Thought I'd share my semi-DIY project with you guys;

I've got a very very young octopus to sell. Not sure what species though.
Call 9862 7310

As a seafood farmer this is fascinating news. It tells us alot about the nutritional composition required for larval tuna. Or at the very least, where to begin experimenting. Nice =)

@Eniram: It's a 6000 litre system for the nursery and 3,210,000 litres for the grow-out systems. I'm not sure if that's financially viable...
@Magnet: Got the address? And is there any risk if I keep them with grouper, crabs, prawns and lobsters?
Was hoping some sort of tang would do the trick... Anyway, thanks guys.

Hey guys, our hatchery's been over-run with Green Slime Algae lately and it looks like even our milkfish(Chanos chanos) aren't eating it up anymore. Probably because they've gotten so fat on leftover fish food. So, does anyone know of another fish or shrimp we can use to clean our tanks?
-
There's a good chance that some of the byssal organ got ripped out with the fibrous threads. It which case it's likely your clam is bleeding to death. At least, that's what I know from working with mussels.
-
No worries, It's not like this is our main way of getting broodstock
Just offering those poor souls who bought giant grouper without realizing what they were, or baby sharks thinking that "they will somehow grow to the size of the tank", a way to get rid of their unwanted fish. Heck, if anyone's got giant Tridacnids they need to get rid of, I'd be happy to take them, we might be hooking up with some lecturers from NUS who're doing work with clams.
Would you mind sticky-ing this thread?

At the moment we're still laying the foundation for the farm, but here's some of the rough renders:

Greetings!
Just thought I'd let everyone know that my farm will be ready in the last quarter of 2011 and we're looking to adopt suitable Chondrichthyes, Serranidae and Lutjanidae(Sharks, Grouper and Snapper) you have that've gotten too big, as broodstock. These animals will NOT be sold as food, so you can be assured they'll live out the rest of their lives happily making babies. You may visit your former pets at the convenience of the farm staff, but keep in mind the animals no longer belongs to you.
Generally speaking, we will not be paying you for the animals, hence the "Adopt" in the title. This is because we have no way of knowing much of the animal's genetic traits since they've already spent most of their juvenile phase in your homes.
Note: We are looking for healthy individuals, those with severe physical deformities (except albinos) are not useful for breeding programs, however, if you would like a place for your pet to live out it's days in relative peace but are afraid of returning it to the wild due to said deformities, feel free to contact me, Shannon @ 9862 7310.

I vaguely remember posting photos of our attempts at liverock culture somewhere on the forums. As for open sea farming, Fuel is right, the water here is just too polluted to sustain any sort of reliable farm. But one needn't move inland to start a closed loop system.
-
Calibrated the refractometer, no change in salinity.
Acclimatized the invertibrates(flower crabs this time) with the drip method till the ratio was 4:1 Hatchery water : Old water, still no difference, they went through the strange shuddering motions 6 hours into the process and I had to pop them into the quarantine tank to revive them.
Completely at my wits end...
-
Hmm... I agree with you on the crustaceans, but what on earth killed the snails and worms? You'd think nerites would do fine in almost any conditions.
-
The soil is just aragonite.. is it possible that my water is lacking something instead of having something extra? Hmm...
-
Just got 2 copper test kits(for accuracy) from Aquamarin, it turns out I have NO copper in there at all. Is there any possible scenario where fish would survive but all invertibrates won't? I'm utterly stumped. Anyway, I've got some photos of the setup. Hopefully that gives you a clue as to what might be going wrong.
See the little milkfish in the corner? They've actually put on weight since we put them in.
New mangrove shoots in the sump.

Come on guys, any guesses? Do I need to make offerings to the sea god?

