“…No epiphytes have been discovered on the tissue-cultured K. alvarezii, while the presence of epiphytes and symptoms of "ice-ice" disease were observed on the conventional cultivated seaweeds [101]. From the analyses of their semi-refined carrageenan properties, tissue-cultured K. alvarezii was found to produce higher carrageenan yield with significantly better quality in viscosity, gel strength, and sulfate content ( Table 3) in contrast to conventional cultivated seaweeds [131]. Table 3.…”

“…Comparison of the quality between tissue-cultured and conventional cultivated K. alvarezii (Figure 7) has been reported especially on their growth rate and carrageenan properties [131]. After 60 days of post-cultivation from their first introduction as seedlings in open sea, tissuecultured K. alvarezii has been reported to achieve higher growth rate (6.3 ± 0.1% day −1 ) as compared to conventional cultivated seaweeds (3.4 ± 0.3% day −1 ).…”

Seaweeds are a primary source of hydrocolloids, which can be processed into various food additives, cosmetics, and pharmaceuticals. The inability of current commercial seaweed farming projects to meet industrial demands is underscored by a plethora of challenges, which include the lack of high-quality germplasm with the desired cultural characteristics. This chapter describes the current trends in commercial seaweed production and the potential technological advances in production methods and genetic selection strategies, which can be applied to raise the productivity of seaweed farms. Molecular markers have become increasingly relevant to the selection of a diverse range of wild varieties for domestication, and this augurs well for strain identification. The development of high-density linkage maps based on molecular markers offers an avenue for the implementation of molecular breeding strategies based on quantitative trait loci (QTLs). Concurrently, productivity of existing varieties can be enhanced by the analysis of exogenous factors known to affect the growth and survival of tissue-cultured seedlings. The application of photobioreactors for tissue culture is another important development, which will be digressed upon. In addition to this, quality control which focuses on the comparison of chemical and physical qualities of the tissue-cultured and conventional cultivated seaweeds will become increasingly relevant to the development of industry standards for sustainable seaweed production to fulfill the increasing demands of seaweed-related industries.

“…Rumput laut dengan bibit konvensional dalam laporan Abdullah (2011) memiliki laju pertumbuhan 4,546% tiap hari dengan pemanenan 30 hari. Namun, Lym Yong et al, (2014) menyatakan bahwa laju pertumbuhan K. alvarezii hasil kultur jaringan mencapai 6,3% tiap hari.…”

“…Hal ini dikarenakan pada saat setelah minggu ketiga, warna rumput laut yang telah memucat dan kekuningan berubah menjadi segar dan spesifik kembali karena cuaca sudah mulai baik. Namun laju pertumbuhan harian rumput laut Kapapphycus alvarezii masih rendah jika dibandingkan dengan hasil kultur jaringan Lym Yong, et al, (2014) yang mencapai 6,3% per hari.…”

Seaweed is one of the important commodities of fishery products that have economic value. Farmers often use repetitive seeds from the same broodstock so that they have the potential to experience a decline in quality. So it is necessary to do a study of seaweed cultivation using tissue culture seedling with the long line method as an effort to develop seaweed farming. Seaweed (Kappaphycuz alvarezii) has an absolute growth of 138.61 grams, with a growth rate of 4.85%. The growth of seaweed from tissue culture seedlings is better than the growth of conventional seedlings. ABSTRAKRumput laut merupakan salah satu komoditas penting hasil perikanan yang memiliki nilai ekonomis. Petani sering menggunakan bibit yang berulang-ulang dari sumber indukan yang sama sehingga berpotensi mengalami penurunan kualitas. Sehingga perlu dilakukan studi mengenai budidaya rumput laut menggunakan bibit hasil kultur jaringan dengan metode long line sebagai upaya pengembangan usaha budidaya rumput laut. Rumput laut (Kappaphycuz alvarezii) memiliki pertumbuhan mutlak 138,61 gram, dengan laju pertumbuhan 4,85%. Pertumbuhan rumput laut dari bibit hasil kultur jaringan lebih baik dibandingkan dengan pertumbuhan dari bibit konvensional.Kata Kunci : Rumput laut; Kappaphycuz alvarezii; Pertumbuhan; Metode Long line.

“…Peningkatan kualitas agar yang terjadi pada rumput laut hasil kultur jaringan dikarenakan adanya input nutrien selama kultur di laboratorium. Input nutrien pada media kultur dapat meningkatkan polisakarida atau sintesis pikokoloid pada rumput laut (Yong et al, 2014;Lüning, 1990).…”

Penelitian ini bertujuan untuk mengevaluasi performa bibit rumput laut Gracilaria verrucosa. hasil kultur jaringan yang dibudidayakan di salah satu daerah sentra produksi rumput laut di Sulawesi Selatan. Penelitian dilaksanakan di Desa Murante Kecamatan Suli Kabupten Luwu, Sulawesi Selatan pada 2014 selama tiga siklus pemeliharaan dengan lama pemeliharaan 40 hari/siklus. Luasan tambak yang digunakan pada siklus pertama adalah 1,2 ha; siklus kedua 2 ha; dan siklus ketiga 4 ha. Sebagai perlakuan adalah bibit rumput laut hasil kultur jaringan dibandingkan dengan rumput laut lokal sebagai kontrol. Padat penebaran bibit rumput laut adalah 1.000 kg/ha yang dipelihara dengan metode tebar dasar. Penimbangan rumput laut dilakukan pada awal dan akhir penelitian untuk mengetahui laju pertumbuhan harian (LPH) dan produksi, sedangkan kandungan agar dianalisis setelah panen. Analisis data dilakukan secara deskriptif dan disajikan dalam bentuk grafik dan tabel. Dari tiga siklus budidaya menunjukkan bahwa bibit rumput laut hasil kultur jaringan memiliki performa pertumbuhan, produksi, dan kandungan agar yang lebih tinggi dibandingkan bibit rumput laut lokal dengan perbedaan masing-masing 12,1%; 17,8%; dan 6,7%. Pertumbuhan tertinggi terjadi pada siklus kedua, sedangkan kandungan agar tertinggi terjadi pada siklus ketiga baik pada bibit hasil kultur jaringan maupun bibit lokal. Bibit rumput laut Gracilaria sp. hasil kultur jaringan dapat dijadikan alternatif sumber bibit yang berkualitas.This study was aimed to evaluate the performance of G. verrucosa seaweed seed produced from tissue culture and cultivated at the seaweed production center in Murante Village Suli District Luwu Regency South Sulawesi in 2014. The seeds were cultivated for three production cycles, with each cycle lasted for 40 days. The first culture period was conducted in 1.2 ha, the second in 2 ha, and the third in 4 ha of pond areas. The treatments consisted of two different seaweed seed sources, i.e: tissue cultured seaweed seed and local seaweed as a control. The seaweed stocking density used was 1.000 kg/ha cultivated using broadcast method. The daily growth rate (DGR) and biomass as production indicators were measured at the initial and the end of the culture period. The agar yield was measured after harvest. The data were analyzed descriptively and presented in graphical visualization and data tabulation. The present study showed that tissue cultured seaweed had a higher performance in terms of growth, biomass production, and agar yield with the values of 12.1%, 17.8%, and 6.7%, respectively, than that of the local seedling. The highest DGR was produced at the second cycle, and the highest agar yield was measured at the third cycle for both of seaweed seedlings. Given this result, tissue cultured seaweed can be an alternative source of quality seeds.
