The coral reef acts as a barrier to reduce the force of wave action upon the land. In addition. the reef provides a natural habitat for a variety of plant and animal life which interact with the environment to form the most complex ecosystem in our world today. The people of Guam utilize the reef for recreational purposes as well as a source of food. -

BAB IV HASIL PENELITIAN DAN PEMBAHASAN A. Hasil Penelitian dan Pembahasan Tahap 1 1. Kondisi Faktor Abiotik Ekosistem perairan dapat dipengaruhi oleh suatu kesatuan faktor lingkungan, yaitu biotik dan abiotik. Faktor abiotik merupakan faktor alam non-organisme yang mempengaruhi proses perkembangan dan pertumbuhan makhluk hidup. Dalam penelitian ini, dilakukan analisis faktor abiotik berupa faktor kimia dan fisika. Faktor kimia meliputi derajat keasaman (pH). Sedangkan faktor fisika meliputi suhu dan salinitas air laut. Hasil pengukuran suhu, salinitas, dan pH dapat dilihat sebagai tabel berikut: Tabel 4.1 Faktor Abiotik Pantai Peh Pulo Kabupaten Blitar Faktor Abiotik No. Letak Substrat Suhu Salinitas Ph P1 29,8 20 7 Berbatu dan Berpasir S1 1.

Dallol area is situated in the northern most part of the Eastern African Rift system. The studied coral outcrops are aligned along the northwestern margin of the Afar rift. This research focused on the investigation of systematics of corals and associated fossils of mollusca, echinoidea, ostracoda and foraminifera together with the reconstruction of past environmental conditions. Different scientific methods were followed in order to achieve the objectives of the study. These are detailed insitu morphological descriptions; field observations and measurements; laboratory preparations and microscopic examinations; comparison of the described specimens with type specimens; and paleoecological calculations using PAST-3 software. Total of 164 fossil and 9 sediment samples are collected from the field and examined. The Dallol corals are classified into 12 Families, 29 Genera and 60 Species. -

Amornsak Sawusdee1 (1) The Center of Academic Service, Walailak University, Tha Sala, Nakhon Si Thammarat, 80160 The results of observation of catching BSC by using collapsible crab trap and floating seine. According to the observation of aquatic animal which has been caught by main BSC fishing gears; floating seine and collapsible crab trap, there were 176 kind of aquatic animals. The catch aquatic animals are shown in the table1. In this study, aquatic animal was classified into 11 Groups; Blue Swimming Crab (Portunus Pelagicus), Coelenterata (coral animals, true jellies, sea anemones, sea pens), Helcionelloida (clam, bivalve, gastropod), Cephalopoda (sqiud, octopus), Chelicerata (horseshoe crab), Hoplocari(stomatopods), Decapod (shrimp), Anomura (hermit crab), Brachyura (crab), Echinoderm (sea cucambers, sea stars, sea urchins), Vertebrata (fish). Vertebrata was the main group that was captured by BSC fishing gears, more than 70 species. Next are Helcionelloida and Helcionelloida 38 species and 29 species respectively. The sample that has been classified were photographed and attached in appendix 1. However, some species were classified as unknow which are under the classification process and reconcile. There were 89 species that were captured by floating seine. The 3 main group that were captured by this fishing gear are Vertebrata (34 species), Brachyura (20 species) Helcionelloida and Echinoderm (10 Species). On the other hand, there were 129 species that were captured by collapsible crab trap. -
CONE SHELLS - CONIDAE MNHN Koumac 2018
Living Seashells of the Tropical Indo-Pacific Photographic guide with 1500+ species covered Andrey Ryanskiy INTRODUCTION, COPYRIGHT, ACKNOWLEDGMENTS INTRODUCTION Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with ocean - divers, snorkelers, beach goers - all of them often find in the seas not empty shells, but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, Marshall Islands and Guam. Inside the book: • Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book ACKNOWLEDGMENTS The significant part of photographs in this book were made by Jeanette Johnson and Scott Johnson during the decades of diving and exploring the beautiful reefs of Indo-Pacific from Indonesia and Philippines to Hawaii and Solomons. They provided to readers not only the great photos but also in-depth knowledge of the fascinating world of living seashells. Sincere thanks to Philippe Bouchet, National Museum of Natural History (Paris), for inviting the author to participate in the La Planete Revisitee expedition program and permission to use some of the NMNH photos. -

It is an economically crucial species; however, its population has been declining due to overfishing and overexploitation. Hence, we developed a novel polyculture and water-flow method for mass production of this species. Furthermore, the findings from this work also uncover the potentiality of L. canarium in integrated multitrophic aquaculture (IMTA) and its implication for aquaculture and resource restoration.

GENERA LAMBIS- TEREBELLUM, TIBIA AND RIMELLA N. V. SuBBA RAO Zoological Survey of India, Calcutta ABSTRACT This paper is the concluding part on the Strombidae of Indian Soas and the first comprehensive report on tlie species of this region. Fourteen species belonging to four genera namely, Lambis, Tibia, Terebellum and Rimella are recorded from the Indian Ocean. Two species of Rimella are reported here for the first time from Indian Seas. INTRODUCTION THE FAMILY STROMBIDAE is represented by five genera namely, Strombus, Lambis, Terebellum, Tibia and Rimella in the Indian Seas. The collections in the Zoological Survey of India are well represented in having all the genera. The genus Strombus was dealt with in a previous paper (Subba Rao, 1971). The present paper deals with the remaining four genera namely, Lambis, Tibia, Terebellum and Rimella. The author is grateful to Dr. S.
