PIT tags and Passive Antenna Systems- PART 1: A Sunpass for Sunfish.

Hi folks!

            Whether you’re a fisherman or a scientist one of the most simple and common questions while out on the water is: Where are the fish?  Well, in order to answer that we need to understand fish movement patterns along with the how, when and why fish will be in a given area.  In this 2-part post I will discuss tracking fish movement with PIT tags & passive antenna systems and my experience applying this technology across environmental extremes to both the Everglades marsh and arctic tundra river systems. 
            Recent technological advances have seen a boom in different movement tracking devices available to fisheries scientists.  Acoustics, radio telemetry, and satellite tags have provided a wealth of previously unattainable information but have species specific size restrictions and are often too expensive for the budget of many researchers.  In these cases, PIT tags and their associated passive antenna systems provide a cost effective way for the researcher to study the movements and habitat use of fish both large and small.

So, is this “Fishing App” Worth it or not? (Author: Ryan Jiorle)

Fisheries science is a field whose very foundation (“counting the fish in the ocean”) creates doubt in many anglers' minds.  Using smartphones to have recreational anglers upload their fishing information creates doubts in just about everyone’s minds—fisheries scientists included.  However, that has not stopped a few groups from steaming forward under the belief that something created by and for anglers will cause them to report honestly and faithfully.  The most extensive program to date is the Snook and Gamefish Foundation’s (SGF) iAngler app, the flagship app under its Angler Action Program1.  Originally started as a way to provide state scientists with more data on snook fishing in Florida, it has expanded to include fresh- and saltwater fish across the country, inevitably turning some heads around the fisheries community.

University of Florida MS student Ryan Jiorle is a Fish Detective!

Ryan recently took a trip to Ireland to do ecological research at the Lough Hyne Marine Nature Reserve. Watch the video he made describing his project! We've also included some text from him further describing his work.
