簡単な記述 形態学 | 形態計測学

Diagnosed from other species of Gasterosteidae in Europe by combination of the following characters: 4-6 short dorsal spines, never inclined to the left or to the right; without keel on side of caudal peduncle; anal fin origin slightly behind dorsal fin origin; body dark olive green (getting blackish in breeding males), with numerous pale spots or undulating bars on flank (Ref. 59043).

生物学     用語集 (例 epibenthic)

Adults inhabit cool, vegetated, sand or mud bottoms of lakes and ponds. Also in pools and backwaters of creeks and small rivers (Ref. 1998, 10294). Rarely found in brackish water. Feed on crustacean and insect larvae, eggs and larvae of fishes, snails, oligochaetes and algae (Ref. 1998, 10294). Preyed upon by kingfishers, herons, and mergansers and occasionally by fishes like Salvelinus fontinalis and Esox lucius (Ref. 1998). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Males arrive first in shallow waters, establish their territories, and build small nests near the bottom. The male then entices the female to the nest and by prodding her ventral and caudal peduncle area, forces her to release her eggs into the nest. The male then drives the female away, fertilizes the eggs and guards his territory until the young hatch and swim away. Males may build two nests during a breeding season and more than one female may deposit eggs in each nest (Ref. 1998). Eggs hatch in 8-9 days (Ref. 59043).
