“…Major breakthroughs are necessary in the area of harvesting, storage and distribution of the biomass in order to maintain their contents intact and avoid decomposition. But the sustained increase in cultivated areas must be accompanied by a proper legislation that drives the development of the industry while protecting the natural kelp beds to avoid other environmental issues associated with uncontrolled exploitation (Buschmann et al 2013). The development of a seaweed industry must take into consideration the coastal communities with the intensification of the exploitation of the resource (review Frangoudes 2011 for the evolution of seaweed management regimes in four countries).…”

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 extraction. Recently, new possible markets are developing for this species, for example human consumption and biofuel/chemical production that could increase the demand and justify the development of a commercial cultivation system. The objective of this work was to present the recent development of the seafarming of M. pyrifera in Chile, focusing on the fundamental determinants of productivity in cultivated systems and the identification of the binding constraints to productivity. Three experimental plots (up to 21 Ha) were designed and deployed in three study areas (Caldera in northern Chile and Quenac and Ancud in southern Chile) to test different environmental conditions. During a period of 3 years, sporophytes produced in an indoor hatchery were deployed monthly, at different densities, and followed until harvest. Environmental parameters and biomass were monitored on a monthly basis. Our findings demonstrate the feasibility of Macrocystis seafarming on a large scale in Chile. Important differences in yield were observed between the study areas associated with either environmental physical or biological factors, such as the presence of herbivores. Our best production cycle reached 124 WMT Ha−1 month −1 in southern Chile, and the worst, less than 20 WMT Ha−1 month−1 in northern Chile. Finally, some direct and indirect constrains were encountered, including seeding season and depth, and the presence of pests and diseases, that are discussed.

“…Unlike other countries, disease and pest surveillance in Chile has been regulated by a national law and the information through various reporting criteria, including a list of dangerous pests, and pathogens (see the previous section) has been gathered. 94 Technical, equipment and detection procedures have also been installed in a few national research centres to support and enhanced surveillance capacity in Chile, but official surveillance system is yet to start. 12 Through an effective surveillance monitoring system, it is possible to reveal the status of disease and pests.…”

Gracilaria aquaculture is one of the fastest-growing sectors, contributing to 10.5% of the global seaweed feed-stock supply chain in 2019. It predominantly caters to foodgrade agar, animal feed and non-food sector applications viz. biotechnology, biomedical and pharmaceuticals. It has witnessed a rapid expansion triggered by increased demand due to commodity trade. Biosecurity-related issues are the key factors constraining its expansion, but are seldom addressed. The global gracilarioids aquaculture is dominated by China and other Asian countries, namely the Republic of Korea, Indonesia, the Philippines and Vietnam. This paper provides an assessment of their national biosecurity capacity, including current risk management strategies, policies and the implementation of existing regulations. It also highlights specific gaps in national policies and regulations, which can be addressed to improve their health management systems. Biosecurity management strategies, such as the provision of clear regulatory guidance, mechanisms for notifying disease and pest outbreaks, movement of live seaweed, risk assessment, stakeholder incentivisation and certification are recommended. Further, insights into the impending biosecurity measures to the emerging countries in this domain namely India and Malaysia are discussed. We suggest, implementing a uniform format of global integrated biosecurity measures Vaibhav A. Mantri and Cicilia S. B. Kambey have contributed equally to this study.

“…Particularmente, el uso de los cultivos de macroalgas es de gran interés para el desarrollo de una acuicultura sostenible al absorber parte de los residuos inorgánicos que produce el cultivo de peces y moluscos. Esta asociación de organismos con diferentes niveles tróficos o nutricionales constituye un sistema de policultivo integrado, conocido como acuicultura multitrófica integrada (Buschmann et al 2013). Por otra parte, las laminarias son actualmente utilizadas comercialmente en alimentación humana y como fertilizante y forraje para la acuicultura de herbívoros como el erizo de mar y la oreja de mar García Tasende and Rodríguez González 2003;Peteiro and García-Tasende 2015).…”

ResumenLas macroalgas marinas contienen polisacáridos, lípidos y proteínas, entre otros componentes orgánicos, que se pueden utilizar para producir diferentes biocarburantes. Sin embargo, la producción de bioetanol es el que ha despertado actualmente un mayor interés por el alto contenido de polisacáridos (40-75% de su peso seco) que presentan algunas grandes algas conocidas con el nombre de laminarias. Estas macroalgas marinas pueden utilizarse para la producción de bioetanol mediante un proceso de hidrólisis y fermentación de sus polisacáridos que ha sido mejorado recientemente para su aplicación industrial. Las laminarias ya se utilizan comercialmente para consumo humano, extracción de compuestos con múltiples aplicaciones industriales, pienso y forraje de animales y fertilizante. En este contexto, la acuicultura marina de laminarias en la costa atlántica de España puede constituir una fuente renovable, sostenible, limpia de biomasa para la obtención de bioetanol, además de otros productos con valor comercial. Su cultivo tendría importantes beneficios económicos pero también ambientales, al reciclar carbonos atmosféricos y nutrientes inorgánicos del medio marino. En la presente revisión se presenta una visión del proceso de producción de bietanol a partir de biomasa de laminarias y se discute el potencial de la maricultura de laminarias como fuente para producir bioetanol y otros bio-productos de valor en base a experiencias en la costa atlántica de España. Palabras clave: acuicultura marina, aplicaciones, biocombustibles, macroalgas, kelp. AbstractSeaweeds contain polysaccharides, lipids and proteins, among other organic components, which can be used to produce different biofuels. However, bioethanol production has attracted more interest recently due to high content of polysaccharides (40-75% of dry weight) in kelps. These seaweeds can be used for bioethanol production by the hydrolysis and fermentation of polysaccharides which it has been recently improved for industrial use. Kelps are already intended for direct human consumption, industrial extraction of valuable compounds, animal husbandry and agricultural 16
