The total cortisol content in tilapia was 55 pg immediately following fertilization, then decreased abruptly and maintained a lower level of 10-20 pg until hatching; after hatching the cortisol content increased to 50 pg by the 7th day. Fertilized eggs were incubated in either 32% saltwater or fresh water and sampled at various developmental stages. Both groups showed dramatic changes in cortisol content following development. However, no significant difference in the cortisol level was found… CONTINUE READING
