Common names: Techirghiol stickleback
Occurrence: extirpated
Salinity: freshwater
Abundance: | Ref:
Importance: | Ref:

Regulations: | Ref:
Uses: no uses
Comments: Previously found in freshwater springs of hypersaline littoral Lake Techirghiol (south of Constanta). Has been extinct due to the hybridization with Gasterosteus aculeatus. Springs inhabited by Gasterosteus crenobiontus were previously separated from habitat of Gasterosteus aculeatus by a hypersaline lake that served as a barrier between the species. Irrigation activities transformed the lake into a brackish one which was invaded by migratory Gasterosteus aculeatus (Ref. 59043). Status of threat: extinct (Ref. 59043).

Краткое описание определительные ключи | морфология | морфометрия

Distinguished from congeners in Europe by possessing two unique characters: 13-17 scutes on trunk, no scutes above anal base; and posterior edge of scutes smooth. Differs further by having scutes forming a lateral keel on caudal peduncle (Ref. 59043).

биология     глоссарий (например epibenthic)

Adults inhabit springs. Mature individuals spawn in February - October (Ref. 59043). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