Hey guys,
We just set up a small 7000L hatchery and have been cycling the water for 2 months with sea lettuce and mangroves in the sump. 2 weeks ago we placed a few fish, crabs, prawns, worms, snails and a lobster in to test. All the invertibrates died within about 3 hours of being put in but the fish are fine and feeding. My guess is that there's copper in the water, here's what I've observed so far;
Crustaceans were lying on their sides after an hour and began twitching.
After 2 hours they were completely motionless except for the swimmerets which remained twitching.
Gills stopped moving after 3 - 4 hours.
Oddly enough, all the dead inverts tasted pretty damn good when we cooked them =D
So what are your thoughts?
Specs:
pH: 7.9
Salinity: 27ppt - Not a mistake, we're working with estuary species like Portunus pelagicus, Penaeus monodon, Lates calcarifer, Lutjanus argentimaculatus and Epinephelus lanceolatus and E. coioides
Temperature: 28ºC
gH: 80ppm
Nitrates: 0
Ammonia: 0
Flowrate 15,000L/hr

Many thanks for the directions guys, I'll just give it a few more weeks to see if some... mis-informed person has a big one that needs a new home. I remember reading on this forum about a guy who thought "Nature will somehow tell the fish when to stop growing".
-
Heya, I'm a kelong owner who's looking to adopt a shark that's outgrown it's tank. Get in touch with me if you know of such a person or if you have one yourself. We basically need a "guard dog" for our lobsters as well as something for people to look at.
You have my assurance that the shark will not be eaten of course =)
-
Heya Jerm, congratulations on the cuttlefish how's that tiny squid that got accidentally bagged as well? And for anyone who's interested, I'm the kelong guy
We'll be sponsoring the forum once we got all our odds and ends in order, most probably after CNY. For now, you can reach me at 98627310. We've got these cuttlefish, "bottlecap", "pencil" and "Green eyed"(I believe the old fishermen call them "Chang Mak") squid.
-
Heya, do post a shot of the cuttlefish once he's in =)

Strangely enough, No contamination from the shipyards in the form of heavy metals in our own tests. Iron content is slightly higher than expected though, probably because of all the welding and patch work that goes on at sembawang shipyard.
In fact if you wanted to verify, you can call AVA up, and as if oysters from the farm(Our neighbours) on the north coast of pulau ubin are safe for human consumption. They can be reached at 63257667.

Hi guys, I notice there's some misunderstanding going on.
If you'll take a look at my first post, we're 3 kilometers from the seagrass beds.
The rocks are suspended from the kelong, hence my only concern is that we're removing eggs or larvae that might attach to other objects further west. Which, as far as I know, don't exist since it's nothing but shipyards, industrial sites and powerplants.
And since there's nothing under the kelong but trash, beer bottles from the 60s and mud, there's no reef to damage.
Hope that clarifies things.
Anyway, so... what do you guys think is a reasonable price for uncured LRs? Especially considering most of us re-cure our rocks anyway
-
Interesting interesting... I shall take photos of my next sculpt. Ha! Learning fine arts came in handy after all!

@comycus: We're hanging artificially made rocks off our structure, the only things we "take" from the sea are whatever starts growing on/in our rocks.
@Zorden: If it makes you feel better, we ate an 8inch mantis shrimp last week
Was tasty 
@harlequin mania: Yup, exactly what I was thinking. This thing partly started as an attempt to increase the number of fish that lived in/around the farm. Then we put one in a tank and realized it looked alot like conventional LR. But personally I'm attracted to the nuisance critters
@FuEl: Alas there is hardly any clear water in Singapore. And we've got high nutrients and low calcium levels. SG dropped to 1.015 the other day, sample was taken from the bottom of a 2m deep cage.
So yes, we'll probably have to set up a large curing facility on the farm. But that means running the numbers again and getting another round of investors. Which i'm not sure is something we can afford, time wise. I'll explain more once we start sponsoring the forum. But in the meantime, could I get a show of hands as to how many of you would want a "sample" rock? They're small, about the size of a golfball, you'd have to pick them up yourselves from Changi Sailing Club.
Also, could you guys post what you think is a reasonable price for locally grown, uncured live rocks?

Oh! forgot to add photos!

DIY 200,000 Litre Pond
in DIY Forum
Posted
I think it's fair to say I cheated a little with the rented excavator and the fact that I run a small construction company
But yes, it's going to be a marine pond in a freehold property. It's incredibly cheap to build though, considering the volume.. cost under $30,000... a lot less than many of the big 8+ft tanks we see. And since I'm paying as i build, it's almost like I'm doing it in installments 
If any experienced engineers are cringing at the last picture of the brickwork; Yes, I know it's an ugly job, that's why it's in the DIY section
And my men were more interested in getting ready for Hari Raya than working in the hot sun.
