Who wants to breed Tuna?

Sounds like we need a really big pool, some tuna, and a chemist to make some synthetic hormones.

I imagine there are untold fortunes in aquacultured tuna but the sheer scale needed to make a dent in the fishing industry is mind boggling.

One of the articles also brought up a good point. What are you going to feed them without taking another fish out of the ocean.
 
The hormones are already commercially available, not cheap, but they are out there to buy.
 
Well there you go major hurdle outta the way. My buddy has a saltwater swimming pool. Whos got a line on some live blue fin tuna?

Read the ingredient list ;) The best pellet foods like NSL or Othohim are heavy in the good marine based foods such as fish :) I wouldn't use them otherwise :D

Soy and polychaetes are bring used in a big way now for AC feeds. Soy more so and for longer. Companies like Dragon Feeds and Aqua Thrive are pushing the polychaete feeds w/ sustainable fish meal (fish meal scraps from processing plants doing food meant for human consumption)
 
There is a commercial research outfit in either Australia or New Zealand that has already gotten courting behavior & sperm release from males in a captive system by manipulating light cycles and temp.
 
tuna eat crustaceans too!!!it doesn't have to be fish based. their are plenty of crustaceans in the oceans that are currently under fished. (such a wierd term). take krill.

you could also have a shrimp farm fed by algae to feed the tuna. if you plan it out right you could use the algae as a means of making it a green aquaculture facility (I.E. sequestering and removing more co2 from the environment than whats used to run the joint)
 
Fish farming......especially tuna in sea-pens.....and the term "green" just don't go together. Look up the environmental controversy surrounding shrimp culture and salmon culture.....watch out!!!!

Lots of money available if ultimately successful!!!!!

Krill has heavy pressure on it in some seas. It's the next issue, and some governments are all ready looking into stopping the fishery. The US all ready has taken steps to stop it in their waters.

FWIW at a local Asian market, Krill products take up most the fish section. Pound for pound they stock more Krill then fish.
 
Gresh is right on. There's been talk of krill overfishing in fisheries circles for over 20 years that I know of. Not only is krill heavily fished, but it's the main food source for a large number of commercial finfish species as well as whales. This means overfishing krill has much larger and broader reaching implications than just a drop in krill populations.

I stand thuroughly corrected.

I remember reading that krill was unsuitable for commercial fishing because it would be worth little and is spread out over vast distances. from this i made the assumption that they weren't overfished. I need to remember what happens when one assumes lol a s s out of u and me
 
Krill can be found in quite large concentrations, especially at night. I've seen bands of krill at depth so thick that the depth sounder shows them as solid bottom. They also smell really, really bad when they hit the deck :eek2: But you also find lots of cool stuff mixed in, larval lobsters, fish etc, makes the stench worth putting up with :D
