The Relative Weight (Wr) Condition Index As A Predictor Of Growth, Prey Abundance And Environmental Conditions, Hongsheng Liao
Masters Theses
We evaluated the relative weight (Wr) condition index for assessment of growth, prey availability and environmental conditions in fish populations. Standard weight (Ws) equations for pumpkinseed (Lepomis gibbosus) and golden shiner (Notemigonus crysoleucas) from 302 pumpkinseed and 285 golden shiner populations, with well over 10,000 fish of each species, were developed with regression-line-percentile (RLP) technique. The proposed Ws equation in metric units for pumpkinseed is log10Ws = -5.179 + 3.237 log10TL, and for golden shiner is log10Ws = -5.593 + 3.302 log10TL. The English-unit versions of these equations were also developed. …
