H.R. 1917: Great Lakes Mass Marking Program Act of 2025

This legislation, known as the Great Lakes Mass Marking Program Act of 2025, aims to establish a comprehensive program for marking hatchery-produced fish in the Great Lakes basin. Here is a breakdown of the key components:

Purpose of the Program

The primary goal of the Great Lakes Mass Marking Program is to improve the management and understanding of fish populations in the Great Lakes, particularly in relation to:

• The balancing of hatchery-produced fish with wild fish populations.
• Supporting the recovery of native fish species.
• Enhancing recreational and commercial fishing opportunities.

Background and Rationale

Congress has noted several concerning changes in the Great Lakes ecosystem, including:

• The introduction of invasive aquatic species.
• Alterations to the food web affecting fish populations.
• A decrease in the abundance of prey species for predatory fish.

Due to these changes, there is a recognized need for a scientific, collaborative approach to fish management that can help address these challenges.

Implementation of the Program

The program will be managed by the United States Fish and Wildlife Service and will involve:

• Mass marking of hatchery-produced fish using modern technology to enable better understanding of fish populations.
• The collection of data on the effectiveness of hatchery operations and fishery management actions.
• Collaboration with State, Tribal, and federal agencies involved in fish management.

Authorized Actions

The Director of the United States Fish and Wildlife Service will have the authority to:

• Purchase necessary equipment for tagging operations.
• Hire additional staff to support the program’s objectives.

Data Availability

Data collected through the program will be made available to relevant fish management agencies to:

• Enhance understanding of fish population dynamics and management effectiveness.
• Support fish community restoration objectives and habitat management efforts.
• Improve economic outcomes for both Tribal and commercial fisheries.

Funding

The bill proposes an appropriation of $5 million annually for five fiscal years (2026 through 2030) to support the implementation of the program.
