Question

what is the biological impact of minimum catch sizes on a population of fish? a. the population comes to be dominated by smaller, slower - growing individuals. b. older, less productive adults are removed, improving the population’s health. c. it applies a selective pressure for larger, faster growing fish. d. the fish in the population produce more and healthier eggs to compensate. please select the best answer from the choices provided

Explanation:

When minimum catch sizes are imposed, larger fish are more likely to be caught. This leaves smaller, slower - growing fish in the population to reproduce. Over time, the population will be dominated by these smaller, slower - growing individuals due to the selective pressure of the minimum catch size. Option b is incorrect as minimum catch sizes target larger fish, not necessarily older, less productive adults. Option c is the opposite of what happens. Option d has no direct relation to minimum catch sizes.

Answer:

A. The population comes to be dominated by smaller, slower - growing individuals.
