Submitted by admin on Sat, 2011-07-23 22:46 TU encourages trout and salmon anglers to voluntarily practice catch and release because of its proven benefits to trout and salmon populations. TU, and its local chapters and state councils, often do advocate catch and release regulations where they are appropriate. Typically, catch and release regulations are most useful on streams and rivers where there are highly valuable populations that are facing heavy fishing pressure. Curtailing harvest in these situations can help increase and sustain trout and salmon populations, and has done so in most situations where catch and release has been used. Question What does catch and release mean? Why is it important?
