In general, air breathing in facultative air-breathing fishes is associated with an acid-base disturbance, resulting in an increased partial pressure of arterial CO2 and a reduction in.
Air breathing fishes may also be cultured in cages in running water systems like streams, canals and unmanageable waters like reservoirs. The air breathing fish culture is equally adaptable in waters unsuitable for conventional culturable species of carps as well as in carp culture ponds.

Excerpt from Research Paper: Fishes to Frogs: Respiratory Adaptation Respiration Evolution: Fishes to Frogs The energy needed to sustain life depends on the reduction of oxygen during glycolysis, thereby producing ATP, water, and carbon dioxide.As multicellular organisms began to evolve and grow in size, the ability of the inner-most cells to receive enough oxygen to carry out cellular.
Fishes use unimodal water breathing, unimodal air breathing, and a wide range of bimodal combinations of water and air breathing to obtain oxygen. This essay seeks to provide a theoretical framework in which to understand this diversity of respiratory mode. Consideration of oxygen as a resource shows that it is scarce in relation to demand and that an inadequate supply limits activity, growth.

Though culture of fishes in ponds is one of the age old professions of the world, it is ga in ing prominence, because of the realisation that this source can supply rich and proteinaceous food for human consumption. Majority of the species selected from nature for rearing in ponds belong to the family of crops (Cyprinidae).
In fishes, exploitation of aerial gas exchange has evolved independently many times, involving a variety of air-breathing organs. Indeed, air-breathing occurs in at least 49 known families of fish.
Lungfish, (subclass Dipnoi), any member of a group of six species of living air-breathing fishes and several extinct relatives belonging to the class Sarcopterygii and characterized by the possession of either one or two lungs. The Dipnoi first appeared in the Early Devonian Epoch (about 419.2.
Fishes use unimodal water breathing, unimodal air breathing, and a wide range of bimodal combinations of water and air breathing to obtain oxygen. This essay seeks to provide a theoretical framework.
The author gives an excellent general idea of air-breathing biology. With the evolution of air-breathing capacity in fishes, the circulatory system has also been adapted in various ways, in order to accommodate blood to and from the newly developed air-breathing surface.
Most fishes that can breath air are found in oxygen poor waters, like swamps, peaty bogs, and many higher temperature waters, where soluble oxygen concentration is low. Or where the weather is extreme, and the pondings will dry up. Some of these f.
Not all air breathing fish show this mechanism as some Dipnoi, lungfish for example, will still ventilate using the primitive two-stroke mechanism (Burggren and Johansen, 1986) and even though there can be mixing of expired and fresh air in the lungs, there has been no significant evidence to suggest that this is any less effective than the four-stroke method as breathing accessories allows.

Culture of air breathing fishes 1. MURRELS(Channa) There are serval species of murrels ,of which Channa marulius, C.punctatus and C.striatus are more important as food fishes .C.marulius grow to maximum length of 1200mm. where as C. striatus and C.punctatus reach 900mm. and 300mm respectively.
Breathing air is a requirement for fishes if they were to leave the water and invade land as tetrapods. The oldest known bony fish fossils date back to 430 million years ago from China.
