| This study was designed in Marine Sciences station (Aqaba) during the period September 2000 to October 2001 . The study of the effect of body weight on the metabolic rate revealed the presence of a proportional relationship between the metabolic and body weight and the presence of inverse relationship between the metabolic and body weigh.In snails acclimated to 10 ºC, 20 ºC, and 30 ºC, the Weight specific metabolic rate was influenced by both acclimation as well as experimental temperature. Thus, the oxygen consumption rate increased 1n 10 ºC acclimated snail from 44 µl O2. gˉ¹ . hrˉ ¹ to 105 µl O2. gˉ¹ . hrˉ ¹ As a result of increasing the experimental temperature from 10 ºC to 30. ºC In 20 and 30 ºC acclimated snail, and as a result of increasing the experimental temperature from 10 to 30, the weight specific oxygen consumption rates increased (20 ºC and 30 ºC ) from 40 µl O2. gˉ¹ . hrˉ ¹ to 88 and 35 to 85 µl O2. gˉ¹ . hrˉ ¹ Respectively. Snails acclimated to 10 ºC ,20 ºC and 30 ºC showed Precht s type 3 normal the(partial) compensation in weight specific oxygen consumption rate , since at all experiment temperatures , the highest oxygen consumption rate was observed in 10 ºC Acclimated animals, whereas the lowest rate was observed in 30 ºC acclimated snails. |
