Questions and Answers

What is the primary purpose of using genetic markers in fisheries science?

  • To determine the water quality in fish habitats
  • To select fish for aquaculture operations
  • To identify the origin of individual fish (correct)
  • To study the behavior of fish populations
  • How does genetics contribute to the conservation of endangered fish species?

  • By determining the average size of fish populations
