Rush

""Orange S2. That explains why the Salmonids are restless. If you start glowing...well, good luck.""

- Mr. Grizz when a Rush wave starts

Rush is a Known Occurrence in Salmon Run.

Description
During Rush, Glowflies will surround one player at a time at random, causing all Salmonids to focus on that player. The only Lesser Salmonids that spawn are the Chum, which run towards Glowflies in a frenzy. These chum have red eyes and swarm in much larger numbers than the Chum found in regular waves. Goldies are the only Boss Salmonids to appear, which will behave the same as the Chum, running in the same crowd. When splatted they drop three Golden Eggs total, which will spread out farther than usual, making it harder to collect them safely. The Salmonid crowd will swarm towards the player with Glowflies without attacking them or other players, moving with greatly increased speed; they cannot be distracted, and will eventually jump up towards players hiding in walls.

Snatchers may spawn to take unattended Golden Eggs, though they are not affected by the presence of Glowflies and behave as they do in standard waves.

This event can only be experienced if every player in the group is at least Part Timer, and cannot occur during low tide. The maximum number of enemies that can appear on the map ranges from 19 to 32 based on the difficulty level, where Chums spawn every 10 frames between Part Timer to Overachiever and past Profreshional 100, with Profreshional 0 - 99 having it decreased to 5 frames. Goldies appear on every 20th spawn.

Salmonid Field Guide
The following text is quoted from the Salmonid Field Guide.
 * What Happens
 * Large groups of ferocious Salmonids appear and carry out rush attacks at furious speed.
 * These crazed Salmonids gather in response to the appearance of Glowflies.
 * How to Get Golden Eggs
 * Take out the Goldie hidden in the school of Salmonids.
 * Advice from Mr. Grizz
 * Stand your ground with your allies and concentrate your fire on the incoming Salmonids!
 * Watch out for the Glowflies—if they buzz around you, a concentrated attack won't be far behind.
 * Supplementary Information
 * It is claimed that the Salmonids' increased aggression is tied somehow to gravitational shifts due to the planet's celestial course, but there is still much that is unclear.
 * It is said that in pre-medieval times, before effective defense measures such as long-range ink attacks were available, many cities fell before the rage of the Salmonid rush.

Tips

 * The player being targeted should try to funnel the Salmonids into a choke point to help their team dispatch them faster.
 * Non-targeted players should prioritize the targeted player's safety. The safest time to deposit Eggs is when the source of the stream of Salmonids shifts.
 * There is no reason for the crew to separate during this event. Stick together near the Egg basket.
 * It is advised to pay attention to whenever a coworker is down and revive them as soon as possible.
 * Unless it is absolutely necessary, do not collect Golden Eggs if you are targeted by Glowflies. It is advised to stay in a safe spot and attack from there as the Salmonids move very quickly.
 * It is possible to cling to a tall wall to stall the Salmonid rush, giving time for teammates to safely carry and deposit Golden Eggs. If the targeted player stalls for too long via this method, the Salmonids will start to jump to attack the targeted player, therefore it is recommended to cling to a wall that has a platform above within reach as the Salmonids gather below, but only for short intervals.
 * Another reason to not stay swimming on the wall is there a glitch that allows the Goldie's eggs to be released inside the wall, rendering them unobtainable. This only happens if a Goldie is up against a wall.
 * All Rollers are able to crush the Rushing Salmonid crowd while rolling. The deals the most damage with an output of 400, making it easier to crush Goldies, which have 500 HP. The  deals considerably less damage while rolling, and can cause players to be bounced back mid-roll, so it's more advantageous to flick towards the crowd when wielding it. All other Rollers will crush Salmonids mid-roll regardless of their speed, and consume less ink the slower a player moves while rolling, making it more favored to roll forward as slowly as possible or even stay static with the Roller out forward.
 * Inkbrushes and Octobrushes do not have this ability.
 * When using a brella, it is advised to use the released shield mechanic to take out a long line of enemies at once, similar to the Rollers. is the most effective for this, as it will be able to squash 72 enemies in one go.
 * Chargers are able to use their piercing mechanic to take out long lines of enemies.
 * Blasters' bursts can be used to kill multiple Salmonids at once via aiming at the side of the stream, rather than the front of it.
 * If you are targeted in Ruins of Ark Polaris, avoid jumping onto a ride rail unless you and your team are struggling to survive: the stream of Salmonids will rapidly circle around the Egg basket as they follow you, ending on your landing point, effectively putting both your coworkers near the basket and yourself in extreme danger. Instead, focus on generating a choke point with your team and only jump onto the rails if it is a matter of survival.
 * Note that Special weapons cannot be activated on the rails, making it a very risky last resort if two or more coworkers are down. Activating Specials such as the Inkjet, Splashdown or Bomb Launcher is more advantageous than hopping onto a rail.
 * In Spawning Grounds, gather the crew around the Egg Basket and have the teammate attracting the Glowflies stay above the ramp. This makes it easy to protect that teammate, while the rest of the crew collects Golden Eggs.
 * Players can also stick to walls to potentially redirect the rush, though sometimes the rush may approach from above,
 * In Gone Fission Hydroplant, targeted players can stick to the walls. This is generally safer than standing on the ground, and salmonids will move below the tagged players, providing easy targets for other players standing above. A good place to do this is the grated bridge north of the egg basket. Another effective position is a ramp south-west of the egg basket. It has only one way which Salmonids can take to come to the crew, making them easy to control and splat, it's located relatively close to the basket, so even if throwing eggs isn't possible, one of the crewmates can collect and bring them to the basket directly, and it's possible to stall the rush by jumping back and forth between the nearest ramp.
 * At Sockeye Station, the targeted player climbing up or down the central tower through the grate can help to redirect the rush so that teammates can focus on defeating enemies and tossing Golden Eggs into the basket.
