Induction of sex inversion in juvenile grouper, Epinephelus malabaricus, (Bloch and Schneider) by bi-weekly injections of 17 alpha-methyltestosterone
Share
นามธรรม
Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the need to do induced sex inversion studies. In Epinephelus tauvina and E. fario, sex inversion was successfully induced by oral administration of 17 alpha-methyltestosterone (MT). This paper reports on the induction of sex inversion of juvenile grouper E. malabaricus using bi-weekly intramuscular injections of MT.

Possible application of mibolerone for induced sex inversion of grouper Epinephelus coioides
Quinitio, Gerald F.; Tan-Fermin, Josefa D.; Nagai, Akimasa (Japanese Society of Fisheries Science, 2001)Thirty immature juvenile grouper Epinephelus coioides (19-168 g bodyweight, BW) were randomly stocked in four units 6 t tanks to determine if mibolerone can be used to induce sex inversion in groupers. After acclimatization ... -

Gonadal response of juvenile protogynous grouper (Epinephelus fuscoguttatus) to long term recombinant follicle-stimulating hormone administration
Palma, Peter; Nocillado, Josephine; Superio, Joshua; Ayson, Evelyn Grace de Jesus; Ayson, Felix; Bar, Ido; Elizur, Abigail (Oxford University Press, 2019-03)The role of follicle stimulating hormone (FSH) in the gonadal development of protogynous hermaphroditic grouper (E. fuscoguttatus) was investigated. Recombinant giant grouper (E. lanceolatus) FSH (rggFSH) was produced in ...
