Question

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

Explanation:

Para determinar cómo los Ojibwe protegen las poblaciones de walleye, analizamos las opciones:

• La opción sobre pescar solo de noche no se relaciona con la protección de la población.
• Usar lanzas para capturar walleye es sobre la técnica de pesca, no protección.
• Contar huevos no es la forma en que protegen la población.
• Establecer un límite en el número y tamaño de walleye que un pescador con lanza puede capturar ayuda a regular la pesca y proteger la población, ya que evita la sobrepesca.

Answer:

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