Figure 1. The partial-recirculating system at the Freshwater Institute serves as a nursery to grow rainbow trout fingerlings from 15 g to over 100 g. The CAD drafting was provided by PRAqua Technologies Ltd. (Nanaimo, British Columbia). Figure 2.

Results and Discussion Fish Growth and Production Over the production cycle 398 dead fish were removed (1.1%) and another 553 fish were culled (1.5%). Over the same period, the culture tank’s fish density increased from 35 kg/m 3 to as much as 148 kg/m 3 , before fish were harvested (Figure 3). Mean fish size increased from 15 grams on December 16 (1999) to 100 g on March 13 (2000), an interval of only 88 days. The fish’s specific growth rate was 2.14% of their body weight per day. During this same period, the fish biomass increased by 2,994 kg (6,586 lb) and the fish were fed 3,509 kg (7,719 lb) of feed, producing a feed conversion of 1.17.

Overall Water Quality and Water Flowrates fish split into 3 tanks Mean water quality data recorded during the study is shown in Table 1. Relevant water flow rates during the study: 1142-1847 L/min total system flow, 237-357 L/min make-up flow, and 169 L/min total bottom-drain flow. Thus, the bottom drain flow and system make-up water flow were only, respectively, 12-15% and 19-21% of the total system flow throughout the study. 5 75 kg of fish harvested 262 kg of fish harvested 382 kg of fish harvested 12/16/99 1/7/00 1/29/00 2/8/00 2/9/00 2/25/00 3/10/00 3/13/00 3/20/00 Date (month/day/year)
