This page is an effort to compile lobster science information collected in LFA27. As more comes in it will certainly be added so be sure to check this page often.
David and Donald Ferguson, working for the DFO-FSRS Lobster Collector Project, have deployed 50 settlement collectors in False Bay to catch young-of-year (YOY) or 0-group lobsters. YOY are those that have settled to the bottom in late summer and early fall and are less than one year old. They have moulted beyond the postlarval stage (instar 4), so that by the end of the settlement season they are most likely in instar 5-7. These YOY lobsters have survived the vulnerable planktonic stage and have settled to those areas of the sea bottom where shelter is provided (e.g. cobble bottoms). The New England studies show that their settlement index predicts the abundance of lobsters several years later. The preliminary results are:
50 collectors were set on July 27, 2010 and retrieved on November 4, 2010. A total of 14 lobsters were retrieved: 9 YOY (<13 mm CL), 4 appear to be 1 year old and one lobster 2-3 years old (24mm CL).

NEW The new issue of Hook, Line and Thinker (Summer 2010) is available on-line. It is worth reading the whole issue, but the following articles I found quite interesting:
LFA27 Lobster Advisory Committee
The 2010 Science Report is now available! It comes in two files that you can download: The Science presentation and notes from the LFA27 Science committee. As soon as they are released by DFO Sydney office (hopefully by mid-May), we will post the minutes from the LFA27 Lobster Advisory Committee meeting of March 31st, 2010.
The Advisory Committee has a special meeting in the Spring where presentations are made by DFO scientists on data collected from the previous year. For 2009, the science report can be viewed or downloaded. Minutes from last years advisory meeting are also available: Minutes of the Lobster Advisory Committee meeting March 11, 2009. The Advisory Committee is meeting this year Wednesday, March 31st, 2010. 10:00 a.m. at the Membertou Trade and Convention Centre. All are welcome. For more information see our News page.
In 2004, a 2-day lobster science workshop was held at the Coast Guard college and was sponsored by the three main fishing groups located in LFA 27, The Maritimes Fishermen's Union Local #6, The North of Smokey Fishermen's Association, and The Eastern Cape Breton Fishermen's Association, in cooperation with The Department of Fisheries and Oceans. The minutes from that workshop were posted on MFU Local #6's website.
A lot of interested was expressed in tagging studies. From 1993 to 1995, 3684 lobsters were tagged off Cape Breton. The results indicate that 80% of tagged lobsters were recaptured within 6 km of their release site. View the report by clicking on Tagging Studies

More data results on Lobster in Eastern Cape Breton are presented in 2 DFO publications:
Stock Status Report 2004 and a research paper on the stock status and effects of an increase in the minimum legal size.
The Fishermen and Scientists Research Society (FSRS)
30 fishermen from LFA27 participate in FSRS's Lobster Recruitment Project. For a report on data up to 2008, see the Lobster Recruitment data. 2009 data will be available shortly.
For more detail on the project (design, participation, etc.) please see the following document: FSRS Lobster Recruitment Project
