Mahkra Fishpacking consists of a large factory on the most northern shore of the Commonwealth. The exterior is fortified with a stone wall and sandbags. During the first visit, the courtyard, catwalks, and interior are littered with the bodies of the former raider owners. Apart from the main entrance doors to the front, there is also an unlocked hatch entrance in the northeast corner of the roof, accessed by an exterior metal stairway.
The upper level of the factory initially contains no hostiles, but once the lower level is explored, a number of synths will enter the building, which then spread throughout the entire facility (even after clearing the lower level). A number of synths will also be outside of the facility and on the roof upon exiting the plant.
To the northwest is a feral ghoul stuck on a platform on the water.
- Robot model kit parts - On the eastern exterior of the building behind an advanced locked door on a shelf.
- Bottle message #5 - Outside the plant, follow the east side path to the water, there is a rowboat and the bottle is upright in the sand nearby. The bottle objective leads to an underwater skeleton in a tub.
- Fusion core - Inside a hideout beneath the bridge leading to the factory.
- Vault-Tec lunchbox, also in the same hideout (medium level radiation) under the bridge. Behind a Novice locked cell to the right on a shelf.
- Mahkra facilities key - On a dead raider hanging out of a storage bunker at the right side of the plant. Unlocks the security gate and a door.
- Tesla Science Magazine issue #4 - Back basement area, northwest corner, underneath the stairway leading to the chained door. Found next to an Expert locked safe and a dead raider.
- Nuka-Cola Quantum - Back of the blue trailer in the middle of the factory when first entering. It is in a crate next to a dead raider, booby trapped with a frag mine on the floor.
- Mahkra facilities key - On a dead raider in the southeast corner of the lower floor, next to an Advanced locked security gate. Unlocks the nearby security gate and an exterior door on the east side of the facility.
- A total of 84 trays can be found in the lower level of the facility, resulting in 84 aluminum when scrapped.
- If allied with the Institute, the synths will simply greet the Sole Survivor and will also destroy the protectron if activated.
- This is an excellent area to gather aluminum. There are over 80 trays on the conveyor belts in the lower back basement that can be salvaged for 1 aluminum each. These will respawn after a period of time.
- There are fish on the conveyor belts on the lower level that are in reasonable condition despite them being there for over 210 years.
- When traveling with Codsworth here, he states that his sensors detect an unpleasant odor. Danse and Deacon also comment on the foul smell, as does Ada if Automatron is installed. X6-88 proposes finding a way to weaponize the odor. This presumably is the old stock on the shelves and fish on the conveyor, however, after more than 210 years, the fish should have decomposed entirely.
Mahkra Fishpacking only appears in Fallout 4.
- PC Playstation 4 Xbox One The Sole Survivor can get stuck on top of one of the conveyor belts in the basement with the dinner trays on them, forcing to load a previous save. If player character has a companion that is wearing power armor when this bug occurs, simply select them with the cursor and interact with them as if one was attempting to enter their power armor. This will teleport them to the location directly behind the companion's armor. The reason for getting stuck is because the player character is between rails that are squeezing them in, look up and follow them out. One can also sit in the nearby chair or stool to get unstuck.

- PC Xbox One Many items may not re-spawn inside (mainly the trays in the basement). This can occur if all synths are not eliminated. [verified]
