Many State, Federal, Tribal and private reporting agencies in the United States and Canada participate in a massive coastwide coded wire tagging effort to provide essential data for effective conservation and management of Pacific salmonid stocks. The coded wire tag (CWT) is widely used by fisheries agencies on the West Coast as a major information collection tool for stocks of salmon and steelhead (Oncorhynchus spp.).

This information provides the basis for monitoring the fisheries, allocating harvest rights among competing domestic users, improving productivity of hatchery stocks, establishing escapement goals, and satisfying Tribal treaty obligations. These data also play a key role in the U.S. – Canada Salmon Treaty allocations and management of transboundary stocks.

Resource management projects include hatchery contribution studies, differential treatment studies, fishery contribution studies, and a variety of other related studies which are important for fisheries management and research. 

Coded-wire tags help inform the below management and research questions:

Management 
(Basin-wide implications, on-going marking)

  • How many fish survived to adults?
  • Where do the fish go?  Should they be there?
  • When are they there?
  • How many and where are fish caught?
  • In a particular area where fish are caught, where did they come from?
  • Who caught the fish and how many?
  • Are enough of the right fish returning to reproduce the next generation?
  • What is going to happen next year?  Can we make changes to affect it?
  • Over time, are these fish runs increasing or decreasing?

Hatchery Evaluation
(Site-specific, on-going marking)

  • How many fish survive to adulthood?
  • Where do they go?
  • Who catches them?
  • Where do they spawn?
  • Are these fish fulfilling the reasons for which they were produced?
  • Is the hatchery program effective at producing the quality (age, size, weight) and number of fish needed?
  • Are these fish increasing or decreasing in numbers over time?
  • Are population characteristics changing (age, size of adults, male/female ratio, number of jacks, etc.)
  • What other fish are returning that don’t belong there?

Experimental Marking 
(fixed time studies)

  • Are fish being released at the right time?
  • Are fish being released at the right place?
  • Are fish getting the right diet?
  • Are there better ways to control disease?
  • Can we change things at the hatchery that:
  • Result in more adult fish?
  • Affect where the fish go?
  • Are there better ways to mark fish?
  • Is the right strain of fish being used?

Habitat Evaluation

  • Does the habitat produce quality smolts and the number of adults needed?
  • Over time, do habitat improvements result in more adult fish returning?
  • What other fish are showing up in the habitat that do not belong there?

Wild Tagging

  • Is it OK to use hatchery fish to evaluate a wild stock (specific locations)?
  • Do wild fish behave differently?
  • Do wild fish survive differently?

Overview of Coded Wire Tag Program including Applications in Fisheries Management and Research

Mass marking involves marking hatchery fish to enable them to be visually identified. This is usually done by removing the adipose fin from hatchery reared salmonid fish to differentiate them from wild or naturally produced fish. This enables the administration of mark-selective fisheries, in which only hatchery reared fish bearing the adipose fin clip are retained, and unmarked (presumably wild) fish, if caught, are released. The management goal of mark-selective fisheries is to reduce the harvest of naturally produced fish and therefore conserve wild fish populations.

Coded Wire Tags are produced as a spool of wire. Individual tags are cut from the spool for injection. The cut tags are 1.1 mm long and have a numeric code etched along the wire. Photo Credit: Northwest Marine Technology, Inc.

The invention of micro-sized coded wire tags (up to 1.5 mm length) that could be easily implanted into the tough nasal cartilage of juvenile salmonids (see figure) greatly changed marking studies because of the numerous advantages over fin clipping.

  • 1960’s, the first tags were developed and carried a dozen different colors and up to five longitudinal stripes allowing identification of different fish release groups.
  • 1971, binary coded tags were by Northwest Marine Technology, Inc. which replaced the color coded tags. Binary tags had improved readability and large  number of available codes.
  • 1990s, the new decimal coded tags were introduced further increasing the availability of unused codes while improving accuracy and readability. 

 

CWT Head Mold

 

Millions of juvenile salmon and steelhead are tagged annually. Chinook tagging levels are the highest (~ 50 million), followed by coho (~ 7 million). The remaining species including steelhead, chum, pink, and sockeye salmon tagging levels comprise ~ 3.0 million tags.

This massive tagging effort represents approximately 900 new tag codes each year. Hundreds of separate studies are involved, many of which include replicate groups as part of the basic design. Total cost is in excess of 7.5 million dollars annually. The cost per individual fish ranges between 12 and 15 cents, depending on local labor costs, logistics of tagging, and number of tags purchased for a given code.

Million of dollars are expended annually coastwide for tag recovery programs in U.S. and Canadian commercial and recreational fisheries. Tag recoveries from returning adult fish are on the order of hundreds of thousands per year.

Salmon and steelhead feed in the ocean from one to five years, depending on the species, before returning to spawn in their natural streams. Consequently, many millions of tagged fish from a number of brood years are present in the Pacific Ocean at any given time. As such, the multiplicity of tagging studies today represent a long term, multi-million dollar investment by State, Federal, Tribal, and private sector entities.

Some benefits of the CWT program:

  • One of the best ways to evaluate wild/natural stocks and their interactions;
  • Reliable method to evaluate harvest contribution rates, distribution, survival trends;
  • Management decisions based on CWT data acquired in real time activities can be evaluated with immediate results;
  • Changes in environment, hatchery practices, and harvest practices can be effectively tracked and factored into management decisions;
  • Contributes to resolution of tribal and international harvest allocation issues;
  • ESA concerns can be more effectively addressed;
  • CWT is currently the only stock identification tool which is Pacific coast-wide in scope and provides information for the entire life cycle of fish.

DSTC and WGDS Process

The specifications and definitions for the exchange of coded wire tag data for the North American is established by the Pacific Salmon Commission Data Sharing Technical Committee and its Data Standards Work Group. The data standards document captures all these specifications and definitions that inform the RMPC RMIS data fields and what data are submitted by CWT data providers to RMIS. The process for submitting, reviewing, approving and implementing a proposed modification related to data exchange is illustrated, and consists of the TCDS, the DSWG, and various PSC technical committees, including the Chinook, Coho and Selective Fishery Evaluation Technical Committees.
