AutoFish Systems by Mallory Bailey https://padlet.com/bailey92/cm0oznhe75l7 Tagging Fish Faster Than Ever en-us 2019-03-03 18:59:17 UTC 2025-04-15 16:43:08 UTC hello@padlet.com What is AutoFish Systems? bailey92 https://padlet.com/bailey92/cm0oznhe75l7/wish/337260435 AutoFish Systems is a mobile fish tagging laboratory made for the mass tagging or marking of fish species, making the process faster, more comprehensive, and cost effective.

The AutoFish System uses Coded Wire Tags or CWT which injects the tag into the snout of the fish. The wire tags range in size but are considered minimally invasive to the animal (Holt, Cox, and Sawanda, nd).

After the fish has been tagged, it will swim through a pipe on its way to the exit where a magnetic sensor can check to see if the tag was put in correctly so that it can be read in the future (Tabor, 2010).

Ontario Federation of Anglers and Hunters (OFAH) has used the AutoFish System to tag fish being stocked in Lake Ontario (Moorhouse, 2008)

The AutoFish System is mainly used in hatcheries for large quantities of stock fish such as salmon and trout. I cannot find any information on this system being used for tagging non-stock fish. 

Attached below is an interesting video from Idaho Fish and Game and Pacific States Marine Fisheries Commission on using the AutoFish System (2017.)]]> 2019-03-03 19:18:51 UTC https://padlet.com/bailey92/cm0oznhe75l7/wish/337262657 Strengths Of The AutoFish Systems bailey92 https://padlet.com/bailey92/cm0oznhe75l7/wish/337263592 The main strength of the AutoFish is the ability to tag mass amounts of fish, sometimes up to 60,000 fish per day (Tabor, 2010). 

Fish being tagged by the mobile system do not have to leave the water which greatly reduces the stress put on the animal. Also with the system being mobile it can be used in many different areas and jurisdictions with a shared cost of use. 

The Coded Wire Tags used on the fish have not be shown to have any affect on the fish and are considered to be minimally invasive. (Blankenship and Thompson, 2003)

Currently The AutoFish system is used mainly for stock fish like salmon and trout and so that could be limiting when it comes to conservation efforts. Unless it is tested and tried on oceanic species or less abundant fish, the limitation of this technology may be in the species it is used on. ]]> 2019-03-03 19:30:58 UTC https://padlet.com/bailey92/cm0oznhe75l7/wish/337264111 Future Of AutoFish Predictions bailey92 https://padlet.com/bailey92/cm0oznhe75l7/wish/337264989  The future of AutoFish Systems looks bright as access becomes easier and agencies around North America use the tagging system to monitor hatcheries and stock fish all across the continent. 

In the future I would hope to see this technology either made larger or used on maybe sport fish such as trevally, tuna, and tarpon. These fish are facing increasing population crisis levels and so I feel like having such an efficient tagging and tracking system for more endangered fish species would be beneficial for conservation programs.  

Being portable the system has great potential and I wonder if as technology advances if the system could become smaller or even built into research boats so all you would have to do is park your boat on top or near a school of fish and you could mass tag the school right then and there. ]]> 2019-03-03 19:38:14 UTC https://padlet.com/bailey92/cm0oznhe75l7/wish/337264989 Works Cited bailey92 https://padlet.com/bailey92/cm0oznhe75l7/wish/337265884 AutoFish System - Northwest Marine Technology Inc.
