the objective of this study was to produce fish protein hydrolysate (fph) with the most antioxidant activity, by enzymatic hydrolysis from (carassius carassius). the protein of crucian carp a low value fish was hydrolyzed by alcalase 2.4l and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (rsm) by the central rota...

Dactylogyrus spp. are monogenean worms found mostly as ectoparasites on the gills of several fish species, including carp and goldfish. These parasites are commonly detected by microscopic analysis of the gill lamellae, but this is time-consuming and technically difficult. In contrast to this conventional method, molecular techniques provide specific, sensitive and safe detection of parasites. ...

BACKGROUND Fish consumption may prevent or improve metabolic health. The aim of this study was to identify associations between fish consumption, both fatty and lean, and metabolic syndrome and its components. METHODS Associations between fish consumption and metabolic syndrome and its components were studied in a large sample from a Norwegian population (N = 23,907), using cross-sectional da...

Dietary intake of omega-3 fatty acids has been positively correlated with cardiovascular and neuropsychiatric health in several studies. The high seafood intake by the Japanese and Greenland Inuit has resulted in low ratios of the omega-6 fatty acid arachidonic acid (AA, 20:4n-6) to eicosapentaenoic acid (EPA, 20:5n-3), with the Japanese showing AA:EPA ratios of approximately 1.7 and the Greenl...

Present study was carried out to determine the larvivorous activity of fishes was found in Lower Manair Dam to identify the potential fish species for consuming larval forms. The listed 58 larvivorous potential fish species were collected and identified in the laboratory based on the morphometric and meristimatic characters. Pelagic feeders occupy 25.59%, bentho pelagic feeders occupy 24.14%, d...

For newly settled coral reef fishes, survival advantages may be associated with specific early life history traits or condition levels that lead to differences in behavior. To identify physiological and behavioral characteristics associated with different condition levels, bluehead wrasse Thalassoma bifasciatum recruits were collected immediately after settlement from reefs in the upper Florida...

there are 61 species in 14 families of fish-eating birds in iran. the fish-eating birds of the north of iran belong to 41 species in 10 families which include 67.2 percent of total fish eating bird species and 71% of fish-eating bird’s family of iran. resident birds constitute 13% of the fisheating birds of the caspian sea coasts and the rest are migratory in autumn and winter. there exist 3 ...

A simple and rapid method was developed for the analysis of tetrodotoxin in puffer-fish tissues, and in serum and urine of humans poisoned after consuming puffer-fish, by means of high-performance liquid chromatography with tandem mass spectrometry (LC/MS/MS). Tetrodotoxin was extracted with 2% acetic acid. The extracted solution from puffer-fish tissues was diluted with water, and the extracte...

This report presents a new approach for the detection of large man-made objects in a rural area using a single monochrome image. In this problem, man-made objects may be unspecified and the appearance of the objects is unpredictable. Prominent features discriminating man-made objects from natural objects are identified. A computational framework for applying perceptual organization and using th...
