MPA Definition
Federal Definition MPA is a general term for places given special protections
for natural or historic marine resources by local, state, federal or tribal authorities national parks
• wildlife refuges• Monuments• marine sanctuaries• fisheries closures• critical habitat• habitat areas of particular concern• state parks,• conservation areas estuarine reserves and preserves

Fisheries management tools
Management tools for fisheries Quotas – how many Size limits – how big Gear restrictions – trawling prohibited within
shoreline to 3 mi Time based restrictions Spatially (place) based –
• Rockfish conservation areas• Cowcod conservation areas• Marine protected areas

California's MPAs - Marine Life Management Act
1999 - California State Legislature direct the state to design a network marine protected areas
MPA – six classifications State Marine Reserves
• No take State Marine Park
• Some recreational fishing allowed
State Marine Conservation Areas• Some recreational and
commercial fishing allowed

California's MPAs - Marine Life Management Act
Central Coast Project (Point Conception to Pigeon Point)
Proposed network of MPAs from Point Conception to Pigeon Point by 2006
Rest of the coast between 2006-2011
Public input critical!
Stakeholders (recreational angling and diving, commercial fishing, ports and harbors, conservation, business ) http://www.dfg.ca.gov/mrd/mlma/index.html

California’s Fisheries
Pacific Fisheries Information Network (PacFin)
Fishery catch reported by the commercial industry
• Landings (lbs)• Species• Year• Location (10 nm
blocks)
http://www.psmfc.org/pacfin/overview.html

Your mission is to select MPAs that consists 1 and 2 contiguous fishing blocks that:
Have a depth equal to or less than 1200 m The bottom substrate is either hard or
mixed Is more than 25 nautical miles from Moss
Landing and Morro Bay Will not heavily impact fishers

Merge
Combines input features from multiple input sources (of the same data type) into a single, new, output feature class. The input data sources may be point, line, or polygon feature classes or tables.

Intersect This tool builds a new feature class from the
intersecting features common in both feature classes. It retains the attributes of both feature classes.
Analysis Tools> Overlay > Intersect

Clip This tool uses a polygon boundary to cut features
and their attributes from a feature class.
Works like a cookie cutter.
Analysis Tools> Extract > Clip

Buffer
This tool creates a new feature class of buffer polygons around either polygon, line, or point features.
Analysis Tools> Proximity > Buffer

Dissolve
This tool combines like features based on a specified attribute or attributes.
