[Zbrafish] ratio males/females

[Sophie Louwette]

Dear all,

 

Lately we are having problems with raising our zebrafish. The survival rate is fine (70%-80%) but the majority of them are males. We keep our fish on 26°C and not too crowded. I was wondering if there are correlations between temperature and density and the ratio of females/males. Maybe you can give us some advice on this issue. 

 

Best regards,

Sophie
