Abstract
    In an effort designed to detect differences between manually-fed inshore-farmed trout (Salmo gairdneri Richardson) and automatically computer-fed offshore-farmed rainbow trout, an experiment was conducted in 1986 at Karlshamn, Sweden, using two different sites, one inshore and one offshore. At the sheltered inshore site traditional Jamek 1 cages were used while at the exposed offshore location a large single unit fully automated Farmocean Platfarm 3500 was used. Of the same population a significant number of fish were removed from the two different farms and examined for: standard length vs weight; standard length vs circumference; and total weight vs viscera weight. A comparative analysis indicates that offshore-farmed rainbow trout acquires a significantly higher ratio of useful flesh vs viscera fat, a slimmer and more salmon-like body, and an overall superior appearance. The results also indicate a lower mortality rate amongst computer fed offshore-farmed fish. Increased activity among the fish in a turbulent environment coupled with uninterrupted feeding, seems to account for these positive findings.
