      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Keeping bigger fish can create giant fish???

Recommended Posts

Hammer Handle

This article says that fish can grow faster if smaller fish are kept, but keeping only the "big fish" can cause some to grow into giants.

I think the article says that we don't know anything yet....

Reading the story, it says the data was produced by a computer model. I am thinking that I will trust what is proven to be by the biologists that deal with the ecosystems on a daily basis versus a machine that will not function in water up to its knees. It sounds like a bs story with results that had to be published to get paid for doing a study.

It sounds plausible until you start to factor in fishing pressure. The big ones are usually the most vulnerable, so they don't last long when fishing pressure is applied.

Very interesting thought. I have to believe each system is different and a lot of different factors will effect the outcome. Definately something to consider.

Bigger panfish do eat different things than smaller panfish so there is one point. But you will kill the genes in the fish. What happens when those few trophys die? The young of the trophy fish will automatically become stunted as there are only small fish left. What you do is just control the overall population. That happens by having big predatory fish in the lake. They will weed out the weeker fish and keep only the strongest panfish.

Umm cannibals...giant fish eats big fish, big fish eats little fish.

Take big fish out of equation

Giant fish eats what? little fish...Ecosystem change/crash.... crazy.gif

The logic just seems very flawed.

If you catch and keep the big fish what will be left to grow into giant fish?

There might be one or two elusive big fish that people couldn't catch which will probably grow into giants but they got that way becuase they couldn't be caught so from a fishermans perspective why would I want to manage a lake so that it maintains a very small population of giant fish that no one is able to catch?

I think the accepted method of releasing the bigger fish is working just fine and will continue to keep working.

I think whats best is a balanced population of fish in all year classes and sizes.

Most likely, there's a reason that the research in question was not published in a well-respected, peer-reviewed fisheries science journal. Rather, it was published in a very broad-brush journal with a less notable track record than many of the more mainstream fisheries biology publications.

Along with questions regarding modeling vs. sampling real populations, some of the major concerns I have are:

1. Interactive effects amongst different game species - i.e. predator/prey relationships - Cannibalistic or not

2. Assumption that fishing pressure, size structure, and environmental variables hold constant

3. Long-term sustainability of this approach

It seems to me that this flies in the face of years of fisheries research regarding selective harvest, fishing opportunity, and pressure. In other words, it's far too soon to suggest that harvesting large fish help what's left become giant; especially when based on an untested artificial sample.

I dont think that they are saying that the overall fishery will have big fish, but that there will be a handful of fish that will be much larger than what is in a typical lake.

I saw an example of this growing up in Eden Prairie. We caught a ton of very small fish from Round Lake (which is about 30 acres, just under one mile around). They killed it off 2-3 times and there would be HUGE fish in there each time it was killed off. We would also stumble into schools of 1lb+ sunnies where the rest were tiny. It was extremely rare to catch a "regular" size fish, they were huge or stunted.

Computer generated Mother Nature confused.gif Heres a abstract of a study that shows how that theoretical computerized management system fails

Source: Blackwell Synergy

Populations where large fish were selectively harvested (as in most fisheries) displayed substantial declines in fecundity, egg volume, larval size at hatch, larval viability, larval growth rates, food consumption rate and conversion efficiency, vertebral number, and willingness to forage. These genetically based changes in numerous traits generally reduce the capacity for population recovery.

It is intersting to try and theories fish size managemnet. We can guess and dream that wecan do things to produce trophies for us to catch. But genetics, lake classification, weather, overall fish population, development, and fishing pressure all have an effect on the lakes. We have lakes that will never grow trophies and lakes that consistently do. I wonder more of why must we produce trophies to catch. If that is your sole purpose of fishing you may be missing the boat. And we wonder why we are not recruiting as many young fishermen/girls.

      The wife and I were up to L O W  for whole week. Great weather, good fishing and fun time. Was able to fish 7 days split up between Morris point, Long point and the river. For me Long point was the better bite. May have seen a couple members of outdoors Mn on Tuesday out of LP. Let me know if I'm right. Also met member from Wisc. at Morris point( real good guy) Anyway didn't seem to matter much what color jig caught them on every color with frozen shiner. Some days were better then others but always caught fish. Ate several meals of fish and brought fish home. Also caught a 14 in perch that I brought into taxidermist. Plan on going back at least one more time this fall . ( Too good not to).

      That the best sounding plan yet!! same to you and your party.

      Got some grouse and saw some nice coveys. The biggest was 6 birds but found couple groups of 5. That is always fun.
    • eyeguy 54
      we mainly jigged fatheads in front of their mouths. 2 weeks ago also and tried a few different times over 3 days this trip. water is still crazy low so I don't think many boats will be using access. Also tried a couple different plastics and some gulp. Probably ready to go crazy up there soon.  Last year at this time it was really good. Might get there once more before ice time but not sure.

      Been thinking about breaking out the Jiggin Raps, might have to give that a shot. It's been too crowded out there this weekend with MEA going on.

      Sounds good! May an oversized deer with obscenely large antlers find its way to you!  
    • DLD24
      Well the weather was pretty crappy but the fish were biting...Had to sort through but kept some for dinner. Caught a variety today, eyes,jumbos,crappie and a few smallies... rigging on or next to rocks worked best for us.
    • ANYFISH2
      hummm, hadn't heard a thing?
    • ANYFISH2
      Good luck. Maybe we will see you Friday. I will let you know how things are looking by us as the weekend goes by.
