Member since January 2019 Buenos Aires, Argentina
Background
I've been fishing since I was 3 years old, and sailing since I was 18 – now I'm over 50 years of age, and I have fished and sailed in waters all over the world! I practice almost all types of fishing. I manage and direct my own fishing, nautical and tourism services, and graduated in Social Communication and Counseling. During part of my working life I worked in corporate companies, managing the commercialization of services with global clients, which has led to me becoming fluent in 3 languages. When I go on vacation, I choose destinations where I can combine my free time and plenty of rest and relaxation with...fishing!

Today we went on a 6-hour excursion. We left the port around noon. The tide was in its last two hours of incoming flow. We had a light east-northeast wind. We sailed for approximately 45 minutes to a very good fishing spot at this time of year. It's a series of sandbars and channels with a strong current. Many small fish move there, which are the main food source for golden dorado. We began our first drift over a very hard sandbar, in no more than 3 feet of water. There we had the first bites and managed to land our first golden dorado. As we ran out of water for our drift, we moved to different spots. In all of them, we had very good bites from dorado ranging from 3 to 7 kilos. We used size 10 hooks, tied to 80-pound steel leaders. Today, none of our lines had weights, so all the baits worked in mid-water. In the mid-afternoon, we had a delicious snack. There were different kinds of cold cuts, cheeses, and olives. Around 5 PM, with the wind shifting to the southeast, we began our return to port. The fishing trip yielded: 7 dorado caught on the boat, others that managed to escape, and a new experience fishing on the widest river in the world: the Río de la Plata. Captain Mauricio

Today we're going to talk a little about numbers! When we set out, the tide was at 1.80 meters above sea level and going out. We returned with it at 65 cm above sea level. The fishing trip lasted 6 hours. Two fishermen came and managed to land 10 golden dorado on the boat. 4 more got away alongside the boat. Some of the golden dorado were within the average weight for this time of year (2-3 kilos). Others weighed up to 6 kilos and had their stomachs full of fish. We used size 10 hooks with 30 cm steel leaders. We started the morning with 18 live baits. We finished fishing with 4 baits. Which indicates that the percentage of fish hooked was very high. The water temperature is 22 degrees Celsius, and the air temperature started at 20 degrees in the morning and reached 29 degrees by the time we returned. Another beautiful day of fishing, very close to Buenos Aires, on the widest river in the world (Rio de la Plata). See you soon! Captain Mauricio
