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!

Big golden dorad
Buenos Aires, Argentina Big golden dorad
Oct 13, 2025 Buenos Aires
We had a wonderful day of fishing! We started the day with the Ain River rising. The water temperature was around 20 degrees Celsius, with a slight north/northeast turn. The first casts were at the mouths of streams that bring clear water and plenty of small fish, which are food for the golden dorado. We set some lines with natural bait (preferably pieces of yellowtail catfish caught locally) and eels. The clear water and the fish's constant predisposition allowed us to also fish with artificial lures. Until midday, we fished in this area and were able to land several small and medium-sized golden dorados and some permit and piranhas. As the tide began to change, we also changed locations and navigated to the banks and channels well out in the river. The wind was also changing and was now shifting to the east/southeast. In this area, we chose to drift fish. We used larger bait (sabalos and medium-sized yellowtails) on lines rigged with steel leaders and without any weights, so that our baits could work as freely as possible. During this second part of the day, we were able to land several dorados weighing between 5 and 7 kilos, which put up a tough fight. The oddity of the day was that spinning isn't usually done in the middle of the Rio de la Plata—the widest river in the world. The chances of landing dorado using this type of fishing are extremely low. Nevertheless, my client began casting, alternating lures and searching at different depths. The point was that we could see the golden dorado hunting quite close to our boat until one of them, about 6 kilos, fiercely took one of the lures. The golden dorado, with quick and powerful runs, forced the angler to completely circle the boat. This is the first time, in 37 years of guiding on the Rio de la Plata, that I've seen a golden dorado take a lure in the middle of the river, using the spinning method. Congratulations to the angler! As always, if you have any questions regarding this fishing, please don't hesitate to let me know. I'll get back to you as soon as possible. Thank you very much, and keep your lines taut.
