The team tracked individual plankton them from birth to death and exposed them to various concentrations of sodium chloride (rock salt) and calcium chloride.
In case anyone thinks sand is automatically a better option, it’s not. Fine particles settle in the benthic layer of streams and ponds, smothering everything that needs exposed gravel beds for their life cycle. This impacts invertebrates directly (harming everything that eats them) and disrupts many fishes egg-laying.
