Gulf and Caribbean Research

An unidentified species of hydrozoan in the family Eirenidae was inadvertently transported to the Laboratory with a stock of Mysidopsis bahia. The hydrozoan competed for food, ate the young mysids, and subsequently reproduced extensively. Hermit crabs provided minimal control. A detailed transfer procedure for the mysids eliminated the hydrozoans from cultures; hydrozoans were eradicated from tanks after removal of mysids by using 1:1200 formalin, hot water, and Clorox.
