The catch-effort relationship of the River Nile is Complicated by such factors as changes in water level and hydrology as well as spawning movements of the fish, which result in uneven distribution of the fish and fishing. The effects ofdam construction on the ecology of the fish fauna are considered, with particular reference to the effects of the Faraskour dam on the river fishery.

Shellfish production in Thailand has ranged between 50,000 and 300,000 mt over the past twenty years, with recent production around 120,000 mt/yr. Major species are green (Perna viridis ) and horse mussels (Modiolus senhausenii ) making some 60% of total production. The other main types, in order, are short-necked clams (Paphia undulata ) ark shells (Andara granosa ) and oysters (Crassostrea sp.). Culture practices account for 80% of green mussel, cockle and oyster production.

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.
