The main source of calcium carbonate (CaCO₃) in the ocean comes from the shells of calcifying planktonic organisms, but substantial amounts of CaCO₃ are also produced in fish intestines. The precipitation of CaCO₃ assists fish in intestinal water absorption and aids in whole body Ca²⁺ homeostasis. Here we report that the product formed in the intestinal lumen of the gilt-head seabream, Sparus a...

We have applied molecular approaches, including PCR-based detection strategies and DNA fingerprinting methods, to study the ecology of Listeria monocytogenes in food processing environments. A total of 531 samples, including raw fish, fish during the cold-smoking process, finished product, and environmental samples, were collected from three smoked fish processing facilities during five visits ...

The fisheries products in this study comprise fish, bivalve, crustacean and cephalopod collected from different types of markets in Taiwan between the years 2001 and 2003. A total of 91 pesticide residues belonging to four major pesticide groups were tested and analyzed. The test results show that 65.40% of fish, 93.55% of shellfish, 84.92% of crustacean and 98.33% of cephalopod samples contain...

The risks of contamination of finfish products with active pathogens largely depend on the type of product concerned and disposal methods of the importing country. Frozen fish used as bait or to feed high-value species present the greatest risk as vehicles of contamination because they are unprocessed. Freezing preserves viral- and some bacterial-pathogens, thus the use of such fish as bait can...

This study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size/weight measurement and condition f...

OBJECTIVE To identify attitudinal determinants of fish consumption in Spain and Poland, and to discuss the potential impact of local healthy eating policies in the observed reported frequency of fish consumption. DESIGN Repeated survey analysis , multivariate linear regression analysis. Data collected through a questionnaire that included socio-demographics, self-reported anthropometrics, as ...

BACKGROUND The purpose of this study was to explore the cross-cultural differences in the frequency of fish intake and in motivations for fish consumption between people from households with (CVD+) or without (CVD-) medical history of cardiovascular disease, using data obtained in five European countries. METHODS A cross-sectional consumer survey was carried out in November-December 2004 with...
