Processing and marketing of fish with special reference to export of pelagic fish and fish products

The paper describes the world tuna fishery, industry and markets and the trends for its future development. The prospects for developing a tuna export industry in Sri Lanka are discussed. Suggestions are given as to products composition, international co-operation and utilization of available processing facilities. The need for industry and export support is stressed, and it is concluded that preparations for the development should start well in time.

The role of women in fisheries activities in some selected fishing villages in the southern zone of Kainji Lake basin

Questionnaires containing 39 questions were prepared and administered to 50 women in ten fishing villages in the Southern Kainji Lake Basin to assess the level of women participation in fisheries activities. Results showed that 100% of the women interviewed were involved in fisheries activities and the following factors were considered. Age group between 20-30 years was 18%; 31-40 years; 30%; and above 40 years had the highest percentage of 40%. Also 98% of the women involve in fisheries activities were married while only 2% were not married. Muslin women constituted 82% while 18% were Christians. About 70% of Hausas were involved: no Igbos and Yorubas, while 30% were other tribes, which included Ijaws, Isokos and Urohobos. The percentage of women without education amounted to 62%, those women with Koranic education accounted for 22%, 14% had primary education while only 2% had secondary education. Few women were directly involved in fishing and statistical analysis showed that there was insignificant difference from village to village. All the women (100%) were involved in fish processing and storage (preservation) before sale. Only 26% of the women were not involved in fish marketing. Also 26% of the women made profits ranging from N500 to N1,000 per week, 24% make N1,000 to N1,500 per week, 12% made N1,500 to N2,000 and 38% made profit above N2,000. Statistical analysis showed that there was a significant difference in the profit made by the women (P<0.05) from the foregoing, women were actively involved in all fisheries activities

Socio-economic implications of the fish export trade on the fishers and fisheries of Lake Victoria in Uganda

The purpose of this study was to investigate the implications of the fish export trade on the fishers and the fisheries resources of Lake Victoria, Uganda with respect to sustainability. Eight fish processing factories and ninety fishers were qualitatively investigated. Socio-economic characteristics of fishers and the economic characteristics of fish factories formed a basis for the analysis. Results of the research indicate that there is a relationship between the growth in fish export trade, particularly the growth in industrial fish processing (for export) and declining fisheries resources of the lake. However, whether or not that impact is positive or negative, and to what extent there is an impact, is highly dependent upon the underlying socio-economic considerations of the fishers to the process. The fish-ban imposed by the European Union countries was particularly decried by fishers and factory owners as the main cause for the present poverty among the fishers. Fundamentally, several conflicting issues: ecological, physical and economic activities are a threat to the sustainability of the Lake Victoria fisheries, and for all that depend on and interact with the lake. There is urgent need to address the immediate issue of the growing riparian population and the global fish trade, to educate and train all the relevant actors in appropriate fisheries management techniques. Attitudes of fishers towards the fish factory developments are positive and this is a way forward for co-management for the sustainability of the fisheries resource.

Multidirectional movements of sportfish species between an estuarine no-take zone and surrounding waters of the Indian River Lagoon, Florida

We examined movement patterns of sportfish that were tagged in the northern Indian River Lagoon, Florida, between 1990 and 1999 to assess the degree of fish exchange between an estuarine no-take zone (NTZ) and surrounding waters. The tagged f ish were from seven species: red drum (Sciaenops ocellatus); black drum (Pogonias cromis); sheepshead (Archosargus probatocephalus); common snook (Centropomus undecimalis); spotted seatrout (Cynoscion nebulosus); bull shark (Carcharhinus leucas); and crevalle jack (Caranx hippos). A total of 403 tagged fish were recaptured during the study period, including 65 individuals that emigrated from the NTZ and 16 individuals that immigrated into the NTZ from surrounding waters of the lagoon. Migration distances between the original tagging location and the sites where emigrating fish were recaptured were from 0 to 150 km, and these migration distances appeared to be influenced by the proximity of the NTZ to spawning areas or other habitats that are important to specific life-history stages of individual species. Fish that immigrated into the NTZ moved distances ranging from approximately 10 to 75 km. Recapture rates for sportfish species that migrated across the NTZ boundary suggested that more individuals may move into the protected habitats than move out. These data demonstrated that although this estuarine no-take reserve can protect species from fishing, it may also serve to extract exploitable individuals from surrounding fisheries; therefore, if the no-take reserve does function to replenish surrounding fisheries, then increased egg production and larval export may be more important mechanisms of replenishment than the spillover of excess adults from the reserve into fishable areas.

