Due to ram-pressure stripping, jellyfish galaxies are thought to lose largeamounts, if not all, of their interstellar medium. Nevertheless, some, but notall, observations suggest that jellyfish galaxies exhibit enhanced starformation compared to control samples, even in their ram pressure-strippedtails. We use the TNG50 cosmological gravity+magnetohydrodynamical simulation,with an average spatial resolution of 50-200 pc in the star-forming regions ofgalaxies, to quantify the star formation activity and rates (SFRs) of more than700 jellyfish galaxies at $z=0-1$ with stellar masses$10^{8.3-10.8}\,\mathrm{M}_\odot$ in hosts with mass$10^{10.5-14.3}\,\mathrm{M}_\odot$. We extract their global SFRs, the SFRswithin their main stellar body vs. within the tails, and we follow theevolution of the star formation along their individual evolutionary tracks. Wecompare the findings for jellyfish galaxies to those of diversely-constructedcontrol samples, including against satellite and field galaxies with matchedredshift, stellar mass, gas fraction and host halo mass. According to TNG50,star formation and ram-pressure stripping can indeed occur simultaneouslywithin any given galaxy, and frequently do so. Moreover, star formation canalso take place within the ram pressure-stripped tails, even though the latteris typically subdominant. However, TNG50 does not predict elevatedpopulation-wide SFRs in jellyfish compared to analog satellite galaxies withthe same stellar mass or gas fraction. Simulated jellyfish galaxies do undergobursts of elevated star formation along their history but, at least accordingto TNG50, these do not translate into a population-wide enhancement at anygiven epoch.
