The golden dorado, scientifically known as Salminus brasiliensis, is a freshwater fish found primarily in the rivers of South America, particularly in the Paraná, Paraguay, and Uruguay river basins. Known for its striking golden color and powerful build, it can grow up to 1 meter in length and weigh over 30 kilograms. The golden dorado is a popular target for sport fishing due to its aggressive nature and acrobatic fighting style. This species thrives in various freshwater habitats, including rivers, lakes, and reservoirs. The golden dorado primarily feeds on smaller fish and insects, making it a carnivorous predator. Conservation efforts are in place in some regions to protect its populations from overfishing and habitat loss, ensuring that this iconic fish remains a vital part of its ecosystem.
