  Citation × Citation Citation Abstract Copy Title: The Current State of the Clam, Galatea paradoxa, Fishery at the Lower Volta River, Ghana Author: Agbeko, N.A., Obirikorang, K.A., Adjei-Boateng, D., Amisah, S., Agbo, N.W. The clam, Galatea paradoxa has for decades been an important source of protein to the riparian communities of the lower Volta River and provides employment to about 2000 people, especially women. The fishing grounds have dwindled from 100 km from the pre-dam era to a narrow stretch of 10 km as a result of the development of sand bars at the estuary. This study was conducted to ascertain the socio-economic importance of the clam fishery to the people of the lower Volta, Ghana. The research found out that there were 251 fishing canoes and 503 fishers engaged in the clam fishery. The average daily catch per fishing canoe was 130 kg of clams, with an annual harvest of 7700 tonnes worth 4,620,408 Ghana Cedis. Commercial extinction of G. paradoxa is imminent in the lower Volta as a result of habitat alteration and overfishing. There is the need to put in place a sustainable harvesting measure that will target medium to large size clams against the current situation where the catch is dominated by smaller clams. It is recommended that a minimum landing size of 50 mm should be imposed. This should be done in consultation with the chiefs and traditional authorities in the communities which have managed the fishery to date. The marketing of clams below the 50 mm shell length limit should be abolished and enforced by the traditional authorities. Secondly, the farming of smaller clams, which is a traditional activity in the estuary, should be encouraged so that fishers who harvest undersize clams can seed them onto their culture plots.

  Citation × Citation Citation Abstract Copy Title: The Structure of Wholesale and Retail Marketing Catfish (Clarias Gariepinus Burchell,1822) In Southwest Nigeria Author: Adewale, Jacob Gbemiga, Ipinmoroti, Mabel Omowumi, Olaniyi, Zaccheaus Oluwafemi, Ayanboye, Abolupe Oluyemi The structure of wholesale and retail marketing catfish (Clarias gariepinus) were analysed in order to assess the degree of competition and understand the organization of the farm raised catfish (Clarias gariepinus) market in southwestern Nigeria, a major aquaculture fish producing area in Nigeria. The market was evaluated by considering the degree of market concentration, conditions of entry and magnitude of product differentiation. Sixty –four (64) catfish wholesalers (CW) and one hundred and thirty-seven (137) retailers (CR) were purposely selected from the market. Two sets of structured questionnaires were administered on wholesalers and retailers. The data were analyzed using descriptive statistics with the used of frequency distribution, percentages and Lorenz curve with the accompany Gini coefficient. Analysis of the market structure reveals that fewer numbers of wholesalers were able to influence price to their own advantage. The market is characterized by existence of barrier to entry for potential entrepreneurs due to inadequate investment cost and the presence of fish seller's association. Both markets are oligopolistic . The market has distribution, with Gini coefficient of 0.66 and 0.60 at wholesale and retail levels respectively. Confirming that wholesale is more concentrated than retail market. Some recommendations for the raised Clarias gariepinus business include increased access to credit for traders to increase entry and Government should provide a good market place for the sellers with good infrastructures.
