Understanding the Potential Biological Removal Level in Marine Law

Definition & Meaning

The potential biological removal level refers to the maximum number of marine mammals that can be removed from a specific population without hindering its ability to recover and maintain a healthy population size. This level is determined by several factors:

  • The minimum population estimate of the marine mammal stock.
  • Half of the maximum productivity rate of the stock, particularly when the population is small.
  • A recovery factor that ranges from 0.1 to 1.0, reflecting the stock's ability to recover from removals.

Real-world examples

Here are a couple of examples of abatement:

For instance, if a population of a particular marine mammal is estimated to be 1,000 individuals, and the maximum productivity rate is estimated at 0.1, the potential biological removal level would be calculated as follows:

  • Minimum population estimate: 1,000
  • Productivity rate: 0.1 (or 10 percent)
  • Recovery factor: 0.5 (hypothetical example)

Thus, the potential biological removal level would be 1,000 x 0.1 x 0.5 = 50 animals.

Comparison with related terms

Term Definition Difference
Optimum Sustainable Population The population size that allows for the maximum productivity of a species. Potential biological removal level focuses on the number of animals that can be removed, while optimum sustainable population refers to the ideal population size.
Maximum Theoretical Productivity Rate The highest possible growth rate of a population under ideal conditions. This term is a component of calculating the potential biological removal level, but does not account for actual removals.

What to do if this term applies to you

If you are involved in marine mammal management or conservation, it's essential to understand the potential biological removal level for the species you are working with. You may want to consult with environmental experts or legal professionals. Additionally, US Legal Forms offers templates that can assist you in managing related legal paperwork effectively.
