“…Poor correlations between BIA measurements and lipid content have been frequently observed in other fish species, such as S. fontinalis (Cox and Hartman, 2005), Rachycentron canadum (Linnaeus, 1766) (Duncan et al, 2007) and Salmo salar (Linnaeus, 1758) (Caldarone et al, 2012). According to Cox and Hartman (2005), these poor correlations may be explained in terms of electrical resistivity.…”

“…Reactance refers to a capacitor's opposition to alternating current; thus, this metric is a measure of cell membrane capacitance, which is related to intracellular volume and extracellular water volume. Best-fit linear models that relate BIA data to proximate composition information may be selected based on adjusted R 2 values (Duncan et al, 2007). According to Cox and Hartman (2005), to validate BIA method it's important to select fish with a sufficient variation in fat masses so this parameter can be adequately predicted.…”

Bioimpedance as a tool for evaluating the body composition of suruvi (Steindachneridion scriptum)

Bioelectrical impedance analysis (BIA) is regarded as an important tool for evaluating the body composition of different animals in a rapid, non-destructive, and low-cost manner. A South American fish species, Steindachneridion scriptum, known as suruvi, was selected for study in this investigation. A protocol to produce fish with different body composition was used to allow BIA to adequately predict the body composition of suruvi. The fish were fed twice each day with two different diets; a low lipid diet (8.90%), and a high lipid diet (18.68%). These dietary differences allowed suruvi specimens with different body compositions to be produced. The BIA readings were determined using a Quantum X Bioelectrical Body Composition Analyzer. Two readings (dorsal and ventral) were obtained for each fish. After BIA readings were obtained, the proximate composition of the fish bodies for each individual was determined. All of the study data were used to establish correlation equations between proximate analyses and BIA values. Strong correlations were found for S. scriptum. The highest correlations were obtained for the following pairs of quantities, using BIA data from dorsal readings: moisture and resistance in series (R 2 = 0.87); protein and resistance in series (R 2 = 0.87); and ash and reactance in parallel (R 2 = 0.82). We conclude that BIA is an effective method in determining the body composition of S. scriptum without sacrificing the fish. However, to expand the use of this new technology it is important to define strict BIA protocols to guarantee accurate estimates.Keywords: BIA, bioimpedance analysis, non-destructive method, native species. Bioimpedância como ferramenta de análise da composição corporal do suruvi (Steindachneridion scriptum) ResumoA análise da impedância bioelétrica (BIA) é considerada uma importante ferramenta para avaliar a composição corporal de diferentes animais de uma maneira rápida, não-destrutiva e de baixo custo. A espécie Sul-americana Steindachneridion scriptum, popularmente conhecida como suruvi, foi selecionada para este estudo. Foi utilizado um protocolo para produzir peixes com distintas composições corporais, permitindo a validação da BIA para análise adequada da composição corporal do suruvi. Os peixes foram alimentados duas vezes ao dia com duas dietas diferentes: uma de baixo teor lipídico (8,90%) e outra de alto teor lipídico (18,68%). Essa diferença nas dietas possibilitou a produção de indivíduos com diferentes composições corporais. As leituras da BIA foram determinadas utilizando-se o equipamento Quantum X Bioelectrical Body Composition Analyzer. Duas leituras (dorsal e ventral) foram obtidas para cada peixe. Após as leituras, para cada peixe individualmente, a composição proximal dos peixes foi determinada. Todos os dados obtidos foram utilizados para estabelecer as equações de correlação entre as análises proximais e os valores da BIA. Fortes correlações foram encontradas para S. scriptum. As maiores correlações foram obtidas para as análises dorsais a seguir:...

“…BIA is also an accurate predictor of body composition of animals (Marchello et al, 1999;Tierney et al, 2001) and fish (Bosworth and Wolters, 2001;Cox and Hartman, 2005;Duncan et al, 2007). Body composition factors such as total water, or proportion of fat tissue to lean tissue are correlated to BIA measurements through regression equations built on multiple measurements of control groups .…”

“…Therefore, research has been recently carried out to assess the optimal commercial feeds to be employed (Xiao et al, 2010;Trushenski et al, 2011). Related to cobia composition studies, previous research has focused on proximate analysis (Duncan et al, 2007;Liu et al, 2009) and fatty acid composition description (Khristoferzen, 1969;Kotb et al, 1991;Liu et al, 2009). Additionally, cobia skin gelatine hydrolysates have been investigated because of their antioxidant properties (Chow et al, 2011;Yang et al, 2008) and the HACCP system has been applied to frozen cobia fillets (Xia et al, 2009).…”
