According to NCWRC research since the introduction of blueback and alewife herring into Lake James, walleye reproduction has declined.


Stocked fish have made up 70% of class zero and 100% of class one fish in 2013 according to NCWRC surveys.


Looks like a lake , that until recently, had excellent natural walleye reproduction will now have to be stocked, adding extra costs on the wildlife department.

Do you have a link to the article? I couldn't find it on google. Also what is the definition of Class? I assume it's the year it was stocked.

Thanks!

What is the connection between decline in Walleye breeding and blueback herring? Do the herring not live at depths the walleye inhabit most of the year?

See page 15 of this document for the summary

Stocked fish were marked with oxytetracycline (OTC) to measure percent contribution of age-0 and age-1 stocked Walleyes to the overall fishery. Survey results from 2012−2013 showed 70% of age-0 and 100% of age-1 Walleyes were from stocking efforts, which is much higher than the established 25% success criterion

hmmm, nice post gambrusia,just read a bunch of the reports, i bet it is hard for the ncwfc to keep up with peoples basic disrespect for laws / restrictions on bait and rouge stocking to suit there interests rather than the health of the natural ecosystem of the body of water they are fishing. this day in age where most peoples favorite words are ... me,i,my , and mine just dont care about anything but what they are doing at that exact point in time to suit them, is there a answer? or is the time when people respected others and the rules and regulations a part of history

Once herring are in the lake, they are not coming out.

I wonder how much stocking 30,000 walleye costs?

 

[vaporizor]

how where the herring introduced? by someone bringing them there for bait and dumping the rest out that were unused after a day of fishing?

 

[ozarks transplant]

how'd the herring get there? maybe somebody was trying to cut down the mightiest tree in the forest ...
