This study was conducted to investigate the efficacy of dry shipper for the cryostorage of silver barb (Barbodes gonionotus) sperm, the subsequent risk of bacterial cross-contamination, and the effects of Aeromonas hydrophila on post-thaw sperm. Semen was diluted with calcium-free Hank's balanced salt solution containing 10% MESO, frozen at -8 °C/min and stored for 14 d in a dry shipper. A significant decline (P < 0.

This study was conducted to evaluate the effects of methods of semen collection on sperm quality and bacterial composition of post-thawed semen of silver barb (Barbodes gonionotus). Semen collection methods consisted of four treatments: (1) hand-stripping of abdomen without rinsing of urogenital area with water, (2) hand-stripping of abdomen after rinsing of urogenital area with water, (3) catheterization without rinsing of urogenital area with water and (4) catheterization after rinsing of urogenital area with water.

We focused on freezing of common carp sperm utilizing a practical and inexpensive protocol for aquaculture. Sperm were diluted 1:1 in one of six extenders (common carp sperm extenders; CCSE 1-CCSE 6) containing three types of cryoprotectants (dimethyl sulfoxide; DMSO, methanol; MET and propylene glycol; PG) at a final concentration of 10%, and frozen at a rate of 10°C/min from an initial temperature 25 to -40°C before storage in liquid nitrogen.

Here we report the identification and expression of an amphioxus TRP14 gene, named AmphiTRP14, the first such data in a non-mammalian organism. AmphiTRP14 consists of a 372-bp open reading frame coding for a 123-amino-acid protein with a calculated molecular weight of 14 kDa.
