Cool off is not worked.
You need to switch to other map before start to farm the overfishing map again. 1-6 drop a significantly number. So go there before go to World 3 again?

Also if you got more than 1 skilled lookout it will be helpful.
Use on DDs with Searchlight-Skilled lookout-Sonar combo
Within 20 tries got 2-4 fishes already.

i already have 29 fish, just 1 more to go

most of my fish from 3-3 and 1-1
*(and 1-5 as well)
last week use 1-1 to clear the 36/24/12/6 quest

for anyone who interest my 3-3 setup:

i do not use the bomb / depth charge...
only DE, recon plane零式水上偵察機, swordfish, searchlight, sonar, man toilet熟練見張員

for the DE, i only found 1 shushushu at 3-3 boss

Any understand the ship lock of this event? Does all ship from E1,e2,e3 can join batttle in e4?
or 「西村艦隊（遊撃部隊）」ルート got special rule cant use lock ship from e1,e2,e3?

I just clear saratoga quest... this is my 5-5 attemp:



this screenshot is A rank...
for the S rank, i put abukuma 2nd place, zuikaku 3rd, shoukaku 4th, asashio 5th, akizuki last...

use new formation for all the nodes before boss, and pray hard that go to the boss node and asashio not orange /red before the sub die

and my this S rank is first kill of the boss... if last kill, don't use jet
*sorry, my mistake last kill no jet is for 6-5
take me a few run to get S rank... i think the new formation, the last dd will be aim most by enemies, my asashio keep on get half / red hp before reach boss node, until i swap the position...
BTW, i do not have enough screw to make all the night battle planes
so i guess i ask my saratoga to wear black dress instead

see if this setup can help you

well, it is up to u

tbh, i have quite a lot of fail run for this attemp

for the chance to reach boss, can only pray hard...

i not too sure, but i think can use 2CV 1BB or 1CV 2BB...
not sure is it need 2 CV or not...
