“…These GRs are much higher than those obtained for other commercial carrageenophytes from the Chilean coast such as G. skottsbergii (ca. 0.3% day −1 ) (Buschmann et al 2001) and Sarcothalia crispata (1.2–1.4% day −1 ) (Ávila, Ask, Rudolph, Nuñez & Norambuena 1999), which indicates the suitability of C. chamissoi for mariculture in the region.…”

The e¡ects of temperature, photon £ux density and photoperiod on the growth rate of female gametophytic and tetrasporophytic thalli of Chondracanthus chamissoi from four populations along the Chilean coast were studied in vitro. Both reproductive phases survived and grew under all the conditions tested, with growth rates varying between 0.1 and 7.5% day À 1 . The results showed higher growth rates with increases in temperature and photon £ux density levels. The growth rate was higher in female gametophytic thalli in almost all treatments. The photoperiod did not cause signi¢cant di¡erences in the growth rate for either reproductive phases in any of the populations studied. Temperature was the principal factor a¡ecting the growth rate of C. chamissoi.

“…Production of seaweeds in Chile has been based mainly on the harvest of wild populations, with commercial cultivation being restricted to a single species, Gracilaria chilensis Bird, McLachlan & Oliveira. The success of Gracilaria cultivation stimulated the establishment of new seaweed‐processing plants in Chile in the last 10 years, which resulted in an increase in the demand for raw material (Ávila, Ask, Rudolph, Nuñez & Norambuena 1999; Buschmann, Correa, Westermeier, Hernández‐González & Norambuena 2001a). This is also partly due to the development of carrageenan industries and an increase in the demand of seaweeds for human consumption (Buschmann et al 2001a).…”

First attempt to cultivate the carrageenan-producing seaweed Chondracanthus chamissoi (C. Agardh) Kutzing (Rhodophyta; Gigartinales) in Northern Chile

Chondracanthus chamissoi is an important source of carrageenan in Chile. Presently, all the production is harvested from wild populations. This study reports the ¢rst attempt to cultivate C. chamissoi. Experiments were conducted with female gametophytic and sporophytic thalli by inserting them among braids of a 7 mm polypropylene rope. Inoculated ropes were placed at 1, 3 and 5 m depths in two sheltered bays in northern Chile. The fronds adapted well to cultivation and grew at all the depths tested, although the greatest increase in biomass was observed at 1m depth. On a yearly cycle, higher biomass increases were observed in autumn and winter months compared with the spring and summer. We believe that by adapting the cultivation methodology, this species could be cultivated year round.

“…The advantages of high survival and fast growth of vegetative propagules can be extended to the commercial cultivation of C. crassicaulis . In the cultivation of red algae, seedlings derived from spores showed very low attachment and survival, slow growth, and heavy contamination by epiphytes (Ávila, Ask, Rudolph, Nuñez, & Norambuena, ; Ávila, Candia, Romo, Pavez, & Torrijos, ; Romo, Alveal, & Werlinger, ; Romo et al, ). In contrast, the use of larger vegetative propagules yielded large amounts of high‐quality seedlings, at a reduced cost of care.…”

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.
