FISH WASTE: POTENTIAL REVENUE DUMPED INTO THE SEA
Every day except for Friday, the fish market in Male’, the capital of the Maldives, produces a significant amount of fish waste, around 8-12 tons (8000-12000 kg) per day. This organic waste is just dump into the ocean near the fish market area.
This highly organic fish waste has potential to generate considerable revenue and can be turned into a commercially viable business.
Fish waste from the fish market can be best utilised in the production of organic fertilizers and composts, which have immense benefits over imported unsterilized organic fertilizers and chemical-based products.
Fish waste is dumped into the sea near the fish market area.
The Maldives Industrial Fisheries Company (MIFCO)’s fish processing unit in Lhaviyani Felivaru produces fish meal from fish waste for exports as ingredient for cattle feeds.
Fish waste can also be used in producing biogas in a process called anaerobic digestion, and is a renewable source of energy rich in methane and carbon dioxide, appropriate for energy production and could help in replacing fossil fuels in the Maldives attempts to become carbon neutral by 2020.
Anaerobic digestion is the process whereby organic materials breakdown naturally by anaerobic bacteria in the absence of oxygen and produce biogas as waste products.
In addition, in the biogas anaerobic digestion process the nutrient-rich solids left after digestion can be used as fertilizer

good article.
you can also make rihaakuru from fish waste, as shown by the women of guraidhoo and other islands of thaa atoll and then, perhaps, turn the remaining stuff into fertilizer.
sadly, the agriculture ministry has never shown an interest in promoting organic fertilizer production or faming. instead, they’ve always aggressively imported and sold chemical fertilizers and pesticides (even some which are banned in other countries) to farmers.
god knows how much poison is in the soil of islands like thoddoo.

Appropriate measures should be taken to dispose of waste from fish. Dumping fish waste into the sea will also create water pollution in the area.
Biological and chemical constituents of the fish waste will be detrimental to the aquatic fauna and flora (if there is any) in the area it is dumped into.
Concentration should also be given to remove float-able and settling solids. That include screening, sedimentation, and flotation to remove oil and grease and other suspended solids.
The large quantity of fish waste dumped into this area can also cause dissolved oxygen depression as well as odor problems.

Fish waste can be also used to make bio fuel.
A potential buyer of fish waste is Canada.

yes more over its can be used to manufacture fish food and food for animal where its a high end market in Europe where millions of euro’s are spend of per food. in fact Maldivian fish catch is the most reputation in the whole world, therefore its left over will be as good as the best. what do you do with your science is technology envoy in Europe ? windmill is not what we want it will destroy the Geology of the islands and its delicate nature.
what waste, what waste

it is not so fun. after 2-3 years or even early such dirty collector will produce infections epidemy and it will be terrible. before during prezident Mamoon it is never was like today. at present time in Maldives we can see total crash of health protection and anti epidemy,hygiene control systems. it may cost humans life in future, and ecological disaster .local fish market it is not only point around Male where you can see dust in water.

This wast comes from nature and goes back to nature!
I cannot see anything wrong in it! But truly is a waste that can be turned to our benefit!
I cannot see this as the big disaster Uschi Wetzel from Germany see it! But truly it is a waste that can be turned to our benefit.
Natural solutions cannot cause any danger to noting!
Nature can balance and will balance itself unless we try to fiddle with it!
But this truly is a waste and need a lot more investment than idea and sketches!

ys nature go to nature in open ocean but here all dast from fish market have no nature filtration system because it is narrow place and cement wall configuration is not according hydrodynamic design
that is why see water not properly circulate so dust will be collecting and create bacteriologycal problems.why it is so difficult to understand?
