Abstract:
In this study, valuable polyhydroxynaphthoquinone (PHNQ) pigments were recovered from sea urchin food waste and were investigated as a potential bioactive ingredient for cosmeceuticals. The crude PHNQ pigment extract from 4 Vietnam sea urchins, Diadema setosum, Diadema savignyi, Stomopneustes variolaris, and Tripneustes gratilla, exhibited effective 2,2-diphenyl-1-picryl-hydrazyl-hydrate scavenging activity, tyrosinase inhibitory activity, and antibacterial activity. The moisturizing cream with 0.5% of PHNQ pigments from D. setosum and Tripneustes gratilla sea urchins showed no dermal irritation over 14 days of mouse skin test. Four major active components in PHNQ were identified via high-performance liquid chromatography coupled with diode array detector and mass spectrometry. Echinochrome A contributed considerably to the antioxidant activity of the extracts while those containing echinochrome A and spinochrome E were significantly active against various bacteria. The promising results laid the foundation for establishing a novel process from food waste to innovative biomaterial and formulating eco-friendly skincare products with PHNQ components from sea urchins as precious ingredient.

Abstract:
Echinodermata merupakan biota yang dapat ditemukan hampir di semua ekosistem laut. Echinodermata cukup melimpah keberadaannya di kawasan terumbu karang, hal ini karena terumbu karang berperan sebagai tempat berlindung dan mencari makan bagi Echinodermata. Dalam rantai makanan, Echinodermata memiliki peranan sebagai pemakan seston atau detritus, dan merombak sisa bahan organik. Echinodermata juga berperan sebagai bioindikator parameter kualitas perairan. Penelitian ini bertujuan untuk mengetahui kelimpahan Echinodermata yang terdapat di Pantai Krakal, Gunung Kidul, Yogyakarta dan Pantai Pailus, Jepara, Jawa Tengah. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif. Pengambilan sampel pada penelitian ini menggunakan metode transek kuadran dengan ukuran 1x1m. Hasil pengamatan di Pantai Krakal ditemukan 2 kelas dari filum Echinodermata, antara lain 3 species dari Kelas Ophiuroidea yaitu Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiarachna affinis, dan 3 species dari Kelas Echinoidea yaitu Echinometra viridis, Echinometra oblonga, dan Stomopneustes variolaris. Sedangkan jenis Echinodermata yang ditemukan di Pantai Pailus ditemukan 1 Kelas Echinodermata yaitu Holothuridea yang terdiri dari 3 spesies, yaitu Holothuria atra, Holothuria scabra, dan Holothuria leucospilota. Hasil penelitian menunjukkan kelimpahan individu tertinggi penelitian di Pantai Krakal adalah Ophiocoma scolopendrina (7,05 ind/m²),sedangkan kelimpahan individu tertinggi di Pantai Pailus adalah Holothuria scabra (2,13 ind/m²). Echinodermata is a biota that can be found almost in all marine ecosystems. Echinodermata quite abundant presence in the area coral reefs, because it serves as shelter and feed for Echinodermata. In the food chain, Echinodermata has a role as a seston eater or dentrite, and remodel the rest of the organic material. Echinodermata also serves as a bioindicator of water quality parameters. This study aims to determine the abundance of Echinodermata found in Krakal Beach, Gunung Kidul, Yogyakarta and Pailus Beach, Jepara, Central Java. The method used in this research was descriptive method. Sampling in this research used quadrant transect method with size 1x1m. The results of observation on Krakal Beach found 2 classes of Echinodermata phylum, among others 3 species of Ophiuroidea namely Ophiocoma erinaceus, Ophiocoma scolopendrina, Ophiarachna affinis, and 3 species of Echinoidea is Echinometra viridis, Echinometra oblonga, and Stomopneustes variolaris. While the type of Echinodermata found in Pailus Beach found 1 Class Echinodermata is Holothuridea consisting of 3 species, namely Holothuria atra, Holothuria scabra, and Holothuria leucospilota.

