The Houston was envolved in a surface engagement at the start of the war and I fail to see what that has to do with sinking a submarine by air at night. Another very important variable is the pilot. By mid 1943 the Japanese were hurting for trained pilots. They could ill afford experienced combat pilots for the ASW because they didnt have enough to man the carriers!
True Fluckey ran into a japanese plane with radar. The plane missed because japanese radar is not very good. Fluckey also for the most part operated surfaced unless he was resting, evading radar warnings, or making a torpedo attack on a warwship.

The same can be said for Japanese radios installed in aircraft too.
Now add SD and later SV radar on US boats and you pretty much come up with hampering Japenese airpower even more.
BTW. Only 5 US subs were lost to air attack alone. In combination with surface asw the total reaches 10.

Also this page pretty much sums up Japanese ASW:

Japanese ASW was poor and at best mediocre.
