- Abstract:
- The accuracy and feasibility of multiple methods for determining energy condition in Chinook salmon were determined. These results were compared to proximate analysis of fish tissues, which represented the true value of energy content for these fish. Although all estimate methods produced results that were significantly correlated with proximate analysis, bioelectrical impedance and condition factor were less accurate than morphometrics and the Distell Fatmeter. Bioelectrical impedance did not seem to be as accurate in salmon as with other fish species, and is generally considered of better use for mammals. Although condition factor was included as a factor in many models to predict energy condition, its lipid estimation qualities by itself are suboptimal. From a series of 12 morphometric measures, breadth at anus, hump height and mideye to hyperal length together provided the best method for determining lipid content. These three measures were used in subsequent years. Although morphometrics proved to be the most accurate method for estimating energy condition, the Distell Fatmeter was also accurate, and had the added benefit of a reduced handling time. Either of these two methods are recommended to be used in further research when a quick and accurate measure of lipid content is needed.