Recent advances in fish processing and product development

There are good possibilities for expanding the consumer sector in both the traditional and nontraditional marine products. Frozen shrimp continues to be the item of highest demand in foreign markets. Individual quick frozen (IQF) prawns which are indeed value added products and have already penetrated international markets elicit export incentive from development agencies like the Marine Products Export Development Authority. With the projected potential of 1.8 lakh tonnes of cephalopods against the current yield of 13,000 tonnes, there are good prospects of increasing exports of frozen squid and cuttlefish. The technology of packing fish in retortable pouches as an alternative to canning has now been perfected. Salted fish mince has good market potential in India and abroad.

The future of shrimp processing industry in India

The future of the shrimp industry in India depends entirely on our export markets. Therefore the future of the industry must be related to the demand for shrimps in foreign markets. The most important market today for India is the United States. In the United States the domestic production of shrimps which was about 112 million pounds in 1950 has increased only slightly to 139.6 million pounds in 1965. However the consumption during the same period increased from 119.5 million pounds to 274.2 million pounds - the gap between home production and consumption is made up by imports.

Socio-economic implications of the fish export trade in Uganda

Implications of the fish export trade on the people and the fisheries resource of Lake Victoria, Uganda were examined. Eight fish processing factories and ninety fishers were analyzed in terms of socio-economic characteristics of fishers and the economic characteristics of fish factories. Results indicated that industrial fish processors in Uganda are presently the main link between the artisanal fisher-folk and the overseas export markets. Their entry into the market has stabilized and expanded the fisher-folk market and average earnings. Fishers attributed improvement in incomes and living standards (76%) to positive changes in the fish market (78%) in the last 5 years (1994-1999). Ugandan fisher-folk communities are not seriously affected by the Nile perch exports (73%) because they normally have easy access to cheap fish at prices much less than urban prices and; depend mainly on alternative fish species of less export value. The price of Nile perch influences positively the price of Tilapia

Study on the quality of beche-de-mer in trade and shrinkage of specimens during processing

The beche-de-mer industry in India is a cent percent export oriented industry being confined to south east coast in Palk Bay and Gulf of Mannar in Tamil Nadu. Chemical quality of 180 trade samples of beche-de-mer of four sizes collected from the beche-de-mer curing centres of Ramanathapuram district was studied. Moisture ranged from 6.2 to 24.4% and sand content from 0.11 to 20.42% for all grades. Mean values of sand content are for grade 1=3.47%, grade 2=4.50%, grade 3=3.68%, grade 4=6.87%. Sodium chloride was almost constant for all grades at 5.7%. TVBN values ranged from 10 to 78.4 mg%. 44 laboratory samples of different grades were prepared following trade practice and examined for chemical quality. Mean moisture values are for grade 1=13.4%, grade 2=12.44%, grade 3=12.62%, grade 4=12.08% and mean values of sand are for grade 1=0.70%, grade 2=0.90%, grade 3=1.16%, grade 4=2.15%. The percentage of shrinkage of the animals ranged from 56% to 60% for dried beche-de-mer of 7.5 cm size and above.

Implications of the industrial fish processing growth for the commercial fishery and fishers in Uganda

The study was undertaken to generate socio-economic information on fish market systems and performance of the industrial processing industry, which will guide the processes leading to modernization of the fisheries sector and, sustainability of Lake Victoria fisheries. The main objective of this study was to evaluate the socio-economic implications of the fish marketing systems with particular emphasis on fish export market in Uganda. The study thus, analysed the socio-economic characteristics of fishers and examinined fish marketing systems and the impacts on the fishing activities, food security, employment opportunities and incomes of fisher-folk communities.

Fish handling, processing and storage in Uganda: the role of the extension worker

The handling and processing of fish in Uganda has until recently been carried out exclusively by the artisanal fishermen and fish processors. Their operations have left much to be desired as the product is often of low quality 'and its keeping time is limited. The handling of fresh fish has been without refrigeration but with the recent establishment of commercial fish processing plants a cold chain of fish distribution is being set up for domestic and export markets. Some of the fishermen are beginning to ice their catch immediately after reaching the shore. It is hoped that fishmongers will increasingly find it more profitable to market their products iced. This will make fish available to a large sector of the population and in the process there will be reduced post-harvest losses.

The Fossil higher plants from the Canal Zone

Fossil flora described in the present report is too limited for purposes of exact correlation, which may be expected to be settled by the marine faunas present at most horizons in the Isthmian region. Accompanying table of distribution will show that from the oldest (Hohio) to the youngest (Gatun) plant-bearing formations there is no observable difference in floral facies. This so-called Oligocence series of formations does not represent any great interval of time. (39 page document)
