Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Some experts believe that some form of copulation happens during breeding of this species. The female turns on her side to expose her abdomen to the male who then swims against her in a forceful movement. Aftewards, the female takes a rest and deposits her eggs in the sand. This whole activity is presumably repeated one more time (Ref. 205). Other experts believe otherwise, that only a simple and simultaneous discharge of gametes happens during breeding (Ref. 205).北美洲: 原產於聖勞倫斯河 - 五大湖，哈得遜灣 (紅河) 與密西西比河流域。 引入了在美國的其他地方。 原住民在田納西州與俄亥俄州的部分被保護。

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5157 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00371 - 0.00647), b=3.08 (3.02 - 3.14), in cm total length, based on LWR estimates for this species (Ref.
93245).
營養階層 (Ref.
69278): 4.5 ±0.3 se; based on diet studies.
Generation time: 6.4 (5.5 - 7.1) years. Estimated as median ln(3)/K based on 25
growth studies.
回復力 (Ref.
