Regulations - Chapter 17
2
Regulations Tools to be used in conjunction with other management practices to achieve specific fishery goals and objectives
3
Types of Regulations Licenses/permits Provide revenue Survey database
Determine access to fishery
4
Types of Regulations Size limits
Minimum size - protect juvenile fish until maturity Maximum size - protect small stock of spawning fish
5
Types of Regulations Size limits
Slot limit - remove surplus of small fish, channel energy into medium-sized fish to help them get bigger faster
6
Types of Regulations Creel limits
Provide equitable division of harvest Catch and release - reduce fishing mortality Maintain high catch rates Increase catch of larger fish
7
Types of Regulations Seasons Closed to protect spawning fish
8
Types of Regulations Closed areas Protect anglers from danger
Protect fish in vulnerable habitats Spawning, nursery areas
9
Types of Regulations Gear restrictions
Promote diversity of “experience” Promote inefficiency of harvest Special implications often important Reduce hooking mortality
10
Differences Among Habitat Types
Coldwater fisheries Many regulations to protect from overexploitation
11
Differences Among Habitat Types
Coolwater, warmwater streams, rivers Seldom overexploited, regulations generally liberalized Exceptions: smallmouth bass, anadromous stocks (e.g., striped bass)
12
Differences Among Habitat Types
Lakes Regulations to prevent overharvest of top carnivores May be variable year-to-year Regulations now more common to reduce overexploitation of some prey (sunfish, perch)
13
Differences Among Habitat Types
Reservoirs Highly variable, liberal to restrictive Spatial zoning - different regulations in different areas
14
Basis for Regulations Regulations should be based on:
Biological relevance Public input
15
Future Direction Replacement of regional regulations by resource-specific regulations More difficult to understand More difficult to enforce More difficult to collect data needed to determine management needs for individual systems
