EMPORIA – Many advances in technology arise out of a desire to improve output and efficiency, and the fishing industry is no exception. One such advancement that has many anglers “picking sides” is the introduction, and proliferation, of live-imaging sonar (LIS) – sonar that allows anglers to view fish and structure, below and around their vessel, in real time and often with great clarity. While some believe LIS adds immense value to the overall fishing experience, others believe it poses an ethical dilemma, blurring the lines of “fair chase.” So, when is an advancement too advanced? That’s the data KDWP Fisheries staff sought but couldn’t find; so, they developed it themselves in a first-of-its-kind study.
