I have not seen an actually FAD, only pictures from the internet. Most of them are saltwater based and look like a floating bouy anchored to the bottom or suspending just below the water surface.
Another 1 is a traditional kind that ties palm leaves onto ropes like a tampan jig, it is than tied down from a raft like bamboo platform and weighted down at the end of the palm rope to keep it vertical.
My own idea was forming a square out of PVC pipes. Within the square, water lettuce can be planted inside as their leaves and long hairy roots proved good shelter. The square structure will be anchored to prevnt it from drifting. Floating plants will also be easier to harvest if it over grows.
Hope it isn't a stupid idea ;D

1. Will the FAD cause enviromental concerns including water quality?
I believe PVC is used in our own water systems too and it is a save material to use in reservoirs as well.
If we want to secure the joints together, we can use silicon and i think it is save as well.
As for anchoring the FAD, i am not very sure of which material is most suitable.
The water lettuce will help to remove nutrients in the water and should not have any detrimental effects unless it dies and decomposes.
2. Is this the best idea where minimum input = maximum output without compromising on point #1?
This is the part where i think we can only decide after hearing more opinions and suggestions from fellow fishermen.
3. Are we well-equiped to execute the idea?
I'm am not sure about the scale of the FAD we're looking at but if possible i am willing to fix up the thing at my house, i have most of the tools needed. We will most probably need transport which i don't have. And we might need some chiping in for us to buy the necessary materials.
I am just curious if the authorities would allow us carry out the plan even if proven that it is 100% save just as raised in the other thread.

a FAD sounds like a good plan! however, what i noticed was that when i feed my sebbies is that they hang out in the drift wood and the lil fishos hang near the filter pipe. so if we have a FAD, the predators will probably hang out at the bottom so if we have a FAD, its gonna have to be like a pretty big artificial reef.
changing the topic! good news! i have smsed my fish supplier's phone number to Uncle Yu Hock and i asked about the price for sebbies and lampans. the prices are as follows... should be lah...
sebbies 100 too 199pcs - $1.20 each Sebbies 200pcs and above. - $1.00 each
Lampan 100 pcs to 199 pcs - $1 each Lampan 200pcs and above - $0.80 each
size will be around 3 inches.
Best Regards
An Ren

Hi Billy, I share your aspiration. Let us hope our enthusiasm goes from this forum to the actual field. Thanks YH. Qwek will be spearing these aspirations when the time is right. Anakin, An Ren, Guo Rong, Fosey and the other younger fly fishermen will be needed to see to it that these aspiration is carried beyond our generation and beyond. We're all be giving our fullest support when Qwek give the signal to go....................

Hi Folks,
We need everyone support to get the new club, the white papers and this adoption program going. We are please to know these support are coming in, keep them coming. I will be starting another thread to compile a contact list which will include those who do not surf the internet or this forum. Thanks once again.
Hi An Ren, Lampams good. Any chance of tarpon as well. Been think of these fishes which hopefully are not the poachers' diet, but knowing them even glass catfish and tiger bards are good snacks.
Cheers Qwek

Cheers Qwek Uncle Qwek, we'll have to convert the tarpons if they are saltwater ones. we'll have to see how. thats 1, 2 is, where would we stock them? are they part of the freshwater eco system? any other fishes to stock? ka lui? sultan fish? grassie? patin? i will order more feeders soon as my fish seem to be more hungry than normal and the sebbies in my tank have shot up in size all of a sudden. they are more bold too, eating bigger prey than normal. when i order the feeders, i'll ask my feeder man what are the prices. Uncle Yu Hock, did you recieve Wei Yi's contact? Tight Lines & screaming reels An Ren

Hi YH,
How's the planting going? Had missed this thread for a while. Any lucks with the Lampam?
Hi An Ren, The tarpons can strive in brackish water, and the location I have in mind is idea for them to grow and there is an outlet for them to venture to the nearby sea. For your sebbies in your tanks I hope you have a good tank cover. If not the sebbies would one day like to see how long they can stay on your living room floor. Mine last only an afternoon, poor fellow.
Cheers Qwek

Cheers Qwek one became saltfish already... so have moved them into a larger tank with cover. i'll ask about the tarpons when i see my fish supplier again sometime soon. will ask him then. didnt speak much when i last saw him as i didnt know if u wanted brakish or FW tarpons.

Guys, Just returned from Kenyir. Nothing much - just some sebbies and tomans with plenty of good food (baung akar!) and company and scenery... hey.... it was fun! We are planning for another 6 nights (subject to all approval) trip on the week of National Day to reflect our patriotism while gobbling down top grade durian and pak suk kung and okay okay.... back to sebbies. We cannot back out the deal so $1.50 each it shall be. Next time round we shall try out An Ren new supplier. BTW, Indian Mahseer are available when I dropped by this evening. Not exactly our perfect IPO as it grows to 6feet and need the magnitude of Ganges River to spawn and play, but interesting to see a great sport fish in this tiny red dot. If only I have a tank that size.... Okay, anyone free next week to do the honour? Time will be 6:30pm meet at Serangoon. I need a car and 1 helper. Please put down your name and date available or PM me. Also, from the grapevine somebody caught sebbies in good numbers at one spawning ground. Hardly surprising as the rain of last 2 weeks reminded me that Sebbies should be spawning soon..... if anyone experienced it, I hope to have a large scale migration put in place. We need car and aerator for this. Please PM me for details. Thats all folks....in case I miss this - Happy Chinese New Year to all Chinese YH Happy Lunar New Year everyone! i was just thinking... if we get sebbies from 1 source, wont it be a rather limited gene pool as the fish may come from jus like 2 or 3 pairs of parens? i know nuts about breeding barbs... just what i wondered. inbreeding is something we don't want.

