Induced triploidy in Lepomis sunfish and assessment of uses for triploid hybrid sunfish using a risk/benefit model.

摘要

Genetically altered fish may interbreed or compete for environmental resources with natural fish populations, so their use in aquaculture or fisheries management poses environmental risks. Triploid fish are often sterile, alleviating the problem of interbreeding, but not necessarily other environmental risks. I developed and applied a risk/benefit decision model designed to determine appropriate fisheries uses for triploids. I tested 27 hydrostatic pressure shock combinations and successfully developed a triploid induction technique for hybrid sunfish (F
