OCEANSPHERE - NEXT GENERATION OF AQUACULTURE

Do tuna eat pizza if so go to Captains Pizza

New London CT try their Mushroom Garlic and Basil. yummy good for sushi too....

[mynameisbobilike2123]

where are you guys geting the food.... dont you guys need to take wiled fish to make them food... plzz tell me

@mynameisbobilike2123

Our fish are grown from eggs spawned in captivity. We do not catch wild immature tuna and grow them out. That is called ranching or catch and fatten which is very destructive to the fishery and why the North Atlantic Bluefin is under stress. We are a total egg to plate operation.

This is very interesting. However, doesn't balanced fish meal residue oxide once it hits the sea bottom and stays there for a few days? Another thing, i think i saw this technology being used already (or at least similar) somewhere in Puerto Rico isn't that right?

bspooner413, i'm curious on the size of the pens, what are the dimensions?

[stevey1111]

does the netting get fouled by seaweed? how to you prevent this?

[danich45]

wouldn't fish poop make good fertilizer for land crops

[bspooner413]

Fish poop is good in aquaponics, land based recirculation systems where vegetables are grown side-by-side fish. Tuna poop inour case will be mineralized by the large amounts of water we are in. 30% becomes calcium carbonate which helps counteract dissolved CO2.

hi bspooner413, i`m curious how much would it cost to buid Oceansphere?

[bspooner413]

I do not agree with your assumptions regarding patogen transfer. BTW CaCO3 in fish poop has been scientifically documented. We are not trying to solve the CO2 problem single handedly. The fact that there is CaCO3 in fish poop just helps demonstrate that claims about fish poop polluting the ocean are simply not true. As for the feed issue, wild tuna consume 15 pounds of wet forage fish per pound of growth. Properly balanced fish meal cuts that in half.

Interesting. You still won't solve the problem of wild fish coming in contact with farm fish (which potentially spreads pathogens between the two groups). Also, as the other poster asked, how would you feed the fish? Would you just rely on wild-caught fish as feed the way most aquaculture does today? (BTW, your claim that waste CaCO3 would somehow benefit the ocean is odd to me... Even if this claim is true, how many farms would you be building to create an ocean-wide impact??)

[greenboy215]

how much would it cost to build this huge system?

[lgd2007]

Seems like a good idea but.... how are you feeding them and is the waste just fouling the ocean floor?

[bspooner413]

The Oceansphere operates in deep ocean where currents are constant and large volume of water disperse effluent more efficiently than in bays, harbors and estuaries. Effluent will be absorbed naturally before ever hitting the bottom. Finally, a recent study published in Science shows that fish "poop" contains calcium carbonate which counters the acid created by dissolved CO2 in the ocean. We are looking at specially formulated algae and protein derived from ethanol waste product as feed.

wow thats awsome
