生物學特性     字彙 (例如 epibenthic)

Adults occur in ponds, marshes, paddy fields and small flows of plains (Ref. 41299). They prefer slow-moving streams. Inhabit mainly waters of lowlands and brackish water, and also known to inhabit tide pools of coasts of certain regions in Japan and Korea. They can withstand a wide range of salinity (Ref. 58933). Omnivorous (Ref. 58933). For indoor culture, a diluted sea water is rather better than the freshwater , and the use of a balanced salt solution is recommended, if the tap water proves to be unsuitable (Ref. 58933). Used in experimental research (Ref. 4537). Non-annual breeders. Are easy to maintain in the aquarium (Ref. 27139). A fluorescent ornamental variety (genetically modified fish), a product of fluorescent protein extracted from jellyfish and attaching to DNA in embryonic fish of this is now being sold in the aquarium trade (Ref. 48573).

出現於平原的池塘,濕地,稻田與小水流。 (參考文獻 41299) 偏愛緩慢移動的溪流。 主要棲息於低地與半淡鹹水的水域, 以及知道在日本與韓國居住於特定區域的海岸的潮池。 抵抗寬範圍的鹽度。 (參考文獻 58933) 雜食性.(參考文獻 58933) 對於戶內的養殖,一個被沖淡的海水相當比淡水更好,而且被平衡的含鹽解決方案的使用被推薦, 如果自來水證明是不適合的。 (參考文獻 58933) 被用於實驗的研究.。 (參考文獻 4537) 非年度生殖者。 容易在水族館維持。 (參考文獻 27139) 一個點綴著螢光的變種 (在遺傳基因上修正魚), 一種螢光蛋白質的產品從水母吸取.,而且在胚胎魚中吸附到 DNA 現在這正在在水族貿易被賣。 (參考文獻 48573)

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=0.00479 (0.00189 - 0.01213), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
營養階層 (Ref. 69278):  3.4   ±0.45 se; based on food items.
Generation time: 0.3 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (tm<1; Fec=40).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
