Effort de pêche et production exploitée dans les petites retenues du Nord de la Côte d'Ivoire

The fishermen density by dam, from 4 to 17 fishermen.km2, is well above FAO norms (2 fishermemkm2). The catch and the effort are highly variable from dam to dam. The fish production varies from 70 to 224 kg.ha-'.y-', which is in the same order of magnitude as the values registered in other small dams of the West African region. Yet, catch values are under FAO potential catches given for similar water bodies (between 100 and 750 kg-ha-y),indicating that there is a possibility of fish production increase. Total estimated catches in the small dams in the north of the Ivory Coast represent from 16 to 46 % of total freshwater catches. Catches include economically important fishes (Oreochromis niloticus, Heterotis niloticus, Chrysichthys spp, etc.) and marketing values indicate that the fishing activity is an important source o currency for the villages.

El ensayo arranca con la revisión de las características socioeconómicas y ecológicas de la región y el análisis de las actividades del proyecto y de sus impactos potenciales. En base a una atenta ponderación de los mismos y de sus posible mitigaciones, las conclusiones del ensayo descartan el relevante aumento de la producción pesquera y apuntan hacia la promoción del valor agregado vinculado con actividades como la comercialización, el procesamiento de los productos ícticos, los servicios a la pesca (reparación de redes y embarcaciones, compra compartida de las artes de pesca, etc.) y el turismo a pequeña escala.

Economies of Scale and Concentration in the Greek and the Norwegian Aquaculture Industry. An empirical Study.

by Konstantinos Vergos

The purpose of this study is to investigate whether there are economies of scale in the Greek and Norwegian fish farming industry, and to examine the structure of the sector

Keywords: Fisheries, industry structure, regulation, Government Expenditures and Health, Market Structure

Cobb-Douglas production function, while we examine the structure of the fish-farming by computing the HHI
indicator over different years. We find that the market concentration level is high in Greece in both relative, to
Norway, and in absolute terms. From the other part, Norway, the leader of the fish farming of Atlantic salmon
and Rainbow trout globally, suffers from economies of scale in the examined period. Given the fact that both
Greek and Norwegian production is targeting large markets in Europe (UK, France, Italy) both the findings in
Greece and Norway may be worrying signals, that large M&A activity may lead to decreasing competition
and increasing returns to scale in the industry, as previously happened in the food retail industry. Given the
important contribution of fish farming to poverty alleviation, food security and social well being, European
regulators should investigate whether it is optimal to exercise policies that enhance technology transfer and
limit further market concentration.
