Article Synopsis
- The study examined how 17 alpha-methyltestosterone (MT) treatment and environmental salinity affect the growth hormone (GH) and insulin-like growth factor (IGF) axis in tilapia.
- Yolk-sac fry were divided into freshwater (FW) and seawater (SW) groups, with MT treatment applied in both environments; results showed that FW controls had the lowest GH mRNA levels, while SW fish on MT had the highest and were the fastest growing.
- GH mRNA levels correlated closely with fish size, indicating that GH mRNA is a better indicator of growth than plasma GH and IGF-I levels.
- Additionally, although prolactin (PRL) mRNA was higher in FW fish, MT treatment increased PR
