Cardiorespiratory physiological phenotypic plasticity in developing air‐breathing anabantid fishes ( Betta splendens and Trichopodus trichopterus )

Cardiorespiratory physiological phenotypic plasticity in developing air‐breathing anabantid fishes (Betta splendens and Trichopodus trichopterus)

Developmental plasticity of cardiorespiratory physiology in response to chronic hypoxia is poorly understood in larval fishes, especially larval air-breathing fishes, which eventually in their development can at least partially "escape" hypoxia through air breathing. Whether the development air breathing makes these larval fishes less or more developmentally plastic than strictly water breathin...

Environmental modulation of the onset of air breathing and survival of Betta splendens and Trichopodus trichopterus.

The effect of hypoxia on air-breathing onset and survival was determined in larvae of the air-breathing fishes, the three spot gourami Trichopodus trichopterus and the Siamese fighting fish Betta splendens. Larvae were exposed continuously or intermittently (12 h nightly) to an oxygen partial pressure (PO2 ) of 20, 17 and 14 kPa from 1 to 40 days post-fertilization (dpf). Survival and onset of ...

Amphibious fishes: evolution and phenotypic plasticity.

Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favou...
