Abstract
    Factors affecting the predator-related mortality of sand goby Pomatoschistus minutus (Pallas), common goby P. microps (Kroeyer) and brown shrimp Crangon crangon L. were investigated in Gullmar Fjord, Sweden. Substrate selection and locomotory activity was recorded in the 3 species on sand and on mud. Sand goby and brown shrimp preferred sand to mud, while common goby preferred mud to sand. Activity was clearly correlated to substrate type. In all 3 species, swimming activity was increased by a factor 4 when kept on the less preferred substrate.
