Demostration of the feasibility of Macrocystis seafarming in a large scale in Chile
Article
The red alga Gracilaria chilensis C. J. Bird, McLachlan & E. C. Oliveira (Agarophyton chilense Gurgel, J.N.Norris & Fredericq) is one of the few algae commercially farmed in Chile, where this alga is commonly named “Pelillo”. G. chilensis main by-product is agar, a gelling agent used in the food and pharmaceutical industries. This alga is also a va...

We report for the first time the occurrence of the Japanese kelp Saccharina japonica on the Pacific coast of southern Chile following an illegal introduction for aquaculture purposes. In November 2020, a citizen complaint indicated that the non-native kelp was being illegally farmed in Canal Caicaén. Specimens of the non-native kelp were collected...
Article
Macroalgal holobiont studies involve understanding interaction among the host, its microbiota and the environment. We analyzed the effect of bacteria–kelp interactions on phenotypic responses of two genetically‐distinct populations of Macrocystis pyrifera (north and south) exposed to different nitrogen (N) concentrations. In co‐culture experiments...

Inbreeding, the mating between genetically related individuals, often results in reduced survival and fecundity of offspring, relative to outcrossing. Yet, high inbreeding rates are commonly observed in seaweeds, suggesting compensatory reproductive traits may affect the costs and benefits of the mating system. We experimentally manipulated inbreed...

The capacity of marine organisms to adapt and/or acclimate to climate change might differ among distinct populations, depending on their local environmental history and phenotypic plasticity. Kelp forests create some of the most productive habitats in the world, but globally, many populations have been negatively impacted by multiple anthropogenic...
Article
Macrocystis pyrifera gametophytes growing under controlled conditions produce juveniles with different numbers of fronds, i.e. few (≤ 2) or multiple fronds (≥ 3). We describe these morphotypes and test whether the number of fronds may impact juvenile growth by performing laboratory and field experiments. Kelp reproductive material was collected in...

The objective of this study was to test, using a field experiment, the effect of geno- typic diversity on productivity of farmed populations (Ancud and Chaica, Chile) of the domesticated red alga Agarophyton chilense (formerly known as Gracilaria chilen- sis), a species considered as economically important in Chile. Monoclonal and poly- clonal (4 a...

Monoclonal and polyclonals (4 and 8...
Article
The holobiont concept recognizes that macroalgae functioning, in an ecological setting, cannot be understood without considering interactions with their associated microbiome. In this study, the structure of bacterial communities on the giant kelp Macrocystis pyrifera from two different genetic populations was analyzed in localities with contrastin...
Article
Understanding how climate change may influence ecosystems depends substantially on its effects on foundation species, such as the ecologically important giant kelp (Macrocystis pyrifera). Despite its broad distribution along strong temperature and pH gradients and strong barriers to dispersal, the potential for local adaptation to climate change va...
Article
The interest in seaweeds by humans seems to have originated over 1700 years ago when several seaweed species became used in ethnic cuisines. These initial applications enabled the start of farming in Japan, China and Korea. However, in Western countries, demand for seaweed polysaccharides began only after World War II, when the demand for agar, alg...
Article
Full-text available
During the domestication process, farmers influence the reproduction and care of organisms to ensure a predictable supply of the resource of interest, causing changes in phenotypic and genotypic character frequencies. In Chile, as a result of unconscious selection and domestication process, farmed populations of the red alga Agarophyton chilensis h...
Article
Bio‐oil can be effectively used for the preparation of bio‐based materials due to their chemical compositions. Herein macroalgal derived bio‐oil was used for the synthesis of carbon dots by simple hydrothermal process. A simple and facile hydrothermal process was explored for the preparation of green emitting graphene oxide‐carbon dots (GO‐CDs) com...
Article
Chile, located in the southeastern Pacific, possess a high richness of seaweed species, some of which have been traditionally extracted from natural beds for the production of hydrocolloids (e.g. agar, carrageenan and alginates), but still a high proportion of the biomass is being exported as dried material to processors in Asia and Europe. During...
Article
The demand for seaweed biomass for hydrocolloid industries and novel products for the food, pharmaceutical, cosmetics and agro-industry has been steadily increasing during the last decade. This trend is expected to continue into the future as new uses are discover and the ever-increasing human population needs for healthy products and clean energy...
Article
Full-text available
In terrestrial plants, it is well known that genetic diversity can affect responses to abiotic and biotic stress and have important consequences on farming. However, very little is known about the interactive effects of genetic and environmental factors on seaweed crops. We conducted a field experiment on Gracilaria chilensis to determine the effec...
Article
Full-text available
Abstract Chile is one of the main producers of seaweeds in the world; however, most of the production comes from harvesting natural beds and only 2.4% from cultures, dominated by the agarophyte Gracilaria chilensis. One of the most exploited resources is the giant kelp Macrocystis pyrifera, which is sold fresh for abalone feed and dry for alginate...
Article
The accelerated development of seaweed aquaculture is stimulating research on the genetic drivers of phenotypic diversity of the target species, in order to optimize breeding strategies, to help determine the choice of source populations, and for the selection of traits and varieties that fit with the environmental variability of the production sit...
Article
Full-text available
Macroalgae are photosynthetic, multicellular, sessile eukaryotic organisms that offer diverse habitats for the colonization of epiphytic bacteria, therefore establishing biological interactions of diverse complexity. This review focusses on the interactions between macroalgae and their Epiphytic Bacterial Community (EBC); the main aims are to ascer...

