ADS-B is Automatic Dependent Surveillance Broadcast-out and it's not radar, but a 1.09 Ghz signal that sends out some information about the aircraft.
There is ADS-B "IN" as well, which allows you to receive the broadcasts, which is what Ino is using. And there are devices that do both, send aircraft data (OUT) and receive data from other aircraft (IN).
Since the garmin unit costs $4,000 https://buy.garmin.com/en-US/US/in-the-a...11180.html most small operations probably will hold off until 2020.
As for the 250+ flights that were reported, it's unlikely that the entire island sees that much traffic in a day, so there might be a lot of flights falling in and out of range that they are including in that data. However you'll see what's there once you connect up your receiver.

Automatic Dependent Surveillance-Broadcast Out (ADS-B Out)
Automatic Dependent Surveillance-Broadcast is a new way for air traffic control to separate air traffic that doesn’t rely on radar - allows for tighter aircraft spacing and higher traffic capacity in congested airspace.
ADS-B is a key component of the Next Generation Air Transportation System (NextGen) – the transition from ground-based-radar air traffic control to an automated transmission of precise aircraft position based on Global Positioning System data
ADS-B Out is a new way for air traffic control to separate air traffic that doesn’t rely on radar – allows for tighter aircraft spacing and higher traffic capacity in congested airspace
Aircraft flying in ADS-B Out airspace use GPS to determine its position and automatically transmit it – these position reports are significantly more accurate and update more quickly than radar
Compliance effective date: 2020.
