26591 Field Grow-out of Juvenile American Lobsters Data Set Published / External 23141 Aquaculture Systems & Ecology Branch (ASEB) Project Completed Early benthic stage American lobsters, Homarus americanus, were held in a pilot nursery system in Long Island Sound (LIS) to test field grow-out, as a step toward potential stock enhancement. A larger size upon release may increase the probability of survival. Lobsters were placed individually in perforated plastic mesh cylindrical "habitats" and each habitat was housed in an outer protective sleeve with a larger mesh size. During June 2013, twenty-four lobsters were transferred to each of 3 wire-mesh cages and deployed southwest of Charles Island in Milford, Connecticut (N=3). The only source of nutrition was naturally occurring organisms. Cages were retrieved monthly and lobsters were photographed to measure changes in carapace length (CL). After 11 months in the field, lobsters increased 92% in mean size from 6.0 to 11.6 mm CL, with 70.8 % overall survival. Head-starting of early benthic stage lobsters shows promise as a tool for possible future stock enhancement in LIS. Demonstration project to test feasibility of growing lobsters to a larger size in the field for potential release in enhancement studies. Mercaldo-Allen, R, Goldberg, R, Kuropat, C.

Lobsters are photographed in the field and these photos are used to measure carapace length back at the lab, using Image J software. Lobsters studies were conducted aboard the R/V Victor Loosanoff. Lobsters were reared in culture containers held in cages deployed in the field. Winches aboard the vessel were used to handle field gear. 32717 CL2013-14Alldates-NO restocks Published / External Completed Lobster carapace length measurements and calculations by sampling month over the 11-month study period Loaded by batch 8796, 05-16-2016 14:07 Spreadsheet Yes Lobster carapace length measurements and calculations by sampling month over the 11-month study period 1 Row_Identifier CHARACTER 200 Yes Yes Active For rows with individual lobster information, this column contains the identifier for the Lobster and Cage in the format "Cage Number,Lobster Number".
