Prior to getting high production, seaweed farm owners or workers should understand cultivation methods. They involve cultivation technique, place, species of seaweed, methods for selecting seed, growth, resistance against plant disease, spacing, appropriate time to start planting, control and supervision, harvesting and also marketing. The objective of the study was to describe growth, production and carrageenan of K.alvarezii grown using selected seed that is phenotype (F4) seed. The study lasted for 45 days. The experimental study consisted of 2 treatments, pre- and post-sexual seed. The parameters were growth and production. The cultivation method used was long line method. The data analysis was student t-test. The absolute growth of seaweed using selected (F4) seed was 334, 8 ± 0, 12 g-874, 8 ± 0, 14 g while that using seeds from cultivator was 105, 0 ± 0, 06 g-454, 8 ± 0, 06 g. The Specific Growth rate selected seed (F4) seed was 3.25 ± 0, 13–6.34 ± 0, 14 % day^-1, and seeds from cultivator was 2.05 ± 0, 03-2.49 ± 0, 05 % day^-1. Seaweed production using selected seed (F4) seed was 30,245 kg/m². Carrageenan yield of the selected seed (F4) seed was 57.32% day^-1 and that of the seeds from cultivator was 19.17% day^-1. Selected seed (F4) seed had significant influence towards growth and production of K.alvarezii. Selected seed (F4) seed resulted in the highest rate of growth and production in K.alvarezii. Quality of water was within adequate range to grow K.alvarezii.
