Drop bait or jigs over rocky reefs, ledges and hard bottom for snapper, grouper, amberjack and other structure-oriented fish. Local crews adjust the rig, weight and boat position to the depth, current and target species.
Bottom fishing places a baited rig or jig close to the seabed, reef edge or underwater structure. The goal is not always to touch the bottom continuously; the crew may suspend the presentation just above rock to reduce snags and reach fish feeding in the current.
Boat control is central to the technique. The captain may drift a productive line, make repeated passes or hold position where practical. Anchoring is used only when conditions, safety and the bottom type make it appropriate.
The same rock and reef that attract fish can cut line or snag a rig. Correct weight, leader strength and immediate pressure after the bite are essential.

Potential catches
Bottom-fishing species near Costa Rica’s Central Pacific
The catch depends on depth, habitat, bait and season. Not every species is present on every reef, and no specific fish can be guaranteed.
Primary target
Pacific Snapper
Pacific red, spotted rose, mullet and Pacific dog snapper are associated with different depths and structure.
Several grouper species can hold close to reef, rock and deeper ledges and require firm tackle.
Powerful fighter
Amberjack
Amberjack may suspend above deeper structure and respond to live bait or vertical jigs.
Additional catch
Jacks & Reef Fish
Jack crevalle and other legal reef-associated species may appear while working the bottom or water column.
Core techniques
How captains work a bottom-fishing area
Drift Fishing
The boat moves with wind and current across a reef edge or contour, covering water without anchoring.
Controlled Positioning
The captain uses the engines and electronics to repeat a line or hold near productive structure where practical.
Vertical Jigging
Metal jigs are worked through the water column and near the bottom for snapper, grouper and amberjack.
Anchoring When Appropriate
Anchoring may be considered only when bottom type, current, depth, traffic and safety make it suitable.
Rigs, bait and tackle
The setup changes with depth and current
Natural Bait
Live or cut bait may include locally available baitfish, squid or other legal natural offerings selected by the crew.
Live bait near structure
Cut bait for scent
Circle hooks when appropriate
Jigs & Artificial Lures
Metal jigs allow an active presentation and can reach fish suspended above deeper reef or ledges.
Vertical jigs
Slow-pitch styles
Weight matched to current
Leader & Weight
Heavier leader and enough weight to stay controlled can reduce cutoffs and keep the presentation in the strike zone.
Abrasion-resistant leader
Depth-appropriate sinker
Drag matched to structure
Seasonal planning
When is bottom fishing best near Jaco?
Bottom fishing is possible throughout the year. May through November is often a useful planning window for Central Pacific inshore and reef fishing, but tide, current, water clarity, bait and recent reports can matter more than a fixed calendar.
Strong current can make precise bottom presentation difficult, while very calm water is not automatically productive. The captain may adjust the depth, area, sinker weight or trip time.
Most lost bottom fish are not beaten by a long run—they reach rock, reef or a ledge within seconds. The angler must react promptly without jerking or creating slack.
Lift smoothly and reel down
Use the rod’s power and maintain contact instead of pumping wildly.
Follow crew instructions
The crew can see the line angle and may ask you to move or change pressure.
Keep the first run short
Proper drag and steady pressure help separate the fish from structure.
Choose the trip length
Half day or full day for bottom fishing?
Half-Day Reef Trip
A useful format when productive structure is reasonably close and the group wants a shorter day.
Good for many families
Nearby structure focus
Less time on the water
Full-Day Bottom Fishing
Provides time to try different depths, structures, baits and tide stages.
More fishing zones
Greater tactical flexibility
Better multi-species potential
Combination Inshore Trip
Mix bottom fishing with live bait, casting or trolling for roosterfish, jacks and mackerel when conditions allow.
Yes. Bottom fishing is possible throughout the year, with results influenced by current, tide, water clarity, bait and the selected depth or structure.
What fish can we catch?
Potential catches include several Pacific snapper species, grouper, amberjack, jacks and other reef-associated fish. Species vary by depth and area.
Is bottom fishing good for beginners?
Yes. The basic technique is easy to understand, although detecting bites and stopping a strong fish before it reaches rock takes coaching and quick reactions.
Do we anchor over the reef?
Not always. Captains may drift, repeat a productive line or control the boat with the engines. Anchoring is used only when the location, bottom, traffic and conditions make it safe and appropriate.
Can we keep the fish?
Some legal edible fish may be retained after correct identification and according to current rules and the captain’s judgment. Keep only what your group can reasonably use.
What is barotrauma?
It is pressure-related injury that can affect fish brought rapidly from deeper water. A descending device can return some release fish to depth, where pressure may recompress expanded gases.
Is a half day enough?
It can be when suitable reef or hard bottom is nearby. A full day gives the captain more flexibility to change depth, area and method.
