This review covers the biology and ecology of the three genera of Perna: P. viridis, P. canaliculatus and P. perna. An overview is given of the technological status of culture systems with emphasis being laid on the description of advanced culture techniques such as raft and longline systems. Postharvest handling aspects for preservation of live and processed mussels are presented in detail and public health and economic aspects of the mussel culture industry are described.
An account is given of the studies on the culture of the freshwater mussel Anodonta woodiana with fishes in fertilized ponds which have been conducted at the Freshwater Aquaculture Center, CLSU, Nueva Ecija, Philippines.
The introduction of green mussels (Perna viridis ) is Padre viridis) in Padre Burgos, Philippines, is described. Spat settlement, although small so far, is a strong positive indication that mussel culture is feasible in the area. Upon successful completion of the project, the results will be used to set up guidelines for other sites not yet obtaining spat settlement and also to assist in locating other areas suitable for mussel culture.
The Central Marine Fisheries Research Institute (CMFRI) in India developed bivalve farming technologies in the 1970s, but these were not widely adopted at the time. In 1993, CMFRI undertook an action research program to encourage farming of edible oysters (Crassostrea madrasensis), mussels (Perna viridis and Perna indica), clams (Paphia malabarica) and pearls (Pinctada fucata) along the southwest coast of India.
Capture fisheries and aquaculture provide a large quantity of bivalve molluscs for human consumption in Thailand each year. The existing information on trace elements in these bivalves is fragmentary and contradictory. This paper reports data for eight metals (cadmium, chromium, copper, iron, lead, nickel, mercury and zinc) in the four major species marketed. These are hte clam Paphia undulata, the cockle Anadara granosa, the green mussel Perna viridis and the rock oyster Crassostrea commercials.
The slipper oyster (talaba) and the green mussel (tahong) are the only mollusc species farmed in the Philippines. They are farmed for their meat, and consumption is mainly for the domestic market. The Western Visayas region, situated in central Philippines (Fig. 1), is one of the major sources of oysters and mussels. Natural population of oysters and mussels along rivers and bays and the need to augment income from fishing have led to the proliferation of oyster and mussel farms. Their farming started as early as the 1950s.
Freshwater pearl culture is growing as a source of employment and income in many Southeast Asian countries. Bangladesh, Thailand, the Philippines and Vietnam have initiated freshwater pearl culture projects in recent years. In India, the Central Institute of Freshwater Aquaculture is carrying out research on identification of suitable local pearl mussel species (Genera Lamellidens)defining appropriate surgical implantation procedures, developing post-operative care procedures and captive pond culture of mussels.
The paper reviews freshwater and coastal aquaculture practices in Thailand, and compares the productivity, costs, and benefits across various types of cultivation and various intensities of production. The paper is based on data that were collected in surveys conducted during 1998-2001 by the Department of Fisheries (DOF), Thailand and the WorldFish Center. More than 22% of Thailand's fish supply comes from aquaculture, with coastal aquaculture accounting for more than 88% of this in terms of value.
The Food and Agriculture Organization of the United Nations provided funding in support of the development of micro-enterprises in Banate Bay, Iloilo and Southern Iloilo. This project was implemented by the University of the Philippines in the Visayas in coordination with the Banate Bay Resource Management Council, Inc. and the Southern Iloilo Coastal Resource Management Council.
Manila rope was used for the hanging method of green mussel culture. The monthly density of spat on rope, their rate of growth and environmental factors in the experimental area were determined.
