What an incredible day we had aboard GOOD DAY yesterday fishing in Costa Rica with brothers Lenny & Boris from New York. We tagged & released 2 Blue Marlin (170lb & 150lb) for Gray FishTag Research & lost another (est. 200lb) after a 5 minute battle. We also released a nice Sailfish & lost another. We found a HUGE group of Spinner Dolphins & Tuna but despite efforts with Live Baits & artificials we had no joy on the Tuna....clearly saved our luck for the Marlin! Safe to say the guys had a total blast! The Marlin bite is most certainly on, we have caught 5 Marlin in our past 4 trips & raised 10 Marlin in the past week.
