Prawn / Shrimp garden

Posted in Ideas at 14:23 by graham

People grow vegetables or fruit in their gardens, and may keep chickens or other animals. Indoors they may have a fish tank, but it is purely ornamental. How about an indoor Shrimp Garden ? An average sized fish tank should fit a good amount of shrimp. They are aggressive towards other fish, so you would keep them on their own. There must be a business in selling a tank with shrimp seeds and feed, exactly the way people sell tomato seeds and fertilizer – and you don’t need a garden to buy the tank !

Shrimp is a term used to describe about 2000 species of small aquatic animals related to crabs, lobsters, and crayfish. The site here might help pick a variety for growing indoors. Aquarium hobbyists keep shrimp to eat algae and detritus, but those species are not the eating kind.

They are already farmed commercially (see here) so it is possible and commercially viable – although they grow them in the sea / rivers rather than in tanks. They are even farmed organically. The genus they use is Macro-brachium. I saw a mention that they take about five months to grow up to eating size. The only question remains as to whether they can grow in a small aquarium.

Has anyone heard of this being done before ? Is there a good reason why this wouldn’t work ? What about crayfish ?

    Ive had a huge problem with snlais recently! I am new to the hobby and have not followed instructions on how to clean plants before planting. So a few eggs got thru and hatched. Before i knew it i had something like 150 snlais in the 90litre. However all my plants are as green and healthy as can be. Apparently they will only eat decaying plants and left over fish food. They usually stay away from healthy plants. My aim is to lower their numbers dramatically and keep them low.

    Hi all, I\’m aware of aquaculture (indoor farming of sea animals) being used to grow abalone in South Australia, this is commercially viable but not as profitable as open ocean farming of these animals as there is a bunch of time and energy spent on creating the right temperature and using UV lights to stimulate spawning and the like. So at the moment I\’d suggest its not a commercially viable option to farm shrimp which market for far less than abalone which are at $150/kg in places. So in summary: a hobby sure go for it, a business look elsewhere.

    Serious comment now:

    it’s a nice idea, but not commercially viable – at least not in a small aquarium. First, there is the temperature issue. Most edible shrimp come from cold waters, and cannot actually survive in warm water (where “warm” is the temperature a fishtank can reach in Europe during summer, say 22-25 C), and for technical reasons a fishtank cooler can easily cost 10 or 20 times more than a water warmer such as those sold with tropical fishtanks – this, among other things, is the reason why, for example, Mediterranean biotope fishtanks are so difficult and expensive to set up. On top of that, there is the oxygen density issue – on average, a fishtank can sustain 1 cm of fish per 30 sq. cm (1″ of fish per 12 square inches) of surface, meaning that, for example, to keep 3 bettas, each one 2 cm long, you need a fishtank with a free surface of at least 180 sq. cm. Even adding a bubbler or two, thus increasing the oxygen exchange with the atmosphere, and doubling the numbers due to the fact that crustaceans have lower oxygen requirements than fish, with a hobbyist’s fishtank you won’t go too far.

    A note: these numbers are for freswater fish and shrimps; salt water contains even less oxygen (and most edible shrimps come from the sea, not from rivers), so the density of the animals would have to be even lower

    Dear Sir

    my wife and I followed your advice and began breeding shrimps with the purpose of selling or eating them. Unfortunately, my wife could not bring herself to eat sweet little creature she had seen hatch and grow up and experience life, and feed from her hands.

    I am now the happy “adoptive father” of approx. 25.634.318 shrimp, and am considering the opportunity of suing you for damage under some wacky American law or other.

    You’ll hear from my lawyers

    Yours sincerely

    Possible. Too much work though. It’s best to corral them in an oceanside area.
