Book (series)Pacific oyster farming
A practical manual
2024Also available in:
No results found.The purpose of this manual is to give the reader a foundation of practical knowledge regarding all aspects of Pacific oyster cultivation. It is targeted at new entrants to the market wishing to establish a farm, and existing operators who wish to develop their farms and explore new cultivation techniques. The methodologies described can be applied both to low-tech, low budget, small-scale farming operations and to high-tech, big budget, industrial-scale aquaculture production enterprises. This guide focuses on the functional expertise and technical equipment required to construct and manage an operational farm in the diverse environmental and physical locations in which they can be situated, from the initial stages of finding and selecting a suitable site, to the conclusion of the first production cycle and harvesting the crop. The manual contains a brief introduction which describes the relevance of the species with regards to global aquaculture production figures and how it can form an important part of future food production strategies. Chapter 2 describes the anatomy and biology of Crassostrea gigas and gives an indication as to the environmental conditions in which the species thrives as well as the pathologies and predators that can result in poor health leading to potential mortalities. Chapter 3 deals with all aspects of undertaking a survey of potential oyster farming sites and what data should be collected and examined to assess a site’s suitability, but also which areas are best suited to different cultivation techniques. After this, Chapter 4 introduces the main farming techniques that will be described in detail in the following chapters, which includes off-bottom cultivation, on-bottom cultivation, and suspended cultivation, and gives details of some of the most common cultivation equipment necessary to undertake these operations. The techniques and strategies necessary to procure seed oysters and how to develop them through the nursery stage are also introduced. This includes the basic principles of upwelling, which then leads into Chapter 5, which provides a detailed description of how to build and operate one particular example of a Floating Upwelling System (Flupsy) which is suitable for use in remote but sheltered conditions. Chapters 6, 7 and 8 constitute the main body of the manual and provide an in-depth look into the three major cultivation techniques that this guide concentrates on: “Farming with trestles and bags in the intertidal zone”, “On-bottom cultivation in the intertidal or subtidal zone” and “Offshore longline cultivation”. -
Book (series)Bivalve depuration: fundamental and practical aspects 2008World bivalve production and consumption has increased significantly in recent years, from a combined total for wild catch and aquaculture of approximately 10.7 million tonnes in 1999 to 14 million tonnes in 2006. Furthermore, the development of freight by air and sea and preservation techniques have enabled consumers, in different parts of the world, to enjoy eating bivalves produced in distant waters. Such developments in distribution and trade have in turn led to emerging challenges for consumer protection, particularly in relation to the safety of bivalves from pathogenic micro-organisms. Several species of bivalves are often consumed live or raw (e.g. oysters), or lightly cooked (e.g. mussels) which make them a high risk food product category requiring proper control measures to eliminate or reduce to acceptable levels potential biological, chemical and physical hazards. This document is intended to provide a basic introduction to the public health problems t hat can be associated with shellfish consumption and to provide guidance to the bivalve industry as to how a depuration centre, and the associated systems, should be planned, constructed and operated. It is mainly targeted at new operators or those with limited experience, as well as fishery and public health officers who deal with the bivalve industry. This is of particular importance for several developing countries, where the bivalve industry is expanding quickly with the aim of win ning an ever larger share of the bivalve international market.

Brochure, flyer, fact-sheetProactive approach proved key to survival for the Australasian Pacific oyster industry 2022
Also available in:
No results found.Since 2008 Pacific Oyster Mortality Syndrome (POMS) has emerged as a significant threat to the Pacific oyster industry globally. The disease was first detected in Australia and New Zealand in 2010. The Australian industry is located in three states: New South Wales (NSW), Tasmania and South Australia, which produce up to 10 500 tonnes per year of Pacific oysters, Magallana gigas (previously classified as Crassostrea gigas). Hundreds of growers operate across the three states, using hatchery-reared spat as the basis for their production.
