First, check the Day Combat page for the Opening Anti-Submarine Attack. If any of your ships besides Isuzu meet the 100 ASW requirement with equipment, then use them. (Isuzu of course already has the attack).

I'd try and craft some more Type 3 Sonars and some Type 3 Depth Charges if you can. Every little bit helps.
