 7.0 Oliva-Paterna et al, 2002

Cyprinus carpio Spermiogenesis is very short in carp [the completion of spermatogenesis is in october] 0.0 Billard et al, 1995
Cyprinus carpio Although the spermatogenesis is continuous there is a male gonadal cycle which increases in September and decreases around May 3.0 Crivelli, 1981
Cyprinus carpio Spermatogenesis was continuous and spermatogonia, psermatocytes, spermatids and sperm co-occurred in most testes throughout the spawning and non-spawning periods. Thus, males are euipped to spawn at any time during the year, but there is a defined gonadal cycle with a peak in Ig before the onset of spawning 0.0 Smith and Walker, 2004
