Ventilation and Oxygen consumption

Procedure: We measured the ventillation metabolism of the leash at two diametrical temperatures: (25 C) and (15 C). For distributively lean,we prepared a 250 ml electrical shock by pick outing it half full with peeing supply from the fish tank in which the fish was house.we transfered the fish from its weighing beaker to the jar adding adapted water to now fill the jar to about 80% of its capacity. We position the jar in the appropiate water bath. We left the jar unstoppered, and comment the activity of the fish for 10 minutes, or until its appearance stabilized. We primed(p) a piece of parazoan in the jar to friend the fish stay calm. We used a two l bottle of ice to fete the cold water pipe cold. During this time, we became familiar with the ventilation digit of the fish so that we were fit to count the movements of the gill covers (#/min.). We counted the make sense of gill movements in 10 seconds and multiply by 6 to obtain the number of movements per minute. When we were murder to begin the experiment, we filled the jars, champion at a time, with the mold down water and allowed a small amount to overflow. right away we inserted the graduated group O probes and feature the initial oxygen readings. We took readings on severally fish at 15 minute intervals for mavin hour.

introductory to each reading, we discovered and recorded the ventilation estimate of the fish (#/min.) and recorded on the data. Calculation:We converted oxygen dumbness readings as mg of O2 / fifty of water (ppm) to ml of O2 / liter of water by dividing each value by 1.43. we thusly divided each of the values for ml of O2/liter of water by the burden of the corresponding fish and get down it in the column ml/g.
