Hallprint Fish Tagging

Hallprint Fish Tagging What is a Fish Tag? Many of these tag types can now be custom printed and/or fitted with radio frequency identification (RFID) or PIT tag modules.

Australian based manufacturer and retailer of proven premium quality and individually numbered external fish, shellfish and crustacean tags (including some with optional RFID capabilty) and distributors of Australian made Scielex measuring boards. Fish tags are used by research scientists and other organisations to assess and monitor life history aspects of fish, crustaceans and shellfish includin

g studies on growth rates, movement patterns and mortality estimation. Hallprint's range of external fish tags are exceptionally long-lasting individual identification marks suited to the harsh marine environment and available in a huge range of colours and sizes.

From Hallprint Managing Director, David Hall -

Last month son Anthony & I visited the Freshwater Biological Association (FBA)’s Species Recovery Centre on the shores of Lake Windermere in Cumbria.

The FBA is a not-for-profit charity doing some amazing work with the help of citizen scientists.

At almost zero notice assistant pearl mussel officer Jodie Warren kindly showed us around the facility where thousands of juvenile endangered freshwater pearl mussels were being held in trays and tanks in a flow-through system sourcing high quality nutrient rich water from the lake.

What a great program this is!

The freshwater pearl mussel Margaritifera sp. is an endangered species that us actually one of the world’s longest living invertebrates living for well over a hundred years! The mussels are bred utilising salmon fingerlings as an intermediary host. The third and last photo also shows some of the 40 odd original “broodstock” mussels that were tagged some 12-15 years ago - on the last photo you can still see some of the original white tags.

The juvenile mussels are reared and only tagged with our glue-on tags when they are a few years of age - the tagged mussels shown in my hand are around 5 or 6 years of age and finally ready to be released to the wild.

Jodie told us how each of the river systems in Cumbria has a different genetic strain of mussel so they must keep each strain separate during the breeding and rearing periods. Apparently one of the rivers involved, the River Kent, is believed to have had only 12 individuals left in the wild so production of this or rather a closely related strain is an obvious priority - the aim is to get the number to 100 quickly and several thousand before too long!

The 5000th tagged mussel deployed from the hatchery was released in the River Kent only last month - https://youtu.be/7CPRVlxlsxs

It was so good to see our company’s tags playing such an important role in the preservation of a critically endangered species on our travels!

Tag # W54448 was placed in a 18 cm hatchery produced juvenile barramundi on 21 April 2018. The fish was among a number released in Lake Monduran in Queensland that year by a local stocking group as part of the long running Suntag program.

Remarkably this now not-so-little fish was recaptured this week on 16 September at 101 cm length, a growth of 83cm. It was released to be caught again.

The little fish might have changed a lot after 7.4 years in a good paddock but the tag looked almost unchanged - and more importantly perfectly readable.

Suntag in Queensland is the largest volunteer tagging database in the world with 945,000 fish tagged and 73,500 recaptures since 1987. Awarded “Best Angler-Led Data Collection Project” at the World Recreational Fishing Conference in 2023, this has only been made possible through countless thousands of hours by volunteer taggers and of course fish tags from Hallprint that are proven to stand the test of time in a rugged environment.
