N°3 | The Spined Stickleback

N°4 | The Vendace fish

The vendace fish belongs to the Salmonidae family. Its average size is 45 cm and its weight is 1 kg. The oldest specimens observed were 10 years old. It breeds from October to December. The female lays 30,000 eggs per kg of weight. It is fished from March to December. The vendace is a small, slender and streamlined fish that is very easy to confuse with a bleak, a small lavaret whitefish or a peled whitefish. Unlike the bleak, the vendace is a member of the Salmonidae family, which is why it has a fat fin. It differs from the lavaret and peled whitefish by its much longer lower jaw. In the lavaret whitefish, the upper jaw is longer and in the peled whitefish the jaws are of the same length. It is silvery on the sides, with a white belly and a brown-green, grey-blue or blue-green back.

Fishing period : from March to December

Minimum size : 30 cm

N°5 | The Minnow fish

The Minnow fish belongs to the Cyprinidae family. The minnow is a small fish with a length of 4 to 10 cm (maximum 14 cm) and a weight of 3 to 10 g (rarely more than 13 g). Life expectancy is 4 to 5 years (maximum 11 years). Reproduction takes place from April to July or from one region to another. Depending on size, the female lays between 200 and 1000 eggs. It can be fished all year round. It moves in benches. It is often accompanied by trout of the same size and young salmon. The body is shaped like a spindle. The head has a rounded snout, the mouth is terminal (the upper jaw slightly protrudes from the lower jaw). The back is dark green, the upper part of the flanks is light brown with large black-brown spots (sometimes linked to form stripes), while the lower part is yellowish green with silvery highlights, the belly is creamy whitish (in spawning season, it is copper red in males). The lateral line usually only extends to half of the body. The caudal peduncle is compressed laterally. The fins are rounded and transparent. The caudal fin is clearly indented; the ridge is quite high.

N°6 | The Rudd fish

The Rudd fish belongs to the Cyprinidae family. The current size of the rudd fish is 15 to 30 cm for a weight of 0.5 to 1 kg. It can reach nearly 51 cm in height and weigh 2 kg. The rudd fish can live about 17 years. Egg laying is split and takes place from April to June. The female lays 100,000 to 200,000 eggs. Fishing for rudd is allowed all year round. It is easily identifiable by the diver: the silvery appearance of its body. A closer look at the position of the dorsal and ventral fins will then make the difference between the two species. If the ventral fins are placed further forward than the dorsal fin, it is the ratchet. The mouth, small, terminal, opens obliquely upwards. The back of the rattlesnake is brownish green, the sides and belly are silvery. The iris of the eyes is yellow with golden reflections. Dorsal, anal and pelvic fins are bright red in color.

N°8 | The Sunbleak fish

The Sunbleak fish belongs to the Cyprinidae family. The usual size of sunbleak is 4 to 6 cm for a weight of about ten grams. The largest individuals can reach 9 cm. Its lifespan is about 2 years. It breeds between May and July. It is prohibited to fish for the sunbleak in white water from October to March, but in mixed and calm waters it can be fished all year round.

Its head is small with eyes that are excessively large in relation to the size of the head. Its lower jaw is longer than its upper jaw, giving its mouth a forward and upward orientation, indicating a fish that feeds preferentially on the surface. The caudal fin of sunbleak is particularly indented, its dorsal fin fits well behind the pelvic fin insertions. The sunbleak has an olive-brown back, bluishly reflective sides and a silvery belly. Its fins are light grey.

N°9 | The Roach fish

The Roach fish belongs to the Cyprinidae Family. The current size is 10 to 30 cm and the weight is 10 to 200 g. Some individuals can reach 50 cm for a weight of 2 kg.

Roach is one of the most common and widespread fish in slow-moving lakes and rivers. It lives in schools of individuals of approximately the same size. These benches can be composed of hundreds of roaches. It is easily identifiable by the diver: the silvery appearance of his body, the eyes and red fins allow him to identify roaches and rotengles. A closer look at the position of the dorsal and ventral fins will then make the difference between the two species. If these two fins are upright, it is the roach.
