You would measure weight.
That would be weight.
The spring balance with 0-10 newton has a soft spring that would extend lightly but the spring balance that measures forces up to 500 newton has a hard spring that would extend slowly.

If the fish does not struggle (it would have to be dead not to) and above water, then you can measure a spring scale.
A Tubular Spring scale.
In a modern lab, you would use a digital scale to measure mass. Historically, balances and spring scales were used.

You could measure weight with a spring scale, unless you mean mass, which you would measure with a laboratory balance. You would measure time with a stop watch, and height with a meter stick.

A spring scale measures weight. It is dependent on the gravity, and so one's weight in space, or on the moon would be different based on the spring scale. A balance measures mass, and since the standards in a balance are the same no matter what the gravity is, then the mass remains constant. However, for all practical purposes, the gravity on earth is constant so the weight and mass of the objects would be the same.

It would work the same, but measure the same mass as different weights depending on the planet. On the gas giants it would be hard to find a place to set it.
