In genetics, a molecular marker (identified as genetic marker) is a fragment of DNA that is associated with a certain location within the genome. Molecular markers are used in molecular biology and biotechnology to identify a particular sequence of DNA in a pool of unknown DNA.


It has 5 applications in fisheries and aquaculture:

  1. Species Identification
  2. Genetic variation and population structure study in natural populations
  3. Comparison between wild and hatchery populations
  4. Assessment of demographic bottleneck in natural population
  5. Propagation assisted rehabilitation programmes.However,there still exists some limitations.[1]
