A device for handling fish eggs and other benthic macro invertebrates is provided for removal from a surface of a waterway. An enlarged, generally planar housing has a lower surface formed of a material having sufficient flexibility so that a vacuum that communicates through a collector cavity can remove fish eggs, for example, from a waterway. Fish eggs can be destroyed, either with high pressure fluid that may be a part of the vacuum assembly, or mechanically destroyed, or alternatively the fish eggs may be filtered or separated from the remainder of the collected material. Fluid such as water, saline, chemical or toxins, warm water, etc., are preferably introduced into the waterway surface about the periphery of the housing to treat and/or dislodge the fish eggs.
