I am searching for an organism that is also easy to breed in the aquarium and reproduces relatively quickly (say up to 2 or 3 months is ok). I am open to both salt- and freshwater organisms!
I would investigate organisms from the Red Sea or the Persian Gulf. Many are adapted to extremes of both temperature and salinity.
Hi Martin,
Some studies in canadian waters are looking at American lobster juveniles and also shrimp species.
Cheers,

I have had great results with Corophium volutator. Its small, reproduces easily, easy to identify gender as well as reproductive status. Moreover, its relationship to various temperature, salinity, and pH variables has been investigated before.
Ive had great results with mussid coral. Easy to isolate polyps, very sensitive.
Hi Martin,
Most of marine organisms are really sensitive to that environmental factors although the effects would change depending on the species, region, magnitude of the effect, .... So, depend on your interest of your research, you can choose one or other.
In general, bivalves such as mussels and oysters are good candidates for the acidification effects due to alteration in the shell formation. But acidification also modify skeletogenesis or otolith in fish larvae, among others. Basically, main structures based on calcium carbonate are susceptible to be affected by acidification
With respect the temperature, its effects on marine organisms are really very diverse affecting metabolism, welfare or even genomic imprinting.
So, you will have a high spectrum of possibilities to do your research
Cheers,
Manuel
Hello Martin! I agree with Kantha Rajan. I would try with plankton organisms; they can be cultured in the lab and as Kantha said, they have short life cycle, so you could set an experiment for around 20 o 30 days (depending on the question you want to answer) and you can have interesting results.
Cheers!
I agree with Ana and Kantha. I would also suggest larval stages (pelagic stages) of species such as lobsters, carbs and bivalves which are really sensitive to acidification (decalcification etc..) Cheers,
Molluscan organisms for acidification and corals for temperature change
