Chromosome-set manipulation in tilapia — techniques, problems and prospects

Abstract

In recent years a great deal of research has been conducted on chromosome-set manipulation (polyploidy and gynogenesis) in a number of tilapia species. The rationale for this work has been to produce sterile progeny for culture; for sex manipulation; and to produce highly inbred or cloned lines for crossbreeding and for research purposes. Haploid, gynogenetic diploid, triploid and tetraploid genotypes have been produced in a number of laboratories and yet this research has been of little or no discernible benefit to the world-wide tilapia culture industry. Techniques for induction and verification of chromosome-set manipulation are reviewed and the potential applications of these are critically discussed.
