Dorado (salminus maxillosus) The Dorado lives in Northern, South Argentina , Brazil, Bolivia, Paraguay and Uruguay. A beautiful fish, has the form of the body of a salmon
and the head of bluefish.It is a formidable predator and a sport fish I magnify, equipped with jaws of steel trap and acute teeth of knife. Mature Dorado can weigh more than 20 kg (45 pounds) and get to measure
1.20 mts. (4.5 feet).
He is a terrible, similar combatant to tarpon but more aggressive; the normal thing is to receive pieces of between 3 and 9 kg (6 to 20 pounds) of pure golden steel muscles.
Although these fish always have been here, single recently have been discovered by the foreign fisherman, its complete aggressiveness does perfectly rich a sport fish for the fishing with fly and spinning. As resulting from this increasing enthusiasm
we have specialized in capturing these acrobatic beasts with artificial. So it is so the government has determined immense and inhospitable exclusive zones of fly-fishing and spinning for catch and release with hook without flash.
The Dorado is, with no doubt, the more significant of the native species. Their sport qualities have transferred our borders, transforming it into a fish of international fame. Fans worldwide
have in their retina the image of the Dorado making their acrobatic jumps, as if he was a gold bar twisting in the air when he is accompanied by the sun and sprinkled by the water.
Its particular yellow-orange color is propped up by an aggressiveness that few fish equal to him. All the owner of river does outside as if, where he practically does not have enemies. Its strength allows him to attack without mercy shoals of fish of
small fish (in general, of mojarras) or ale vines of other species. 
The Dorado ambushes its prey, often hidden under stones, trees, aquatic plants and other obstructions. It prefers, the mouths of streams or inner courses that upset in the other greater one where two adjacent currents
join.
When lowering the level of the main river, the smaller fish are forced themselves to leave their refuges because they are in shallow water. Thus, as soon as they arrive at the most important channel, the Dorado is waiting for its pray and its luck seems thrown. These torrent waters are one of the main points that the Dorado chooses to provide itself with food. And, therefore, one of the sites that the sport fly-fisherman must
always consider at the time of looking for Dorado.
Some of the qualities of this fish that also usually denominates pirayú or tiger of the river are that it counts on a mouth almost totally bony, provided of strong conical teeth. This solid structure implies that the nailed one must be very precise and
signs not to fail.
Another remarkable aspect of the Dorado is its way to fight; it offers a very frank fight, to discovered face and raises the dispute to open field. It makes by far vigor at the first moments, where are combined forts
attacked and spectacular jumps. Bond to remember that it does not stop being ethical to follow the piece when the implements are very below the required power.
The fan will be able to forget many captures, but never he will do it of apprehended Dorado in these circumstances. The essence of this activity does not happen to accumulate captures, but to release each one on them . Another valuable
condition of the species is that it offers the possibility of being captured in different styles.
Fly-cast can be practiced as much in open rivers as in streams, that has east type of fishing on traditional with bait or the decoy, is that where often enters the fly
the others cannot enter, because there are trunks, plants, is under the place, etc., however the fly does not have disadvantages and we have been very good successful, mainly the Dorado when it does not eat, has its territory and attacks more by irritation
than by hunger.
With respect to the characteristics there is nothing defined, and its possible to be fished in very shallow places, like in the heat of Paraná (where sometimes its more than ten meters deep) with equal results. The bigger river are
not problem either, on the contrary, favors this type of fishing, because when raising the normal levels causes that the water is introduced in the islands and produce small tracks, that are ideal places for the Dorado, because they are on the lookout
for its food, thing that does not happen when the river is in its normal level.
Also the turbidity or transparency of the water does not influence for anything, the species perfectly takes the cloudy water fly also. The rod ideal for equipment is number 8, has some prefer rod, more powerful like number 9, because
the Dorado is difficult to stop, and there is no more possibility than to let the boat drift and follow them. For more exquisite fishing, its the rod number 7, you have a much more pleasure and enjoy it much
With a smaller equipment the risk of breakage is a possibility. Reel must have a medium size with backing of 100 to 120 meters (110 to 130 yards), later with shooting perfectly well. As far as the line, it will be preferment have preferably
to be fast sinking (the best ones Dorado take down). In experiences with popper or floating we have been successful, but the moments are few that can be practiced this type of fishing, only when the fish eat above and are very voracious. This is a
unique fishing, to see the Dorado almost on the surface and take the lures, its wonderful.
The flies must be of quite great sizes, some by big volume of hair, for that reason it is important to have very powerful
rods to be able to cast this type of fly, some of these sometimes are even ballasted, because if the
Dorado is well down its necessary to sink the flies to be successful.
Many fishermen who go the first time to this zone, usually insist with the subject of the fording; this style is not recommendable because our waters are plagued of stingrays, which usually lye on the bottom and as the water is generally
brownish, it does not allow them to 
detect the flies.
It would be very disagreeable to undergo the puncture of a ray sting, in addition the great percentage of the fishing is made on board, some times we go to shore, and we walk by clean places, mainland, where there are not trees that
can bother. All this is single a small sample of the immense amount of sport possibilities that the Dorado offers too us, seasoned almost always by anecdotes and surrounded by landscapes of incommensurable beauty that accompany each excursion to the
river.
