Exempel på hur du använder WELS i en mening

• Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa.
• It is stocked with perch, trout (rainbow, brown, brook), carp, European chub, common rudd, common roach, pumpkinseed, wels catfish, Danube Bleak and various members of Carassius.
• Although the banks of the reservoirs are comparatively hard to access, it attracts many visitors and sports fishermen because of the abundance of fish, including native species such as European perch, common chub, river trout, Eurasian carp, crucian carp, Prussian carp, wels catfish and common rudd, as wells as alloctonous ones like grass carp and rainbow trout.
• There are some accounts of wels catfish (Silurus glanis) growing up to 350 pounds and having a lifespan of up to 50 years in the area.
• The river is inhabited by many autochthonous fish species, including common roach, European chub, common minnow, riffle minnow, common rudd, asp, Vardar nase, European bitterling, common gudgeon, round-scaled barbel, Macedonian vimba, Eurasian carp, Struma spined lorch, Balkan golden loach, wels catfish, river trout, European perch and Western tubenose goby.
• The wels relies largely on hearing and smell for hunting prey (owing to its sensitive Weberian apparatus and chemoreceptors), although like many other catfish, the species exhibits a tapetum lucidum, providing its eyes with a degree of sensitivity at night, when the species is most active.
• Fishes living in the surrounding waters include wels catfish, zander, common carp, common bream, silver carp, northern pike, sterlet, common barbel, asp and various other types of freshwater whitefish.
• There are 54 fish species including clupea, caspian kutum, common carp, wels catfish, sander marinus, common bream, flathead grey mullet in the water basins of this reserve.
• However, a number of organisations are concerned in attempts to preserve this species and a captive breeding scheme has been established, with young microchipped fish released into the wild officially since 2004, following EU projects (Life03nat/IT/000113 and subsequents); before 2004, almost only post-larvae and very small sturgeons were released (since 1988), at a time when fishing of sturgeons was still allowed in Italy (until 1997) and the allochthonous wels catfish (Silurus glanis) was at the apex of its numerical expansion in Italian rivers, so the survival rate was extremely low.
