Published: October 2017

<p>One of the success factor in the cultivation of pearl oysters (<span style="text-decoration: underline;">Pinctada</span> <span style="text-decoration: underline;">maxima</span>) within laboratory scale of is the ability of the larvae to settle on the collector. Stocking collectors which are not on time with an irregular position could cause a decline in seed production. The research was conducted from 25 July to 27August 2011 at Laboratory of Marine Bio-industry Technical Implementatation Unit, Research Centre for Oceanography, Indonesian Institute of Sciences, Lombok, West Nusa Tenggara (NTB). The aim of the study was to observe the attachment of larvae at different position and depth. Analysis of variance showed that larvae settlement was influenced by depth instead of position and the interaction between them. Real Honest Different Test showed that in the 20 cm depth was significantly different from 60 cm and 100 cm in number of larvae attached on the collector. The highest survival rate was in 20 cm depth with 68,98% (516 larvae) while in 60 cm was 17,11% (128 larvae) and 100 cm (9,22% (69 larvae), and the others were attached on the wall of the tank 4,68% (35 larvae).</p> <p>Keywords: settlement ability of pearl oyster’s larvae (<span style="text-decoration: underline;">Pinctada</span> <span style="text-decoration: underline;">maxima</span>), collector, depth</p>

<p>Zooplankton community was studied in Lamalera Sea and Sawu Sea during DIKTI-P2O LIPI Expedition from 19 – 30 July 2011. Besides being a potential fishing ground, the Lamalera sea and Sawu Sea have been a migration path for Cetacean (large marine mammals), particularly during the southeast monsoon season. The purposes of this study were to investigate community structure, abundance, and spatial distribution of zooplankton in the Lamalera Sea and the Sawu Sea. Plankton samples were collected from 23 stations, by NORPAC 300 µm-net that was vertically hauled from maximum 200 meter depth up to the surface water. The result showed that there were 45 taxa of zooplankton, which was dominated by copepods . The abundance of the zooplankton between 491 - 4537 individu/m<sup>3</sup>. Average diversity index and evenness values were 1.59 ± 0.21 and 0.50 ± 0.04, respectively. In this area, Creel has been found in all research stations but the abundance was small. Species composition was relatively the same between sampling stations suggesting that there was no different in composition between north and south parts, which virtually comprise of different water masses. It showed that spatial distribution of zooplankton was relatively wide-reaching.</p> <p>Keywords: zooplankton, copepoda, creel, Lamalera sea, and Sawu Sea.</p>

Published: October 2017

<p>Several types of grouper hybrid seeds can now be massively produced in a hatchery. Hybrid seeds can increase diversification of aquaculture species and potential to increase fish production. Therefore, an improvement in hybrid seed production both in high quantity and quality is very important. This research was conducted to produce massively cantik grouper hybrid seeds i.e.,a crossbreed between female tiger grouper (Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon). This research examined the cantik grouper seed production compared with the production of tiger grouper and marbled grouper fingerlings. The research results showed that cantik hybrid grouper seeds production had higher survival rate (24.59%) than tiger grouper (17.44%) and marbled grouper (4.63%). The total length of the seed at the age of 45 days for cantik grouper was 3.59 ± 0.21 cm, tiger 3.24 ± 0.55 cm, and batik 2.61 ± 0.42 cm, respectively. Seed abnormality for cantik grouper was 4.13%, tiger grouper 30.21%, and marled tiger 0.57%, respectively. Based on genetic variation analyses, the cantik grouper had a closer genetic relationship with the marbled grouper compared with the tiger grouper.</p> <p>Keywords: Marbled grouper, hybridization program, seeds production, quality</p>

<p><em>The structure and spatial extent of a coastal front and circulation in the shallow (&lt;55 m depth) northeastern Java Sea in Indonesia was investigated with a new dataset of high-resolution conductivity-temperature-depth (CTD) and along-track shipboard acoustic Doppler current profiler (SADCP) during a DIKTI-LIPI 2010 joint research cruise on R.V. Baruna Jaya 8. The coastal front separates fresh warm coastal water derived mainly from Barito River discharge and the saline, cool Java Sea water. The surface fresh water plume extends approximately 760 km from the Barito River estuary to the south, and its thickness varies from the surface to 10 m and 20 m depth, depending on its proximity to the fresh water source. The front is aligned a northeast and east direction, probably related to a meandering of strong northeastward monsoon current in the eastern part of the Java Sea during the observation time.</em></p> <p><em> </em></p> <p><strong><em>Keywords:</em></strong><em> hydrographic measurement, coastal front, Matasiri Islands, Barito River, the northwest</em><em> monsoon current</em></p>

<p><em>The study of seaweed biodiversity was conducted in Ory, Pelaw, Kailolo, and Waimital coatal waters of Haruku island in 2011. The purposes or this study were to determine the density and biodiversity of makroalgae in the coastal waters of the Haruku island. Data collection were conducted in June-September 2011 with square transect line method. The results showed that in the coastal area of Kailolo exhibited the highest value in density and biodiversity of macroalgae in the study regions with 47 species from 31 genera consisting of 21 species of red algae, 14 species of green algae and 13 species of brown algae. Gracilaria, Acanthophora, Sargassum, Turbinaria, Caulerpa, and Halimeda were the most dominance in the region. The highest biomass of macroalga found in the Kailolo coastal waters was due to its relatively good habitat contidion consisting of dead coral rubble, sand, coral live with seagrass vegetation dominated by Thalasia hemprizii and Halodule uninervis. Meanwhile, habitat condition at the other locations had suffered a severe damage and dominated by dead coral. Environmental conditions in the study region were within the limits of decent support for the growth of macro algae.</em></p> <p><em> </em></p> <strong><em>Keywords:</em></strong><em> Macroalgae, diversity, biodiversity, substrat, Haruku island</em>

Published: October 2017

<p><em>Quality deterioration of fish </em><em>is </em><em>caused by various factors, one of </em><em>them </em><em>is due to the activity of cathepsin enzyme. Cathepsin enzyme activity can be inhibited by enzyme</em><em> </em><em>inhibitors</em><em>. Inhibitors of the enzyme can be obtained from fish meat tissue by separating the enzyme-inhibitor complex with heat treatment. The purpose of this research was to extract and apply the cathepsin inhibitors to inhibit deterioration of fish quality. This research was conducted in three </em><em> </em><em>steps: (1) the determination of the optimum extraction temperature for extraction of cathepsin inhibitors, (2) the determination of the most potent cathepsin inhibitors with various concentrations, and (3) the application of cathepsin inhibitors in inhibiting the deterioration of fish quality. The results showed that the cathepsin inhibitors was optimally extracted at 80°C. Cathepsin inhibitors diluted using buffer with a ratio of 1: 1 had the same relative activity with</em><em>out</em><em> dilution. The process of quality deterioration of milkfish control in chilling temperatures occured after 504 hours (21 days) storage with a 24-hour observation time interval. The complete process during observation was pre-rigor (0 hour ), rigor mortis (96 hours), post-rigor (360 hours), and deterioration (504 hours). The process of milkfish quality deterioration treated with soaking in cathepsin inhibitors occured after 624 hours (26 days) storage with the detailed process as follows: 0 hour (pre-rigor), 144 hours (rigor mortis), 408 hours (post-rigor), and 624 hours (deterioration). </em><em>Thus</em><em> fish marinated with cathepsin inhibitors achieve slower deterioration phase 5 days.</em><em></em></p><p><strong><em> </em></strong><strong><em>Keywords: </em></strong><em>cathepsin inhibitor, deterioration, pre-rigor, rigor mortis, post-rigor, quality deterioration.</em></p>
