We used the American lobster (Homarus americanus) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field. We assessed and compared the thermal tolerances of larvae in the laboratory and to link to patterns in the field we measured larval settlement as a function of depth (and therefore temperatures) and deployed caged larvae at different depths (...
Show more180 Larval settlement collectors were deployed for the 2023 larval season to quantify settlement as a function of depth and temperature. Each collector was a 0.55 m2 rectangular cage with 0.15 m high sides filled with cobble stone (< 20 cm diameter). The wire mesh bottom of the cage was lined with 3 mm plastic mesh to retain newly settled lobsters on retrieval. Each collector had a temperature logger attached to the top to record bottom temperature for the duration of the deployment. The collectors were deployed in pairs with a single buoy and line to the surface. Collectors were deployed in the first week of June and retrieved in the last week of September.
