Resumo(s)

The oocytes of marine pelagic teleosts swell abruptly by hydration during the reinitiation of meiosis (oocyte maturation) before ovulation. This process renders the eggs and early embryos buoyant in sea water, allowing their survival and dispersal in the ocean (1, 2). The major osmotic effectors for water uptake are free amino acids derived from the proteolysis of the oocyte major yolk proteins (3), but the membrane-associated mechanisms involved remain unknown.
