“…Also, increased interest in prospecting and evaluating new Gelidium -based agarophyte resources is emergent in other countries, such as G. spinosum in Tunisia (Ben Said et al 2009, 2013), G. crinale and Pterocladiella capillacea in Egypt (Ibrahim et al 2015), G. crinale in Argentina (Croce et al 2015), G. corneum in Algeria (Nil et al 2016), and G. elegans in Malaysia (Ajdari and Zarshenas 2016). …”

Bacteriological and technical agars are in short supply with potential consequences for research, public health, and clinical labs around the world. To diagnose bottlenecks and sustainability problems that may be putting the industry at risk, we analyzed the available time series for the global landings of Gelidium, the most important raw materials for the industry. Data on the harvest of Gelidium spp. have been reported since1912, when Japan was the only producer. After World War II the diversification of harvested species and producing countries resulted in a strong increase in global landings. Maximum harvest yields of almost 60,000 t year−1 in the 1960s were sustained until the 1980s, after which landings decreased continuously to the present. In the 2010s, a reduction in the global production to about 25,000 t year−1 was observed, which was lower than the yields of the 1950s. Landings by important producers such as Japan, Korea, Spain, and Portugal have collapsed. This is the ultimate cause of the present shortage of bacteriological and technical agars. However, an important factor at play is the concentration of the global landings of Gelidium in Morocco, as its relative contribution increased from 23% in the 1960s to the present 82%. Two specific bottlenecks were identified: restrictive export quotas of unprocessed Gelidium in favor of the national agar industry and resource management regulations that were apparently not enforced resulting in over-harvesting and resource decline. The global industry may well be dependent on resource management basics. Simple harvest statistics must be gathered such as the harvest effort and the variation of harvest yields along the harvest season. We discuss how this information is fundamental to manage the resource. The available harvest statistics are generally poor and limited and vary significantly among different sources of data. Probable confusions between dry and wet weight reporting and poor discrimination of the species harvested need to be resolved.

“…Climate change and ocean acidification modify macroalgal populations globally [1,2]. Some algae used in industry (e.g., agar-producing Gelidium) are already declining and more knowledge of their growth and developmental mechanisms is required to ensure a sustainable replenishment of their currently exploited wild biomass [3].…”

The COST Action Phycomorph (FA1406) was initiated in 2015 from a handful of academic researchers, and now joins together 19 European countries and nine international partners. Phycomorph's goal is to coordinate and develop research on developmental biology in macroalgae. This is an ambitious project, as the related scientific community is small, the concepts are complex, and there is currently limited knowledge of these organisms and there are few technologies to study them. Here we report the first step in achieving this enterprise, the creation of the Phycomorph network. We share the associated strengths, pitfalls, and prospects for setting up the network in the hope that this might guide similar efforts in other fields.

Red algae are a phylum of about 7100 mostly marine, unicellular and multicellular photosynthetic eukaryotes that belong to the Supergroup Plantae. Multicellular taxa consist exclusively of a filamentous construction lacking true tissues despite their often superficially complex plant body. This group is unique in the Tree of Life in lacking both flagella and centrioles with a 9 + 2 microtubule arrangement in all stages of the life history. They include species with elaborate life cycles, significant ecological importance and extensive economical applications. The oldest known taxonomically resolved eukaryotic fossil, ca. 1250–1100 million years ago, is a red alga. Key Concepts Red algae are crucial organisms for understanding the evolution of sex and life cycles. Red algae are crucial organisms to understand the evolution of multicellularity since the oldest eukaryote on record is a red alga. Red algae are important in the evolution of photosynthetic eukaryotes since their ancestor hosted a cyanobacterium that became the plastid through the event of primary endosymbiosis. Mitochondrial genomes among multicellular red algae are highly conserved, supporting the notion of a rapid radiation among the morphologically divergent multicellular lineages. The calcifying coralline red algae are widespread, long‐lived barometers of ocean health and real‐time indicators of global warming and ocean acidification impacts.
