Book excerpt: Excerpt from Studies on the Reproduction and Artificial Propagation of Fresh-Water Mussels The writers' personal attention has in the main been directed to a study of the conditions of reproduction in the group and the parasitism of the larva in their bearing upon the problem of artificial infection of fishes with glochidia, while such phases of the investigation as geographical distribution, systematic studies, and a number of special ecological problems have been in the hands of other investigators. At the recently established biological station of the Bureau of Fisheries at Fairport, Iowa, while construction was still in progress, the work of propagating some of the commercial species was inaugurated, and the excellent facilities of the station, which has been especially designed for the purpose, are now being utilized by members of the stafi in attacking fundamental problems of both a scientific and an economic nature.

The result, however, is much as Latter describes if a little of the fish's blood gets into the water in the neighborhood of the glochidia, except that our experience has shown that after snapping for a few seconds they come to rest in permanent closure. It therefore seems possible that the contractions seen by Latter were due to the introduction of some blood with the tail of the fish, as otherwise agitation of the glochidia under similar conditions has not been observed by us. Since the hooked and hookless glochidia, whose reactions to blood and to certain salts we have studied, show important differences in their behavior, they are referred to separately below REACTIONS OF HOOKLESS GLOCHIDIA. It was first observed that glochidia of the hookless type, in marked contrast with the hooked forms, only occasionally exhibit spontaneous contractions and respond either not at all or only sluggishly to tactile stimuli, and the question at once arose as to what causes their closure when they become attached to fish. If the stimulus which brings about a contraction of the adductor muscle in attachment is not a mechanical one, it presumably is chemical in nature, but we were completely in the dark in the matter until it was cleared up by the following experiments, the first of which were made with the glochidia of Unio complanatus at Woods Hole, Mass. When a small drop of blood of either the killifish, Fundulus diaphanus, or the white perch, M or one americana, was placed over the glochidia contained in a small amount of water in a watch glass, the effect was immediate and very striking. Every glochidium was thrown into rapid and violent contractions, alternating with relaxations, the edges of the valves either quite or nearly touching with...
