Researchers want to know how overfishing is impacting fish populations to make decisions about whether new policies are needed to protect fish populations. what empirical evidence could be collected to get an idea of how overfishing is affecting particular populations? scientists could measure the amount of bycatch. scientists could measure the amount of money collected by fishermen. scientists could measure the level of animal waste in the water. scientists could measure the number of fishermen on the water.

A. scientists could measure the amount of bycatch

Explanation:

Scientists could measure the amount of by catch.

Explanation:

Overfishing is the process of fishing in which a considerable number of fish species are removed from the water body at a rate that the population of such species cannot be replenished for a long period of time. This results in the decline in the population of the fish species, or extinction of the species. This can lead to the loss of biodiversity.

If the researchers wants to the impact of the overfishing they could measure the amount of by-catch. As the by-catch over the expected or standard limits can lead to the decrease in the fish population belonging to a particular species. This may lead to the extinction of many fish species.
