See text. the production tanks was 10-50 times higher than in pre- vious trials (1-5 kg irT3 versus kg m^3). The in- creased biomass became a problem also in the production tanks near the end of the G, and G2 generations, but no mortalities could be associated with these increased levels. Nitrite levels (recommended < ppm) were held below NO2-N ppm in the hatchery tanks and below ppm in the production tanks. Nitrate levels NO3-N were never a problem in the hatchery tanks because of the short duration of the culture period and the low bio- mass, but the levels in the production tanks eventually exceeded our goal of <50 ppm in the Gp (84 ppm) and G2 (62 ppm) generations (Fig. 4). Note the similarities in the respective slopes of the biomass and nitrate curves.
