Navigating towards Decoupled Aquaponic Systems: A System Dynamics Design Approach

Navigating towards Decoupled Aquaponic Systems: A System Dynamics Design Approach | Aquaponics~Aquaculture~Fish~Food | Scoop.it
The classical working principle of aquaponics is to provide nutrient-rich aquacultural water to a hydroponic plant culture unit, which in turn depurates the water that is returned to the aquaculture tanks.

Charlie Dare's insight:
If you are handy, you can build your own tank out of plywood using sealants and/or a pond liner. You can get creative with materials and with designs. John Kohler, of Growing Your Greens, gives us a walkthrough on a sweet DIY fish tank on his Youtube channel. This tank was built using just 2x4 lumber and a special seamless coating. Tune in at minute 15:30 to get right to the DIY goodness. There may be a size limit to how big you can build using your own materials. You may choose a long, trough like design to help keep things manageable. The difficulty is to build a large enough tank while eliminating leaks and weak points.

Charlie Dare's insight:

Their comment is comprehensive ~Omega-3s are essential nutrients found in fresh, Australian JADE Perch a fish also suitable for RAS unlike their cousins Silver Perch having highest Omega-3 content of any farmed species~ They say... "The fish in this Aquaponic system are Jade Perch which are about 9 months old. Jade Perch have quite a small mouth and once they have reached a size larger than 10cm or 4 inches they are not considered to be cannibalistic. They are omnivorous fish, which means they require both protein and plant material in their diet.
The plant part of these Jade Perch's diet consists of lettuce, spinach and wheat grass which all grow very well in the Aquaponic system and wicking beds. They absolutely love these young lettuce leaves so much so that they will leap out of the water to get at them!
This is a great, cheap, healthy, fun way to feed your fish and also helps satisfy part of their dietary requirements.
The aim is to experimentally grow and feed these fish home grown foods only (no fish pellets that cost extra money) such as lettuce, spinach and wheat grass and monitor their progress. "

Nitrate Levels in Aquaculture May Be More Dangerous Than You Think

Nitrate Levels in Aquaculture May Be More Dangerous Than You Think | Aquaponics~Aquaculture~Fish~Food | Scoop.it

Modest levels of nitrate nitrogen – in the 75 to 100 mg/L range – may be more harmful to aquaculture-raised rainbow trout than producers realize. A team of scientists at the Conservation Fund’s Freshwater Institute led by John Davidson documented deformities and significant behavioral changes in rainbow trout (Oncorhynchus mykiss) raised in recirculating aquaculture systems (RAS) with nitrate nitrogen concentrations at levels less than one-tenth the recommended maximum nitrate nitrogen level of 1,000 mg/L. They believe the changes were spurred by chronic exposure to nitrate nitrogen.

Human ARF Gene Prevents Zebrafish Regeneration

Human ARF Gene Prevents Zebrafish Regeneration | Aquaponics~Aquaculture~Fish~Food | Scoop.it

Regenerative medicine could one day allow physicians to correct congenital deformities, regrow damaged fingers, or even mend a broken heart. But to do it, they will have to reckon with the body’s own anti-cancer security system. Now UCSF researchers have found a human gene that may be a key mediator of this trade-off, blocking both tumors and healthy regeneration.


As a child, UCSF’s Jason Pomerantz, MD, was amazed by the fact that salamanders can regenerate limbs. Now, as a plastic surgeon and stem cell researcher, he believes that insights from creatures like zebrafish and salamanders, which routinely regrow damaged tails, limbs, jaws and even hearts, may one day endow humans with heightened regenerative abilities.


“In the last 10 to 15 years, as regenerative organisms like zebrafish have become genetically tractable to study in the lab, I became convinced that these animals might be able to teach us what is possible for human regeneration,” Pomerantz said. “Why can these vertebrates regenerate highly complex structures, while we can’t?”


In a study published Nov. 17, 2015, in the journal eLife, Pomerantz and his team showed new evidence suggesting that mammals may have given up the ability to regenerate limbs partly in exchange for advanced cancer-fighting genes.


The question of whether the regenerative powers of zebrafish and salamanders represent ancient abilities that mammals have lost, perhaps in exchange for advanced tumor-suppression systems remains an open question for biologists. Most tumor suppressor genes, being extremely useful for preventing cancer and for forming tissues during development, are broadly distributed and conserved across many different species. Recent studies, however, suggest that one, the Arf gene, arose more recently in the avian and mammalian lineage, and has no equivalent in the genomes of highly regenerative animals.


To explore whether this gene might play a role in preventing tissue regeneration in humans, the researchers added human ARF to the zebrafish genome and assessed how it affected the fishes’ normal ability to regrow damaged fins after injury. They found that human ARF had no effect on the fishes’ normal development or response to superficial injury, but when the researchers trimmed off the tip of a fish’s tail fin, the gene became strongly activated and almost completely prevented fin regrowth by activating a conserved tumor-blocking pathway.


“It’s like the gene is mistaking the regenerating fin cells for aspiring cancer cells,” said Pomerantz, who is an associate professor of plastic and reconstructive surgery at UCSF and surgical director of the Craniofacial Center at UCSF’s Medical Center and School of Dentistry. “And so it springs into action to block it.”

It’s remarkable that ARF can so readily integrate itself into the fish’s existing tumor-blocking pathways, Pomerantz said.

Charlie Dare's insight:

Another valuable course for those involved in growing fish as water quality is particularly important for growing species like Trout.Taste of fish also is a big factor between getting a decent price or ruining the reputation of a species for all those that taste/waste money on a off flavoured fish~ This happened at function at Sydney Fish Market giving away samples to visitors who deposited the free samples in the nearest bin, never to buy again.I not mention the species because more reputable growers purge their stock to rid the off flavour~

The most common off-flavour compounds found in cultivated fish are 2-Methylisoborneol (2-MIB) and geosmin (GSM), which are secondary a blue green algae~Rapidly taken up by gills of fish (hrs) but days of purging with a slight weight loss with out feed make them much more palatable.I,ve added salt to fresh water too as it acts as a prophylactic to help stressed fish from getting other fungal/disease problems~

Sizing a Pump for Aquaponics or Hydroponics

Sizing a Pump for Aquaponics or Hydroponics | Aquaponics~Aquaculture~Fish~Food | Scoop.it
There are 3 steps to sizing a pump for aquaponics or hydroponics: calculate GPH (using the formula here), measure head height, and combine using the chart.
Charlie Dare's insight:
For an efficient system you need the right sized pumps with a bit more capacity than you,ve measured in volume and head.Flow meters can also be useful to increase flow for species like trout that have a high oxygen requirement.Handy to have a DO(Dissolved Oxygen) meter if any number of fish.I havn`t bought from this site and found YouTube videos saying fence post covers are a fraction of the price this group sells similar as vertical towers. I`m merely picking out useful information from various Aquaponics supply marketers not endorsing one over another or theirs systems~ I believe an integrated system has overall benefits.Increasing the amount of vegetables grown as some root types,tomatoes fruiting types, grow better in a medium ,while others,leafy (lettuce ) are suitable for towers or rafts like Kale a good one in them ~
