Transcriptomic changes in the reproduction control system of eel (Anguilla japonica) in response to salinity change and SPE injection

Artificial sexual maturation of female eel is induced by repeatedly injecting SPE (salmon pituitary extract) after acclimatizing from freshwater to seawater. However, However, biological changes caused by these treatments have not been fully understood.In this study, wild female eels were accommodated under four different conditions to investigate transcriptomic changes in the HPG (hypothalamus-pituitary-gonad) axis of eels induced by different salinity and SPE injections.
