After the billfish left us a bit perplexed in February with great numbers to the north along the Nicoya Peninsula and very little action to the south by Quepos, we were hoping that March would bring a return to normalcy. We are still in the midst of a historic pandemic however, so why did we even bother? The billfish continued to be feast or famine in March as the fortunate boats would find pockets of sailfish while others would have to spend the day searching for schools of yellowfin tuna. The flip side of that was the absolutely insane sailfish numbers that were registered by some of the private yachts fishing out of the Los Sueños Marina for a week in mid-March as they took advantage of a rare “biomass”. The black marlin bite was better than expected, the inshore fishing remained productive, and the bottom fishing turned on. Read on for our full Costa Rica Fishing Report – March 2021.
