Mackerel

Countdown till the new event starts:

Mackerel (or Saury, 秋刀魚, さんま, Sanma) is an item that can be obtained during Mackerel seasonal mini-events. It is obtainable as a map drop, can be exchanged for various items, and is required for completing the event's limited quests. The events usually happen in October - November:
 * 2015 Mackerel Event: October 9th - October 30th.
 * 2016 Mackerel Event: October 21st - ?.

How to Obtain
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:


 * Overfishing reduces the drop rates, getting too many fishes within a specific time interval decreases the chances to obtain new fishes.
 * Each map may have an independent limit.
 * Special equipment can be used to increase the drops rates:
 * Sonars
 * Searchlight, Type 96 150cm Searchlight
 * Skilled Lookouts
 * Combo effects from equipping different pieces on one ship may exist.
