Lots and lots of golden dorado. In Bueno
November 3, 2025
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

We're still on top of the fish!!!
October 20, 2025
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

Buenos Aires, Argentina Big golden dorad
October 13, 2025
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.

Great day of fishing !!!
June 2, 2025
Today we chose a banked area crossed by a channel, approximately a 45-minute boat ride from the port. We fished with the river rising for about three hours and the rest of the day with the river falling. All fishing was done by drifting. We took advantage of the wind to cross the channel several times, heading northwest to southeast. On most of our passes, we found the fish feeding close to the bank on the windward side. We used floating lines (with a buoy) and midwater lines. We used small live fish as bait. Graphite and carbon rods. Front and rotating reels were loaded with 30-pound multifilament line. The air temperature in the morning was 5 degrees Celsius and reached 16 degrees Celsius by midday. The water temperature remained between 14.8 and 15.9 degrees Celsius throughout the day. We finally landed three golden dorado and several catfish. Many thanks to my anglers today! It was a pleasure sharing my boat with them. Captain Mauricio

Good Golden dorado bites
March 17, 2025
We went on a four-hour fishing trip. This time it was in the afternoon, after a morning with a rising river, some rain, low water pressure, and a strong northerly wind. This time we chose to drift fish in an area of banks and small channels about a 45-minute sail from the port. Almost halfway between Argentina and Uruguay. Some lines were weighted with a 10-gram lead, and one was rigged with a sliding buoy, allowing the bait to work at a depth of 80 centimeters. We used several types of live bait: eels, moray eels, and small fish with the hook through their backs. We were able to catch several golden dorado and ultimately landed six or seven on the boat. The water is still warm (25/27 degrees Fahrenheit depending on whether it's a bank or a channel), which makes the dorados very aggressive and eager to take bait. Towards sunset, the wind shifted to the south/southeast, and the intensity of the golden dorado strikes diminished. Only a few piranhas were eating our bait. We decided the fishing was done and sailed back to the port without any problems. As always, if you have any questions or would like to know more about fishing in Argentina, please don't hesitate to contact me. Captain Mauricio

Golden golden. Today the big ones bit!!!
March 5, 2025
After several days of storms and bad weather, the sun finally came out today. The wind was from the north-northeast all day. The river started to drop at 11 AM. The water temperature was 29 degrees on the banks and 27 in the channels. As bait we used small fish (catfish and sábalos), some eels and moray eels. What the Golden Dorados liked the most today were the sábalos) We fished with lines with two 8/0 hooks, mounted on a 30 lb. steel leader, one of the lines, with a buoy that helped the bait work at 80 cm. from the surface. We had bites on all of them!!! Unlike other days, today there were fewer dorados, but all were bigger (between 4 and 7 kilos) We had a wonderful day!!! Tomorrow we return to look for more Golden Dorados!! Captain Mauricio

Rio de la Plata, or the “River Plate,” has earned the impressive title of being the widest river in the world, and forms part of the border between Argentina and Uruguay. It’s also a hotbed of top angling action! For some, the idea of fi...
