Heavy metal concentrations (CD, CU, NI, PB, FE AND ZN)in the different soft tissues and shells of pholas orientalis collected from Sekinchan and Pantai Remis, Selangor.

The clam, Pholas orientaliswere collected from the mudflats of Sekinchan and Pantai Remis, and their soft tissues were dissected into crystalline style, siphon, mantle and foot; while the shells were divided into three parts namely the umbo, smooth part (anterior of shell) and rough part (posterior of shell). Generally, the results show that: 1) All the different soft tissues accumulated higher concentrations of essential Cu, Zn and Fe when compared to those in the hard tissues; 2) On the other hand, the three hard tissues accumulated higher concentrations of nonessential Cd, Ni and Pb than those in the soft tissues. These results reflected a different binding affinity for the two different metal groups between the soft and the hard tissues; 3) The different levels of metals found within the four different tissues indicated that metal detoxification mechanism in the different organs are not similar in P. orientalis. The ecological distribution and metal distribution in the different tissues of P. orientaliscan serve as a baseline for future reference

Short communication: Effects of induced spawning on early development in snout otter clam, Lutraria philippinarum (Deshayes, 1854) (Bivalvia: Mactridae)

Throughout the world, bivalves play an important role in the national economy of many countries. In 2005, the contribution of bivalves to the total global trade of fish and fishery products was approximately US$ 78.9 billion. Though the contribution of the overall bivalve production to aquaculture increased, production from wild harvests exhibited a downward trend. Increased fishing efforts from rapidly growing population, habitat destruction, environmental changes, pollution, high seafood and shell trade global demand are the factors which lead to the decline of many mollusk resources. One of the commercially important bivalves which showed a declining catch is Lutraria philippinarum. ... In the case of Lutraria philippinarum, a reliable method of spawning induction and description of its larval development are yet to be developed. Thus, this study deals with the stages of early development in Lutraria philippinarum and the effects of induced spawning on its early development. Results of this study will add to the dearth of larval development and biology literatures on L. philippinarum

Studies on the fishery and biology of the Malabar sole, Cynoglossus semifasciatus Day

The Malabar sole, Cynoglossus semifasciatus Day, is a fish of considerable commercial importance along the Malabar Coast. Apart from the fact that it ranks often next only to the sardine and the mackerel in total landings, it is the only fish available on this coast during certain periods of the year. The species was therefore taken up for detailed investigations in the programme of the Central Marine Fisheries Research Sub-Station at Calicut. The work was commenced in April, 1948, and the present paper embodies the results of these investigations up to March, 1952

Diversitas dan Ekologi Makan Burung Pantai di Kawasan Pantai Baru, Kabupaten Deli Serdang Sumatera Utara

Pantai Baru area of Deli Serdang is located on the East Coast of Sumatera that has been as Important Bird Area (IBA). The wetland type of this area are consisted of ponds, mangroves, and mudflat that occupied by shorebirds both for feeding and resting area. This study aimed to analyze the diversity and potential food of shorebirds Pantai Baru area. Concentration count method and Corer methord were used to collect the shorebirds and macrozoobenthos data. The study found 19 species of shorebirds and 21 species of macrozoobenthos. The diversity index of shorebirds ranged from 1.89 to 2.50 on medium category with the evenness index ranged from 0.84 to 0.97 with high category, while diversity index of macrozoobenthos was 1.09 on medium category with evenness index 0.36 on small category

Biological Aspects And The Development Of Larvae And Juvenile Of The Angelwing Clam Pholas Orientalis (Gmelin, 1791)

Di dalam persekitaran semulajadi di Kuala Kedah, taburan kuantitatif Pholas orientalis telah ditentukan dengan menggunakan kuadrat bersaiz 1m2. In the natural bed of Kuala Kedah, the quantitative distribution of Pholas orientalis was estimated (from July 2006 till July 2007) using quadrate of 1m2

Taxonomic study of edible bivalve from selected division of Sarawak, Malaysia.

