The
sampling designs used for cooperative resource surveys may range from traditional
stratified random sampling similar to resource surveys conducted on research
vessels to sentinel surveys where fisherman recommend sampling stations
based on their empirical knowledge. It is important that the partners in
the program understand that there are many variations in survey design,
many different designs have merit, and all designs have limitations.
- The Industry-Based Survey is a partnership between four New
England states (Maine, New Hampshire, Massachusetts, and Rhode Island);
NOAA Fisheries; and the fishing industry to collect data pertinent to
Gulf of Maine cod and Southern New England yellowtail flounder stocks.
The purpose of this program is for the fishing industry to assist in
providing higher-resolution data in near-shore areas.
- The focus of the Gulf of Maine Cod Assessment is to survey
aggregations of cod in time and space, describe cod distributions by
stock demographic characteristic (age structure, spawning, and variance),
and develop a species aggregation map. These surveys of cod distribution
are needed to monitor inshore stocks, assess the importance of these
areas as nursery and spawning grounds, and may provide greater detailed
information for management purposes. This program will be operational
in late 2003.
- The focus of the Southern New England Yellowtail Flounder Project
is to derive precise estimates of the abundance of Southern New England
yellowtail flounder at age using intense sampling with industry designed
"flatfish" trawls. Work on this project is currently underway.