Abstract:
碩士<br>國立臺灣大學<br>漁業科學研究所<br>83<br>Reproduction periodicities of Anthocidaris crassispina and Stomopneustes variolaris, around the coastal of Yeh-liu in northern Taiwan(25.1。N), were studies by compared with monthly gonad index and histological examination of gonads from Mar. to Dec. 1994. The spawning period of A. crassispina was from Jul. to Sep., between the populations of Japan (32.8。N, Jul.- Aug.) and Hong Kong (22.2。N, Jun.-Oct.). The spawning season of S. variolaris was from Jun. to Oct., longer than South African ( 30.5。S, Dec.-Jan.). Spawning of both sea urchins was initiated by injection of 0.5M KCI solution. Eggs were rinsed with filt- ered seawater, fertilization with a dilute suspension of sperm, and rinsed several times with filtered seawater (35 ppt S). After hatching, the swimming, pyramidal-shaped larvae were transferred to 2L beakers filled with 1.5L of filtered seawater. The seawater in the culture beakers were continuously rotated ( 10 rpm ) at 25 ℃ in a dark room and renewed every day. After changed the seawater, the microalgae Isochrysis galbana was used as food for larvae at concentrations of 104 cells / ml. After 6 -arms stage, larvae were processed by feeding different alga species, I. galbana, Tetraselmis chui and Skeletonema costatum, at different concentrations of 104, 5*104 and 105 cells/ml. The larvae of A. crassispina, fed on I. galbana, grew best, and better at higher algal concentration ( 105 cells/ml). In contrast, the S. variolaris larvae had the best growth at lower algal concentration ( 104 cells / ml ) and no significant difference between different algal treatments. The larvae of A. crassispina, fed with 105 cells / ml of I. galbana at 24 ℃, reached the 8-arms stage 12d after fertilization. The ruidiment and 2 pedicellariae appeared at 19 d. The larvae of S. variolaris,reared at 104 cells/ml of I. galbana at 25 ℃, reached the 12-arms at 37d. The larvae with ruidiment were found at 39d.

Abstract:
Ten species of shallow water echinoid are found on the subtropical east coast of South Africa. Although their distributions are patchy, the most common species, Echinometra mathaei, stomopneustes variolaris and Diadema savignyi, are nontheless conspicuous components of intertidal communities on this coast. As little was known about these three species, the overall intention of this study was to provide some fundemental information on their biology and ecology. For the purposes of achieving this aim a life history approach was adopted, where the relative investments by each species in growth, maintenance and reproduction were investigated and compared. These patterns of investment were then related to the habitat occupied by each species, in an attempt to identify the selective forces which may have been implicated in shaping their life histories. It was apparent from the results of investigations conducted between January 1991 and June 1993 that there were distinct differences in the patterns of investment in growth, maintenance and reproduction between the three species. The life history of S. variolaris, which occupied exposed habitats in the lower intertidal, was characterised by a large investment in maintenance, lower reproductive output, slower growth and a longer lifespan, relative to the other two species. In contrast, Q. savignyi, which inhabited less exposed mid-shore pools, had a relatively higher reproductive output, more rapid growth, a smaller investment in maintenance and a shorter lifespan. While selection ln S. variolaris and Q. savignyi appears to favour survival and reproduction respectively, the life history of E. mathaei, a species which also occupies mid-shore pools, was balanced between these two extremes, allocating sufficient resources to maintenance to permit tolerance of harsh physical conditions while still making a moderate investment in reproduction over a lifespan of intermediate duration. The predictions generated by the r-K selection and "bet hedging" theories of life history evolution, were applied in the process of speculating on the selective forces which may have shaped these life histories. However, it was found that neither set of predictions and associated selective forces could adequately explain the observed life histories. Rather, it seemed that the life histories of the three species represented evolved responses to the direct and indirect effects of exposure to wave action and sand movements which dominate the intertidal environment on the South African east coast. In the exposed lower intertidal, unpredictable recruitment, drag and impact forces associated with wave action, which impose limits to body size and necessitate a large investment in maintenance to ensure survival, select for slow growth, low reproductive output and high longevity. In contrast reproduction and growth of species occupying the more sheltered mid-shore pool habitats would be less effected by the demands of maintenance investment or limits to body size. In addition predictable recruitment in the mid-shore, would obviate the need for long life in order to ensure a contribution to future generations.<br>Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 1993.

Abstract:
Cd levels were measured in three different body compartments of the echinoid Stomopneustes variolaris after exposure to concentrations of 5 ug 1l, 20 ug 1l and 50 ug 1l Cd for a period of two weeks. The body compartments investigated included the intestine, gonads and skeleton. The gonads did not exhibit dose-dependent bioaccumulation. The levels of cadmium in the intestine and skeleton were significantly different between the treatments, suggesting that dose dependent bioaccumulation had occurred in these compartments (except in the skeleton where higher levels -were recorded for those exposed to 20 ug 1l than those exposed to 50 ug 1l) The levels recorded in the intestine were higher than those recorded in the gonads and skeleton at the higher Cd exposures of 20 and 50 ug 1i. The levels accumulated in the gonads and skeleton were not significantly different from each other. A separate group, exposed to 20 ug 1`1Cd over a period of two weeks, was placed in uncontaminated seawater to determine if the echinoids were capable of bioremediation. Bioremediation was found to lower the Cd levels in the gonads, but not in the intestine and skeleton. Cadmium levels for the three body compartments were also recorded from specimens collected from the field, indicating the presence of this element in the environment. In addition to using atomic absorption spectroscopy (AAS), energy dispersive X-ray analysis (EDX) was used as a comparative technique to detect the presence of Cd in the skeleton of the urchin. Cadmium was detected in the skeleton with AAS, but not with EDX. S. variolaris proved to be a capable biomonitor of Cd contamination.<br>Thesis (M.Sc.Eng.)-University of Durban-Westville, 2002.
