Two varieties of above-ground water tanks are seen at the back, and the workers are working in an underground storage pool. [2] Radioactive water from the Fukushima Daiichi Nuclear Power Plant in Japan began being discharged into the Pacific Ocean on 11 March 2011, following the Fukushima Daiichi nuclear disaster triggered by the TÅhoku ...
In 2021, Japan's Nuclear Regulation Authority warned that the some of 3,373 waste storage containers for the radioactive slurry were degrading faster than expected. Due to the fact that transferring the slurry to a new container was very time consuming, this posed an urgent problem. [195] Tanks used to store the water were expected to be filled ...
Solid wastes: include skin, viscera, fish heads and carcasses (fish bones). Solid waste can be recycled in fish meal plants or it can be treated as municipal waste. [14] Liquid wastes: include bloodwater and brine from drained storage tanks, and water discharges from washing and cleaning.
When Mexican biologist Carlos Rosas dips his hand into the water of a large open-topped tank and brings it to the surface, there is a tiny purple baby octopus, no bigger than a tennis ball, in his ...
Waste stabilization ponds reproduce these biological phenomena before they take place in the receiving surface water and cause the pollution problems due to oxygen consumption. The ponds receive wastewater, and, by natural processes similar to those that take place in the surface waters, carry out stabilization of the organic matter inside them ...
Offshore aquaculture. Offshore aquaculture uses fish cages similar to these inshore cages, except they are submerged and moved offshore into deeper water. Offshore aquaculture, also known as open water aquaculture or open ocean aquaculture, is an emerging approach to mariculture (seawater aquafarming) where fish farms are positioned in deeper ...
Biofloc Technology. Biofloc technology (BFT) is a system of aquaculture that uses "microbial biotechnology to increase the efficacy and utilization of fish feeds, where toxic materials such as nitrogen components are treated and converted to a useful product, like a protein for using as supplementary feeds to the fish and crustaceans."

A fish factory, also known as a fish plant or fish processing facility, is a facility in which fish processing is performed. They are commonly located near bodies of water but can be located inland and on fishing vessels. The availability and variety of fish influences the scale of fish factories and the processing methods they utilize.
