“…Seaweeds can provide complete or partial protein nutrition for abalone (Bautista-Teruel, Millamena, & Fermin, 2001;Bilbao et al, 2012;Kemp, Britz, & Aguero, 2015;Mulvaney, Winberg, & Adams, 2013;Viera et al, 2011), sea urchins (Cook & Kelly, 2007) and shrimp (Cruz-Suarez, Tapia-Salazar, Nieto-Lopez, Guajardo-Barbosa, & Ricque-Marie, 2009;da Silva & Barbosa, 2009;Felix & Brindo, 2013). In contrast, the inclusion of seaweed in diets of commercial fish (herbivores or carnivores) at levels greater than 10% results in reduced growth and feed utilisation (Table 2), although there are some promising results for tilapia (Stadtlander et al, 2013).…”

“…Pemberian pakan alga makro segar yang lebih dari satu atau dua alga makro yang berbeda menghasilkan pertambahan panjang dan lebar cangkang yang terbaik (Rusdi dkk., 2010). Pemberian pakan kombinasi alga makro akan mampu mengimbangi kebutuhan nutrien yang tidak terdapat pada alga makro lain sehingga dapat mencukupi kebutuhan nutrien juvenil abalon H. squamata dan dapat mendukung pertumbuhan yang lebih baik (Kemp et al, 2015).…”

“…Priyambodo dkk. (2005) menyatakan bahwa spesies abalon sangat menyukai pakan alga makro segar dan jenis pakan yang dipilih oleh abalon cenderung jenis yang mengandung unsur hara dan komposisi kimia yang dibutuhkannya serta memiliki nilai nutrisi seimbang (Fleming et al, 1996;Kemp et al, 2015). Namun jika dilihat pada pertumbuhan juvenil abalon yang diperoleh pada pakan tunggal Gracilaria sp.…”

Teknologi produksi benih dan pakan abalon Haliotis squamata telah berhasil dikembangankan oleh Balai Besar Penelitian dan Pengembangan Budidaya Laut, Gondol, sedangkan pakan untuk pendederan juvenil abalon masih memerlukan pengembangan lebih lanjut untuk memperoleh bahan pakan yang optimum untuk pertumbuhan. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan beberapa jenis alga makro segar (Ulva sp., Gracilaria sp., Halymenia sp.) yang diberikan dalam komposisi tunggal ataupun kombinasi (7 komposisi) terhadap pertumbuhan juvenil abalon H. squamata. Rancangan penelitian yang digunakan yaitu menggunakan Rancangan Acak Lengkap (RAL) 3 kali ulangan. Percobaan dilakukan dalam keranjang plastik ukuran 287 x 140 x 52 mm dengan kepadatan 25 ekor (berat badan 1,75 ± 0,08 g, panjang cangkang 21,96 ± 0,34 mm, lebar cangkang 13,37 ± 0,24 mm). Pengukuran abalon dilakukan setiap 2 minggu sekali, dan pemeliharaan abalon dilakukan selama 87 hari dengan pemberian pakan setiap 2 hari sekali. Hasil penelitian ini diketahui bahwa perlakuan dengan pemberian pakan kombinasi Ulva sp., Gracilaria sp., dan Halymenia sp. memberikan pertumbuhan yang paling baik pada berat badan (BB), panjang cangkang (PC), serta lebar cangkang (LC), berturut-turut yaitu 4.70±0.20 g, 30.61±0.44 mm, serta 18.94±0.26 mm, sedangkan perlakuan pakan Halymenia sp. yang terendah. Nilai rasio konversi pakan (FCR) terendah yaitu pada perlakuan Ulva sp. dan Halymenia sp. 13,55±1,06, dan tertinggi yaitu pada perlakuan Gracilaria sp. 23,89±2,63.

“…Among the different SW genera, Ulva spp. have become widely used due to their nutritional profile (Ortiz et al, 2006) and its introduction as a dietary supplementation has been investigated in several research lines (e.g., Abdel-Warith et al, 2016;Bautista-Teruel et al, 2001;Bilbao et al, 2012;Cook and Kelly, 2007;Ergün et al, 2009;Kemp et al, 2015;Valente et al, 2006). In addition, dietary SW supplementation may positively affect the stress response and disease resistance of the aquatic animal, which is an advantage in intensive aquaculture systems (Amaro et al, 2019;Fleurence et al, 2012).…”

The fatty acid (FA) profile of oysters generally reflects the dietary FA composition. Moreover, incorporation of FA into tissues is modulated by various metabolic factors, and final composition will depend upon the dietary sources, cumulative intake, and oysters' development stage. Thus, the aim of this study was to assess the impact of dietary incorporation of seaweed (SW) Ulva rigida, in replacement of traditional microalgae diet, on the FA composition of Pacific oysters Crassostrea gigas, during broodstock conditioning. The dietary conditioning consisted of direct replacement of microalgae (33% Tisochrysis lutea, 50.25% Skeletonema costatum, and 16.75% Chaetoceros calcitrans) by SW at four different substitution levels (0%, 25%, 50%, and 100% diet). The dietary docosahexaenoic acid (DHA) (22:6n‐3) and eicosapentaenoic acid (EPA) (20:5n‐3) contents showed a positive correlation with the dietary microalgae level. During the trial, oysters fed with higher percentages of microalgae revealed a depletion of DHA and accumulation of EPA. The 100% SW caused a significant reduction in oxygen consumption and, consequently, in the standard metabolic rate. Based on these results, a partial substitution of up to 25% of dietary microalgae seems to be a suitable alternative, because it elicited similar results to the commercial 100% microalgae diet.
