Chesapeake Sees Unprecedented Jellyfish Scarcity

In one of the wettest summers on record, as boaters dodge floating debris sent down from the Conowingo Dam, jellyfish have been few and far between. In fact, scientists tell Bay Bulletin that bay nettles, the jellyfish we know best, may be more scarce this year than ever before.

Multiple factors resulting from this summer’s rain are probably contributing to the scarcity of nettles. Salinity in many areas has been below levels that nettles can tolerate, let alone reproduce. The high water flow rates we’ve seen this season have physically washed nettles and ctenophores (comb jellies) out of tributaries and down the Bay. And, says Breitburg, over several decades, rising water temperatures have reached levels that are harmful or even lethal to jellyfish.
