“…It also showed patchiness in benthic recruitment of lobster at the spatial scale of 0.4-4 km 2 in the southwest Bay of Fundy (Sigurdsson et al 2016), and preliminary analyses indicate that this patchiness is most strongly related to variation in the North Atlantic Oscillation Index and the abundance of juvenile lobsters.…”

Abstract:In 2010, more than 20 associations representing harvesters from five provinces bordering the range of American lobster (Homarus americanus) in Canada, from the Gulf of Maine to southern Labrador, joined government research scientists at Fisheries and Oceans Canada (and one provincial department) and researchers from Canadian universities (two English-and four French-speaking) to establish the Lobster Node. This partnership was formed to address knowledge gaps on lobster productivity, stock structure, and connectivity through collaborative research under the auspices of the Canadian Fisheries Research Network (CFRN), which was funded by the Natural Sciences and Engineering Research Council of Canada. In so doing, the research partners overcame barriers of geography, language, culture, education, and, in some cases, longstanding disputes around management and conservation measures. This paper reviews why and how the Lobster Node was formed, what it achieved scientifically, what benefits (and challenges) it provided to the partners, and why it succeeded. It concludes by advocating for the creation of a permanent collaborative platform to conduct research in support of lobster fisheries in Canada.Résumé : En 2010, plus de 20 associations représentant des pêcheurs de cinq provinces bordant l'aire de distribution du homard Américain (Homarus americanus) au Canada, du Golfe du Maine au sud du Labrador, se sont joints à des chercheurs gouvernementaux au Ministère des Pêches et Océans Canada (et un ministère provincial) et des chercheurs d'universités canadiennes (deux anglophones et quatre francophones) pour établir le Groupe Homard. Ce partenariat fut formé afin de combler des lacunes de connaissances au niveau de la productivité, de la structure et de la connectivité des stocks de homard par l'entremise de recherche collaborative sous les auspices du Réseau canadien de recherche sur la pêche (RCRP), financé par le Conseil de recherches en sciences naturelles et en génie du Canada. Ce faisant, les partenaires ont dû surmonter des obstacles liés à la géographie, la langue, la culture, l'éducation et, dans certains cas, des différends historiques autour des mesures de gestion et de conservation. Cet article explique pourquoi et comment le Groupe Homard a été formé, ce qu'il a accompli scientifiquement, quels avantages (et défis) il a donnés aux partenaires, et pourquoi cette initiative fut couronnée de succès. Nous concluons en plaidant pour la création d'une plate-forme collaborative permanente pour mener des recherches en appui à la pêche au homard au Canada.

“…The relevance of the variables depth and distance from shore to YOY stone crab relative abundance also was complex and varied greatly among locations. Along the Gulf Coast, stations in water less than approximately 4.5 m deep were located either within recruitment "hotspots" (Cedar Key, Everglades Offshore) or "coldspots" (St. Marks and Homosassa) (Morgan et al 2011, Groeneveld et al 2012, Sigurdsson et al 2016. At depths greater than or equal to 4.5 m, the linear decrease in relative abundance as water depth increased may have been due to decreasing YOY stone crab recruitment as distance from shallow-water recruitment hot spots increased.…”

“…The resulting time series have become a springboard for subsequent studies addressing a variety of research questions, especially regarding the processes operating before and after larval settlement to influence the fate of a cohort between the time of hatching and recruitment to the fishery. They include oceanographic drivers of lobster larval transport, pelagic-benthic coupling, the effect of substrate quality on postlarval settlement, spatial scale of settlement patchiness, cobble nursery community structure, settler-recruit dynamics, disease impacts, crustacean sampling designs, and forecasting commercial harvest (Incze et al, 1997;Butler et al, 2006;Steneck and Wahle, 2013;Sigurdsson et al, 2014;Ellis et al, 2015;Sigurdsson et al, 2016;Hunt et al, 2017;Goode et al, 2019;Oppenheim et al, 2019;White, 2022). The scientific questions addressed with this program have been critical to understanding the sustainability of the resource, which has become particularly important with the expansion of the lobster fishery over the past decade.…”

Understanding the processes that influence recruitment variability in marine populations has been a long-standing challenge for resource management. Quantifying abundance at early life stages for marine fish and invertebrates with complex life histories can be difficult and require unconventional sampling approaches. However, the benefit of developing appropriate tools to sample early life stages is that, together with associated demographic and environmental information, the data can provide insights into the causes and consequences of recruitment variability, allowing prediction of older life stage abundance. Before the 1980s, the earliest benthic life stages of the American lobster (Homarus americanus) eluded quantitative field surveys. With the development of diver-based and vessel-deployed sampling methods over the past three decades, the American Lobster Settlement Index (ALSI) program has expanded into a regional, transboundary commitment to better understand lobster settlement processes and forecast future fishery trends for what has become the most valuable single-species fishery in North America. In this context, “settlement” is a shorthand for the annual recruitment of young-of-year lobster to coastal nurseries, as postlarvae settle to the seabed at the end of larval development. Here, we review the development and products of the ALSI program, first outlining the goals, methods, and data products of the program. We then highlight how the program has advanced the scientific knowledge on pre- and post-settlement processes that influence the fate of a cohort from egg hatch to harvest, which provides insight into the spawner-recruit relationship. Lastly, we provide guidance for future research recommendations building on the ALSI science to-date, some major elements of the program that have allowed for its success, and considerations for maintaining the ALSI program. By highlighting the uniqueness and contributions of the ALSI program, we hope it serves as a model for other scientists, managers, and industry collaborators aiming to understand recruitment processes for species over a broad geographic area.
