Wadah percobaan berupa bak fiber volume 1 m3, abalone dipelihara dalam keranjang plastik ukuran 45 cm x 45 cm x 25 cm sebanyak dua buah/bak, sedangkan teripang dipelihara di dasar bak dengan sistem air mengalir. Kepadatan abalon 50 ind./keranjang dan teripang 100 ind./bak. Ukuran panjang dan bobot juvenil teripang yang digunakan adalah 3,17 ± 0,77 cm; 1,74 ± 0,64 g; dan benih abalone 3,16 ± 0,48 cm dan 4,82 ± 0,87 g. Jenis pakan abalon berupa rumput laut Gracilaria sp. dan Ulva sp. sedangkan teripang diberi pakan berupa bentos selama enam bulan pemeliharaan. Sebagai perlakuan adalah pemeliharaan teripang dan abalon: A (tanpa pemberian bentos), B (ditambah bentos), dan C (ditambah bentos dan tanpa abalon), masing-masing perlakuan diulang tiga kali. Parameter yang diamati meliputi pertumbuhan, sintasan, kualitas air, dan kandungan proksimat feses abalon. Hasil menunjukkan bahwa pertumbuhan juvenil teripang pasir berbeda nyata (P<0,05); rata-rata panjang total dan bobot badan pada perlakuan B lebih tinggi (4,45 ± 1,06 cm; 8,06 ± 1,19 g) dibandingkan dengan perlakuan lainnya. Sebaliknya sintasan juvenil teripang pasir tidak berbeda nyata antar perlakuan (P>0,05). Pertumbuhan bobot benih abalon berbeda nyata antar perlakuan (P<0,05) dengan nilai rata-rata pada perlakuan A (16,75 ± 2,96 g) dan B (12,77 ± 2,69 g). Sedangkan pertumbuhan panjang cangkang dan sintasan tidak berbeda nyata (P>0,05). Produktivitas polikutur pada perlakuan A mencapai 208,54 g untuk teripang dan 4.656 g untuk abalon; diikuti perlakuan B mencapai 118,55 g untuk teripang dan 3.493 g untuk abalon dan perlakuan C sebesar 34,50 g.The aim of the research was to examine the grow-out efficiency of sea cucumber, Holothuria scabra, and abalone, Haliotis squamata fry in a polyculture system. The research was conducted in the Institute for Mariculture Research and Fisheries Extension, Gondol. Containers used in this research were nine fiberglass tanks each with a volume of 1 m3. The abalone fry were reared in two baskets sized 45 cm x 45 cm x 25 cm while sea cucumber fry were reared on the bottom of the tank and. Water exchange used a flow-through system. The density of abalone was 50 fry/basket and sea cucumber was 100 fries/tank. The averages of length and body weight of sea cucumber were 3.17 ± 0.77 cm and 1.74 ± 0.64 g, respectively. The abalone fry had the averages of length and body weight of 3.16 ± 0.48 cm and 4.82 ± 0.87 g, respectively. Feeds used for the abalone fry were Gracilaria sp. and Ulva sp. while for sea cucumber was benthos. These feeds were used during the six months of the research. Treatments were grow-out of sea cucumber and abalone: A (without benthos), B (with benthos), and C (with benthos but without abalone), each treatment had three replicates. Parameters measured were growth and survival rate, water quality, and proximate analysis of abalone feces. The results showed that the growth of sea cucumber was significantly different (P<0.05), mean of total length and body weight of treatment B was higher (4.45 ± 1.06 cm; 8.06 ± 1.19 g) compared to the two other treatments. On the other hand, the survival rate of sea cucumber fry was not significantly different among treatments (P>0.05). The growth of body weight of abalone was significantly different (P<0.05) among the treatments in which the average for treatment A was 16.75 ± 2.96 g and treatment B was 12.77 ± 2.69 g. The growth of carapace length and survival rate were not significantly different (P>0.05). The productivity of polyculture in treatment A reached 208.54 g for sea cucumber and 4,656 g for abalone; followed by treatment B of 118.55 g for sea cucumber and 3,493 g for abalone and treatment of C 34.50 g.

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 thermal structure of the environmental atmosphere associated with Terrestrial Gamma-ray Flashes (TGFs) is investigated with the combined observations from several detectors (FERMI, RHESSI, and Insight-HXMT) and GNSS-RO (SAC-C, COSMIC, GRACE, TerraSAR-X, and MetOp-A). The geographic distributions of TGF-related tropopause altitude and climatology are similar. The regional TGF-related tropopause altitude in Africa and the Caribbean Sea is 0.1–0.4 km lower than the climatology, whereas that in Asia is 0.1–0.2 km higher. Most of the TGF-related tropopause altitudes are slightly higher than the climatology, while some of them have a slightly negative bias. The subtropical TGF-producing thunderstorms are warmer in the troposphere and have a colder and higher tropopause over land than the ocean. There is no significant land–ocean difference in the thermal structure for the tropical TGF-producing thunderstorms. The TGF-producing thunderstorms have a cold anomaly in the middle and upper troposphere and have stronger anomalies than the deep convection found in previous studies.

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.
