It is found almost in all lowland waters and lakes, in some countries even in Mountain Lakes (in Europe),from the north of the Pyrenees, the Alps and the Balkans to the Urals. Missing in Scotland, in Italy and Dalmatia are found local subspecies.

Sticklebacks are fascinating animals that can be found in freshwater and saltwater around the world. Their scientific name is Pomatoschistus minutus and they belong to the Gobiidae family. These small but lively fish are also known as European sticklebacks, gobies, or gobies.

The appearance of sticklebacks is quite characteristic, making them easily recognizable in an aquatic landscape. These fish are between 4 and 10 centimeters long and their bodies are completely covered with small, colorful scales. Their colors can vary depending on the species, but generally, they have shades of green, gray, or brown. Females have more subdued colors compared to males, who can have more intense shades and colored spots in the operculum area.

Sticklebacks are known for their agile and alert behavior in the water. These fish are often found near the bottom of the water, where they hide among rocks, algae, or seashells. They are solitary and territorial animals, being very brave and curious. These characteristics allow sticklebacks to easily adapt to their environment and survive in a variety of aquatic habitats, from lakes and rivers to marshes and estuaries.

The feeding habits of sticklebacks are adapted to the area they live in. These fish are adaptable and feed on a variety of small organisms, such as insect larvae, crustaceans, and aquatic worms. They use an interesting method to capture food; they approach potential prey with fast and precise movements, sucking it into their mouths.

The reproduction of sticklebacks is a fascinating process. This usually occurs during spring and summer when the water temperature is higher. Males develop colored spots between their gill covers to attract the attention of females. After a male has caught a female's attention, she lays her eggs in a nest made in the fine sand on the bottom of the water. The male carefully guards the eggs and fry, defending them from potential threats.

An interesting characteristic of sticklebacks is their ability to breathe on land. During low tides, these fish can survive outside of the water for a few minutes because they can absorb oxygen from the air through their skin and mouth. This gives them an advantage in unstable environments or when the water quality is poor.

Sticklebacks play an important role in the aquatic ecosystem. Although they are small fish, they are food for many other species, such as aquatic birds and larger fish. By controlling populations of invertebrates, sticklebacks also contribute to maintaining ecological balance in the waters they inhabit.

However, there are also threats looming over these charming creatures. Human activities, such as the destruction of aquatic habitats, pollution, and overfishing, have a negative impact on stickleback populations. Fortunately, there are conservation efforts in places like nature reserves that try to protect these animals and their habitat.

In conclusion, sticklebacks are fascinating and important fish for the aquatic ecosystem. These small, agile, and adaptable creatures represent an interesting form of aquatic life. However, the challenges they currently face require additional conservation efforts to ensure their long-term survival in the wild.

Facts

Origin

In Romania it occurs in the Danube, in all the lowland rivers, in all the ponds, ponds and ponds, in the dead arms of the rivers, in the reservoirs, irrigation channels, in the littoral Lakes, the Danube Delta and in the puddles of the Danube floodplain, etc.

Food Oblets

Fry (chicks of oblets) feed on rotatoria and infusoria, then on coarser plankton.

Mature specimens feed on filamentous algae, Phyto and zooplankton, insects fallen on the surface of the water; old specimens consume mainly zooplankton.

It also feeds on aquatic insects and their larvae. The life span of the fish is 5-7 years. The oblet has a tasty flesh, appreciated by consumers.

Features Oblets

The body is elongated and much compressed laterally. The scales, thin, easily come off the body of the fish. The small head is also compressed laterally. The muzzle is short, the mouth small, oblique upwards. Dorsal is developed, caudal deeply hollow, with equal lobes.

The dorsal oblet is green, with strong iridescence, the sides are silvery, with a strong shimmer. The abdomen is silvery-white. The dorsal and caudal fins are grey with darker edges, and the rest of the fins are colorless, acquiring Red reflexes during the breeding season.

The oblet is usually 12-18 cm long and weighs 35-45 g. it reaches the length of 22 cm and 50 g respectively.its growth rate is slow, the oblet being a small fish. Females grow faster than males. Specimens of 22-25 cm are rare.

The oblet is a lively fish that lives in shoals, splitting in groups the mirror of the water during swimming. This happens especially when attacked by the avatar, in which case it runs away with great speed, at such moments the large bank can be observed from a distance furrowing the surface.

It lives in lowland fresh and flowing waters and hilly areas, but is also found in brackish waters. It is absent from small ponds, heavily invaded by vegetation.

It is also present in some small rivers, where it sometimes goes up to the springs, and in some lowland waters it is the dominant species. It lives mostly close to the surface of the water, but in search of food it also frequents areas on the bottom of lakes, ponds.

From the scales of the oblet are extracted crystals of guanine (through a rather complicated technological process), material that is used to dye artificial pearls and handicrafts (in commercial language, it is called "essence d'orient").

Reproduction Oblets

Most specimens reach sexual maturity at 2 years, but males sometimes at 1 year.

Between April and June, females lay eggs in several portions (3-6, more often in 3-4 portions), in a season, a female lays a total of 1000-12000 eggs, with a diameter of 1.2-1.5 mm.
