The experiences of this final season of the intensive cod fry production experiment are summed up. The brood stock yielded 369 liters of cod eggs. The production experiment in plastic pens had very high survival, but slow growth up to day 28. Between days 28 and 36 the majority of the larvae died due to prolonged insufficient ingestion. The lab experiments with cod larvae fed differently enriched roti fers supported that enrichment time should be several hours. Different enrichment mixtures did not seem to give different growth or survival. Dry feed based on cod roe did not give growth or significant survival.
