T-Bar tags - convenient, cost-effective and popular
Hallprint's range of T-bar anchor tags are without doubt the most popular tag types produced by Hallprint. They represent a generational improvement in fish tag design with a single moulded construction that has a protective outer sheath around the coloured and individually numbered marker.
T-bar tags are popular on fish, crustacean and even some shellfish species where large numbers of fish may need to be tagged in a short space of time and/or holding time is critical for fish survival.
T-bar anchor tags are available in a wide range of colours in both fine anchor (TBF) and standard anchor (TBA) versions. TBA tags may have either one or two lines of print (TBF one line only). Please note that both exposed filament length and marker length can easily be varied on all T-Bar tag types to suit your custom requirements (see below).
New - in exciting news for researchers we have developed an extra heavy duty T-Bar tag (type TBXH) for larger finfish above 35 cm in length. With a robust 16 mm length nylon T-bar anchor and tough 0.80 mm diameter nylon monofilament these are expected to be a viable option to plastic tipped dart tags for larger finfish such as tuna and salmon allowing faster tag deployment in sequential number order.
We are also able to custom print in numerous languages (subject to font provision for no additional charge.
As a general rule only, fine anchor tags (type TBF) are suitable for most Finfish and crustaceans according to the following optimal size ranges -
Finfish (between dorsal or anal fin rays) 10 cm total length - 20 cm total length
Rock lobster (through moult suture) 3 cm carapace length - 6 cm carapace length
Crabs (through moult suture) 4 cm carapace width - 7 cm carapace width
Standard anchor tags (type TBA) are suitable for most Finfish and crustaceans according to the following optimal size ranges -
Finfish 15 cm total length - 35 cm total length
Rock lobster 6 cm carapace length to max. size
Crabs 7 cm carapace width to maximum size
Average marker length is around 20 mm for TBF tags and 30 mm for TBA tags but can vary from around 12 mm to around 40 mm for TBF tags and from around 12 mm to 60 mm for TBA tags. The length of exposed filament is normally around 15 mm for TBF tags and 20 mm for TBA tags. Exposed filament lengths of between 10 mm and 40 mm are possible for both tag types.
Please ensure that both the exposed filament length and the marker length preferred are provided when requesting quotations or ordering tags.
