  Citation × Citation Citation Abstract Copy Title: Capital Utilization and investment Decisions: A Case Study for the Netherlands Author: Buisman, Erik, Bartelings, Heleen In this paper a data envelopment model is presented to evaluate short term investment decisions in the Dutch beam trawl and demersal fleet. We investigated how short run profit drives investment decisions and how a data envelopment analysis can be used to show what the optimal level of capital use is and how investment in variable and fixed inputs can optimize the output of the sector. The degree of capital utilization can be seen as a measure of whether firms should invest or disinvest in their capital assets. Capital utilization also measures to which extent idle and excess capacity is present in a firm. Differences in capital utilization mainly depend on the degree in which a firm can adjust fixed capital in the short run. It therefore should be a key economic parameter to evaluate the performance of a sector. We measured the physical capital utilization for the Dutch beam trawl and demersal fleet for 2005 and decomposed the capacity utilization into technical efficiency, economic capital utilization and optimal capacity idleness. Furthermore we illustrated how the economic capacity measure can be used to predict investment decisions in the fleet. Results show that economic capital utilization inefficiency is on average 13%, which indicates that landings could have been 13% higher then they were if the fleet operated 100% efficiently. About 1% of the capacity utilization inefficiency is caused by idle/excess capacity. This very low percentage indicates that there are few indivisibilities in the input for the Dutch beam trawl and demersal fleet. Based on short term profit maximization it is clear that it is optimal to make as much use of the available capital as possible. The remaining 12% can be attributed to economic capacity inefficiency and technical inefficiency in the fleet. Vessels with a low capital utilization are more likely to disinvest than vessels with a high capital utilization. Vessels with a capital utilization that is higher than unity almost always will choose to invest.

• 3. [Article] Impacts of Vessel Capacity Reduction Programs on Efficiency in Fisheries: the Case of Australia's Multispecies Northern Prawn Fishery

  Citation × Citation Citation Abstract Copy Title: Impacts of Vessel Capacity Reduction Programs on Efficiency in Fisheries: the Case of Australia's Multispecies Northern Prawn Fishery Author: Coglan, Louisa, Punt, Andre E., Dichmont, Catherine M., Pascoe, Sean Capacity reduction programs in the form of buybacks or decommissioning programs have had relatively widespread application in fisheries in the US, Europe and Australia. A common criticism of such programs is that they remove the least efficient vessels first, resulting in an increase in average efficiency of the remaining fleet. The effective fishing power of the fleet, therefore, does not decrease in proportion to the number of vessels removed. Further, reduced crowding may increase efficiency of the remaining vessels. In this paper, the effects of a buyback program on average technical efficiency in Australia’s Northern Prawn Fishery are examined using a multi-output distance function approach with an explicit inefficiency model. The results indicate that average efficiency of the remaining vessels was greater than that of the removed vessels, and that average efficiency of remaining vessels also increased as a result of reduced crowding.

  Citation × Citation Citation Abstract Copy Title: Contribution of Children in Artisanal Fisheries to Households’ Poverty Alleviation in Ondo State, Nigeria Author: Mafimisebi, Taiwo Ejiola, Fasina, Oluwatosin Despite the global clamour for the eradication of child labour in agriculture, children in developing countries continue to be prominent actors in the fisheries sector though their contribution is unrecorded in the national income accounts of many countries. The study examined the involvement of children in artisanal fisheries in Ondo State, Nigeria. Simple random sampling procedure was used to select 90 children aged 9-18 years who were involved in artisanal fishing activities. Descriptive statistics were used to present the data gathered for the study. Pearson Product Moment Correlation and the Chi-Square analysis were used to test the study hypotheses at the 0.05 level of significance. Respondents were mostly males (70%) with mean age of 15 ± 2 years. Fishing experience for two-thirds was over 7 years. Major economic activities engaged in by children were fishing (100.0%) and fish marketing (97.8%). All respondents fished more on rivers, lakes, creeks and canals with friends mostly in the mornings (70.0%) between 4-5am (43.3%). Mean daily catch per caput per day amounted in monetary terms to N317. Income increased significantly with age of children (r = 0.27, p< 0.05). Respondents’ major constraint was lack of capital to purchase nets and boats of their own (97.8%). Sustainable involvement of children in artisanal fisheries can help alleviate poverty as the children remitted their incomes to their parents for food, school fees or other school needs. Children’s capacity for production can be boosted through capacity building and greater access to fishing equipment and capital assets used in fishing. Scholarship programmes should be put in place to encourage children who do well at both school and fishing to further develop the quality of future manpower available for fishing in the coastal areas.
