AbstrakIkan betutu Oxyeleotris marmorata merupakan ikan lokal potensial menjadi komoditas budidaya. Performa pertumbuhan dan kelangsungan hidup dapat ditingkatkan dengan mengembangkan wadah budidaya. Tujuan penelitian adalah mengetahui jenis wadah budidaya yang optimal dalam mendukung pertumbuhan dan kelangsungan hidup. Perlakuan yang di uji adalah kolam tanah, kolam hapa dan kolam terpal berukuran 3 m x 2 m x 1 m. Ukuran benih yang digunakan 15±1,39 cm dengan bobot 250,04±1,70 g dengan padat tebar 25 ekor/kolam. Selama 120 hari masa pemeliharaan, pakan yang diberikan adalah ikan rucah sebanyak 30% dari bobot tubuh dengan frekwensi 2x sehari. Hasil penelitian menunjukkan perbedaan jenis wadah berpengaruh nyata terhadap pertambahan bobot dan laju pertumbuhan spesifik, namun tidak berpengaruh nyata terhadap kelangsungan hidup. Pertambahan bobot terbaik terdapat pada perlakuan jenis wadah kolam tanah sebesar 53,86±1,10 g dengan laju pertumbuhan spesifik 0,45±0,010 %bobot tubuh/hari dan kelangsungan hidup 85,33±6,11%. Kualitas air pada seluruh wadah pemeliharaan masih mendukung pertumbuhan dan kelangsungan hidup. Hasil penelitian ini dapat dijadikan informasi dasar dalam pemilihan wadah budidaya yang efektif dan efisien dalam pengembangan budidaya ikan betutu secara optimal.Kata kunci: ikan betutu; pertumbuhan; kelangsungan hidup; wadahAbstractSand goby (Oxyeleotris marmorata. Blkr) is a potential fish species for aquaculture in Indonesia. However, the growth and survival rate performance can be improved by developing cultivation containers. The research objective was to determine the optimal type of cultivation container to produce high growth and survival rate. The ponds treatments used in this experiment were soil pond, hapa pond and tarpaulin pond with measuring 3 m x 2 m x 1 m. The initial fish length average was 15±1.39 cm, with the initial body weight average of 250.04±1.70 g with the stocking density of 25 individual/pond. During 120 days of the rearing period, the fish were fed with trash fish with a proportion of 30% of body weight with the frequency of feeding 2x a day. The results showed differences in the type of container significantly affected weight gain and specific growth rates but did not significantly affect survival rate. The best weight gain was found in the treatment of soil pond containers at 53.86 ± 1.10 g with a specific growth rate of 0.45 ± 0.010% body weight/day and survival rate of 85.33 ± 6.11%. Water quality in all containers still supports growth and survival rate. The results of this study can be used as necessary information in the selection of effective and efficient aquaculture containers to produce optimal sand goby culture.Keywords: sand goby; growth; survival rate; container

Hemibagrus nemurus is a local commodity fish that is especially favored by people in South Sumatra, Java and Kalimantan. The low survival rate of H. nemurus in the seed rearing phase is one of the obstacles in developing its cultivation. In this study an environmental modification was carried out in the rearing of H. nemurus seed containers through the addition of aeration and recirculation to increase the growth and survival. The study was conducted at a hatchery of farmers in the Kemang area, West Java. The initial length of seed was 10.1 ± 0.17 mm. The container size used was 300 liters of fiberglass. Stocking density was 10 fish / L. The maintenance period was 1 month. The treatments tested were rearing of seeds in an aquarium using A) Aeration system, B) Recirculation System, and C) Aeration + Recirculation System. The results showed that the use of rearing containers equipped with Aeration + Recirculation system resulted in better growth (29.4 mm) and survival (24.5%) compared to rearing in containers with only aeration or recirculation systems. Key words : Aeration,Growth, Hemibagrus nemurus, Recirculation, Survival rate

