Destiny 2: Season of the Deep is water-themed, and one of its most notable additions is a very unexpected one: fishing. Yes, the long-running looter-shooter is now home to a full-on fishing minigame, and while you shouldn't expect anything that compares with the in-depth mechanics of a proper fishing game, it does make for a fun distraction. And there are some layers of complexity, such as bait, a Focused Fishing meter, and shifting locations of fishing ponds to account for, which we break down below. Fishing is also a key component of a new secret Exotic quest.
To fish, you simply stand on the dock and hold your Interact button/key to cast a line into the water. When a fish eventually grabs on, you'll see your lure go under the water and a message will appear. Press Interact again--ideally the instant the message pops up in order to secure a "perfect catch." Even if you don't time that correctly, you can still reel in your catch, though wait too long and you'll get nothing.
Be sure to actually pick up the fish you catch--they'll be laying on the ground around you, and you'll need to walk over them to collect them. (Sadly, the Shoot to Loot perk won't grab them for you.) Fish can have different weights, with larger ones (those 18kg and above) progressing a particular Triumph, We're Gonna Need a Bigger Tank. Catching fish more generally will also contribute toward a Week 1 seasonal challenge, The One That Didn't Get Away.
Although there is a marker on the map for each destination, this won't guide you to the exact location of a fishing pond, assuming there is one currently available. Instead, you'll need to explore the area to find one:
On the EDZ, somewhere along the southern coast of the OutskirtsOn Nessus, in the Radiolarian fluid in The Cistern, east of the Well of FlameOn the Throne World, on the northern coast of MiasmaFortunately, there is a relatively easy way to spot these fishing ponds: Look for a beam of light being emitted into the sky. You should be able to see this from a fair distance away, signaling the presence of a fishing pond on the ground below it.
You can hold a maximum of 500 bait at a time. Bait is earned from completing various activities--the new Salvage and Deep Dive modes, for instance, as well as patrols, public events, and playlist activities like Crucible and Gambit--or by collecting destination materials.
By catching legendary or Exotic fish, this meter will increase. All nearby players' catches will contribute to your meter, even if they aren't in your fireteam. This means you ideally want to be fishing at a pond with multiple other players, and you'll want to do so for as long as possible, as the meter will reset when the pond despawns, even if you don't leave the destination and wait for another pond to appear. You don't have to be present the entire time to benefit from Focused Fishing, as the buff is tied to that fishing location.
Reaching each of the increments will boost your chances of rarer fish, and you'll see messages like, "Nearby fish have begun to take notice" to denote your progress.
At any time, you can head to the nearly opened wing of the HELM to release your fish into the aquarium, which is done with a hilarious, Gambit-dunk-style flourish. This is how you receive rewards for your time spent fishing, as depositing fish will get you glimmer, Sonar Station reputation, and--in the case of legendary or Exotic fish--actual weapons and items, including the new Just in Case legendary sword.
Fish you deposit will then appear in the aquarium, alongside various other themed items from the game's past. There are numerous Triumphs to complete related to fishing, with some unlocking additional decorations for your aquarium.
