Manufacturing processes in fish canning industries generate a considerable amount of solid waste that can be digested anaerobically. The aim of this research was to study the biochemical methane potential of different solid fish waste. For tuna, sardine and needle fish waste, around 0.47g COD-CH(4)/g COD(added) was obtained in batch experiments with 1%TS; whereas for mackerel waste, the methane...

Fish waste biomasses are locally available resources which contain nutrients. Fermentation of the biomass produces slurries used for plankton production and plant/agri-nutri use. Bio-refinery of fish waste material can be converted into value added biological products such as biofuels, industrial chemicals, animal and fish feed, human food, neutraceuticals and organic fertilizer, etc. Fish proc...

Marine biomass including fishery products are precious protein resources for human foods and are an alternative to livestock animals in order to reduce the virtual water problem. However, a large amount of marine waste can be generated from fishery products and it is not currently recycled. We evaluated the metabolism of digested marine waste using integrated analytical methods, under anaerobic...

A framework for the integration of poultry and fish production in the tropics and sub-tropics is proposed. Poultry may be integrated with fish culture in several ways and benefits extend to both. Both poultry production and processing wastes have value as nutrient inputs to fish and the water used for fish culture can be used for evaporative cooling of poultry and fertilization of crops. The co...

Food waste from fish and fruit shops was used as an alternative to the grain in grower-finisher pig diets. Two diets were formulated on an iso-nutrient basis (14 MJ digestible energy per kg, 160 g crude protein per kg on a dry-matter basis) to contain 0 g of food waste per kg in the control diet and 50 g of fish-shop waste per kg and 120 g of fruit-shop waste per kg in the experimental diet. In...

The world fisheries and aquaculture supplied about 142 million tons of fish in 2008, of which 115 million tons was used as human food, providing around 17 kg (live weight equivalent) per capita/per person. Aquaculture accounted for 46% of total food fish supply, a slightly lower proportion with respect to that reported in the past. Huge amount of fish and other marine organisms were eliminated ...

the study was conducted at haramaya university poultry farm to evaluate the effects of locally processed fish waste meal (fwm) in the diet of white leghorn layers on the performance and hatchability, egg quality, sensory flavor and profitability of the rations. one hundred eighty chickens at five months of age were randomly distributed (15 layers per each 12 pens). the pens were randomly assign...

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 ...

In order to utilize low economic value fish for human consumption there is a need for development of novel process for production of acceptable, shelf stable and ready to eat products. The preparation of extruded products from cereal-fish mince mixture is gaining more importance world over and as it offers many process variables to get acceptable high quality products. With more and more fish i...
