Costa Rica Fish

Inshore and Outshore!

Fish are all over Costa Rica in lakes, rivers, Inshore and Outshore, This is what makes Costa Rica Fishing so popular. You can’t go anywhere with out seeing them in the waters. There is different types of fish that we will be discussing. Firstly popular sports fishing Fish and the different species you find Inshore and Out Shore.

Fish Seasons

Offshore fish are some of the biggest and most popular fish you will find in Costa Rica waters. This is especially so in the months of December through April. That is because of the sheer number of fish that show up during that time.  Most anglers think it is due to the rainy season that the fish dissipate but this is far from true, fish don’t care about rain they are already wet. Rather it is because of the wind current shift. Billfish, Dorados, and Tuna rely on Oxygen rich waters for proper nutrients and from May-Nov those water just don’t exist near Costa Rica. During the High season, there are two ocean currents that push all this oxygen enriched water towards Costa Rica. Also, you will find out that two strong wind currents from the Gulf of Mexico and Caribbean blow this water back out from the Costa Rican shores. So with water currents pushing one way and wind currents pushing the other way, this puts a large concentration of fish in the Central Pacific area.
