Final answer:
The total allowable catch of a marine fish used for human food is determined by calculating the maximum sustainable yield (MSY). MSY is the largest catch that can be taken from a fish stock over an indefinite period of time without depleting the stock.
Step-by-step explanation:
The total allowable catch of a marine fish used for human food is determined by calculating the maximum sustainable yield (MSY). MSY is the largest catch that can be taken from a fish stock over an indefinite period of time without depleting the stock. It is calculated based on factors such as the population size, growth rate, and natural mortality rate of the fish species.
