What’s the IQ of a fish?
However, we do know that IQ depends heavily on the species of fish. For instance, goldfish tend to be very unintelligent, with IQ’s measured in the 30-40 range, while some fish (such as freshwater salmon) have had IQ’s measured to be as high as 130. To put this in context, President Obama has an IQ of 125.

While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger.

Do fish get bored?
Most fish lead more behaviorally constrained lives–they don’t generally have as great a drive to investigate and interact with objects or areas in their environment, and thus don’t seem to generally get “bored” when such interactions aren’t available (caveats here because fish are incredibly diverse).
Do fish suffer when they are dying?
The process of chilling live fish as they suffocate is also likely to increase the severity of suffering and may also increase its duration. Until wild fish are killed humanely they should, at least, not be gutted or immersed in ice-slurry while they are still alive and conscious.
Why are sunfish so useless?
They included: the sunfish’s “useless” heavy body which can weigh up to 2,250kg (5,000 pounds), their lack of swim bladders (which fish generally need to control their buoyancy so that they don’t rise to the ocean’s surface), and the fact that they’re not even considered food by predators, which instead choose to chew …
