Mauritius offshore report shows active yellowfin tuna and dorado bite

Mauritius just flashed a real yellowfin signal, and the numbers matter: one dorado, plus yellowfin tuna at 41 and 90 pounds, came off the productive offshore grounds around Le Morne on May 18. For traveling tuna anglers, that is the kind of report that cuts through the noise. It says the fishery is not only holding tuna, it is holding fish in two classes at once, with one fish solidly in mid-size range and another pushing into better-class territory.

Maranatha Sport Fishing, a 40-foot offshore sportfishing boat based in Le Morne, put the fish on deck with Captain Antonio Lamarque running the program. The report was short, but the haul was specific enough to tell a useful story about the bite. This was not a single isolated hookup. It was a mixed pelagic outing in the same general area, with tuna and dorado showing together, which is exactly the kind of spread that usually points to life in the water, bait presence, and current lines worth following.

That matters because Mauritius is not a routine stop for most yellowfin hunters, so every current catch report has trip-planning value. The 90-pounder is the headline fish here. A tuna that size suggests the area is not just producing schoolies. Bigger fish are in the mix, and that changes how a trip gets judged. If the goal is to book around a shot at a serious yellowfin, Le Morne just offered one of the better signs you can ask for: a charter with local legs, working a known offshore zone, landing multiple tuna and a dorado on the same run.

The timing fits too. Mauritius season guides put yellowfin tuna strongest from roughly March through May, while dorado are commonly targeted from May through September. That overlap makes a mid-May report especially useful, because it lines up with the shoulder of one pattern and the start of another. Le Morne and the southwest coast keep turning up as major offshore grounds for tuna and other pelagics, and Maranatha’s own profile says the operation has worked the southwest coast of Mauritius for more than 30 years.

There is also some repeatability baked into the report. Maranatha’s recent archive has shown more tuna trips, including a May 2026 outing that produced a 29-pound yellowfin and four skipjacks. Put that next to the 41- and 90-pound yellowfin now, and the picture is cleaner than a one-off bite. Mauritius offshore is active, the bait is around, and Le Morne is looking like a place worth circling if you want yellowfin with a real chance at a better fish.
