On the Development of the Periblastic Sinus during the Embryogenesis of the Masked Greenling Hexagrammos octogrammus and Whitespotted Greenling H. stelleri (Scorpaeniformes: Hexagrammidae)

Аннотация

Embryonic development observations of the masked greenling H. octogrammus and the whitespotted greenling H. stelleri inhabiting the Tauiskaya Bay of the northern part of the Sea of Okhotsk have been performed under laboratory conditions. Both fish species developed a periblastic sinus during the fifth stage of embryogenesis; this has been observed for the first time for the representatives of Hexagrammidae family.
