OSMOTIC RESPONSES OF SEGARA ANAKAN FINE SHRIMP (Metapenaeus elegans) ADULTS IN VARIOUS SALINITY AND MOLTING STAGES
Get PDFA research on eco-physiological characteristics of fine shrimp (Metapenaeus elegans) with special emphasis on the osmotic responses and isosmotic medium requirement for adult spawners in various molting stages was conducted. Adult stocks of M. elegans origin from the Segara Anakan lagunas of the South West of Central Java region were collected and used as experimental shrimps. The shrimps were hold in three 500 l-acclimation tanks and treated according to Anggoro and Nakamura’s method. The seawater salinity level in the tank 1, 2, and 3 was 25, 28, and 22 ppt, respectively. Osmotic response of the shrimps was examined during 3 molting stages, i.e. pre-molt/ post-molt, molt, and inter-molt phases by using an automatic microosmometer Roebling. The results showed that osmotic responses were closely related to the salinity of water medium and molting stages. It was also found that the minimum osmotic works of fine shrimp occurred in isosmotic medium, i.e. 16 to 20 ppt for post-molt, 28 to 30 ppt for molt, and 22 to 25 ppt for inter-molt stages. It was concluded that the range of isosmotic media for the adult of fine shrimp was 22 to 28 ppt or equals to 642.06 to 817.31 mOsm/l H2O

The characteristics of male forewing are black fuscous along the entire costa, white fuscous with brown-tinged from the discal cell towards dorsum and two black spots on the discal cell. The hindwing is predominantly white fuscous tinged with brown from the cubito-anal (CuA 1 and CuA 2) area towards dorsum, with an orange-tinged basal line of terminal cilia which becomes paler towards tornus. In the male genitalia, the distinguishing character of this species is a strongly sclerotised apex of the finger-shaped uncus. In the female, the forewings are white-ochreous tinged with brown, more pronouncedly so toward the margins, with a black reniform spot at discal cell, indistinct black dots at margin and a yellow-orange basal line of terminal cilia. Description. Male (Fig 1) : Wing length 14 mm. Head grey. Labial palpus grey, slender, about 2 times vertical diameter of eye, pointed last segment directed slightly forward.

Coll. J.F. Watung, Genitalia slide MZB. Lepi. 173. Etymology. This species is named after its collector, J.F. Watung (junior author) who has collected extensively larvae in clove plantation in North Sulawesi and reared them during two and half months to get the adults. Distribution and biology. This species is distributed across North Sulawesi following the presence of clove trees in that area. The species is recorded in the following five districts: Minahassa, South Minahassa, North Minahassa, Bolaang Mongondow and South Bolaang Mongondow. The larvae of this species feed in the bark and bore the stem of clove tree (Syzygium aromaticum: Myrtaceae) forming a shallow tunnel (2-3 cm in deep) for burrowing and pupation. The active larvae always build a shelter from the frass or a mix of frass and leaves to protect the burrow from water and predators. Remarks. This species is sexually dimorphic, the male is about half the size of the female. As in other species of Cryptophasa, the male antennal ciliae are also longer than those in the female. Most conspicuous is the different wing pattern between the sexes: the male has predominantly black forewings, whereas the female has predominantly white forewings.Published as part of Sutrisno, Hari & Suwito, Awit, 2015, Discovery of Cryptophasa Lewin, 1805 (Lepidoptera: Xyloryctidae) from Indonesia with the descriptions of three new species, pp. 122-132 in Zootaxa 3994 (1) on pages 123-127, DOI: 10.11646/zootaxa.3994.1.6, http://zenodo.org/record/23206

No full textThe creativity of Antonius Wahyudi Sutrisno (Dedek) in creating the composition be an interesting thing for the author to be further investigated. This research was focused on the factors behind Dedek in finding creative ideas. Dedek works based on tradition reiterates that he uses the idiom of tradition in his works. The idioms used a series of structures, motifs or patterns, and techniques. From the idiom invention, the author observed the tradition one, of such pathet space, instruments (gamelan), and a model of the work, which all is associated with the science of Javanese gamelan. Through pathet space, the author assume that Dedek has a unique in terms of the selection range of tones, although, that is uncommonly performed in tradition karawitan. The exploration of the instruments and methods in use in Dedek works, gamelan instruments perceived authors have character and distinctive characteristics. While on the model of Dedek composition is not far from the tradition of serving space and schema structure that resembles a traditional convention. This research reviewed the more clearly about the characters of the existing tradition in Dedek works that came from the tradition idioms.

ANALYSIS OF WATER SALINITY LEVEL OF FREQUENCY MOLTING IN VANNAMEI SHRIMP (LITOPENAEUS VANNAMEI) ABLATED
No full textMedia salinity is a masking factor that plays an important role in controlling the process of shrimp molting and osmoregulation. Both of them are ecophysiological factors for shrimp life, so it is necessary to know the optimum level or range of media salinity for each phase of the molting phase changes in the stage and osmoregulation phase. This study was conducted to examine the molting frequency of adult L. vannamei which was ablated and cultivated at various levels of salinity. This research was carried out for 60 days. This study uses experimental laboratory methods with a systematic randomized design (RAS) with 4 treatments and 3 replications in each treatment. The treatments tested were salinity with S1 treatments (10 ppt, 289.20 mOsm / l postmolt H2O isosmotic), S2 (15 ppt, 432.80 mOsm / l H2O initial intermolt isosmotic), S3 (25 ± 1 ppt, 725, 15 mOsm / l H2O isosmotic final intermolt) and S4 (29 ± 1 ppt, 820.10 mOsm / l H2O isosmotic molt). Data were analyzed with ANOVA. Meanwhile, the difference in effect between treatments was obtained through Duncan's multiple area test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency was in the S4 treatment (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it should pay attention to the needs of isoosmotic media, namely media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency is in the treatment of S4 (29 ± 1 ppt) (close to isoosmotic molt) 10 times.

Ethnotaxonomical Study of Mole Crab (Crustacea:Hippoidea) on Coastal Community of Cilacap
Get PDFLocal wisdom is a cultural heritage that needs to be preserved. The Cilacap’s coastal communities have traditional taxonomy knowledge that hasn’t been informed, especially about mole crab. This study aimed to explore the ethnotaxonomy knowledge of sand crabs (Crustacea: Hippoidea) in Widarapayung coastal communities. The purposive snowball sampling was used for the method, followed by observation and semi-structured interviews with 30 respondents. Data were analyzed descriptively based on observations and interviews. The results showed that the coastal communities in Widarapayung tourist areas could be divided into five groups, namely catchers, collectors, processors, traders, and consumers. The catcher was able to recognize and describe three types of sand crabs based on the shape of the body and their catchment areas. Captured crabs had the local name of ‘yutuk jambe’ (Emerita emeritus Linnaeus 1767), the appellation was based on carapace shape that resembled the shape of areca fruit; ‘Yutuk bathok’ (Hippa adactyla Fabricius 1787), had the carapace shape resembling a coconut shell, and ‘yutuk Kethek’ (Albunea symmysta Linnaeus 1758), had ornaments on the carapace surface similar with a monkey face, there were dense setae on the edge of the carapace, spiny long antennas and aggressively pinch when captured. The knowledge and skills of sand crabs classification and local name entitlement acquired by the people were in accordance with the Berlin’s model.
