Chapter 8, Problem 2CS

Summary Introduction

To determine:

What questions would be asked by a state employee before approving the release of laboratory produced, polyploidy species into a waterway. 

Introduction:

Controlling the overgrowth of aquatic vegetation by herbicides is an important issue in maintaining the public as well as private waterways. The diploid grass carp have been introduced in a state in 1963 to consume the vegetation. But they reproduced at an enormous rate. In 1980s, most states started using triploid grass carp, which are considered as an alternative. This is because of high sterility level and life span (seven to ten years) of triploid grass carp. At present, many states are in need of permission to use triploid grass carp for controlling vegetation and their containment is required in the water bodies to which they are introduced. In the future, the use of genetically modified organisms can help to achieve the required specific outcomes for human needs.
