生物学特性     字汇 (例如 epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Occurs in rocky lake shore, particularly around man-made groynes or jetties. Found among aquatic plant meadows near the shore. Larvae and juveniles inhabit open water on lakes. Adults feed on insects and crustaceans, pelagic juveniles probably feed on zooplankton. Breeding is opportunistic (occurring at any time of the year), with a peak possibly occurring late in spring (Ref. 44894).

出现于岩石的湖岸, 特别地人造的防波堤或突堤的周围。 发现于在海岸附近的水生的植物草地中了。 仔鱼而且在湖上稚鱼栖息于开放水域。 成鱼吃昆虫与甲壳动物,大洋性稚鱼可能吃浮游动物。 繁殖是随机的 (出现在每年的任何时间), 具有一个可能地被在春天晚出现的高峰.(参考文献 44894)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
