We examined the effects of resource value on contest dynamics of round goby fish. Round goby fish strongly preferred enclosed over open shelters. Fish needed prior experience with the resource to assess its value. Experienced fish adjusted their aggressive effort to reflect resource value. Fish seemed unable to update their assessment of resource value during contests.
