Blackpool failed to muster a shot on target but claimed derby day bragging rights in the cruellest fashion.
Nathan Pond's own goal consigned Town to defeat on their first ever Football League visit to Bloomfield Road
Fleetwood made the brighter start, roared on by 2,000 fans.
And they very nearly took the lead, a goal-line block denying Joe Davis his first for the club, David Henen picked up the loose ball and tried to curl it under the bar from 18 yards out, Dean Lyness with a smart save to deny the Everton loanee.
The visitors were happy taking the game to Blackpool but were occasionally guilty of over-committing,
It allowed Blackpool an outlet, Bright Samuel lively down the left.
Dealing with the break Town weren't the composed unit they have been in recent weeks.
And when Brad Potts found space down the Blackpool right they were caught napping.
The cross had some zip to it, Pond stretching a leg and turning past his own keeper, Blackpool handed something to cling onto.
It proved a frustrating time for Town who might have fallen further behind within sight of the break.
Amari'i Bell got mixed up with Pond, a Keystone Cops clearance handing it to Jack Redshaw who somehow blazed over from six yards.
Fleetwood turned up the pressure after the break but struggled to carve out clear chances.
Even so, Henen very nearly hauled them level, set free by Fosu, he let fly from a tight angle, the ball smashing the woodwork and rolling clear.
In strong winds, on a greasy pitch Fleetwood seemed uncomfortable crossing, shooting from range or walking the ball into a crowded area.
The introduction of Bobby Grant and Nick Haughton gave Fleetwood different outlets - the latter almost providing a stunning late equaliser, playing a one two with Sarcevic and stinging the palms of Lyness.
That proved Fleetwood's best chance, Blackpool digging in, determined, to claim the points.
