| dc.description.abstract | This report describes monitoring of hydrographic conditions and salmon performance at EWOS Innovation Oltesvik in 2003. During the period March – October, dissolved oxygen (DO) and other linked parameters were continuously monitored outside and within cages stocked with salmon of 1 – 4 kg transferred to sea as smolt in spring 2002.
The fish stock was badly influenced by high temperature and occasionally low DO concentrations in September – October 2002.
From 11 June until start starvation in mid-October, three cages were added oxygen. DO concentrations, fish growth and feed utilisation were compared between cages added oxygen and reference cages (two cages without oxygen addition). Besides, feed consumption was measured on an hourly – daily basis in all five cages and these results will be presented in another report. | en_US |
