This work presents the first results of a trial using a mechanical harvester prototype to harvest K. alvarezii cultivated in Brazil. This prototype is a
modifcation of the mechanical harvester used in mussels farms cultivated in a continuous system. Using the same system, seedlings of K. alvarezii
were cultivated in the summer using tubular nets in the summer time, in rafts floated with specifcally designed buoys. When the seedlings achieved
the harvesting size, preliminary field trials were carried out to assess the operational performance of the mechanical harvester. Data of a) Operational
Production Capacity (OPC), which corresponds to the amount of seaweed the prototype can harvest per unit of time; b) Seaweed Damage Index (SDI),
and c) Return Index (RI), the later corresponding to the amount of seaweed remaining in the tubular nets during the mechanized harvest, were
assessed. The tubular nets had a mean length of 2.6 m and a mean weight of 30.6 kg with the seaweed at the moment of the harvest. The average OPC
assessed was 1.8 kg s-1 (SD = 0.27) which corresponds to 6,624.2 kg h-1 (SD = 987.4); the SDI was 0% and the average RI was 11.6% (SD = 1.47). Based
on these preliminary results, we believe that an OPC around of 11,000 kg h-1 could be achieved when considering an average of 11.8 kg m-1 biomass
contained in the tubular nets, in an individual or in a continuous tubular net. |
