Question

how do the ojibwe protect walleye populations? 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. they count the total number of walleye eggs that a female lays each year. spearfishers can tell the difference between male walleye and female walleye by their size. males are slimmer. the ojibwe have fought hard to hold onto their rights to fish, hunt, trap, and gather on lands surrendered to the u.s. government in the 1800s. keeping these rights allows the ojibwe to continue their traditions of using natural resources. it also ensures that important cultural knowledge can be passed down to the next generation. and just like their ancestors, the ojibwe take only what they need.

Explanation:

The Ojibwe set limits on the number and size of walleye a spear - fisher can catch, which helps in sustainable fishing and protecting walleye populations. Using spears to catch walleye, fishing only at night, and counting walleye eggs do not directly relate to protecting populations as clearly as setting catch limits.

Answer:

They set a limit on the number and size of walleye a spear - fisher can catch.
