Observations on embryos and embryonic development from an egg mass of the jumbo squid Dosidicus gigas spawned under captive conditions

Descripción del Articulo

Egg masses were spawned by a jumbo squid Dosidicus gigas (mantle length 37.5 cm) held in a tank (500 L) on board the R/V Kaiyo Maru during a joint Japan-Peru cruise in Peruvian waters during December 2011– February 2012. Part of an egg mass was collected and incubated in an aquarium (10 L) maintaine...

Part of an egg mass was collected and incubated in an aquarium (10 L) maintained at 20 °C. The eggs had a unique jelly envelope surrounding the chorion. The diameter of the jelly envelope was more than twice the diameter of chorion. It remained clearly visible until the embryos reached developmental stage 18.

Parte de la masa de huevos se recolectó e incubó en un acuario de 10 litros y conservó a 20 °C. Los huevos tenían una envoltura gelatinosa única alrededor del corion. El diámetro de la envoltura gelatinosa era más del doble del diámetro del corion, el que permaneció claramente visible hasta que los embriones alcanzaron la etapa de desarrollo 18. La mayoría de los huevos estaban fertilizados y eclosionaron (Etapa 30) 6,5 días después del desove a 20 °C.Instituto del Mar del PerúInstituto del Mar del Perú20182018-09-10T17:29:51Z2018-09-10T17:29:51Z2018info:eu-repo/semantics/articleapplication/pdfBol Inst Mar Perú. 33(2) 2018: p. 153-15903787702https://hdl.handle.net/20.500.12958/3248Instituto del Mar del Perú - IMARPERepositorio Digital IMARPEreponame:IMARPE-Institucionalinstname:Instituto del Mar del Perúinstacron:IMARPEspaBoletín IMARPE;33(2), 2018info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/4.0/oai:repositorio.imarpe.gob.pe:20.500.12958/32482021-06-11T08:20:35Z
