Nitrogen cycling in corals: the key to understanding holobiont functioning? Nils Rädecker, Claudia Pogoreutz, Christian R. Voolstra, Jörg Wiedenmann, Christian Wild Trends in Microbiology, Vol. 23, Issue 8, p490–497 http://dx.doi.org/10.1016/j.tim.2015.03.008 Nitrogen cycling in reef-building corals is a function of all holobiont members. Control of nitrogen cycling may stabilize holobiont functioning under oligotrophic and eutrophic conditions. […]

The response of the scleractinian coral Turbinaria reniformis to thermal stress depends on the nitrogen status of the coral holobiont
The response of the scleractinian coral Turbinaria reniformis to thermal stress depends on the nitrogen status of the coral holobiont Eric Béraud, François Gevaert, Cécile Rottier, Christine Ferrier-Pagès Journal of Experimental Biology 2013 216: 2665-2674; doi: 10.1242/jeb.085183 (Bolding is mine, for emphasis.) In non-stressed healthy corals, it has been shown that nutrient addition (nitrogen alone or in combination with phosphorus) may negatively impact […]
Velvet (Amyloodinium) infections in fish can easily be avoided.
“5. Conclusions
Our results indicate that infestations of […] the gill parasite A. ocellatum can be avoided if a defined pattern of water quality is kept within production ponds with a defined fish stocking level. This pattern of water quality can be achieved by water renewal with night tides, which should be carried out by considering the dissolved oxygen values in production ponds.”
What?
Velvet can be avoided.
It is not inevitable.
Even in a scenario where it’s commonplace.
How?
Stocking levels matter.
Water quality (not our definition*) matters.
This is something I (and others) have been stating for years — mostly against stiff opposition in social media forums. (Folks who generally see infections as inevitable and chemical treatments as mandatory….which they are if you don’t know or heed this info.)
The Assimilation of Diazotroph-Derived Nitrogen by Scleractinian Corals Depends on Their Metabolic Status
I knew that nitrogen-fixing microbes were a part of corals holobiont, but it’s not something I’ve read into before. This article was a great starter!
