Indian scientists have produced chimera fish in a laboratory experiment designed to investigate new breeding techniques for commercially valuable fishes.
Four scientists from the College of Marine Sciences at the Ocean University of China produced an inter-species chimera of the Rosy barb, Puntius conchonius and the Zebra danio, Danio rerio in their laboratory by taking cells from the Rosy barbs blastula-stage embryo and transplanting them into a Danio embryo at the same lifestage.
Of 473 transplants of Rosy barb cells into Danio embryos just 13 of the chimeras appeared "perfectly normal after one month', the scientists state.
The experiment is believed to be the first to show that it is possible to transplant blastula cells across cyprinid fish species to produce fish chimeras.
