To investigate community shelter effects of two invasive decapod species,Hemigrapsus sanguineusandCarcinus maenas, in the Long Island Sound (LIS), we deployed artificial shelters in the intertidal and immediate subtidal zones. These consisted of five groups during the summer: a control, a residentH. sanguineusmale or female group, and a residentC. maenasmale or female group. We quantified utilization of the shelters at 24 h by counting crabs and fish present. We found significant avoidance ofH. sanguineusin the field by benthic hermit crabs (Pagurusspp.) and significant avoidance ofC. maenasby the seaboard goby (Gobiosoma ginsburgi). The grubby (Myoxocephalus aenaeus) avoided neither treatment, probably since it tends to be a predator of invertebrates.H. sanguineusavoidedC. maenastreatments, whereasC. maenasdid not avoid any treatment. Seasonal deployments in the subtidal indicated cohabitation of a number of benthic species in the LIS, with peak shelter use corresponding with increased predation and likely reproductive activity in spring and summer for green crabs (C. maenas), hermit crabs (Pagurusspp.), seaboard gobies (G. ginsburgi), and grubbies (Myoxocephalus aenaeus).
