Perch die off? or kill

[bullseye6]

hey tubedude,you seem like u are really knowledgeable about this fishing game.u always seem to have good answers and solutions to alot of quistions on this board.i hardly ever post but read on a regular basis.and really enjoy the group of people on bft who are willing to give valuable info and share ther knowledge with everyone.i guess i need to get in on the fun.any how i remember reading an article on this topic in the past about yellow perch die offs up north and they said it was a natural occurence in all lakes.but there were alot of factors involving how much u would really notice the die off.1 factor i remember was food availability(a major factor)small fry feed on algea and plancton,bigger fish feed on fry,and large fish feed on them.something that all of us already no of course.but here is the prob with drought conditions,waters come up in spring from run off fish spawn in the shallows,water is drained or used and drops before the hatch do to low lake conditions already.resulting in no small fry for larger fish to feed on.this is a factor that starts kind of a domino afect.the sey that it takes 4 years of normal fry hatch to make up for one bad hatch.and bring the food cycle back to normal.for example when the perch die off happens it is usually the larger that die but u wont notice a real impact because u still have the fish that are from the previous years hatches.so one year with eggs left high and dry , let alone several years of high and dry bad hatches here in utah,when the die of does happen it pretty much wipes them out for years because ther is no youger fish to replace them.drought is oviously a major factor for our perch problem here in utah.i think we have all been spoiled from the last three years at rock port and thought and never really thoght about what was comming.well here we are....just like pineview.pineview has been at terrible low water levels for the last few years.several dry hatches.bass, crappie,perch all have taken a turn in a bad way there.no hatches,no foooood.also when water levels are below the weeds and forage ther is alot less algea and plankton for the fry that do hatch to feed on and also alot less oxigen.oh well i could go on and on but i really suck at typing and my fingers are cramping up from typing in an hour what most people can do in 5 minutes. anyways good fishing everyone........
