N°1 | The Rainbow trout

The Rainbow trout belongs to the Salmonidae family. On average, it measures 35 to 70 cm and weighs 500 g to 6 kg. In this species, a maximum lifespan of 11 years has been observed. Rainbow trout reproduce naturally from late March to early July. Fertility is about 2000 eggs per kg. Depending on the region, it is fished from March to September. Rainbow trout have a streamlined, laterally compressed and slender body. It has a small head and a slightly split mouth. Its body is arched at the level of the dorsal fin. It should also be noted that there is an adipose fin common to all Salmonids. Its scales are small and thin. Generally, the entire body is punctuated by small black spots, many on the back and sides, as well as on the dorsal and caudal fins. The back is olive green and the sides are silvery. The color of the belly varies from white to yellowish. Nevertheless, the general coloring of the body varies greatly depending on the age, habitat and physiological stage of the fish. The particularity of rainbow trout lies in the presence, all along the body, of an iridescent longitudinal band, predominantly pink. During the breeding season, the female is generally rounder because of the ovarian volume, while the males appear to be more elongated. They become darker and their colors more vivid.

N°3 | The Ghost Carp

The Ghost Carp belongs to the Cyprinidae Family. With a life expectancy ranging from 40 to 50 years on average, it can reach up to 80 cm long. The breeding period is short, from May to June. The female lays 100,000 eggs per kg of weight. It can be fished all year. From its transition from young to adult fish, many physical characteristics will change. Its scales change color over time, as does its size. Many people tend to confuse a young ghost carp with a goldfish because of its physical appearance and colors. However, the two species are distinguishable: the ghost carp has a flat belly while the goldfish has a more swollen belly. In addition, towards her lips we notice barbells similar to two small moustaches in the ghost carp.

It has an elongated body, silvery grey, bluish grey, with a more or less brownish back and fairly large scales. The caudal fin is very indented. The mouth is small. Two details that differentiate it from other salmonids. The number of gillospines (here 15 to 70) confirms that they belong to that species. The male has prominent scales on the lateral line, rough to the touch.

The mouth is protractile (it unfolds forward) and free of barbells, surrounded by thick lips. The Silver bream is characterized by a long anal fin with between 22 and 26 rays, although shorter than the fresh water bream (26 to 30 rays). The dorsal fin of the Silver bream is short and high.
