Fish Species in Chile

Besides its great fishing destinations, Chile also offers an attractive variety of species, many of which are especially destined for fishing purposes.
Trucha Arco IrisOncorh ynchus mykissShape: robust, compressed body, longer in females than in males. Short and convex head. Round, small terminal mouth (except for adult males). From 100 to 140 scales in the lateral line.
Color: Variable. The upper part of its body ranges from bright green to brown, and its lower part is silver. Along its sides, there is a red-violet stripe, iridescent, which is characteristic of this species. The head, operculum, the body and dorsal, caudal and anal fins, are densely covered by small black spots.
Size: It can reach to more than a meter long, fish usually caught measure between 30 and 60 centimeters long.
Distribution: It is one of the most common trout in the country. It is mainly found from the central zone to the extreme south of the country.
Habits: They can tolerate temperatures greater than 18º C, and their growth-rate is very fast. They reproduce in waters with a current, spawning at the end of winter and spring. Preferably, they are found in fast-moving waters and deep lakes. They are essentially carnivore.
Trucha Fario Salmo truttaShape: Long and compressed body with a high caudal peduncle. Big and long head. Round and long mouth. The maxillary exceeds the upper rim of the eye (longer in bigger fish). From 120 to 130 scales in the lateral line, fatty second dorsal fin.
Color: les in the lateral line, fatty second dorsal fin.
Color: Variable. The upper part is dark, with olive green or greenish brown shades. Lateral parts are lighter. An important characteristic is the presence of black and red spots on its sides. Red spots, and some black spots almost always have a wide light rim. Red spots often appear on the back dorsal fin, that in all trout is reduced to an adipose stump.
Size: its dimensions are inferior to those of a rainbow trout, reaching up to 80 centimeters long.
Distribution: from the V to the XII Regions. Sometimes, it invades sea coastal waters, especially the fjords and channels of the south zone, XII Region.
Customs: It preferably dwells in rapid waters, but they are able to develop satisfactorily in lagoons, whose maximum temperature does not exceed 20º C. It gets to its sexual maturity when it is 2 or 3 years old. They reproduce in clear, fast water; their spawning has taken place by the end of fall and winter.

Habits: of all the species introduced in Chile, this is the most demanding fish in terms of temperature, oxygenation and water transparency. Temperatures higher than 16º C are not adequate for it. Its spawning takes place in fall.
 Salmon PlateadoOncorhynchus kisutchShape: fusiform body, moderately high and laterally compressed. Conic head (bigger in adult males). Very small eyes.
