“…Loureiro et al (2010;2012) reported that brown seaweed A. nodosum (liquid form) as enrichment increased the daily growth rate (5.5 -5.6%) of cultured K. alvarezii, which is similar to our result with SGR of 5.23% in enriched K. striatus. Also, AMPEP significantly increased the growth rate (7.3%) in K. alvarezii (Loureiro et al, 2014), relatively higher than our study. The ice-ice disease of Kappaphycus is usually associated with changes in environmental factors like light intensity, salinity, and temperature manifested with extensive whitening of the branches, which are further degraded by the presence of opportunistic bacteria (Largo et al, 1995a and1995b;Tahiluddin andTerzi, 2021a andTahiluddin et al, 2021c).…”

Kappaphycus striatus is one of the most important eucheumatoid species that is widely farmed worldwide. In the southern Philippines, where the initial farm was established, sluggish growth of farmed Kappaphycus species brought about by the poor quality of planting materials and extensive farming resulting in unproductive farms and frequent ice-ice outbreaks have been a hindrance in increasing the seaweed production. As a result, farmers have led to the application of inorganic fertilizers as nutrient enrichment for Kappaphycus. However, inorganic or chemical fertilizers always pose negative impacts on the environment. Hence, in this study, a preliminary investigation on the potential use of extracts of brown seaweeds Sargassum cristaefolium and Turbinaria conoides as bio-fertilizers was tested on K. striatus for their growth rate, carrageenan yield, and ice-ice disease occurrence. Seaweed liquid extracts (SLE): S. cristaefolium (SC), T. conoides (TC), combination of SC and TC (MX), and control (C) were utilized as bio-fertilizers for K. striatus. SLE-enriched K. striatus seedlings were cultivated in a seaweed farm using the fixed-off bottom method for 45 days. Results revealed that the specific growth rates of all SLE treatments were significantly higher than no SLE treatment at day 45. The percentage of ice-ice disease and the yield of carrageenan did not differ among treatments. Enrichment of K. striatus using SLE of two selected brown seaweeds before out-planting could improve growth rates while not affecting the ice-ice disease occurrence and carrageenan yield. Hence, formulated SLE from brown seaweeds S. cristaefolium and T. conoides can be used as potential bio-fertilizers for Kappaphycus cultivation.

“…A commercial extract from Ascophyllum nodosum, known as Acadian Marine Plant Extract (AMPEP) was shown to increase daily growth rate and carrageenan yield in K. alvarezii, as well as reduce negative effects of epiphytes (Hurtado et al, 2009;Luoreiro et al, 2010;Borlongan et al, 2011). The AMPEP was also reported to have a "vaccine-like" property (Luoreiro et al, 2012), as well as increased carrageenan yield although it did not alter the gel strength (Luoreiro et al, 2014). Yoon et al (2015) used three fertilisers, namely AMPEP, Gofar600 (GF) and natural seaweed extract (NSE) in concentrations of 3 mg L -1 .…”

A Grand Challenge programme was initiated at the University of Malaya under the Equitable Society Research Cluster, to introduce seaweed farming to the coastal communities at Bachok district, Kelantan. Cultivation trials of selected commercial seaweeds like Kappaphycus (source of carrageenan), Gracilaria (source of agar), Gelidium (source of agar and pulp) and Ulva (salad) will be conducted using onshore and offshore systems, and the data collected is used for the techno-economics analysis. This paper discusses the techno-economics of various cultivation systems, as well as the importance of community empowerment, as a guide to the formulation of a roadmap for the integration of seaweed farming into the Bachok coastal communities. Abstrak Satu Program Grand Challenge telah dimulakan dibawah Kluster Penyelidikan Equitable Society di Universiti Malaya bagi memperkenalkan pengkulturan rumpair laut kepada komuniti persisiran pantai di daerah Bachok, Kelantan. Percubaan pengkulturan rumpair laut terpilih seperti Kappaphycus (sumber carrageenan), Gracilaria (sumber agar), Gelidium (sumber agar dan pulpa) dan Ulva (salad) akan dilaksanakan dengan menggunakan sistem tepi pantai (on-shore) dan luar pantai (off-shore), dan data-data yang dikumpulkan ini digunakan dalam analisis tekno-ekonomi. Makalah ini membincangkan teknoekonomi bagi pelbagai sistem pengkulturan serta kepentingan pemberdayaan komuniti, sebagai panduan kepada perumusan pelan hala tuju untuk mengintegrasikan pengkulturan rumpair laut ke komuniti pesisiran pantai Bachok.
