quality grading and nutrition value determination of fish are. nowadays necessary for aquatic processing. the present study was conducted to investigate a new, applied and cheap method of fillet quality grading for common carp (cyprinus carpio) using fish size, based on mathematical equations. for this reason, 61 specimens of cultured market size carp were used and after filleting, their moistu...

The Old Lead Belt of Missouri was a major lead-producing region for over a century. Several large tailings piles and other industrial wastes remain behind, though mining operations in the region ceased in 1972. Samples of stream sediments and fish were collected from established sites on the Big River and Flat River Creek over a 3-year period from 1998 to 2000 to evaluate ongoing remediation ef...

The potential application of a new laser air puff system to assess poultry meat tenderness was investigated. Ninety broilers were deboned at either 1.25, 4, or 24 h postmortem. The raw breast fillets were scanned on a conveyor belt longitudinally by a laser distance sensor to obtain overall shape profiles and scanned again with a pressurized source of air (206.8 kPa). The 2 resulting profiles w...

Declines across global fishery stocks forced aquaculture feed manufacturers to search for new and sustainable components. Therefore, the aim of study was assessing nutritional value sensory properties meat common carp (Cyprinus carpio L.) fed 116 days with two blends. The control contained 5% fishmeal vegetable oils (rapeseed soybean) as sole fat sources. While in experimental diet half replace...

Increased education of consumers can be an effective tool for conservation of commercially harvested marine species when product labeling is accurate and allows an informed choice. However, generic labeling (e.g., as white fish or surimi) and mislabeling of seafood prevents this and may erode consumer confidence in seafood product labels in general. We used DNA barcoding to identify the species...

This study was conducted to determine the cholesterol and alpha-tocopherol contents of 20 marine fish and four other seafood from the Straits of Malacca. Cholesterol and alphatocopherol contents of the fish and other seafood were determined using high-performance liquid chromatography. The results showed that most of the fish contained low amounts of cholesterol, except sixbar grouper (Epinephe...

Several species of fresh water fish including common carp (Cyprinus carpio), rohu (Labeo rohita), mrigal (Cirrhinus mrigala) and rainbow trout (Oncorhynchus mykiss) are being farmed in India in order to meet the increasing demand for fresh fish. Among the fresh water fishes, rainbow trout is farmed in many parts of India. Worldwide, farmed trout production is increasing. The demand for trout in...

Identification of fish fillets usually requires the application of a molecular tool because most of the morphological traits used in species identification are removed during the filleting process. Early molecular identification methods relied on protein electrophoresis that became recognized as an official method for fish fillet identification (AOAC, 1990; Tenge et al., 1993; Yearsley et al., ...

Fish is a vital food for humans and many animals. We report an environmental monitoring study to assess the trace metals in fish species caught from Arabian Sea and commercially available in the coastal city Karachi, Pakistan. Heavy metals such as copper, iron, lead and cadmium were determined in the skin, fillet and heart of the fish species Pampus argenteus, Epinephelus chlorostigma, Rachycen...
