Question

how do the ojibwe protect walleye populations? they count the total number of walleye eggs that a female lays each year. they set a limit on the number and size of walleye a spearfisher can catch. they use spears to catch walleye. they only fish for walleye at night.

Explanation:

To determine how the Ojibwe protect walleye populations, we analyze each option:

• The first option (counting walleye eggs) is more about studying reproduction, not direct protection.
• The second option (setting a limit on the number and size of walleye a spearfisher can catch) is a management strategy to prevent overfishing, which directly protects the population.
• The third option (using spears to catch walleye) describes a fishing method, not a protection method.
• The fourth option (fishing at night) is a fishing practice, not a protection measure.

Answer:

B. They set a limit on the number and size of walleye a spearfisher can catch.
