| Abstract |
Structural changes of two lipovitellins (Lvs) derived from two forms of vitellogenin (Vg), Vg A and Vg B, were examined during vitellogenesis and oocyte maturation in barfin flounder, Verasper moseri and walleye pollock, Theragra chalcogramma. From the results, we suggest that the quantitative ratio of incorporated Vg A to Vg B in post-vitellogenic oocytes regulates the buoyancy of the spawned pelagic eggs |
