Effects of oxygen deficit on post-smolt salmon. Trial II

The study at EWOS Innovation in Dirdal was conducted as collaboration between EWOS Innovation and Rogaland Research. Tests of the effects of dissolved oxygen (DO) deficit on salmon post-smolt are a vital part of the on-going R&D project involving EWOS Innovation – OxSeaVision (OSV) – RF. The reported study was carried out at high summer temperature (mainly ca. 15 °C) – unlike the formerly reported study conducted at 8 – 9 °C.EWO

Hydrographical monitoring emphasising dissolved oxygen at EWOS Innovation Oltesvik 2003

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.OSV, EWO
