Suitability of Habitats for Growth of Black-Lip and Silver-Lip Pearl Oysters Final, June 2008GLOSSARY‰ – parts per thousand (salinity).°C – degree centigrade.Atoll – a ring-shaped coral reef that fully or partially encloses a lagoon and is surrounded byopen sea.Black-lip pearl oyster – Pinctada margaritifera.Chaplet – dropper rope connected to a longline from which juvenile or adult oysters areattached.GBR – Great Barrier Reef.Hoa - shallow channels separating individual narrow islands on atoll reefs.Motu - narrow islands on atoll reefs.Picoplankters - Very small, single-celled planktonic plants or animals between 0.2 - 2.0 µmlong.POM – particulate organic matter.Pseudoatoll - coral reef surrounding an inner lagoon with several islands.Pseudofaeces - Organic waste produced by filter feeding molluscs which includes faeces andrejected food particles.SFG - Scope for Growth - Energy available to sexually mature animals for growth andreproduction.Silver-lip pearl oyster - Pinctada maxima.Spat – recently-settled juvenile mollusc.SPM – suspended particulate matter.Turbidity - a measure of the degree to which the water looses its clarity due to the presenceof suspended particulates.The Ecology Lab Pty Ltd – Marine and Freshwater Studies Page 1
Suitability of Habitats for Growth of Black-Lip and Silver-Lip Pearl Oysters Final, June 20081.0 INTRODUCTIONThe European Union has recently funded a project entitled ‘Stimulating investment in pearlfarming in the Solomon Islands’. The primary objective of this project is to provide offshorepearl companies with sufficient information to determine the potential for long-terminvestment in pearl farming in the Solomon Islands. Information on the following aspects iscurrently being compiled for this project:• Publications on the availability and culture of black-lip pear oysters in the SolomonIslands;• Availability and quality of silver-lip pearl oyster resources in the Solomon Islands;• Availability of suitable habitats and environmental conditions for the growth of black-lipand silver-lip pearl oysters in the Solomon Islands and pearl-producing regions of theSouth Pacific;• The investment climate in the Solomon Islands;• Policy guidelines for the development of environmentally and financially sustainablepearl farming in the Solomon Islands; and• Offshore pearl companies most likely to consider investing in pearl farming in theSolomon Islands.In February 2007, The World Fish Centre commissioned The Ecology Lab Pty Ltd to providea number of consultancy services for the EU project, including the preparation of thefollowing report comparing coral reef lagoons and habitats suitable for growing black-lipand white-lip pearl oysters in the Solomon Islands with other locations in the Pacific,specifically French Polynesia, Cook Islands, Australia, Fiji, Vanuatu and Papua New Guinea.A comparison of this type requires an understanding of the environmental needs of eachspecies and a sound knowledge of the environmental conditions prevailing at existing farmlocations, the different types of coral reef and lagoon habitats in the specified regions andtheir prevailing environmental conditions and the influence of the natural environment onthe various stages of culture. This report addresses each of these aspects in turn and drawsconclusions about the suitability of the habitats available for growing pearl oysters in theSolomon Islands relative to those in the other Pacific regions.The Ecology Lab Pty Ltd – Marine and Freshwater Studies Page 2
