Abstract: Abstract:To understand the maturation process,histological,microscopic,and macroscopic observations were conducted on the ovaries of yellowfin tuna(Thunnusalbacares)collected from the landings of Taiwanese inshore longliners operating inthe southern waters of Taiwan.The development of ovaries during maturation can be grouped into fivephases.In the study,no immature ones were found,an indication that the maincatches of yellowfin tuna by the inshore longliners were adults.Based on the polymodal frequency distribution and the different developingstages of the oocytes simultaneously existing in the ovary of matured fish,thespecies was considered to be a multiple and asynchronous spawner.Oogenesis of yellowfin tuna is similar to most of teleostei.It can be broadlydivided into 13 growth stages.A correlation between the maturity phase and themost advanced oocytes stages showed that the developing phase corresponds to theearly and late peri-nucleolus stage;the maturing phase to the primary andsecondary yolk globule stage;the full maturity phase to the migratory nucleusstage and ripe egg stage;the spent phase to the degenerated oocytes at the yolkvesicle stage,primary yolk globule stage,secondary yolk globule stage,andtertiary yolk globule stage.