The diversity of edible bivalve was conducted from August 2010 to July 2011 covering eight divisions i.e., Kuching, Sarikei, Sibu, Mukah, Bintulu, Miri, Limbang and Lawas of Sarawak, Malaysia. Samples were collected from native market and fishing village during the study period. All edible bivalves inhabit either in brackish or marine environment and comprised 19 species from 10 families namely Meretrix meretrix, M. lyrata, Paphia undulata, Circe scripta, Solen regularies, Solen lamarckii, Pharella acutidens, Amusium pleuronectes, Anadara granosa, Pholas orientalis, Gluconome virens, Placuna placenta, Crassotrea lugubris, Isognomon ephippium, Polymesoda erosa, P. bengalensis, P. expansa, Anadonta woodina and Pilsbryoconcha exilis. The diversity of edible bivalves was found highest in Kuching and Bintulu compared to other divisions studied in Sarawak. The bivalve species at Sarawak could have economic potentiality in terms of protein source, livelihoods of local tribes and economic value. Study suggests that if the high conservation and management of edible bivalve diversity could establish in the coastal and wetland area of Sarawak, a remarkable and vast economic return could achieve

Diversity of edible mollusc (Gastropoda and Bivalve) at selected division of Sarawak, Malaysia.

Diversity of edible mollusc was studied at eight divisions of Sarawak from August 2010 to May 2011. At each division, diversity and number of species were collected from road site selling out lets and local wet markets. Total number of mollusc was comprised of 29 species namely Solen regularies, S. lamarckii, Pharella acutidens, Anadara granosa, Pholas orientalis, Gluconome virens, Circe scripta, Anodonta woodina, Paphia undulata, Amusium pleuronectes, Meretrix meretrix, M. lyrata, Polymesoda bengalensis, P. erosa and P. expansa for bivalve and Cerithidea rizophorarum, C. obtusa, Telescopium telescopium, Clithon retropictus, Nerita articulate, N. chamaeleon, N. albicilla, Ellobium aurisjuda, Trochus radiates, Planaxis sulcatus, Monodonta labio, Turbo crasus, Thais aculate and Melo melo for gastropod. The species number of bivalve was recorded highest (15 species) in mollusc group from Sarawak. Mollusc diversity was found highest (14 species) in Bintulu and lowest (1 species) in the division of Sarikei. From this study, there is a wide chance of research to further explore both on the possibility of commercial value and ecosystem conservation

A code list of common marine living resources of the Indian Seas (Revised Edition)

The Central Marine Fisheries Research Institute, Cochin is the pioneer national establishment primarily engaged in marine fisheries research in the country. As a programme of dissemination of information the Institute published a code list of common marine living resources of the Indian seas in 1983. However, considerable changes have since occurred in the nomenclature of many of the genera, families and species of fishes. Hence it is felt that there is an urgent need to revise the code list incorporating these changes. The present publication is a result of this exercise

Code list of common marine living resources of the Indian Seas (With Revised Version)

The Central Marine Fisheries Research Institute has been estimating marine fish landings along the Indian Coast for the past three decades and the data are being furnished to Central and State Governments, Industry, and national and international agencies. The Institute is also involved with the assessment of our marine fishery resources and management of multispecies harvested by diverse fishing gears. In the years to come, our commercially utilised marine animal and plant resources may cover not only conventional fin-and shell-fishes.but also non-conventional groups, such as mesopelagics, sponges, corals and seaweeds. There are endangered groups, such as marine mammals and turtles, which are protected under Wildlife Act. They occur as incidental catches or are 'occasionally stranded and these need monitoring

Macro Flora & Fauna of the Gulf of Mannar a checklist

The Gulf of Mannar (GoM) located along the south eastern tip of India falls in the Indo-Pacific realm and is one of the richest regions in the world from a marine biodiversity perspective. The region has a distinctive socio-economic and cultural profile shaped by its geography. It has an ancient maritime history and was famous for the production of pearls, an important item in trade with the Roman Empire as early as the first century AD. Rameshwaram along the GoM with its links to the legend Ramayana is an important pilgrim centre. The region has been and continues to be famous for its production of Indian sacred chanks. It has unique ecosystems mainly consisting of coral reefs, sea grass beds, salt marshes and mangroves which constitute important habitats for many species of commercially important finfishes and shellfishes. The GoM was established as a Biosphere Reserve (the first marine biosphere reserve in south and south east Asia) by 1989 by the Indian Government and the state of Tamil Nadu. A biosphere reserve is an area that is indented to secure the fundamental diversity of life in a region while continuing to advocate in economic growth. The overall objective of this Marine Biosphere Reserve is to conserve the Gulf of Mannar's globally significant assemblage of coastal and marine biodiversity and to integrate biodiversity conservation into coastal zone management plans. Thus, the GoM in addition to being a national priority also assumes global significance
