Hey there, fellow finned explorers! I'm Erik Njordson, your go-to guy for everything fishing and fishy. Born in the beautiful fjords of Bergen, Norway, I was practically raised with a fishing rod in one hand and a net in the other. When I was 10, my family and I migrated to the rugged coasts of British Columbia, Canada, where my love for fishing took on a whole new dimension.

I hold a degree in Marine Biology, which means I can talk fish—scientifically. My writing? Imagine your favorite fishing buddy and your Marine Biology professor had a baby—that's me! Informative but never boring.

When I'm not busy casting lines or jotting down the secrets of the deep, you'll find me hiking through the stunning Canadian landscapes, snapping photos of wildlife, or in my kitchen. I love cooking up a storm, especially when the main ingredient is my latest catch, prepared using recipes passed down from my Norwegian ancestors.

I'm fluent in both Norwegian and English, so I bring a unique, global flavor to the angling community. But remember, fishing isn't just about the thrill of the catch for me. It's about respecting our aquatic friends and their habitats. I'm a strong advocate for sustainable fishing, and I hope to inspire you to be one too.
