“…Akumulasi amonia di atas 0,5 ppm sangat berbahaya terhadap larva teripang, namun teripang juga dapat berkembang dengan baik pada konsentrasi amonia 70-430 mg/l atau kurang dari 0,5 ppm. Teripang pasir sendiri memiliki toleransi optimal terhadap amonia <0.5 ppm (Jasmadi, 2018).…”

Sandfish is one of the organisms from Holothuroidea class and Echinoderms phylum. Sandfish can be found throughout coastal waters, from shallow tidal areas to deeper waters. Sandfish prefer waters free from pollutants, and the water movement is relatively calm. To mimic its preference different recirculation aquaculture systems were designed. The recirculation systems consisted of a double bottom filter or a multi-layer filter/filter component that were located inside or outside the system. This research aimed to determine the effects of different recirculation systems on ammonia concentration, behavior and survival of sandfish with the substrates that were replaced every week during the study. The results showed that the different recirculation systems in the three maintenance containers were the best systems in reducing ammonia concentrations and the best survival rates were found in the inner recirculation system and the outer recirculation system. ABSTRAK Teripang pasir merupakan salah satu organisme dari kelas Holothuroidea pada filum Echinodermata. Teripang pasir dapat ditemukan di sepanjang perairan pantai dari daerah pasang surut yang dangkal hingga dalam. Teripang pasir menyukai perairan yang bersih dengan pergerakan air yang tenang. Untuk menyerupakan keadaan, system resirkulasi akuakultur yang bereda dirancangkan. Sistem-sistem resirkulasi tersebut tersusun dari saringan dasar ganda arau beberapa lapis saringan/komponen saringan yang terdapat pada bagian dalam atau bagian luar system. Penelitian ini bertujuan untuk menentukan pengaruh system resirkulasi yang berbeda terhadap konsentrasi ammonia, tingkah laku dan kelulusan hidup teripang pasir dimana substrat pada sistem diganti setiap dua minggu. Hasil penelitian menunjukkan bahwa ketiga system resirkulasi yang berbeda ini sangat baik dalam mereduksi konsentrasi ammonia sedangkan kelulusan hidup terbaik ditemukan pada resirkulasi di dalam dan di luar sistem. Kata Kunci: Sistem resirkulasi, amonia, kelulusan hidup, teripang pasir, Holothuroidea

This study aimed to determine the successive level of fission technique on several sea cucumbers (Holothuroidea) in littoral zone of Madong Bay, Tanjungpinang. The fission technique was performed by tying the middle part of the sea cucumber’s body using a rubber band. Parameters observed were composed of: (a) the occurrence of autotomy on pre- and post-treatment period, (b) successive rate of fission technique (%), (c) fission duration, (d) survival rate on post-treatment period. All data were analyzed descriptively. The results showed that: (1) Only gold sea cucumber Stichopus chloronotus that could perform autotomy on post- treatment period, (2) The successive rate of fission technique on Stichopus chloronotus and Holothuria atra was 83.33% and 33.33%, respectively, while fission was absent on Holothuria scabra and Holothuria sp. (0%), (3) The fastest fission process was found on Stichopus chloronotus at 1.2 hours, after applying the fission technique at 24±2 hours and Holothuria atra was at 24-48 hours, (4) The survival rate on post-treatment period was 66.67% in Stichopus chloronotus and 41.67% in Holothuria atra, while Holothuria scabra was 66.67% and Holothuria sp. was 11.11%. Fission technique is more suitable for Stichopus chloronotus as an alternative method for seed supply in grow-out culture activities.

This research aimed at validating the fully raster-based suitability modelling for sea cucumber (Holothuria scabra) that has been created for the waters of Kiowa Bay, Enggano Island, Bengkulu. To validate the model, eighty-four sea cucumbers were cultivated on two different suitability classes. The field test phase includes setting the cultivation cages; measurement of sea cucumber weight; measurement of water quality parameter; and substrate analysis. Sea cucumbers were put into 2 cultivation cages (Cage 1: highly suitable, and Cage 2: less suitable), and for each cage, it was divided into 3 sub-cages. Before weighing, the sea cucumber was taken out from the water and then put into a tray layered with tissue, and left for 30 seconds. Measurements were conducted at the beginning of the study (t0) and then carried out every three weeks until t3. The data analysis includes the Specific Growth Rate; Daily Growth Rate; Absolute Growth; and Survival Rate. The results showed that the Specific Growth Rate; Daily Growth Rate; Absolute Growth; and Survival Rate at Cage 1 (ie 0.5%; 0.88 gram; 62.28 gram; and 85.71%) better than the same parameters at Cage 2 (ie 0.34%; 0.64 gram; 45.33 grams; and 69.05%). These results indicate that the raster-based data for sea cucumber suitability model has advantages over the sea cucumber suitability model analyzed using vector-based data.
