Comments on: FISH WASTE: POTENTIAL REVENUE DUMPED INTO THE SEA

The item of dumping fish waste can be seen in the perspective of economy (household of mankind) or ecology (household of nature), the latter of which includes economy. In economy it may be feasible to use fish waste as food, fertilizer, fodder for farmed animals or for production of biogas. Apart from initial costs for small factories and training of staff, this would be profitable in the long run. In an ecological view, dumping into the sea means partly returning nutrient to the ocean (in this view the fate of total organic waste of the Maldives should be debated – not only the minor waste from the fish market). Wild fish can be seen as “free living farmed fsh” and like farmed fish they need nutrients for survival and growth. These days overfishing is discussed in many oceans of the world, but giving back fish-waste to the sea would reduce some effects of overfishing. It seems (mainly from information on bluepeacemaldive blogs) that maldive governement agencies through passive or active measurements inhibit most sound environmental decisions (like for instance bulding of a sewage water treatment plant, which could easily be combined with recycling of valuable organic waste). However, Maldives may face worse problems. The 2004 tsunami was hitherto the most devastating event in the modern history of the Maldives. But the potential rise of sea level due to climate effects may prove even more disastrous. Ironically the important tourist industri presently is totally dependent on large CO-2 emissions, participating in rising sea level (can tourist transportation be transferred to sailing transports?). Does the Maldive governement plan to transmigrate the whole population in some future? Is this the reason they do not seem to act in “local” environmental or health related topics?

During early 90s there came up a project in the Min of Fisheries & Agri . under the UNDP assistance called ‘ fish waste utilization ” 2 foreign experts came and did a very thorough servey. it was found very feasible to produce Silage for using as fertilizers. They did test products and made tests,a senior staff of that ministry who worked as a local focal point and project manager did found foreign market for unrefined crude silage which will then be a new export product. UNDP provided basic machinery and other equipments (worth more than $100,000) to be installed at Male fish market where all fish waste to be ground into paste when it is fresh ,add preserving chemical and pack in 200 ltr. drums.
Suddenly fisheries ministry’s administration changed and the new minister was very much influenced by a newly employed staff who was the daughter of president’s brother. The result was that project suddenly became not a viable one and stopped. All the valuable equipments that was stored in a warehouse in k. Viligili, got corroded and no body knows where they are now.

We can reduce much of this waste even, by eating most of the fish, we Maldivians have habit of preparing these fish, that we waste so much of edible part of the fish. Historically Maldivians have different style of handling fish. specially tuna. I think by slight changes how we prepare these fish for cooking, even we can save lot of fish. If we cut the fish with bones the way neighboring countries do. Remove only stuff in the stomach of fish, the rest we can cook and the reaming will be only bones to through.

My opinion is to abolish this fish preparing area to encourage people to take the whole fish to home and eat most of it.

Scientifically its proven now, that fish protein is good for your heart, and may be that’s the reason we have less cardiovascular disease in Maldives, by eating less oil and more fish we may have more health benefits too, if we can prepare them properly so we consume most of it.

producing bio gas in not a practical process in maldives..u must consider cost efficency as wel..but there are many other cost effective methods whereby we can treat and dispose off fish waste in an effective way

If we can get some local support, we can bring in multi-fuel engines for power generation, which can leverage the fish oil as the fuel for these engines. And thus go green and reduce the diesel fuels.

thanks

I see a big potential and banned product in Male these Fish waste can be contribute to many factors , these waste can converted to fish silage and feed to Pigs (banned) its slurry (liquid based) these are been proven in most of the Europe country such Sweden and Denmark or for poultry feed this is very cost effective , i have already commenced 10000 liters capacity project in Srilanka .

i have heard about it, and so i would like make factory for “organic fertilizer in Madives to protect from ocean pollusion.

We are one of manufacturer of Organic fertilizer using fish in korea.

Please inform me how to do to set up factory in there, and wish to know if we can sell its near Maldives.

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?

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!
