The effects of density (50, 55 and 60 kg fingerlings/drum of 200 litre) on the mortality and essential water quality variables were assessed for silver carp Hypophthalmichthys molitrix fingerlings in a simulated transport experiment. The second experiment involved the determination of the effects of knowing the optimum loading density 50 kg/drum fingerlings on the mortality and water quality in silver carp advanced fingerlings for standard 8 hours transport simulation. Six hours of simulation duration resulted in less than 1% mortality and 8 hours caused about 6%. Third experiment with highest density 60 kg/drum fingerlings at 500 g/l of advanced rui (Labeo rohita) fingerlings was used for a period of 6 hours since the quality of the transport medium was deteriorated due to regurgitated stomach contents. The fingerlings were unconditioned and fed. Level of immediate mortality was only nearly 3% at 6 hours of simulation duration. This study has clearly demonstrated that the optimum loading of silver carp fingerlings per drum is 50 kg. The minimum concentration of dissolved oxygen (DO) concentration for maximum survival is 2 mg/l for silver carp fingerlings. Silver carp advanced fingerlings can be transported for 8 hours duration by using 2 phenoxyethanol at the concentration of 115 μl/l with oxygen injection. Rui advanced fingerlings can be transported at 60 kg/drum (500 g/l) for 6 hrs duration even if the fingerlings are unconditioned. Dhaka Univ. J. Biol. Sci. 27(1): 9-16, 2018 (January)

Postcolumn Derivatization

Abstract A liquid chromatographic method with postcolumn derivatization is described for determination of biogenic amines in fish and fish products. Histamine, tyramine, serotonin, β-phenylethylamine, tryptamine, putrescine, cadaverine, agmatine, spermine, and spermidine can be determined in less than 60 min. Routine sample preinjection treatment implies only 2 extractions with 0.6N perchloric acid and filtration through a 0.45 μm filter. Lack of interferences from volatile amines, amino acids, and dipeptides was verified. Results of reliability study were satisfactory. The proposed method was linear for each amine between 0.25 and 8.00 mg/L. Average recoveries ranged from 92 to 103%. Precisions (coefficients of variation) ranged from 0.70 to 9.75%. Determination limits were ≤1 mg/kg. A modification in LC conditions was necessary to apply the method to ripened fish products to avoid interferences from food matrixes. In addition, stability of biogenic amines in fresh anchovies and hake during short-term frozen storage was studied. Results showed that, except for agmatine, frozen storage is suitable for keeping samples before analysis.

Ozone Treatments

Physicochemical changes of myofibrillar proteins from silver carp surimi during frozen storage as affected by two manners of ozone treatments were investigated. For preparation of surimi treated with ozone, ozone water (8 mg/L) was used in either the first (To1) or the second (To2) cycle of rinsing. As compared with control samples (Tc) (rinsing two cycles with water), myofibrillar proteins from To1 surimi showed slightly lower free sulfhydryl contents and higher surface hydrophobicity throughout frozen storage and lower Ca2+-ATPase activities after 30 d. To2 did not significantly (P>0.05) affect these physicochemical properties, indicating that myofibrillar proteins structure was well maintained. Consequently, To1 significantly (P>0.05) decreased breaking force of surimi gels while To2 did not significantly (P>0.05) affect gel breaking force. In addition, the whiteness of surimi gels was increased more obviously by To2 than by To1. The results indicate that To2 could be used as a mild oxidation treatment for improving white color of silver carp surimi without negatively affecting gel texture.
