A study with a duration of 42 days was conducted to evaluate the influence of fish oil inclusion on performance parameters, serum lipid content, antibody responses to sheep red blood cells (SRBC) and the composition of antigen and meat fatty acids in broilers. Two hundred and sixteen 1-day-old broiler chicks from a commercial hybrid (Cobb 500) were allocated randomly to four groups, which rece...

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...

In this study, we have investigated the effects of mix of Tomato (Solanum lycopersicum) & Carrot) Daucus carota ( and red Bell pepper )Capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (Astronotus ocellatus sp., Agassiz, 1831), which are generally white with red patches in the dorsal skin. The fish were fed diets contain...

an experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (cla), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. the chicks fed with 7% fish oil or 7% cla diets, were found to have an inferior weight gain in grower and finisher phases, respectively. a...

The aim of this study was to determine the effect of fish-based feed materials, as a source of readily available protein contained in fish broth and essential polyunsaturated fatty acids (PUFAs) found in fish oil, on the health of piglets and rearing results. The experiment was conducted on a commercial pig fattening farm. The study involved a total of 80 weaners with an approximate body weight...

Fish meal and fish oil replacement has been the focus of very significant research efforts and hundreds of scientific papers in recent years. Despite years of research, fish meal and fish oil remain very important, quasi essential, components of successful commercial feeds for most fish and crustacean species. This generally has an impact on the feed and production costs for many aquaculture pr...

Aquaponics is the science of integrating intensive fish aquaculture with plant production in recirculating water systems. Although ion waste production by f ish cannot satisfy all plant requirements, less is known about the relationship between total feed provided for f ish and the production of milliequivalents (mEq) of different macronutrients for plants, especially for nutrient flow hydropon...

Concentrations of 160 polychlorinated biphenyl (PCB) congeners or congener groups were determined in approximately 600 farmed Atlantic salmon from around the world and wild (ocean-caught) Pacific salmon from the Northeast Pacific. Concentrations and PCB congener profiles were analyzed to provide insight into the sources and uptake of PCBs in salmon as well as regional differences. Although tota...
