Diurnal periodicity in testicular activity in the Japanese flounder Paralichthys olivaceus

Testicular activity, as represented by the amount of each type of testicular germ cell in the seminal lobules, and the serum levels of three major male teleost steroids--testosterone (T), 11-ketotestosterone (11-KT), and 17 alpha ,20 beta -dihydroxy-4-pregnen-3-one (17 alpha ,20 beta -DP)--were inve...

Zusammenfassung:	Testicular activity, as represented by the amount of each type of testicular germ cell in the seminal lobules, and the serum levels of three major male teleost steroids--testosterone (T), 11-ketotestosterone (11-KT), and 17 alpha ,20 beta -dihydroxy-4-pregnen-3-one (17 alpha ,20 beta -DP)--were investigated during the daily spawning cycle of the male Japanese flounder Paralichthys olivaceus.
