While all fish contain omega-3 fats, oily fish have the most. The best sources of healthy omega-3 fats include salmon, trout, sardines and anchovies. The next best include white tuna, mussels and ...
Most fish cannot live below 30% saturation since they rely on oxygen to derive energy from their nutrients. Hypoxia leads to impaired reproduction of remaining fish via endocrine disruption. [6] A "healthy" aquatic environment should seldom experience less than 80% saturation. The exaerobic zone is found at the boundary of anoxic and hypoxic zones.
In medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O. 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation ( (O. 2) sats) measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.
A fish's hypoxia tolerance can be represented in different ways. A commonly used representation is the critical O 2 tension (P crit), which is the lowest water O 2 tension (P O 2) at which a fish can maintain a stable O 2 consumption rate (M O 2). [2] A fish with a lower P crit is therefore thought to be more hypoxia-tolerant than a fish with a ...
Also known as suckermouth catfish, plecos are considered to be a good fish for beginners. Lovers of algae, these peaceful fish won’t demand any special water parameters to stay happy or healthy ...
On top of a quicker rate of diffusion in the respiratory system of southern bluefin tuna, there is a significant difference in the efficiency of the oxygen uptake. While other teleost fish typically utilize 27–50% of the oxygen in the water, the tuna's utilization rates have been observed as high as 50-60%.

Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1] If the level is below 90 percent, it is considered low and called hypoxemia . [ 2 ] Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.
