Captain’s Log: The NW Surge — Blue Marlin, Yellowfin “Barrels,” and Shallow Thermoclines

Trip Details

Trip Type: Elite Blue-Water & Reef Expedition
Region: Amirantes Group (Remire to Poivre Atoll)
Date Range: 19–27 December 2025
Duration: 8-Day Liveaboard (Vessel: Poerava)

Environmental Conditions (Captain’s Log The NW Surge) We are now operating deep within the Northwest Monsoon. As expected for mid-December, the humidity was high (88%), and we navigated short, intense afternoon squalls that served as a critical ecological trigger. These tropical showers moderated the surface temperature to a steady 28.5°C, effectively stabilizing the thermocline at a shallow 15–20 meters. This “squeezed” the bait and pelagic predators into the top layer of the water column, creating high-visibility surface action that was purely electric. Winds remained light (10–15 knots) with frequent lulls, providing glassy conditions at the edge of the Amirantes Trench.

Catch & Activity

Yellowfin Tuna: The “Yellowfin Barrels” have arrived. We encountered massive surface bust-ups pushing “sardine-style” bait balls. We landed 14 fish, including three absolute units in the 70–85kg class.
Dogtooth Tuna: 6 landed during a high-intensity session at “The Kennels” (Poivre). The largest “Doggie” went 48kg before the sharks moved in.
Sailfish: 2 landed on the troll. They were notably aggressive, charging the teasers with full dorsal displays.
Reef predators: Steady action on Bohar Snapper and Green Jobfish during current shifts at Remire Island.

The Mission: Highlights from the Water We departed Eden Island Marina at 15:00 on the 19th, trolling past Silhouette as the sun dipped. The shallow thermocline was evident by Day 2 at the African Banks, where the Yellowfin were already “mouching” on the surface at first light.

The highlight of the trip occurred on Day 5 at the Poivre drop-off. We raised a massive Blue Marlin that shadowed a school of Skipjack for nearly twenty minutes before finally inhaling a rigged Bonito on the long-rigger. After a technical 55-minute fight involving multiple greyhounding leaps, he broke off. Sad not to land him, but an epic fight.

Later that afternoon, we moved into “The Kennels” for a jigging masterclass. The Dogtooth were holding deep on the ledge, but the aggression was high. One guest experienced the “no pussy drag rule” firsthand when a 40kg+ specimen nearly spooled his Stella 20000 before he could turn its head away from the granite.

Tackle & Techniques

Marlin Trolling: Heavy-gauge circle hooks on rigged dead-baits (Bonito) .
Yellowfin Popping: XXL cup-faced poppers (200mm+) made the difference in triggering reaction strikes from the bigger “barrels”.
Vertical Jigging: We ran Pink/Glow and Silver tail-weighted jigs (300g–400g) to reach the 100m strike zone quickly through the current.
Leaders: 250lb shock leaders were the only thing that stood up to the canine dentition of the Dogtooth and the jagged edges of the trench.
