ABSTRACT. When facing the growing, international demand for the species Chondracanthus chamissoi as a source of carrageenan and for human food consumption, it is very important to generate new aquaculture techniques that allow for its repopulation, maximizing biomass yield whilst reducing the pressures on existing small, natural populations. This paper describes the use of secondary attachment discs (SAD) as a new vegetative propagation technique. It involves the following two stages: i) Tying the tetrasporophytic and cystocarpic fronds to natural substrates (shells and rocks), the conditions generated in the tanks allowed for quick SAD formation (12 days of experimentation), and ii) The maintenance of SAD under normal conditions (at sea for 83 days). The results indicated a quick formation of SAD, a high capacity of persistence (40%), the growth of new apices), quick substrate colonization through colonization discs (SADc), and the formation of reproductive structures. As a result, SAD is therefore proposed as both an innovative way to achieve the recovery of the now reduced natural beds of C. chamissoi and as an alternative to traditional methods of vegetative culturing for a species of high commercial interest.

“…Among a few marine red algae (e.g. Gracilaria , Gigartina , Chondracanthus , and Gelidium ), vegetative propagation based on fragments derived from parental thallus has been used for mariculture because it is a faster and cheaper method than the traditional spore‐based technique (Bulboa et al, ; Correa, Beltran, Buschmann, & Westermeier, ; Otaíza, Rodríguez, Cáceres, & Sanhueza, ; Westermeier, Gómez, & Rivera, ). The successful growth of vegetative fragments is initiated via re‐attachment to the substratum (Hernández‐González, Buchmann, Cifuentes, Correa, & Westermeier, ; Pacheco‐Ruiz, Zertuche‐González, & Espinoza‐Avalos, ; Santelices & Varela, ).…”

The red alga Chondria crassicaulis has a wide‐ranging bioactive chemical composition and is used as a local foodstuff, representing a potentially new cultivar in Korea. The cultivation techniques were developed by examining the monthly changes in frond weight in a field population of C. crassicaulis from November 2016 to October 2017. For seedling production, temperature and irradiance effects on the attachment and growth of vegetative propagules of C. crassicaulis were evaluated. In addition, effects of day length and salinity on the propagule growth were examined. C. crassicaulis is a year‐round species with a maximum frond wet weight of 817 mg observed in July 2017, as seawater temperature increases to 20°C. The attachment of vegetative propagules was significantly affected by temperature and irradiance, with maximal values detected at 20–25°C and 60 µmol photons m−2 s−1. The relative growth rates of vegetative propagules of C. crassicaulis were the highest at 20–25°C, 60 µmol photons m−2 s−1, and a salinity of 25 psu. In conclusion, due to its tremendous tolerance under variable environmental conditions, the vegetative propagules of C. crassicaulis can be used as seedlings for mass cultivation.

“…Chondracanthus chamissoi (C. Agardh) Kützing comúnmente conocida como "yuyo", "mococho" o "chicorea de mar", es un alga roja endémica de la costa del Pacífico Sudamericano (5 -42 ° S) (Dawson et al, 1964;Ramírez & Santelices, 1991), que ha sido comúnmente objeto de extracción debido a su importancia comercial como fuente de carragenano y para consumo humano directo (Acleto, 1971;Bulboa et al, 2013). Es debido a esa importancia que diversas investigaciones relacionadas al conocimiento del cultivo de C. chamissoi han sido llevadas a cabo, principalmente en el país de Chile, tales como el desarrollo de cultivos vegetativos por medio de talos fragmentados (Bulboa et al, 2005;Bulboa 2006;Bulboa & Macchiavello, 2006;Bulboa et al, 2013) y sobresalientemente en el cultivo vía esporas (Bulboa & Macchiavello, 2001;Bulboa et al, 2010).…”

“…C. chamissoi tiene estrategias reproductivas que permiten su mantenimiento en praderas naturales tales como la producción de gametos, la producción de carposporas y tetrasporas, la fragmentación del talo (Bulboa et al, 2013) y la formación de un sistema basal crustoso permanente sobre el sustrato que tiene la capacidad de regenerar frondas (Alveal, 2001).…”

Diversos trabajos han sugerido el uso de fertilizantes agrícolas como alternativa de bajo costo al uso de sales inorgánicas de grado analítico para el cultivo masivo (Edding, 1995;Pacheco -Ruíz et al, 2004;Bulboa, 2006;Bulboa et al, 2013). Finalmente, otras variables que afectan el crecimiento y desarrollo de las algas en un cultivo es la turbulencia ocasionada por el movimiento del agua, el pH y la salinidad.…”
