Answer:
14.29%
Step-by-step explanation:
The death rate for that year will be the year percent decrease in the population of fish.
Initial population of fish = 7000fishes
Death of fish for the year = 1000fishes
death rate for the year = amount of death of fish for that year/initial population of fish × 100%
Yearly death rate = 1000/7000×100%
= 14.29%