My outdoor observation at LSR during my recent home visit in Jan - Feb.
As we all know, LSR is flanked by two golf courses on each side of the reservoir. You have the OCC towards Yishun and SCC in the direction of Seletar Airport. I notice there has been a decrease in the growth of the weeds along the OCC banks during the third week of Jan to the first week of Feb. (The harvesting machines were operating at the Jetty, MRT track and SCC areas) And one of the 9 holes in OCC is in the process of "Renovation" as the fairway turfs were stripped off and covered with sand. In such instances, the maintenance of the fairway with fertilizers will not be carried out on a weekly basis. Could this be the reason?
Just as nitrogen acts as an excellent fertilizer for agricultural crops and golf turfs, it also acts as a fertilizer in aquatic ecosystems. When too much nitrogen is washed into a waterway from the golf courses due to rain and flow offs, it promotes an explosion of plant and algae growth, knocking the system out of balance.
The scum found on the water surface are algae and they are photosynthetic creatures. They are neither plant, animal or fungi. Algae releases oxygen into the water as it manufactures its food. The algae, bacteria and fungi use nitrogen as a nutrient and they grow quickly and become food for aquatic insects and fish. Then you have the dead gunk that falls to the bottom. That is converted by denitrifying bacteria back to a gas, which is vented back into the atmosphere. It forms the broad base on which the food pyramids in ponds and lakes is built. In manufacturing food, algae release oxygen, increasing the amount dissolved in the water.
However, when algae becomes overabundant the decaying algae depletes oxygen level. So when conditions for growing algae are ripe, oxygen levels may decrease, causing "Dead Zones" (where nothing can live) implicating the survival of the aquatic plants and fishes. I have seen a few dead Zebra fish of decent sizes floating along the banks of LSR due to this.
I see a resemblance of this at LPR, where SICC, with 4 golf courses, one of which runs along the opposite banks of LPR. A few years ago, LPR was infested with aquatic plants and algae where "Dead Zones" spot were sighted. Now you see LSR and LPR "harvesting" the aquatic plants on a daily basis to keep the system in check. But you don't see these harvesting been done at USR, MR, BR and PR. As for UPR and Kranji, in years to come...... it might need the harvesting as there are new golf courses opened along their banks just two years ago.
In my observation, so long as there are golf courses along the reservoirs, sometimes, the sudden explosion of aquatic plants and algae in our climate conditions ....... seems inevitable at times and I am sure PUB is working on this.
This is also happening in Clearwater......... they are now "trimming" the aquatic plants to keep the fishing lake in check.

Hi Huns, Very good observation and deduction. My friends and i were also discussing about the sudden dissapearance of weeds even in the areas near the legal grounds, along the mrt track and even the satellite area. Although we didn't thought that it could be due to the possible lack of fertilisers leaking into the reservoir. We thought it was due to the introduction of weed killers.
However, i feel that the creation of zones where nothing can live(anoxic zone) is not too possible as water is continuous exchanging particles with air and surrounding water to try to keep all conditions at equilibrium. Areas where the is totally no oxygen or at least to the point life perishes isn't to me possible in reservoirs. I have only heard of such zones in deep sand beds with at least 5-6 inches of fine sand with no water circulation at the top of the sand.
If the case is indeed as we thought, fertilisers from golf courses leaking into our reservoirs where we possibly get our drink from, isn't it even more detrimental than fly fishers or lurers fishing?
Will the PUB do something about it? Or rather can they do something about it? I don't know of any other ways that can counter fertilisers besides using other chemicals to nullify the potency of the fertilisers. But wouldn't adding more chemicals into our waters prove to be even more detrimetal? Besides stopping the the golf courses from using the fertilisers or continue the machanical way, i doubt there is other alternatives to this problem. Can someone share his/her views and enlighten us on this?

Hi there Anakin,
I hope I am wrong with the "Dead Zone" theory......... but occasionally the dead fishes found scattered at different spots with dense aquatic plants growth along the banks of the reservoir, does worry me. The other worrying point is, I don't see any weed shrimps feeding on the aquatic plants......... unlike a few years ago. Could it be that the Peacock bass are wiping them out? Or, could it be the water quality, as shrimps are known to thrives in clean water environment.
The amount of fertilizers from the golf courses seeping into our reservoirs should be within the PUB acceptable threshold level and I am sure the water quality is subjected to test every day.
This "Fertilizer theory" is just one of the many contributing factors leading to the infestation of the aquatic plants and algae.
Huns.

Hmmh.... something to think about! By the way have they collected all the funds for the sebies yet, or the sebies have been released? any idea?
