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~

Issue 83: Aquaponics Simplified | Hydroponics | Aquaponics~Aquaculture~Fish~Food | Scoop.it
July/August - 2005 Author: Wilson Lennard WILSON LENNARD outlines his research to develop a successful recirculating aquaponic system to produce Murray
Charlie Dare's insight:

Wilson Lennards findings~"

Our constant flow gravel bed system grows lettuce about 20% better than a reciprocal flow. Gravel beds and floating rafts are about 15-20% more efficient than NFT. My experiments have proven, within an aquaponic context, that NFT is less efficient at plant growth and nutrient stripping.

The last key finding is that we need to use a potassium and calcium-based buffer system. Fish farmers use sodium bicarbonate and similar basic salts to make sure the pH doesn’t drop. Fish systems are the opposite to hydroponic systems – as fish eat and metabolise feed, the water pH drops.

To counteract this pH drop, we use buffers to keep the pH up around 7. If we use potassium and calcium-based buffers, we can add the potassium and calcium to the system that the plants require for good growth.

KEY RESEARCH FINDINGS
So I had better tell you of the key findings. Fish (we used Murray Cod) and plants (we used lettuce) can be grown in an integrated aquaponic system. If the correct balance is met between plants and fish, no nutrient build-up occurs in the system, and the plants get all the nutrients they need."

Go with the constant flow is the go !
