Several genetic manipulation techniques are being actively investigated in a number of fish species. Induced triploidy can be a useful method of generating sterile individuals. Homozygous diploid individuals can be generated and used to rapidly generate homozygous inbred lines. Both induced triploidy and induction of homozygous diploids do not appear to be possible in mammals. Gene transfer technology is just beginning to be developed for fish; it may have a number of valuable applications. Gene banking faces some difficulties in fish that are not present in mammals. Fish egg and embryo cryopreservation has not yet been successful, and new methods may need to be developed to reconstitute fish strains from cryopreserved sperm or embryonic cells.
