Abstract
In vivo hydrophobic crevices from which bubbles emerge upon decompression are hypothesized to account for experimental observations of bubble formation in decompressed shrimp. The conical crevice model can be used to explain the sharp increase in the number of bubbles observed in shrimp for decompression ratios greater than 4:1. In accordance with the observed attenuating effects of pressure pretreatment on bubble formation in shrimp, the model can also be used to explain: (a) the evolution of the gas nuclei to smaller stable sizes during compression; (b) the return of the nuclei to their original stable configurations when the overpressure is removed; and (c) the requirement for greater decompressions to cause emergence of bubbles from the nuclei as the magnitude and period of pressure pretreatment are increased.
