The analysis of reproductive viability for the cultivation of Chondracanthus chamissoi has been performed of three populations of the Peruvian coast: Paiján (7 ° 46 'S, 79 ° 25.4' W), Ancón (11 ° 46 S, 77 ° 11.3 'W) and Mendieta (14 ° 3.5 'S; 76 ° 15.72' W) under two cultivation methods: via carpospores and by vegetative propagation based on the formation of secondary attachment discs (SAD). Specimens were collected from the wild population and separated according to their life stage in cystocarpic and vegetative (no obvious reproductive structures). “Broths“ of carpospores from cystocarpic specimens were prepared and then inoculated in culture experimental systems (bottle of 4L with artificial substrates of polypropylene ropes) obtaining values of average settlement of 750 ± 100 carpospores/cm2 in Ancón, 450 ± 50 carpospores/cm2 in Paiján and 600 ± 100 carpospores/cm2 in Mendieta. After 120 days of culture, the number of surviving seedlings was 31 ± 17 thalli/cm2 in Ancón, 18 ± 4 thalli/cm2 in Paiján and 49 thalli/cm2 in Mendieta. On the other hand, the vegetative specimens were fixed on scallop shells with rubber bands and placed in culture systems. After 20 days, fronds were removed and SAD formation was evident in all populations. After 120 days the number of SAD at the end of the experiment was 5.8 ± 1.9 SAD/shell to Ancón, 4.8 ± 2.2 SAD/shell to 9.1 ± 7.8 Paiján and SAD/shell to Mendieta. Experimental results have demonstrated the feasibility of the three populations to develop vegetative and via carpospores culture. The population of Mendieta in the light of the results was the most appropriate to implement vegetative and via carpospores culture. Cultivation based on carpospores proved the most beneficial given their high reproductive potential, though both strategies can be widely used
