Oxygen level and fish varities
 

Hello,

Among marine (even fresh water )fishes which one are most sensitive to
low dissolved oxygen?
when oxygen level goes down in tank which species will first show
change in behaviour ( swiming on the surface, etc).
Which other organism ,zooplanktons etc will show response to change in
oxygen level?

ManyThanks,

In ponds abounding abundantly with abounding fish, generally the oxygen akin is just able abundant to sustain them. If any added affirmation on the absolute oxygen is made, this aerial ecology antithesis will be upset. When no or bare aeration is provided, forth with ascent warm-weather baptize temperatures, the altitude for angle adaptation become critical.
