Within the largemouth bass Micropterus salmoides sportfishin

Within the largemouth bass (Micropterus salmoides) sport-fishing industry, anglers selectively capture the largest individuals, which also tend to be the most reproductively successful males. Based on natural selection, what outcome might you predict to become more common over time?

Question 6 options:

Males will invest fewer resources in caring for their offspring

Males will reproduce at a smaller size

All of the answers are correct

Females will produce fewer eggs per breeding event

Fish will have a longer life span

Solution

b) Males will reproduce at a smaller size.

This can be justified by the fact that with selecting more and more number of large sized fish over a period of time, the larger size fishes will tend to reduce in number as compared to the smaller size fishes. Thus, the number of large sized fishes will reduce and males will appear reproduce at a smaller size.
