Summa y and Cmlusions The losses of nutrients in the cooking and plate waste of milk, eggs, fish and meat and the losses in the storage and preparation of vegctables have been studied. Records are presented also of waste in school and other canteens. Scrambling is the most wasteful method of cooking eggs. Thermostatically controlled panv would reduce the waste in cooking eggs. The filleting of ...

A small assemblage of sieved fish remains was analysed from a medieval site on Lindisfarne. Haddock, cod and whiting were the most commonly consumed species, with small numbers of other taxa recovered, including herring and flatfish. Most were probably caught in local inshore or coastal waters, and most were only of moderate size. It is likely the remains include gutting and processing waste (i...

Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around open-cage salmonid farms in Norway on the environment and human activities and on the interactions of these impacts. Waste fish feed is considered the major cause for the att...

agricultural waste biomass generated from agricultural production and food processing industry are abundant, such as durian  peel, mango peel, corn straw, rice bran, corn shell, potato peel and many more. due to low commercial value, these wastes are disposed in landfill, which if not managed properly may cause environmental problems. currently, environmental laws and regulations pertaining to ...

INTRODUCTION A mercury (Hg) processing plant previously operating in KwaZulu-Natal Province (South Africa) discharged Hg waste into a nearby river system causing widespread contamination since the 1980s. Although the processing plant ceased operation in the 1990s, Hg contamination (due to residual Hg) remains significant. Previous studies in the area since the plant's closure have found elevate...

Bacterial populations contaminating various tissues of fish cultured in fish ponds fertilized with different organic wastes have been studied. Twenty-five genera of bacteria were identified as associated with the fish tissues. The identified bacteria included one genus of spiral and curved bacteria, one genus of Gram-negative aerobic rod, sixteen genera of Gram-negative facultative anaerobic ro...

The necessity of energy is continuously increasing, whereas fossil fuel sources are gradually depleting. To mitigate this problem, fish processing waste the bluespotted stingray (Neotrygon kuhlii), available in Borneo region, was investigated for an alternative feedstock bioenergy production. wastes hazardous environment, biodiesel from pollution-free and produces less contaminant gas carbon di...

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...
