Mackerel will be REMOVED after the event. Be sure not to have any left by the end of the event.
Mackerel 068 useitem

Mackerel (Saury, 秋刀魚, さんま, Sanma, or "fish") is an item that can be obtained during Mackerel seasonal mini-events (based on Pacific saury festival). It is obtainable as a map drop, can be exchanged for various items, and is required for completing the events' limited quests. The events usually happen in October - November:

How to ObtainEdit

Known drop conditions:

  • Can be obtained only from specific map nodes. A notification will appear on a drop (see the gallery above).
  • Can drop only on A and S ranks, with a higher drop rate for S ranks.
  • Can drop even when you have no ship slots left.
  • Doesn't prevent normal ship drops. Also can drop without a ship drop.
  • You can't have more than 99 fishes at the same time during the event.

The following two mechanics are likely to affect the drop rates (note that the following info is partially speculative and wasn't properly tested[1]):

  • Overfishing reduces the drop rates, getting too many fishes within a specific time interval decreases the chances to obtain new fishes.
    • Each node, map and world may have an independent limit. Can be time-dependent.
    • For example, within a short period of time with a given equipment setup 1-5-I can drop 6 fishes at 40-80% rate, than 6 more fishes at 10-30%, after which the rate reduces to 0-20%. Possible countermeasures in this case: 1) farming other 1-5 nodes (F and G), other maps (e.g. 1-1), maps in other worlds (e.g. 3-3), 2) waiting on the node/map "morale".
  • Coastal Defense Ships can be used to increase effectiveness of drop chances.

Special Equipment for FishingEdit

  • Having the following Special equipment can be used to increase the drops rates of the Mackerel.
    • Combo effects from equipping different pieces of special equipment in one ship does exist, e.g. Searchlight + Sonar + Skilled Lookouts + Type 0 Recon Seaplane on one ship.
    • An official tweet hinted that using DepthCharge Depth Charges will cause Overfishing more quickly.

  1. The existence of overfishing and special equipment mechanics was confirmed in official tweets (TIPS-3, TIPS-4, and TIPS-5). The existence of the overfishing mechanic is easily noticeable (however, it's not so clear if there are separate limits for nodes, maps, worlds and how they interact). There is less certainty about special equipment and their effects, including combos, mostly it's based on tweet interpretations:
    • 海を照らす光源 - Searchlights
    • 魚群探知を支援できる装備 - Sonars
    • 少し乱暴な手法で海の中にどかーん! - Depth Charges
    • もっとスマートに暗闇でも魚群を捉える熟練のあの方々の活用 - Skilled Lookouts
    Then, one can question if both active and passive sonars work the same, etc.
