New Caledonia, which is surrounded by one of the largest lagoons in the world, is a good reservoir of the Pacific species of trochus (Trochus niloticus). The shell of this large marine gastropod yields one of the thickest, most beautiful mother-of-pearls available on the world market. This article gives a brief account of the trochus resource found in the island.
In Mexico, the Direccion de Fomento Pesquero of the State Government of Sonora has financed a project for a shell¬fish hatchery and nursery complex at Bahia Kino on the Gulf of California which began production in January 1984. The project is part of a scheme to supplement fished products with aquaculture produce -- shrimp, fish and shellfish. There is a large but declining shrimp fishery in Sonora (over 14,000 tonnes worth nearly $200 million were landed in the 1983-1984 season).
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.
An account is given of a development project for the production of cockle seed and subsequent transfer of thetechnology used to the fisherfolk of Kuala Juru for the setting up of hatcheries for bivalve seed production.
Anadarinids are marine bivalve molluscs harvested commercially and on a subsistence basis in many warm temperate to tropical countries. They are frequently called mangrove cockles, blood cockles or simply cockles, although true cockles belong to a different bivalve family. In Asia the anadarinid cockles are known locally as kerang (Malay), hoy kreng (Thai) and si-ham (Cantonese). This article gives a brief account of the culture and biology of cockles in the Asian region.
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 overall objective of the project is the reduction of poverty in rural areas of Solomon Islands through creation of livelihoods based on sustainable aquaculture. This fits within the over-arching goals of the WorldFish Center in the Pacific to reduce poverty and hunger in rural communities, and with the Ministry of Fisheries and Marine Resources (MFMR) to stimulate rural development and to develop aquaculture.
Food safety standards in the seafood trade between developing country exporters and developed country importers have been a topic of much discussion in the trade literature. As an important source of foreign currency earnings and employment for many lower income developing countries, stricter safety standards in seafood may have the potential to pose barriers to trade, especially for many Asian seafood exporters. This paper investigates the impact of stricter drug residue (chloramphenicol) standards on crustacean imports to Canada, the EU15, Japan, and the United States.
Relative biomass per recruit of adult (i.e. sexually mature) fin to shellfish is shown to help in identifying levels of fishing mortality likely to lead to recruitment overfishing. This is illustrated with data from a Malaysian penaeid shrimp fishery.
