Re-read Section 7.3.4 in Regulating Harvest (Isermann and Paukert, 2010) and consider the following items.
- Differentiate between minimum, maximum, protected slot, and harvest slot length limits.
- What are typical possible responses of a fishery to the implementation of length limits?
- Describe population characteristics (density, growth, etc.) for when a protected slot or a harvest slot should be implemented.
Read The Role of Size Limits in Walleye Management (Brousseau and Armstrong (1987) and consider the following items.
- What are five potential objectives for implementing size limits on Walleye fisheries? Which is most common?
- Describe population characteristics (density, growth, etc.) for when a minimum, protected slot, or maximum length limit should be implemented.
- Explain why the author suggests that length limits should be applied on a lake-specific rather than state-wide basis. Why is this seldom followed in practice?
- List and describe factors that may create obstacles to the success of length limit regulations?
Read Managing Bass Fisheries with Size Limits (Allen) and consider the following items.
- What are the three factors that typically determine the success or failure of a length limit? Define each. Explain how each of these items may affect your determination to use one of the length limits or not? [For example, which of these items or combination of these items generally leads to a successful application of a protected slot length limit?]
- Describe how the author’s beliefs have about strict catch-and-release have changed over time.
- How has the strict catch-and-release ethic of most black bass anglers affected manager’s ability to manage fish poplations?
Read Weighing the Effects of Length Limits (Gangl, 2013) and consider the following items.
- What are the factors that typically determine the success or failure of a length limit? Explain how each of these items may affect your determination to use one of the length limits or not?
- What other considerations led the biologists to not implement length limits in the areas considered?
Read Bass Length Limits (Oklahoma Wildlife Department) and consider the following items.
- Compare “selective harvest” to “catch and release.”
- Describe population characteristics (density, growth, etc.) from when a minimum or protected slot should be implemented.
