Swim Bladder Inflation

The minnow ( Phoxinus phoxinus) was raised up to the stage of swim bladder inflation at temperatures between 10°C and 25°C, and the time of development significantly decreased at higher temperatures. Accordingly, initiation of cardiac activity was observed at day 2 in 25°C animals and at day 4 in 12.5°C animals. Only a minor increase in body mass was observed during the incubation period, and, at the end of the incubation period, animals raised at 25°C did not have a significantly lower body mass compared with animals raised at 15°C. Metabolic activity, determined as the rate of oxygen consumption of a larva, increased from 3.3 to 19.5 nmol/h during development at 15°C and from 5.6 to 47.6 nmol/h during development at 25°C. Heart rate showed a clear correlation to developmental stage as well as to developmental temperature, but at the onset of cardiac activity, diastolic ventricular volume and also stroke volume were higher at the lower temperatures. Furthermore, stroke volume increased with development, except for the group incubated at 12.5°C, in which stroke volume decreased with development. Initial cardiac output showed no correlation to incubation temperature. Although metabolic activity increased severalfold during development from egg to the stage of swim bladder inflation at 15°C and at 25°C, weight-specific cardiac output increased only by ∼40% with proceeding development. At 12.5°C, cardiac output remained almost constant until opening of the swim bladder. The data support the notion that oxygen transport is not the major function of the circulatory system at this stage of development. The changes in heart rate with temperature appear to be due to the intrinsic properties of the pacemaker; there was no indication for a regulated response.

Polychlorinated biphenyls are a widespread aquatic contaminant. In this article, specific polychlorinated biphenyl congeners were examined for embryo and early life-stage toxicity in zebrafish ( Danio rerio). A set of three polychlorinated biphenyl congeners (non-ortho polychlorinated biphenyl 126, mono-ortho polychlorinated biphenyl 28 and di-ortho polychlorinated biphenyl 153) were tested. The typical lesions observed were yolk sac edema, vertebra defect, craniofacial malformations (double head, triple retina), anaxial body and inhibition of swim bladder inflation. Moreover, embryo and larval mortality increased and hatching success decreased. The severity of abnormalities and mortalities were concentration- and congener-dependent. Of the compounds tested, polychlorinated biphenyl congener 126 was found to be highly toxic to the fish embryos following exposure. The Lethal Concentration 50 values for polychlorinated biphenyl 28, polychlorinated biphenyl 126, polychlorinated biphenyl 153 calculated by probit analysis were 3.270, 1.298 and 5.375 ppm, respectively. The inhibition of swim bladder inflation was the most sensitive endpoint measured, and it is suggested that the inhibition of swim bladder inflation may be mediated by mechanism with an aryl hydrocarbon receptor activation.
