“…This method involves the addition of tannin to fish sauce and subsequent removal of the resulting precipitate, which contains protein-bound Cd. Accordingly, heavy metals are removed without using strong acids, and in shorter time periods than previously reported methods (Ghimire et al, 2008;Obara et al, 1999;Sakuta et al, 2000;Seki, Maruyama, Kawabe, & Nakade, 2006).…”

“…Scallops, especially Mizuhopecten yessoensis, are extensively cultured in the northern part of Japan. The adductor muscle is the only edible part of the scallop, and the rest is treated as waste product [2]. The huge amounts of these by-products are usually disposed of according to the strict Japanese Government regulations for waste disposal [3].…”

A feeding trial was conducted to evaluate the effect of fermented soybean meal and scallop by-product blend (3:2) (FP) on the performance of juvenile red sea bream. Five isocaloric diets were prepared by replacing 0% (FP0), 15% (FP15), 30% (FP30), 45% (FP45), and 60% (FP60) fishmeal (FM) protein with FP, respectively. Triplicate groups of fish (initial mean weight 2.83 g) were fed the test diets for 45 days in a flowthrough seawater system. The results demonstrated that growth rates of fish fed FP0, FP15, and FP30 were similar, and significantly higher (P \ 0.05) than those of FP45 and FP60. Nutrient utilization was significantly lower in FP60, with no differences found among the other groups. Dietary heavy-metal contents were affected by inclusion of FP, impacting on wholebody heavy-metal contents. In terms of oxidative stress, fish fed the FP30 diet were in the best condition, since this fish group showed the least oxidative-stressed condition as well as the highest tolerance against oxidation. In conclusion, the approach of utilizing this fermented mixture is promising and it could replace at least 30% FM protein in red sea bream diet without negative effects on performance, body composition or health of fish.

“…In some reports, no clear description was provided as to how the solid and aqueous phases were separated in the adsorption experiments (Dhakal et al 2005;Bayramoǧlu and Arıca 2008;Haroun et al 2009;Tan and Xiao 2009;Keskinkan et al 2004). However, significant numbers of researchers have been aware of the drawbacks associated with the use of filter papers and have, accordingly, used centrifugation instead of filtration (Anirudhan and Suchithra 2008;Inglezakis et al 2005;Ascı et al 2010) or, alternatively, column methods (Ghimire et al 2008), membrane (Kameda et al 2008;Zhang et al 2008) or Teflon filters (Li et al 2009) because they usually adsorb no metal ions.…”

Analytical filter papers are generally made of fibrous cellulose which has the potential to adsorb metal ions. In this study, blue band ashless filter paper was used to demonstrate one of the sources of error in the determination of the concentration of Fe , Pb 2+ and Zn 2+ ions. For this purpose, the metal ion content of standard solutions in the 1-100 mg/ᐉ concentration range was analysed via FAAS before and after the filtration process. The corresponding results and the calculated percentage errors due to adsorption are presented. The effect of pH on the adsorption process was also investigated. Activated carbon and soil samples were spiked with each metal ion and the solid phases from the resulting solutions were separated by both filter paper methods and centrifugation. In the statistical estimation of the results, the paired t-test was applied for non-filtered and filtered solutions in the concentration range 1-100 mg/ᐉ using the data analysis tools available in MS Excel  . The use of filter paper caused systematic errors, particularly at lower metal concentrations, and hence centrifugation or a filtering process using techniques other than filter paper is favoured as a better approach towards estimating the concentration of heavy metal ions from aqueous solution.
