Key messages

  • A replicated study in Australia recorded lower levels of amoebic gill disease in salmon kept within larger compared to smaller cages.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. In 2000, a replicated study in Tasmania, Australia (Douglas- Helders et al., 2004) found higher levels of amoebic gill disease salmon, Salmo salar, stocked in 60m diameter round cages compared to those in 80m diameter cages. Levels of amoebic gill disease were 47% and 22%, respectively. Two cages with a diameter of 60m and three of 80m diameter were used for the study. Average biomass per pen was 2337 kg for the 60m cages and 2806 kg for the 80m cages. Monthly samples were taken from August to November. Signs of clinical disease were assessed using the routine Tasmanian salmon farmers gill assessment method.
