“It’s not the young ones that should be thrown back, but the larger, older fish that should be spared. Not only do the older fish provide stabilityto the population, they provide more and better quality offspring.”
Can a fish be too big to keep?
This is a basic principle in fishery management. Accordingly, professional fishers and recreational anglers have to release any fish they catch that is smaller than the minimum size stipulated in many fisheries regulations; only the big ones they are allowed to retain.
Should you release big fish?
Releasing large fish is essential to the health of any fishery. Only a small percentage of fish reach spawning size (1 in 10,000). Large fish pass on healthy physical traits and survival instincts to thousands of young. Large female walleye lay about 26,000 eggs per pound of body weight each season.
Why do people throw back big fish?
Many people do it for a stress release. Some do it to see how large a catch you can get, then toss it back in so the fish can keep growing and living.
Why do fish have to be a certain size to keep?

Catch and release fishing improves native fish populations by allowing more fish to remain and reproduce in the ecosystem.In catch and release fishing anglers immediately release native fish – unharmed – back to the water where they are caught.

Like seatrout, hook position affected survival rates; more than 50% of the throat or gut hooked fish died. These studies demonstrate that catch-and-release-fishing works-most fish that are released survive. By following a few simple guidelines, anglers can maximize survival rates.
Does throwing fish back hurt?
Unfortunately, people who practice “catch and release” cause no less harm to fish than do other anglers. Fish who are caught and then returned to the water suffer such severe physiological stress that they often die of shock, or their injuries may make them easy targets for predators.

10″-12″ are perfect keepers, and never more than I can eat that day. Walleyes over 20″ go back no matter where I’m fishing in MN/WI, and saugers over 18″ go back as well. I find that walleyes and saugers under those sizes are usually males, which I generally think is a good thing as well.
Why do you throw back small fish?

The fish will try to run away from danger at any given point. I see this often when trying to catch a fish in the aquarium shop. Some will try to jump out of the aquarium. If the fish are big they will have very little space to make a sudden turn and in this process hit the glass violently.

- Bettas.
- Plecostomus.
- Discus.
- Swordtail.
- Pearl Gourami.
- Zebra Danios.

Shortened Life Span
A juvenile fish growing up in a too-small tank can be expected to experience stunted growth, spinal deformities, atrophied muscles and other developmental heath problems. As a result, a stunted fish’s life span is significantly shortened, too.
