Seaweed Variety Growth Different (Halyemenia durviela and Caulerpa racemosa) with the Off- Bottom Method

Seaweed varieties, Halymenia durviela and Caulerpa racemosa, hold a significant economic value since they can be used as raw materials in food, medicine, and cosmetics. Therefore, proper cultivation methods are essential to enhance the productivity of these seaweeds. This study aimed to assess the growth effects on C. racemosa and H. durviela and identify which variety exhibits the best growth performance. Two different seed variety treatments were tested, each with three replications. The treatments were as follows: Treatment A involved C. racemosa seeds, and Treatment B involved H. durviela seeds. The data analyzed included absolute weight growth and relative growth rates. The results indicated that the off-bottom method influenced the growth of both seaweed varieties, with Halymenia durviela showing the best results in terms of absolute weight growth and relative growth rates.
