Mauricio Oñate

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!

Lots and lots of golden dorado. In Bueno
Lots and lots of golden dorado. In Bueno
Nov 3, 2025 Buenos Aires
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

Oct 20, 2025 Buenos Aires
Today we spent half a day fishing. We had a strong north-northwesterly wind, which made fishing in the open river very difficult. For this reason, we fished at the mouths of small streams along the Rio de la Plata. We used 9/0 hooks with 10-gram sinkers on an 80-pound steel leader. For bait, we used small yellow catfish we caught locally and small "sábalos" we caught with a cast net before setting out. When small golden dorados were biting, we used only pieces of bait. For larger ones, we used live fish with a leader looped over their backs. The river was ebbing all day, much more than usual due to the wind direction. We had many strikes from golden dorados and piranhas of various sizes. We managed to land a few. Around 3 p.m., we began our return to port, with the river much calmer than the one we had experienced during the outbound voyage. As always, if you have any questions, please let me know so I can respond promptly. Thank you very much, and keep the lines taut! Captain Mauricio
