Catch Per Unit Effort Calculator


Calculating catch per unit effort (CPUE) is essential in fisheries management to assess the productivity of fishing operations. This article provides a comprehensive guide on using a CPUE calculator to efficiently estimate fishing yields.

How to Use

To utilize the CPUE calculator effectively, follow these steps:

  1. Input the total catch in weight units.
  2. Enter the fishing effort, typically measured in hours or days.
  3. Click the “Calculate” button to obtain the CPUE value.


The formula for calculating CPUE is:

Example Solve

Let’s consider an example where the total catch is 500 kg, and the fishing effort is 100 hours.


Q: What is CPUE?
A: CPUE stands for catch per unit effort, which is a measure used in fisheries management to evaluate the efficiency of fishing operations.

Q: Why is CPUE important?
A: CPUE provides insights into the abundance of fish stocks and helps in making informed decisions regarding fishing regulations and resource management.

Q: Can CPUE vary over time?
A: Yes, CPUE can vary based on factors such as changes in fishing techniques, environmental conditions, and fluctuations in fish populations.


In conclusion, the CPUE calculator offers a convenient tool for fisheries managers and researchers to assess the productivity of fishing activities. By accurately calculating CPUE, stakeholders can make informed decisions to ensure sustainable fishing practices and the conservation of marine resources.
