摘要: Abstract We examined the effect of temperature in European silver eels during their maturation induced by injections carp pituitary extract on endocrine parameters: fshβ and lhβ expression, plasma 17β-estradiol (E2) vitellogenin, estrogen receptor 1 (esr1), vitellogenin 2 (vtg2) expression liver. A variable thermal regime (T10) that increased from 10° to 14° 17 °C was compared with a constant 20 °C (T20) 12 weeks. T10 caused faster development until week 8, higher fshβ, lhβ, esr1 E2 levels. The results strongly suggest is inducing endogenous FSH level which increases circulating vitellogenesis. an profile vitellogenic hormonally matured eel females were more similar observed other naturally maturing fish.
