Introduction One of the major expenses in any fish culture operation is the cost of feeds for the fish, and the profitability of many operations is frequently tied to the cost of feed. Hatchery production of fish larvae most often requires the expensive production of live food (phytoplankton and zooplankton), because artificial diets are either not available, or are grossly inadequate. Artifici...

Feed waste results in increased production costs to the cage fish farming industry and produces negative environmental impacts. A computerized system, consisting of digital scanning sonar and current meter, was developed for monitoring, assessment, and optimization of the fish feeding process. The system can detect and monitor quantity and direction of wasted food pellets and also predict the t...

Tannery hair wastes are becoming a challenge for tanners regarding environmental pollution control and human health. In this study, an experiment had been designed to hydrolyse sheep in alkaline medium, the operational condition extraction of KH has modeled optimized. The structure, morphology, functional groups, particle size, molecular mass extracts were evaluated experimentally by scanning e...

For the purpose to reveal the substance as the source of offensive odor of the fish from the sea facing petroleum and petrochemical industries, analyses have been made on the sea water, industrial wastes, offensive odor fish meat and the eels kept in the sea or industrial waste for a certain period, by means of gas chromatography, infrared, and ultraviolet absorption spectrophotometries and mas...

Fish are highly nutritious food items. In most countries, fish is one of the significant sources of animal protein and essential nutrients for the maintenance of health and protection from different types of diseases, such as blood pressure, cancer and heart stroke [1]. Sea food products reduce vulnerability to hunger by providing a complementary food source when other food sources, such as agr...