The use of seaweeds has a long history, as does the cultivation of a select and relatively small group of species. This review presents several aspects of seaweed production, such as an update on the volumes of seaweeds produced globally by both extraction from natural beds and cultivation. We discuss uses, production trends and economic analysis....

Full-text available
In this paper, we address several issues related to seaweed domestication from an evolutionary and ecological perspective. We briefly cover the history of human interactions with seaweed and assess the importance of pre-domestication evolutionary processes. The various steps of the trajectory from wild to domesticated seaweeds are discussed for fiv...
Article
Interest in third-generation biomass such as macroalgae has increased due to their high biomass yield, absence of lignin in their tissues, lower competition for land and fresh water, no fertilization requirements, and effi cient CO2 capture in coastal ecosystems. However, several challenges still exist in the development of cost-effective technolog...

Conference Paper
Full-text available
we created a germplasm bank for 3 different populations of the giant kelp in the coast of Chile and assessed its viability after 5 years in suspended state. There are ever-growing pressures to harvest the giant kelp for abalone aquaculture and kelp stocks need to be managed in order to main the genetic biodiversity. It is known that in Chile there...
Article
Kelp cultivation started in Japan, China and Korea, mainly for human consumption; new applications are still expanding. In Chile, three "wild" Lessonia species and Macrocystis pyrifera are under a strong and increasing pressure of exploitation mainly for alginate production and as a source of feed for abalone. Regulatory restrictions for kelp explo...
Article
The identity of two phaeophycean taxa that monopolized the middle-lower rocky intertidal zone of a coastal area chronically exposed to copper mine wastes in northern Chile was unraveled. One of them was preliminarily identified as the gametophytic stage of Scytosiphon lomentaria (Lyngbye) Link. The other, a dark crust, resembled the alternate stage...

Project
This project aims to generate the knowledge and infrastructure needed to restore and buffer New Zealand’s productive Macrocystis pyrifera kelp-forest ecosystems against the threats of a changing ocean. A comprehensive genetic and physiological analysis of New Zealand’s M. pyrifera population will guide the selection of climate change resilient strains to be used for regional restoration efforts. This project endeavours to safeguard and enhance valuable coastal fisheries through a bottom up restoration approach that compliments on-going efforts of top-down fisheries restocking of culturally and commercially important species (www.mahingakai.org.nz). Approaches developed throughout this project will also help drive the development of a nascent algal aquaculture industry within New Zealand. The project is funded by a three-year, Ministry of Business Innovation and Employment, Smart Ideas Grant. It involves collaboration between national and international scientists as well as customary and commercial fisheries managers.
