Study Notes

Fish Biotechnology - Introduction

  • Fish are cold-blooded vertebrates that live in water and have fins.
  • Many fish live in lakes and oceans.
  • Biotechnology is any technological application that uses biological systems, living organisms, or their derivatives, to make or modify products or processes for specific use.
  • Aquaculture is the farming of aquatic organisms. It's also sometimes called aquafarming.
  • Aquafarming is the controlled or semi-controlled propagation of aquatic organisms.
  • Fish farming raises fish for personal use or profit, sometimes called fish culture. This commonly involves tanks or enclosures where fish are raised for food.

Aquaculture Applications of Biotechnology

  • Biotechnology in aquaculture can help with control of reproduction.
  • Biotechnology can also improve growth enhancement.
  • Biotechnology assists in genetic characterization.
  • Control of diseases in aquaculture is an application of biotechnology.
  • Metabolic engineering is another biotechnological application.
  • Transgenesis (genetic modification) is another possible application.
