“…For instance, the economic value of this industry is directly related to our ability to maximize key traits in our cultivars (Kim et al. ): food quality, chemical concentrations, growth rates, morphology, etc. These desired traits are, in turn, regulated through application of basic evolutionary approaches, like strain selection, controlled breeding, site‐selection (both for operations and for collection of appropriate genotypes/phenotypes), and so on (see Valero et al.…”

Documenting the causes and consequences of intraspecific variation forms the foundation of much of evolutionary ecology. In this Perspectives piece, we review the importance of individual variation in ecology and evolution, argue that contemporary phycology often overlooks this foundational biological unit, and highlight how this lack of attention has potentially constrained our understanding of seaweeds. We then provide some suggestions of promising but underrepresented approaches, for instance: conducting more studies and analyses at the level of the individual; designing studies to evaluate heritability and genetic regulation of traits; and measuring associations between individual variation in functional traits and ecological outcomes. We close by highlighting areas of phycological research (e.g., population biology, ecology, aquaculture, climate change management) that could benefit immediately from including a focus on individual variation. Algae, for their part, provide us with a powerful and diverse set of ecological and evolutionary traits to explore these topics. There is much to be discovered.

“…While many of these studies were conducted in Europe, sugar kelp aquaculture has also been investigated in both Canada and the USA (Brinkhuis et al 1984; Troell et al 2009; Redmond et al 2014; Kim et al 2015). Overall, however, seaweed industries in the northeast USA remains largely focused on wild harvests, with some recent efforts in aquaculture (Kim et al 2014 2017; Johnson et al 2014; Redmond et al 2014; Augyte et al 2017). In particular, there is an interest to develop S. latissima culture in the rural, economically impoverished region of eastern Maine (Hall-Arber et al 2005), to both diversify local industries and preserve the traditional fishing lifestyle.…”

There is an interest to develop sugar kelp (Saccharina latissima) cultivation in the rural, eastern Maine region of the USA. Future farming efforts would benefit from an understanding of the genetic diversity and population structure of kelp, to inform management and conservation, and to identify genetic resources. The purpose of the present study was to characterize the fine-scale population genetic structure of kelp in eastern Maine, using twelve microsatellite loci. A total of 188 samples were genotyped from five sampling locations. Overall, kelp exhibited relatively low genetic diversity and small but significant differentiation among populations (FST = 0.0157). The greatest genetic difference was detected between two geographically close populations in Penobscot and Frenchman Bays, which is likely due to patterns in the Eastern Maine Coastal Current that may limit meiospore recruitment. The population structure could not be fully explained by an isolation-by-distance model. Fine-scale structuring was also detected among populations along the more continuous, eastern Maine coastline. These differences highlight that sugar kelp populations are finely structured across small spatial scales, and that future management and farming efforts should aim to maintain genetic diversity and assess the culture potential of local populations.

There is a scarcity of research-based data on the factors associated with skin irritation due to algal blooms in seaweed farming. Changes in temperature with an increase in nutrients levels lead to the growth of harmful algal blooms, which produce many active metabolites, some of which induce toxic responses in human including skin irritation. The objective of this study was to identify health problems experienced by seaweed farmers and the seasons when they occur, and how these are treated. A crosssectional study design was used to gather data using structured questionnaire, focus group discussions and key informant interviews. The study was conducted between June and August 2015, in six villages, two from Mainland, and four from Zanzibar Islands, Tanzania. Study revealed that seaweed more than 50% of farmers experienced skin irritation problem, followed by 30.4% who had eye related problems, and only 19.6% had respiratory disorders as the most serious. Hot season, which is associated with algal blooms, was the period with the highest occurrence of skin irritation. No specific medication was used to treat the health problems reported. In some severely affected areas, farmers could not tend to their farms for months, a situation which affected their income. It is suggested that the findings from this study would reduce this knowledge gap and motivate stakeholders especially the policy makers to implement measures, which reduce the health problems observed due to algal blooms in the seaweed farmers.
