In all fairness the nets we were pulling that Tuesday were mid-lake, or as WH2 would say “the openness”. These areas, or at least in my experiences are typically inhabited by Wipers and Cats but I have caught a lot of Walleyes just west of where we were at which maybe gave me some false hope for the eyes. Lots and lots of 16”-18” wipers with the occasional 20” toads in the nets. Also had a good showing by the cats, they were ranging from 7”-21”. As far as numbers go it varies from net to net. That’s why the division sets so many nets all around the lake. Below is a copy paste from an email I received from Chris this morning. Note, these are preliminary numbers.
Trevor,
Saw a post from you on a BFT discussion regarding the Willard netting, and it reminded me to send you a quick note on how the rest of the survey went. Despite not seeing many walleye the first day, we saw plenty as we worked our way towards the north side of the lake on days 3 and 4 of netting. Walleye numbers still appear to be trending down, but not dramatically. For example, we had 28 walleye in the nets on day 3, demonstrating why we set so many nets, which is to reduce variability in our numbers and increase confidence in our estimates. Also, the young walleye I predicted did indeed show up, meaning our numbers should begin climbing again next year. Anyway, here’s some preliminary numbers and observations I sent to our managers after the netting.
Fall index netting at Willard Bay was conducted the week of October 13th. We set and emptied a total of 27 nets over a 4 day period. Preliminary results suggest the fishery continues to be strong. Wiper abundance continues to increase. Wiper catch per unit effort (CPUE) appears to be up about 50% from 2013 (29 versus 19 fish/net night), It’s worth noting that 2013 was the previous high wiper abundance for the decade, so observing another 50% increase in CPUE is a surprise, but a positive one at that. Plenty of young of the year (YOY) wiper were observed, suggesting good recruitment of stocked fish.
Walleye numbers are down, which we’ve been predicting for a few years now based on age and growth data. Despite this downward trend, CPUE may increase next year as we observed that YOY made up about 20% of the catch. Walleye YOY generally aren’t fully recruited/vulnerable to gill nets in their first year since they are slender and only about 8-10 inches long. When the YOY make up about 15-20% of the catch, in the past it has indicated the presence of a large year class of fish that will be present the next fall as 15-18" fish. This is encouraging and may indicate that supplemental stocking of 1,000,000 walleye fry this spring experienced some survival and recruitment. We’ll know more as our marking study gets underway next year.
Other fish. We continued to see plenty of catfish, young and old. Crappie appear down somewhat from last year, but numbers still appeared higher than what is typically observed.
Long story short - wipers numbers are looking great, walleye are down but expected to begin rebounding next year as this year’s recruits grow and become vulnerable to angling and netting.
Let me know if you have any questions.
Chris
