Twinning salmonids – a new source to knowledge about conjoined twins?
Conjoined twins are frequently observed in fish hatcheries. However, they normally die during the first feeding period and rarely achieve adulthood. In this study we investigated different types of conjoined salmonid twins at the yolk sac stage, and dissected a fully developed conjoined twin specimen obtained at Institute of Marine Research, Matre Research Station. This may contribute in filling in knowledge – gaps on this subject also in higher species.
