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

The correct option is E. 
The minimum catch size is the smallest allowed length for a caught fish. The lengths of fish are measured from the tip of the jaw to the tail fin. The laws that enforced minimum catch size are aimed at increasing the protection of some fish species and to promote sustainable fishing. 
The minimum catch size allowed the fishers to take out the adults fishes while those that are smaller are left behind, this allows the population of fish in the water to be dominated by smaller, slower growing fishes.
