| Breathing exchanges of Pinna nobilis L. are studied in situ and in the laboratory with two methods. First method consist in introducing samples of Pinna under a 40l plexiglass bell equipped with haps. The bell is positionned by diving. The consumption of oxygen is observed with water samples and the oxygen concentration is measured with an electronic oxymeter. Experiments which are carried out during nycthemeral cycles are reproduced in the laboratory with the same type of bell. A second method carry into effect an apparatus more sophisticated, who put into circulation a current of water in an airtight thermostated cellule, where a specimen of young Pinna is introduced. This sample is gradually adaptated to the conditions of the medium. Breathing... |
