Preferensi Teripang Pasir Holothuria scabra Terhadap Pakan Berbahan Dasar Makroalga

Abstract

<p class="Papertext"><strong>The Preference of The Sandfish Holothuria scabra on Macroalgae-Based Feed. </strong>The sandfish, <em>Holothuria scabra</em>, is one ofthe marine species that has the potential to be developed as a source of high-value functional food. However, the growth of sandfish is still constrained by the availability of suitable feed. This study aimed to determine the level of preference of sea cucumbers for artificial feed made from macroalgae. This study used six main ingredients: control (sea-sand), FF-1 (commercial shrimp feed), FF-2 (<em>Padina</em> sp.), FF-3 (<em>Ulva</em> sp.), FF-4 (<em>Sargassum</em> sp.), FF-5 (combination). A completely randomized design with three replications was implemented. Nutritional values of feed and the sandfish body, feed consumption, specific growth rate (SGR), survival, and water quality were investigated. The results revealed that all treatments had a 100 percent survival rate, even though the SGR for all treatmentswere negative. Artificial feed made from <em>Padina</em> sp. (FF-2) had the highest average feed consumption of 0.51 gram/day. This value was significantly greater than the other treatments (p<0.05). The SGR reached a positive value in the last week of the maintenance phase. The nutritional quality of the sandfish body generally decreased compared to the initial rearing condition. On the other hand, water quality was optimal for sandfish growth throughout the experiment.It can be concluded that the feed derived from <em>Padina</em> sp. is preferable for <em>Holothuria scabra </em>and has the potential to be further developed.</p>

Application of Sargassum sp extract on juvenile sandfish nursery

“…The availability of more food ingredients makes it easier for sandfish juveniles to get food in sufficient quantities as needed so that juvenile growth in treatment C is better than treatment A and treatment B. This assumption is in accordance with the statement [7] that food availability is an important factor in increasing the optimal growth of sandfish.…”
