The cultivation of red algae represents the most recent expansion in the global production of macroalgae. The most cultivated species are Kappaphycus alvarezii, K. striatus and Eucheuma denticulatum, which are the main sources of raw material for carrageenan production. Due to the different socio-economic benefits generated by seaweed mariculture, several countries have adopted this activity as an alternative livelihood in coastal communities. In order to contribute on the development of macroalgae mariculture in Venezuela, a preliminary field study on the growth of Eucheuma isiforme, an endemic iota-carrageen species from the Caribbean Sea, was carried out. Two suspended culture systems were evaluated: horizontal (long line) and vertical (floating raft). The cultivation technique consisted of tying vegetative implants using plastic raffias (tie-tie) to main polypropylene lines of 6 mm in diameter. The initial average weight of the implants varied between 20-25 g, with a planting density of 0.06 kg.m-2 in the horizontal system and 0.02 kg.m-2 in the vertical system. The bioassay lasted nine weeks between February-April 2017, recording a variation on biomass growth over time. The daily growth rate (wet biomass) was 5.54 ± 0.31 % in the horizontal system and 6.69 ± 0.12% in the vertical one. The growth of E. isiforme recorded during this study in Charagato Bay is considered high when compared to other cultivation experiences carried out in the Caribbean basin, being considered an adequate site for the development of commercial seaweed mariculture in Venezuela.
