Tiny Zebrafish, Huge Impact: Grass Carp Reproduction Accelerated 20-Fold (IMAGE)
Caption
Most aquaculture species have long maturation periods that limit breeding efficiency. Here, researchers from the Institute of Hydrobiology, Chinese Academy of Sciences, report in Science China Life Sciences with a cover story of an ultra-fast surrogate reproduction strategy: female germline stem cells from grass carp (Ctenopharyngodon idellus), a species requiring ~5 years to mature and >20× longer and ~20,000× heavier than zebrafish, were transplanted into zebrafish (~3 cm, 3-month maturation), producing all-female grass carp within just three months, dramatically shortening the breeding cycle.
