title: [Energetic metabolism during individual development of Lymnaea stagnalis (Lymnaeidae, Gastropoda): III. Late postlarval ontogeny].
abstract: Changes in the rate and intensity of oxygen consumption during individual ontogeny of 14 specimens of Lymnaea stagnalis in the period from the 10th week after emergence until death was investigated in aquaculture. It was demonstrated that the rate of oxygen consumption increased and the intensity of this process decreased during the whole period of observations. Alterations of these parameters were accompanied with permanent oscillations of their meanings. The correlation between intensity of oxygen consumption (q) and age (t) can be described with the equation q = q(st)(1-exp(-k(g)(t+t0))). The values of coefficients of this equation do not differ significantly between individuals and, on average, comprise k(g) = 0.0696 +/- 0.0072 weeks(-1); q(st) = 60.42 +/- 2.6 mcl O2/(hour(g)); t0 = -3.0 +/- 0.7 weeks. The dependence of the rate of oxygen consumption (Q, microl O2/h) on body weight (M, g) for all data is significantly described with the allometric equation Q = 0.369M(0.779).
