Variations of estradiol-17β and testosterone levels correlated with gametogenesis in the gonad of Zhikong scallop (Chlamys farreri) during annual reproductive cycle

Abstract: To assess the potential roles of sex steroids in modulating reproductive processes in the Zhikong scallop (Chlamys farreri (Jones and Preston, 1904)), variations in estradiol-17␤ (E2) and testosterone (T) levels in gonads were examined monthly from January to December 2012 by enzyme-linked immunosorbent assay (ELISA). The mean concentrations of E2 and T in gonads ranged from 75.07 to 666.24 pg/g and from 91.09 to 506.28 pg/g, respectively. Concentrations of E2 were significantly higher in ovaries than in teste… Show more

“…63 and Liu et al . 64 , the testes of C . farreri used in our study were grouped into three stages, the proliferative stage (GSI = 4.07 ± 0.72), the growing stage (GSI = 6.90 ± 0.58) and the mature stage (GSI = 9.76 ± 1.46).…”

“…Hasil tersebut didukung oleh hasil dari Wang and Kroll (2004) yang memberikan suntikan 17βestradiol pada kerang Placopecten magellanicus dan terbukti mampu meningkatkan pertumbuhan oosit, serta Kruatrachue et al (1996) pada siput bekicot (Achatina fulica) yang meningkatkan jumlah oosit ovotestis. Korelasi positif antara 17βestradiol dengan diameter rata-rata oosit menunjukkan bahwa estradiol terlibat erat dalam oogenesis dan vitelogenesis (Liu et al, 2014). Paparan estradiol terhadap gonad akan merangsang vitelogenesis pada oosit dan memberikan respon perkembangan yang lebih tinggi.…”
