Cobitis taenia | Male | Male sexual dimorphism | Male were identified in the field by the presence of a lamina circularis, a plate-like ossification on the base of the second pectoral fin ray. This structure de velops in males of 45-50 mm TL and is present in all males > 50 mm TL | Present |
Cobitis taenia | Spawning conditions | Spawning migration distance | Short-distance migrations prior to spawning have been suggested for some Japanese loaches but not for European populations | No data |
Cobitis taenia | Spawning conditions | Spawning season | From April to July | ['April', 'May', 'June', 'July'] |
Cobitis taenia | Spawning conditions | Spawning period duration | It appears that males enter the shallow littoral zone earlier in the season, and are joined later by the females during spawing. | No data |
Cobitis taenia | Spawning conditions | Spawning depth | Shallow water | No data |
Cobitis taenia | Spawning conditions | Spawning substrate | Dense vegetation | Phytophils |
Cobitis taenia | Spawning conditions | Mating system | Durnig spawning season, females spawn in a 6 days interval and each spawning act lasts 3-5 H. Consequently each male in the population would have spawn each day with three to four females, on average 14 h per day during the whole spawning season | No category |
