The Big One Deep Lake Visual Guide: Yellow Perch, Whitefish, and Kokanee Salmon

If you're unsure what to catch in Deep Lake, try choosing three distinct illustrations before chasing legendary fish. Yellow Perch, Whitefish, and Kokanee Salmon inhabit the same fishing spot, but their distinct appearances and Fishpedia activity time descriptions make them great candidates for dividing your collection goals.

As a developer building The Big One, I'm introducing these three fish based on current game data and official species illustrations. This is an in-game collection guide rather than a biological ecology guide, and it is not an announcement of a new update or a specific store version release.
Yellow Perch to Look for During the Day
Yellow Perch is classified as a common species in the current data. Its Fishpedia description notes that it is especially active during the day and responds well to small fish bait.
Remember the body color and patterns shown in the illustration first, and cross-check the name in the Fishpedia. This will help reduce confusion with other species sharing a similar silhouette. Bait descriptions serve as clues for your choices, not a guarantee that it will be hooked on your next cast.
Whitefish, Another Daytime Contender
Whitefish is a high-grade species, and its Fishpedia description notes daytime activity and responsiveness to basic bait. While exploring the same time of day as Yellow Perch, you can target a different illustration and name for your collection.
If you're using basic bait, check the Fishpedia description and continue fishing. You don't need to assume that buying a specific new bait is required to encounter Whitefish. However, you cannot calculate exact probabilities per bait purely from the brief Fishpedia description.
Kokanee Salmon, Evoking the Dawn
Kokanee Salmon is also a high-grade species, but the time highlighted in its description is dawn. Read alongside the note that it consistently responds to basic bait, it gives you an observation target distinct from the two daytime species.
Here, dawn refers to the time period displayed on the game screen and in the Fishpedia. Do not conclude from this article alone that you need to set a real-world alarm or log in at a specific hour. It is best to check the conditions and descriptions shown directly during gameplay.
Turning Three Illustrations into a Collection List
Look up the three names in your Fishpedia to see if you have records of catching them yourself. Viewing an entry's information is separate from having a catch record, so setting a single species you haven't caught yet as your goal for this visit simplifies your decision.
After fishing, take a brief note of whether you caught it and which time period to check next. Instead of judging rarity or odds based on three attempts or a single short session, simply use the Fishpedia description as a starting point for your next choice.
Carrying Over to the Next Cast
The illustrations in this article are visual aids to help remember Fishpedia names and are not scale diagrams comparing actual sizes. Please check your current playing version for gear, unlock status, and on-screen guides.
If you haven't started playing The Big One yet, you can check out the game in the store below. If you're already playing, pick one of the three Deep Lake species you haven't caught yourself yet today.
