Sex Determination In Tasmanian Atlantic Salmon

摘要

The maturation of Atlantic salmon prior to harvest is costly, so since male salmon are more likely to mature early than female fish, the salmon industry in Tasmania relies on all-female production. This requires sex reversal of XX females to become phenotypic neomales, which are then crossed with XX females. Tasmanian aquaculturists joined researchers from Australia and Canada to develop a genetic test to determine salmon sex and remove identification uncertainties. Three chromosomes were identifiedas potentially linked to sex.
