The Islamorada Hump
All About Florida Keys Fishing & Key West Fishing
______________________________________________________________________________________________________________________
Here are the GPS coordinates for navigation to productive fishing spots off the Florida Keys.
The humps are considerable bottom features. Keep an eye out for rips formed by current
changes, birds feeding and other boats working the area. Use your depthfinder. Coordinates
given, are based on a rough waypoint;

Key Largo Hump GPS: 25-00.66' N; 80-16.8'W Depth: 280-330 ft.

Islamorada Hump GPS: 24-48.18' N; 80-26.67' W Depth: 295 ft.

409 Hump GPS: 24-35.5' N; 80-35.5' W Depth: 409 ft.

A seamount is a mountain rising from the ocean floor that does not reach to the surface of the
ocean.  Seamounts often project upwards into shallower zones . These areas are more
hospitable to sea life. It provides habitat for marine species that are not found on the  deeper
ocean bottom.  A seamount may deflect deep currents and create upwelling. This process can  
bring nutrients into the photosynthetic zone. Producing an area of concentration of organisms
not normally found in an open ocean.  Seamounts may be vital stopping points for some
migratory animals. Predators like dolphin, blackfin tuna, wahoo, billfish and other gamefish  
come to fed on squid, flying fish and other  fish. This sub order of fish are feeding on the
zooplanton.

Live bait is the biggest single denominator for a successful Islamorada Hump trip. The primary
bait species are pilchards, cigar minnows, ballyhoo and mackerel scad. Hook four live
pilchards to a 50-pound teaser line, then sent them out behind the boat. Keep the bow  into the
current, idling gently in forward gear as the baits darted around 30 feet back from the transom.
Throw a scoop of pilchards back on top of them. The free swimmers clustered around the
teaser, creates a ball of bait. Attracting the cruising fish 20 to 80 feet below. Then set your bait
on 20-pound spinner rod.
