Gallons per fish: does a sweet spot exist?

Started this discussion. Last reply by TCLynx Sep 5, 2010. 21 Replies 0 Likes

I heard a rule of thumb recently that you don't want to go much more dense than 4 or 5 gallons per full-grown fish. I assume this has something to do with the amount of nitrifying bacteria available…Continue

I'm not in Denver, but not too far from there (Colorado Springs). I have a fairly new system. I started plants about a month ago and just got my fish (trout) yesterday. Here's a link to the blog I've started,…

I'll do it. I'm a beginer with 2, very little, 27 gallon systems, raising goldfish, tomatoes, chilli peppers, strawberries a snap pea, some cilantro and ...I think that's it. Oh an apple tree sprouted too plus hundreds of…

I can document my AP experiences. I am a complete beginer without a clue.

How did you know where to mark the gallon lines on your tank?

I am going to document the buidling and implementation of my system starting this weekend. I don't live in metro Denver, but I would be happy to give a southern Colorado prospective if you want.

HI Ken, I'm just a rookie but check out out the system I've built during the last week.Its being constructed and tested in Louisville, then sometime in the future will get moved up to the mountains.

JD, thanks for opening up at the GrowHaus. The session was certainly informative, and I look forward to seeing who attends your class on the 20th.

Great idea, Ken! What is the online site?

I'm certainly interested and have already posted some pics and videos on this site as well as on my own website at www.coloradoaquaponics.com. It would be great to have you stop by for a visit to the GrowHaus in the near future. JD

Care to show off your system?

I'd like to start documenting the progress of who's doing aquaponics and hydroponics in the Denver Metro area. Pictures, questions, perhaps video (after I work up the $). The results will be posted in an online newsletter/magazine. Is anybody interested?See More

Always happy to help. Too many fish is more often a problem in backyard system than not enough. There are many people that run huge amounts of Veggies just with some goldfish so don't feel that you need to have a large number of tilapia in…

Thank you again This all helps to clarify my dilemma, which thanks to you is not a dilemma any more. Appreciate the help. John

TCLynx replied to Ken Westervelt's discussion 'Gallons per fish: does a sweet spot exist?'

I think your numbers of 1lb fish per amount of grow bed might be a little high. For a recommended stocking density of a backyard system wanting to produce edible fish, 1 fish per cubic foot of media (assuming growing out to 1 lb) is a good…

John Lang replied to Ken Westervelt's discussion 'Gallons per fish: does a sweet spot exist?'

Thanks for the info TCLynx I am thinking of just expanding on the barrel idea for grow beds, so 100 sq ft surface using 1/2 barrels (not 100 cu ft) I believe calculates to around 60 cu ft of media or around 450 gal of media.This would bring the fish…

How many fish to a school?

Posted on August 5, 2010 at 12:11pm 5 Comments 0 Likes

I am far from an expert on the aquarium side of aquaponics. There are certain kinds of tasty freshwater fish that school together. Arctic char, for instance. The problem is, I don't have a clue as to how many fingerlings I would need to get before they clump together and act like a school of fish.

This will probably not be my first tank I build, but it's good to know what options are out there.

Worms to replace 'trash fish' feed?

Posted on June 17, 2010 at 7:00am 2 Comments 0 Likes

Tuna, salmon, eel, and other carnivorous fish are fed ground-up fish meal. Many think this is an unsustainable practice. Every pound of meat-eating fish requires between two and twenty pounds of fish meal. This continues the drain on our ocean life. Alternatives can and should be looked into.

One protein source is readily available, and currently being used in many areas around the world. Composting earthworms have potential as a substitute. These worms feed on vegetable scraps, wood,… Continue

Please fill out the survey that is linked to on the home page, and at the end I'm looking for people to help with this. Given how small aquaponics still is in the US, I'm hoping for 20 people at this...but everything starts somewhere, right?

Thanks for the offer!
