Releasing big sunfish helps protect against stunted population

 :coffee: .....
Minnesota anglers harvest around 16 million sunfish each year, making them the state's most harvested fish. To protect big sunfish and avoid stunted populations of sunfish, the Minnesota Department of Natural Resources is encouraging anglers to release large sunfish, and keep smaller fish for eating.

   :fishing:

:Fish: :Fish:

Sunfish spawn in large nesting colonies during the spring and early summer. Parental male sunfish build and defend nests. Females will select a male, lay eggs, and leave them for the male to protect and fan with his fins. These nest-building male sunfish play an important role in repopulation with the largest sunfish often getting the best spawning sites.

 
 :popcorn: ...
When anglers keep only the largest sunfish, which are usually males guarding nests, the remaining small males don�t need to compete with larger males to spawn. Instead of growing, they devote their energy to spawning at younger ages and smaller sizes.

 
 :tut: ....
Spawning sunfish are particularly prone to over harvest because they are very aggressive while defending a nest. Anglers can help by releasing spawning sunfish, especially large, nesting males. Released fish have a high survival rate and will typically return to their nests to complete the spawning cycle.

Minnesota angler attitude surveys between 1987 and 2017 found that anglers were generally satisfied with the number of sunfish they caught, but were often dissatisfied with fish size.
To maintain a high quality fishery, it'ss important that anglers, guides and resort owners, all understand the important role these large nesting fish play, and that we all work together to exercise a conservation ethic that ensures these fish thrive, said Grand Rapids area fisheries supervisor Dave Weitzel.

Protecting larger spawning sunfish is supported by a study of the Fuller Tackle Contest in the Park Rapids area. The study found that until 1953, mean weight of entered bluegills fluctuated around 1.3 pounds; after 1953, mean weight declined. The change in fish weight coincides well with the 1954 regulation change that allowed for year around sunfish angling, and no longer protected the spawning season.

Since the 1954 regulation change, sunfish numbers have generally increased in DNR lake surveys, suggesting an overall increase in sunfish densities - a trend often linked to a decline in size

Yep I agree on sunfish and all fish in general.  When our family came here from Germany back in 58,  My brother and I went fishing with my dad every weekend in lakes around Duluth and we kept everything.  The bigger the fish, the better it was.  Over time that changed, probably in the mid 70's.  That's when I threw my first 6 pound walleye back.  It was so hard to do, but after the release the next one was so easy.  Haven't kept a large fish since.

This is about the future of fishing.  We can follow the regs, but make our own regs also about how many we keep of any species and what size is the limit as far as keeping per species.  good luck.

I mostly agree but I will add that if you really want to protect them then don't fish them on their beds. Also, I think a lot of people would be surprised how many released fish don't survive. If you are going to release them don't even take them out of the water.

depends on water temp. They spawn after crappies do. There usually done by mid June. However I've caught them in July with spawn in them. They get released. Done say they spawn twice bit I don't believe it.

Heard that too, glenn. I think they might some years.  :scratch: Didn't figure glenn would need to worry 'bout this 'cause we all know he only catches little ones.  ;) :laugh: :nerd: :evil:
