Accepted 19 April, 2011 A community based study was carried out amongst fisherfolks, fish processors and marketers in Ekenwan village, Ovia North-East Local Government Area of Edo state and Koko village, in Warri North Local Government Area of Delta state. The over all objective of the study was to identify the processing preservation, packaging methods, distribution channels and marketing of cured fish in the study areas, so as ascertain its shelf stability and economic benefits. A total of 103 processors randomly selected were interviewed during the survey. The data obtained were analyzed by descriptive statistics and results obtained revealed that majority of the processors were married women who were not educated beyond secondary school level. Smoking was the main curing method and storage materials for cured fish were baskets, jute bags and plastic drums. Causes of loss on cured fish include insect infestation, rodent attacks, mould attacks and breakage due to packing. Packaging and storage methods improve the shelf life of the cured products and packaging materials includes the use of jute bags, paper bags, baskets and these were stored on top of smoke houses and in kitchens. Land transportation was the major means of distribution using wheel barrows, vehicles and trucks. Processing activities within the study area was found to be lucrative but are constrained by high cost of transportation, processing and labour. Thus, the economics and living standard in processing area was quite low. It is recommended that Government should engage in the rehabilitation of the access routes leading to the processing communities, so as to improve transportation system and facilitate mobility of cured fish. Government via its appropriate agencies should sensitize the processors and transporters against over loading of cured fish so as to limit economic losses due to fragmentation on the curer. Keywords: Fish processing, packaging, Shelf life stability, Distribution, Marketing. INTRODUCTION Fish is a low acid food therefore highly susceptible to pathogenic and enzymatic spoilage (King, 2001). Fish is one of the most perishable of all stable commodities especially in tropical climate regions of the world. If not consumed within one day of capture it becomes unfit for human consumption, unless subjected to some form of processing (Abolagba et al., 1996). In Nigeria, over 80% of fish harvested is preserved by various methods of curing to prolong shelf life and these cured fishery products are highly acceptable by the local consumers (Salawu et al., 2004). Cured fish includes *Corresponding author Email: efeobano2002@yahoo.com those products in which preservation is achieved by reducing moisture or by the addition of chemical preservatives including salt, vinegar or smoke (Whittle, 2002). The principal processing methods are smoking, drying, salting, fermentation, roasting, boiling and frying or any combination of these processes (Adepegba, 2001; Eyo, 2001; Whittle, 2002). Smoking is a method of preserving fish which combines three effects; preservative value of smoke, drying and cooking (Clucas, 1982; Asita and Campbell, 1990). Operations involved in smoking of fish are similar and the method has the effect of imparting pleasant flavour to the product besides the preservative effect of the smoke (Ako and Salihu, 2004; Tull, 1997). The longer fish is smoked, the longer will be the shelf life (Arthur and Osei-Somuah, 2004; Abolagba 104 Int. Res. J. Biotechnol. et al., 2002; Eyo, 2001; Eyabi, 1998). Preservation by drying is effected by lowering the water vapour pressure of the fish to a level which microorganisms can no longer grow (Eyo, 2001; Ako and Salihu, 2004; Bolaji,2005). Salting deslubs the slime on the surface of the fish, which also inactivates the surface bacteria (Abolagba et al., 2006). Common salt (Nacl) retards the activity of bacteria, enzymes and chemicals in fish (Eyo, 2001). The simplicity of salting process, the low cost of production and the ease to which it combines with other preservation methods such as drying and smoking has led to its popularity and extensive use (Berhimpon et al., 1990). Three methods of salting commonly practiced are dry salting, wet salting and brine salting (Whittle, 2002; Eyo, 2001; Clucas 1982). When fish has been processed particularly if traditional methods are employed, the fish is still subjected to many forms of loss and spoilage (Abolagba and Enofe, 2003; Igene et al., 1998). Unless processing is very carefully carried out, physical losses can occur from microbial spoilage, insect infestation and fragmentation (Yu, 1994; Ismail and Wooton, 1992; Ames1992). Post processing and handling of fish has an impact on the shelf life of the product and these include packaging techniques, storage condition and marketing techniques (Abolagba, 2006). Packaging forms an important part of food processing because it facilitates handling during storage and distribution within the market chain (King, 2001). Effective packaging controls insect infestation of dried fish (King 2001; Lawal et al., 1986). Sacks, paper cartons, wooden rackets and bamboo baskets are the most predominantly used artisanal packaging containers (Kings, 2001). The distribution of cured fish in Nigeria is largely by road transportation. This segment is a vital element in the distribution of fish from the processing village to wholesale markets and onward to retail outlets (Kings, 2001). Means of transportation ranges from wheel barrows, motorcycles, taxis, jeeps, pick-up vehicles, buses, trucks, lorries etc. MATERIALS AND METHODS Study Area The study covered two major fish processing communities in Edo and Delta states respectively. In Edo state, the fish processing community was Ekenwan village in Ovia North East Local Government Area which is about 40 km from Benin City. While in Delta state the processing community was Koko village in Warri North local Government Area which is about 34km from Sapele-Warri express road. Sample Size and Sampling Procedure Information was collected by visual observation, use of Focus Group Discussion (FGD) and interviews conducted by a sample survey of fish processors / marketers within the named localities using 120 well structured questionnaires. Of the 120 questionnaires distributed, 103 were properly filled, returned and analyzed. Data Analysis The data obtained were analyzed using simple descriptive statistical methods (frequencies, percentages and chi-square) to test the hypothesis using SPSS statistical package. These parameters were used to analyze cured fish activities such as the processing methods, quantity processed, storage methods/ problems, packaging methods/packaging problems, distribution channels, marketing operation etc. RESULTS The results obtained from survey are as shown in tables below: DISCUSSIONS Study showed that processing and marketing activities of cured fish were carried out mostly by the economically active age range 21- 40 years (65.5%).While age range 41-60 years and 10-20 years had (29.3%) and (5.2%) respectively. The female sexes (majority being married) dominated the sector and are not educated beyond secondary school level (see table 1). This distribution trend could be explained by the fishery sector being besieged by the economically active age ranges and the teenagers are being educated and progressive in outlook with most favourable attitude towards change while older ages have limitations on energy sapping activities. The disparity in gender disposition could be accounted for by occupational emphasis which in fisheries activities apparently restricts the females to processing while the male counterpart predominates in the catch. Educational qualification of respondents showed that majority had primary school and secondary school education respectively. This result revealed that activities of fish processing and marketing are traditional practices that most practitioners get involved in early life to earn a living. This confirms the findings of other authors who categorized processing of fish as female business dominated by economically active ages (Abolagba and Odiko, 2005; Lawal and Idega, 2004). Comparism between the study areas using chi-square test showed that there was a significant difference (P< 0.05). Smoking (100%) as shown in plate 1, was the most practiced curing method in study areas due to cost occassioned by the fact that materials needed are most readily available as well as the increased consumers’ preference of cured smoked fish within the localities. This is in line with the findings of Davies et al., (2009). Majority Abolagba and Nuntah 105 Table 1.

Smoking fish on cut-out half drum smoking kiln. of the respondents (49.9 %.) were able to process at least two baskets of smoked fish per day (Table 2). However, study revealed that during the peak fishing period when catches were abundant and with more than one smoking kiln, greater quantity of smoked fish per basket per day was processed compared to the off peak fishing period when catches were limited and with single smoking kiln. This agrees with the findings of Eyo (1997). Quantity of smoked fish sold per week is dependent on processor’s ability and fresh fish availability. After processing, cured fishes are stored in baskets, jute bags and plastic drums for protection and preservation as shown in plate 2. However during storage, some losses are incured due to insect infestation, rodent attack, mould attack, breakage due to packing, etc. (Table 3). These losses result in the physical disintegration of the stored smoked fish leading to economic loss on the curer. However, proper sealing up of storage areas; use of domestic cats as predators to control rodents and the application of anti-coagulant rodenticides in accordance with manufacturers’ instruction would limit losses incured during storage of cured fish. This is in line, with the findings of Eyo (2001). In the study areas, packaging materials for cured fish were mostly jute bags and paper bags (Plates 3 – 5) and these were confirmed satisfactory to customers due to the qualities of being appealing, convenient to handle, preserves fish quality and reusability (Table 4). This agreed with the assertion of Essuman (1992). However, factors causing difficulty in packaging as observed in the study areas, includes the physical nature of smoked fish whether processed whole or in chunks, its shape and size, which most often results in fish fragmentation. This is in agreement with Sefa-dedeh (1995). Storage of packaged cured fish was mostly done on top smoke house and in the kitchen where appropriate storage temperature is obtainable, as presented on table 5. Study areas are characterized by occasional market days which are known major outlets for sales of smoked fish within the states (Table 6) with road transportation being the major means of distribution of cured fish, using wheel barrows, vehicles, trucks etc as shown in plates 6 – 8.

Price fixation per sales unit depends on bargaining/ negotiating powers between the processors/marketers and customers. Problems encountered in sales as shown in table 7, include low pricing, consumer preference and loss during transportation, which confirmed the findings of Lale and Adu-Nyako (1991). Analysis of income satisfaction from processing and sales of cured fish showed that majority of respondents (73%) were satisfied with income derived from the business, while 27% of the respondents were not satisfied due to high cost of transportation, processing and labour. This is in agreement with the findings of Gaya et al., (2006). Majority of the respondents (87%) in the study areas were able to meet the need of their customers due to the location of study areas as it is surrounded by coastal fishermen who bring their catches onshore for the processors, making fish readily available. However, 16% of the respondents were unable to meet their customers’ needs due to inadequate fund, lack of processing facilities & means of transportation. CONCLUSION The result of this study revealed that smoking method is the most practiced processing method, as it was an effective and economical technique of fish curing in the study areas due to availability of raw materials, increased shelf life stability of the products and the impartation of pleasant taste which is most preferred by consumers Abolagba and Nuntah 111 Plate 11.

Post processing and handling methods of fish such as the packaging techniques, storage conditions and marketing techniques improves the storage life of cured fish. RECOMMENDATION Arising from findings in this study, the following recommendations are hereby made: • Government should engage in the rehabilitation of the access roads leading to the processing communities, so as to improve transportation system, reduce transportation cost and losses due to delays and fragmentation. • Over loading of the transportation vehicles should be discouraged through sensitization programs to limit economic losses due to fragmentation on curers. • • The Federal Department of Fisheries should provide adequate extension personnel to educate the processors/marketers on effective practices and 112 Int.
