The invention discloses a method for collecting and
dyeing sperms of Chinese prawns, and belongs to the technical field of
germplasm resource protection and utilization. The method comprises the following steps:
grinding Penaeus chinensis
spermatophore with outer membrane removed in a glass
homogenizer, adding sterilized
artificial seawater,
grinding until the solution becomes milky white, and filtering to obtain
sperm; and mixing the
sperm with
eosin-nigrosine dye liquor, and standing to obtain the dyed Chinese
prawn sperm. The collecting and
dyeing steps are simple and easy to operate, the whole process is short in time consumption, small in sperm damage, visual in effect and high in sperm
survival rate. The
staining method disclosed by the invention is not only suitable for
staining fresh sperms, but also can be used for
staining the thawed and resuscitated sperms after
cryopreservation, the staining observation after thawing is clear, and the sperms are not easy to crystallize.
