Biotechnology is used in many ways in agriculture. Agricultural biotechnology companies work to supply farmers with tools to increase the yield of plant and animal products, while lowering the costs of production.
Agricultural biotechnology can also include production of plants such as orchids for ornamental purposes and plants that can be used for fuel production (biofuels).
To accomplish these goals, biotechnologists develop products to protect animals and crops from disease and help farmers identify the best animals and seeds to use in selective breeding programs. For example, a commercial fish farm might raise fish like salmon, tilapia, or catfish. If the fish were infected by certain viruses, the fish would die and the farm would lose money. To prevent infections, fish farmers use vaccines, developed through biotechnology.
