Abstract

In this study, the assessment of metals absorption capacity by macroalgae using image analysis was investigated for the first time and compared with fish bioaccumulatio . Empirical cumulative entropy (ECE), and also empirical negative cumulative extropy (ENCEX) were used as a newly introduced (information-based) indices. The regression equation was obtained between fish tissue seawater in muscle of Sphyraena putnamiae (ENCEX = 0.2001 BAF; R2= 96.42); In the case of muscle of Liza subviridis, the regression model was as ENCEX = 0.1950 BAF; R2= 93.79. The regression equation was obtained between algae-sediment (ENCEXH. hamulosa = 0.2695 BAF; R2; 97.58). The studied indices showed a high accumulation of Hypnea hamulosa compared to the other algae (ECE = 0.2601; ENCEX = 0.3995). IQA method showed the same result exhibiting that the algae can be evaluated as a bio-indicator of element accumulation using image analysis. Image analysis can help us find macro algae with high absorption capacity without laboratory examinations.
