Mr. Speaker, with regard to (a), scientific background information from peer-reviewed publications informed the decision on carapace size. See (b) below for a list of documents containing relevant scientific information and analyses. The key elements in achieving a healthy lobster fishery are good egg production, a reasonable fishing mortality, that is, the exploitation rate, and a biomass composed of several year classes. The lobster fishery in LFA 25 still operates under a regime of high exploitation rates greater than 50% and allows harvesting of up to 50% of immature females. In these circumstances, although lobster stocks have traditionally been quite resilient, there is still a risk of recruitment failure if the biomass is to change to a decreasing trend.
For long term healthy lobster populations that are resilient to natural population fluctuations, while supporting an active fishery with a high exploitation rate of greater than 50% percent every year, more female lobsters that produce eggs need to remain in the water. Increasing the carapace size would, therefore, have sustainability benefits in this fishing area.
With regard to (b), the following peer-reviewed scientific publications informed the decision on carapace size: 1, Comeau, M., and Savoie, F., 2002, “Maturity and reproduction cycle of the female American lobster, Homarus americanus, in the southwestern Gulf of St. Lawrence, Canada”, Journal of Crustacean Biology 22(4), pages 762-774; 2, Comeau, M., and LeBreton, M., 2012, “A bio-economic model for the lobster (Homarus americanus) fishery in Canada”, pages 273-295, in Kruse, G.H., H.I. Browman, K.L. Cochrane, D. Evans, G.S. Jamieson, P.A. Livingston, D. Woodby, and C.I. Zhang (eds.), Global Progress in Ecosystem-Based Fisheries Management, Alaska Sea Grant, University of Alaska Fairbanks, 396 pp., doi,10.4027/gpebfm.2012.014; 3, DFO, 2013, “American lobster, Homarus americanus, stock status in the southern Gulf of St. Lawrence: LFA 23, 24, 25, 26a and 26b”, DFO Can. Sci. Advis. Sec. Sci. Advis. Rep. 2013/029; 4, DFO, 2014, “Reference point options for the southern Gulf of St. Lawrence lobster stock (Lobster Fishing Areas 23, 24, 25, 26A, 26B)”, DFO Can. Sci.

Sci. Advis. Sec. Res. Doc. 2014/036, xii + 92 p.
A table of female maturity studies from 1994 to 2014 was also used as background science information, but is not yet published.
With regard to (c), numerous meetings over the last several years have been held on the carapace size issue, the latest being the Lobster Fishing Area 25 Management Committee Meeting held on April 14, 2016. The decision to increase the minimum lobster carapace size was made following lengthy consultations with a number of stakeholders, including the Prince Edward Island Fishermen’s Association, the Maritime Fishermen’s Union, the Gulf Nova Scotia Fishermen’s Coalition, first nations and aboriginal organizations, provincial representatives and processors from New Brunswick, Prince Edward Island, and Nova Scotia.
With regard to (d), the bio-economic model used in Comeau and LeBreton 2012 was specifically built for Lobster Fishing Area 25 and showed that in terms of the lobster population, an increase in the minimum legal size produced an increase in egg production. The model simulations of increased carapace size also resulted in an increase in the weighted average landings. Both 1 and 2 millimeter minimum legal size increases resulted in an increase in landings by year 2, with significant increases in landings up to 6 years after the initial size increase. The simulations also showed cumulative revenues becoming positive. Also, looking at other lobster fishing areas of the Southern Gulf of St. Lawrence where the minimum carapace size has increased in recent years, the economic and conservation benefits have been positive.
With regard to (e), the value of the lobster fishery in LFA 25 was over $56 million in 2015. The “canner” lobster represented 58% of this total. At 81 mm, lobsters are considered “market size” in all LFAs in the Gulf region. Even at a carapace size of 76 millimeters, the Prince Edward Island fishing industry would still have access to a portion of their catch as “canners” for their market.
