The Status of Domestication and Aquaculture System on Gracilaria verrucosa in Indonesia
摘要
Gracilaria verrucosa, commonly known as seaweed, is a species of red algae (Rhodophyta) found in shallow tropical and subtropical marine environments. This seaweed holds significant economic value and is particularly abundant in Indonesia, especially in regions such as northern Java, West Nusa Tenggara, South Sulawesi, and Lampung (Nurman et al., 2021; Rejeki et al., 2018; Suhartini et al., 2023). Gracilaria verrucosa is recognized as an export commodity (Fatmawati et al., 2022) and is valued for its high fiber content, making it suitable for food products (Darmanto et al., 2022). Additionally, this species of seaweed offers significant economic benefits in various sectors, including gelatine production, human food, pet food, medicine, biofuels, and fertilizers (Nasmia et al., 2021; Torres et al., 2014). Its high growth rate, ease of acquisition, and low cost contribute to the strong demand for Gracilaria in gelatine production (Ak et al., 2011). Gracilaria verrucosa can be cultivated in shallow ponds or harvested from the wild (Rustam & Wamnebo, 2021). However, cultivation methods pose challenges, as the stocking techniques employed by seaweed cultivators often lead to poor production outcomes. Factors contributing to this issue include pests, such as triptan, which prey on the seaweed, and contamination from mud at the bottom of the ponds, negatively impacting quality. Addressing these challenges will be crucial for the future of Gracilaria verrucosa cultivation.
