摘要: To evaluate the effect of age and body size on the development and maturation of male Penaeus monodon, P. monodon males from the same cohort at age of 100, 120, 135, 156, 175, 205, 236 days in a tidal pond (TP), and 100, 123, 140, 157, 185, 258 days in an earthen pond (EP) were examined. The minimal body size and age of males from TP and EP that produced spermatophore were investigated. The earliest time of spermatophore production of the TP males (120 days) was significantly earlier (P0.05) among different age groups except for the 185- and 258-day-old (EP), the percentages of normal and abnormal sperm were significantly different. The results indicated that it is important to consider the age and size of males and the culture conditions under which domesticated male broodstocks will be obtained.