Teripang pasir, Holothuria scabra merupakan komoditas hasil laut yang bernilai ekonomis tinggi. Penangkapan berlebihan stok di alam mendorong berkembangnya kegiatan budidaya. Penempelan merupakan fase kritis pada larva teripang karena terjadi peralihan sifat planktonis ke bentik yang memerlukan substrat. Penelitian ini bertujuan untuk mengetahui preferensi penempelan, pertumbuhan, dan sintasan larva H. scabra fase penempelan pada substrat lamun yang berbeda. Penelitian menggunakan metode rancangan acak lengkap dengan perlakuan empat jenis daun lamun berbeda dan lima ulangan. Perlakuan terdiri atas Enhalus acoroides (L-1), Syringodium isoetifolium (L-2), Cymodocea serrulata (L-3), dan Cymodocea rotundata (L-4). Jumlah awal larva sebanyak 1.000 individu dan substrat dirangkai dengan luasan yang sama sebesar 12 cm x 17 cm untuk setiap unit penelitian. Hasil penelitian menunjukkan jenis lamun yang digunakan sebagai substrat berpengaruh secara nyata terhadap preferensi penempelan dan sintasan larva teripang pasir, namun tidak berpengaruh terhadap pertumbuhan. E. acoroides menunjukkan hasil terbaik dengan preferensi penempelan 0,26 ind. cm-2 dan sintasan 10,66%; sehingga layak digunakan sebagai substrat penempelan dalam pembenihan teripang pasir, H. scabra.Holothuria scabra larvae on different seagrass substrates. By: Lisa Fajar Indriana, Yuli Afrianti, Sitti Hilyana, and Muhammad FirdausSandfish Holothuria scabra is marine commodities with a high economic value. Overfishing of natural stocks has compelled an interest to begin aquaculture practice. Settlement is a critical phase for the planktonic larvae as they will transform to benthic form in the presence of substrate. This study aims to evaluate the settlement preferences, growth, and survival rate of H. scabra larvae settled on different seagrass leaves. The research was conducted using the Completely randomized design with four different species of seagrass leaves and five replications. The treatments consist of Enhalus acoroides (L-1), Syringodium isoetifolium (L-2), Cymodocea serrulata (L-3), and Cymodocea rotundata (L-4). Initial number of larvae was 1,000 individuals and the substrate was set with same widthof 12 cm x 17 cm for each unit. Results of the experiment indicated that settlement preference and survival rate of H. scabra larvae was significantly affected by seagrass used as substrate while no significantly differences was observed for growth of larvae. E. acoroides showed the best result with 0.26 ind. cm-2 settelement preference and 10.66% survival rate, so that suitable to be used as settlement substrate in H. scabra hatchery.

The aim of this study was to determine the growth and survival rate of Ctenopoma fish seeds. This study used a completely randomized design with 3 treatments and 3 replications. The treatment in this study was a different feeding rate using natural feed of Tubifex sp  namely A (8%), B (10%), and C (12%) ). The test fish used was Ctenopoma fish seeds with an initial length of 2.40 ± 0.10 cm and an initial weight of 0.32 ± 0.05 g. Fish seeds are cultivated  for 28 days with feeding frequency twice a day. The results of research showed that the use of different feeding rate had an significantly different (P<0.05) on the specific growth  rate and absolute length growth with the best results in the treatment C. The survival rate was not significantly different between treatments (P>0.05). Key Words: Ctenopoma, feeding rate, growth, survival rate

This study aimed to evaluate the growth, survival rate, and resistance to acute hepatopancreatic necrosis disease (AHPND) of white leg shrimp (Penaeus vannamei) by using Lactobacillus plantarum, Lactobacillus fermentum, and Pediococcus pentosaceus mixed with feed, and at the same time supplying CNP in a ratio of 15:1:0.1 to the water. As a result, the treatments that shrimp were fed with feed containing lactic acid bacteria (LAB), especially L. plantarum, have increased shrimp growth, total hemocyte cells, granulocyte cells, and hyaline cells significantly (p < 0.05) in comparison to the control group. The supply of CNP to the water has promoted the intensity of V. parahaemolyticus effects on shrimp health and significantly decreased total hemocyte cells, granulocyte cells, and hyaline cells by 30–50% in the period after three days of the challenge, except in L. plantarum treatment, which had only a 20% decrease compared to other treatments. In CNP supplying treatments, the AHPND infected rate and mortality of shrimp were higher than those in other treatments. In summary, the supply of CNP had significantly reduced the shrimp’s immune response and promoted the susceptibility of shrimp to AHPND in both cases of use with and without LAB-containing diets.
