New England Lobster Settlement Index
Listed in NASA Earthdata CMR
The New England lobster settlement index is a sampling program supported by Maine, Rhode Island, and Massachusetts.
Description
The goal of the program is to evaluate the strength of lobster year classes as they first arrive by larval settlement in shallow, nearshore nurseries. The information obtained from the research can then be used in stock assessment, and in forecasting trends in the fishery.

Methods
Divers from Bigelow Laboratory employ a suction sampler to collect newly-settled lobsters. Cryptic in behavior at this stage, juvenile lobsters prefer to settle in shelter-providing cobble-boulder habitats. The suction samples are sorted in the laboratory for young -of-year lobsters, about an inch (2.5cm) in total length.
In their first year, lobsters grow slightly larger in the southern part of their range than in the colder waters to the north. Thus, it takes lobsters in Rhode Island 4-5 years to reach harvestable size, whereas it can take up to 9 years for lobsters in the colder Gulf of Maine. Number of Samples Collected: 12 quadrats per site
