The invention relates to
pelteobagrus fulvdraco
sperm ultralow temperature freezing storage and
recovery method. Parent
pelteobagrus fulvdraco which is in good shape and good growth, has no
disease and is sexually mature is selected, 30Mug / kg LHRH-A2
intraperitoneal injection is carried out to induce
sperm increasing, after 36 hours,
dissection is carried out to obtain spermary, and the spermary is
cut into pieces in a clean
mortar cooled in a refrigerator at 4 DEG C in advance, the pieces are diluted by
Ringers solution in the proportion of 1:6, balancing is carried out for 30min at 4 DEG C, 10% methyl
alcohol is added, and mixing to be uniform is carried out, packaging is carried out, balancing is carried out for 10min 6cm above
liquid nitrogen surface, and balancing is carried out for 5min on the
liquid nitrogen surface, and then the product is thrown into
liquid nitrogen to be stored. Water bath ate 37 DEG C is carried out, activation solution SM is used for activation,
pelteobagrus fulvdraco roe is extruded into a container, frozen
sperm is added in drops in the sperm roe quantity ratio of 105:1, stirring to be uniform is carried out, then appropriate activation solution SM is added in drops, and stirring to be uniform is carried out, so that fertilization of roe is carried out. The sperm stored by the invention has high quality, has
insemination capability and has important theoretical significance and application value on seed quality saving, inheritance breeding, sustainable culture and
disease control of pelteobagrus fulvdraco.
