DMR Larval Lobster Surveys

Lobsters hatch from eggs and develop through these four larval stages before settling on the sea floor.

Background:

The Maine Department of Marine Resources (DMR) began larval lobster surveys in the Midcoast region in 2018. This survey was implemented in collaboration with Dr. Eric Annis (Hood College) after a preliminary survey in 2017. This larval survey provides a point of comparison to historical work done in this area, and provides new biological datasets focused on this important lobster life stage.

Survey Objectives:

  1. Evaluate the abundance of larval lobsters in the Midcoast region (Zone E)
  2. Document the seasonal occurrence of larvae each year
