“Big Enough to Keep?”

DSCN1688

There is one thing about the culture of fishing, even the way society thinks about fishing, that I wish I could change. . . . The question about whether a fish is “big enough to keep?” is wrong, completely wrong, 180 degrees wrong. What?  You think my pointy-head has finally gone completely crazy? No, not at all.  Let me explain. . . . Catch and release is a part of modern sportfishing.  It is guaranteed that anglers will be releasing …

Walleye Spawn 2019

P4100061

I noted a couple of weeks ago that when spring rolls around I actually get outta the office and do a little field work.  Even though the water is cold and the weather can be more wintry than springy, I look forward to it every spring!  One of those activities is the annual collection of walleye eggs that our Nebraska fisheries staff does around the state.  Walleye eggs are collected and fertilized in order to produce the fish needed for …

Renovations

P9070092

Last week I had a boring blog post about fisheries science.  It was a fundamental description of what a “fishery” is and how pointy-headed biologists manage fisheries.  Part of the reason I posted that was because I wanted to lay some ground work for additional posts about other fisheries management topics.  So, let me reconvene the Fisheries Science 101 class again today and talk about a subject that I believe is misunderstood by some. . . renovations. Let me start …

What Lurks Beneath, Nov. 2018, and an Update

Fall2018Saugeye

Our Nebraska Game & Parks Commission fisheries biologists are finishing up their fall fish sampling around the state.  I am starting to hear a few stories about what they sampled, will be getting data summaries and starting to put together next year’s Fishing Forecast in the coming weeks. Once again let me post a disclaimer before I show you the pictures:  When pointy-headed fisheries biologists sample fish populations they are NOT trying to capture the biggest fish in a population.  …

Fisheries Science 101

DSCN3748

Ever since my days as a wide-eyed graduate student, I have known that folks, especially outdoors- and fisher-folks, have a great interest in what we do as fisheries biologists.  Early in my career I took every opportunity to communicate with people the work and projects I was participating in, and over the years my job has evolved into one where I do that all the time! However, it dawned on me last week that there are a lot of misconceptions, …

It is October and Fish Sampling is in the Air

FrameNetSet

Our Nebraska Game & Parks Commission fisheries professionals are always busy doing something.  Each season brings a different set of jobs and duties.  Autumn is when much of our fish population sampling is done, and our field biologists are on the water throughout the state right now.  Yes, that work goes on in the rain, sleet, snow, wind, whatever.  We do some sampling for species such as black bass and sunfish in the spring, and there are a few other …

What Lurks Beneath, June 2018

BOakFlattySpring2018

It has been awhile since I have teased you with photos of some of the big fish that our field biologists have had their hands on.  Time to change that. . . . We do a lot of our fish population sampling in the fall, but there is also some that is done in the spring and summer.  Again let me say that when pointy-headed fisheries biologists are sampling fish they are NOT just trying to catch the biggest ones, …

What Lurks Beneath, April 2018

IMG_1531 (3)

I mentioned that our Nebraska Game & Parks fisheries staff hits the ground running every spring and that we have really geared up with our collection of walleye eggs starting this week.  I also want to note that this sure ain’t the first field work we have been doing already this spring.  Our field crews have been on the water in several places sampling, tagging, collecting eggs, etc., etc.  I want to show you a few photos to give you …

What Lurks Beneath, Beautiful Flatties

IMG_1233

Last week I noted that Nebraska Game & Park Fisheries biologist are busy around the state doing fish sampling this time of year (“Survey Says”).  A couple of weeks ago I slipped out of the office for a day and got my hands fishy helping with some of that sampling.  I have blogged many times about the flathead catfish fishery at Branched Oak Reservoir and the research that has been done on those fish in recent years.  With a total …
