Here’s an example of an unsuccessful catch and release.
In North America, pickerel (often called walleye) are considered one of the best tasting fish. The typical size is 1-5 pounds, but if you are lucky, you’ll catch some over 10 pounds. If you are really lucky (not to mention skilled), you’ll get a beauty like this 14 pounder caught at Olive The Lake on the Marten River in Ontario.
The only way to accurately measure the length of a fish this size is to use a beer bottle.
