    A study of the trade in smoked-dried fish from West Africa to the United Kingdom. 2003

    The quantity of smoked fish from West Africa entering the United Kingdom is estimated to be in the region of 500 tonnes per year with a retail value of £5.8 to £9.35 million. Approximately 120 tonnes arrives by airfreight, a significant proportion of the remainder is thought to be entering as accompanied baggage and product is also arriving overland from mainland Europe. Nigeria currently exports approximately 5 tonnes of smoked fish per month as airfreight - 60 tonnes per annum. Most of this is via Gatwick Airport. The other major exporting countries are Ghana, the Ivory Coast and Cameroon. Approximately 1 in 4 consignments of air freighted smoked fish are detained for some reason at port of entry. Of these 70% are destroyed. This is approximately 17.5% of consignments and equivalent to 20 tonnes of product with a retail value of £240 000 to £390 000. The main reasons for detention are:Packaging is inadequate – re-used computer or TV boxes, in poor condition, newspaper or baskets are used for packing the fish; Insect infestation;Establishment number stapled on the box rather than written on; Health certificates not filled in correctly; Smoked fish included among other goods and not declared. Draft best practice guidelines have been drawn up focusing on the control of insect infestation, mould growth, the use of correct packaging and the preparation and processing of necessary paperwork for export/import.

    Technical reports - product by product development from Nile Perch (summary table) 1988
    Also available in:

    Since dairy meal is becoming increasingly expensive in Kenya and threatens the fish rearing industry, a systematic study was initiated on the possibility of using aquatic plants and Nile perch silage. The water plants, Azolla niloticus, Lemna perpusilla and Pistia striatotis were tested as a fishmeal for Tilapia zillii and riverine fishes. Low growth rates were achieved in the tilapias. The value of the Azolla protein in fish diet is discussed in relation to dietary requirement in cultured fish. This study demonstrates that the water plant Azolla niloticus together with Nile perch silage as a supplement can be used as a complete diet for cultured fish. It is hoped that the project will help provide detailed information on the nutritional value of the water plant Azolla niloticus and its long-term susceptibility to various inclusions as a complete feed, and conduct least cost feed formulations to make recommendations as to the maximum inclusion levels.

    Giant Clams in the Maldives- A Stock Assessment and Study of Their Potential for Culture-BOBP/WP/72 1991
    Also available in:

    Tuna fishing is the major fisheries activity in the Maldives. However, fishing for nontraditional organisms is becoming popular, as it provides fishermen with new areas of employment or alternatives when tuna fishing is poor. One non-traditional fishery in the Maldives is that for giant clam. This fishery is only a year old, but so considerably has the resourcebeen exploited that different non-fishery professionals — tourist resort owners, divers and, of course, environmentalists — have alread y shown great concern about its long term effects. It was this concern that led to the Ministry of Fisheries and Agriculture undertaking an assessment of the status of giant clams in the Maldives through their Reef Fish Research and Resources Survey Project (RAS/88/007). The assessment was executed by the Food and Agriculture Organization of the United Nations through the Bay of Bengal Programme, with funding from the United Nations Development Programme. This paper is based on the report su bmitted by the consultant to the Government of Maldives in April 1991 and describes the findings of the assessment and discusses the possibility of developing a viable mariculture project to ensure a continued existence of the giant clam in the Maldives. The author wishes to thank all the team at the Marine Research Section of the Ministry of Fisheries, particularly Maizan Hassan Maniku and Charles Allism, for their detailed backgound information, Hassan Shakeel of MRS, for putting up with man y questions and providing logistic assistance, Bill Allison for field assistance in counting of clams and John Lucas for helpful comments on the final report.
