Classic strategies (like precautionary approach of the International Council for the Exploration of the Sea, ICES) were compared to strategies defined from a viability control model for the Peruvian anchovy, which provides the biomass levels B which can be sustainable managed (viability kernel) and its related sustainable yields. Five management strategies (E1--E5) were considered to define the total allowable catch Y* for the Peruvian anchovy (Engraulis ringens): E1) social quota (Y* = Ymin), E2) ICES precautionary quota, E3) maximum viable quota Y*=Ymax(B), E4) maximum precautionary viable quota and, E5) half precautionary viable quota. We used five indicators for sustainability, related to the risk of collapse and the mean and variability of yields and biomasses. Two scenarios for initial biomasses were considered (healthy stock and postcollapse recovering stock). The analyses were done with Monte Carlo simulations, with 10 000 simulations per scenario and strategy. Uncertainty was incorporated in the quota implementation, simulating the variability of discards and illegal catches. The effect of the enviroment during 1963-- 1984 was considered by changing the stock-recruitment parameters during El Niño events. We found that the half precautionary viable quota (E5) could avoid the anchoveta fishery collapse in 1972--1973, allowing yields greater than the social quota. Also, the ICES precautionary strategy (E2) did not ensure the sustainability of the stock during El Niño events. We determine that a one year fishery moratorium after the fishery collapse would have been necessary to return to the viability kernel, allowing a sustainable management thereafter. We conclude that the viability kernel and viable yields are useful tools for designing management strategies which ensure the sustainability of natural resources. No poster available.

In the Central Delta of the Niger River in Mali, fishers are massively involved in rice farming as secondary activity and many of them are equipped with motorized canoes to carry out seasonal migrations. Nevertheless, they have difficulties to use such capacities to cope with the interannual variations of hydrology. Because the Delta area has long been occupied and has reached saturation and because of the strong seasonality affecting the floodplain ecosystem, the fishers undergo heavy constraints when handling their activities. Thus, the diversity of the observed traditional livelihoods strategies among floodplain fishers communities is the result of fine tunings in exploitation strategies and in social sharing of the natural resources, but it by no means constitutes a range of flexible options. Hence, fishers households have actually few real degrees of freedom to manage their trajectories to face the environmental stresses, namely the weakening of the seasonal flood. Therefore, distant migration to other aquatic ecosystems (such as estuaries and reservoirs) is the most frequent answer adopted by the floodplain fishers under hydro-climatic changes, in spite of the associated risks. This exile maybe accentuated in the next years with the creation of new dams and the extension of irrigation in the upstream parts of the Basin of Niger which will reduce their present natural resources.

As an individual, anybody who is exploiting the common resource will not think of any conservation because the benefits in the short term are much better, creating a conflict of interests between the rational individual and what seems rational for the community. eg. Coastal trawl fishery in India. In this paper the regulatory framework on inland water fishing in India is discussed which includes the collection of indigenous species for ornamental fish trade. The need for limiting the harvesting of fish and thus end open access in fisheries became widely recognized. In India, the National and All State Governments are in the process of amending the Legal Frame Work in tune with the Code of Conduct for Responsible Fishing of the FAO. Some of the State Governments have already achieved this goal. India is set to have Green Certification for each and every species of fresh water ornamental fishes and registration of native species under the Geographical Indications of Goods (Registration and Protection) Act, 1999 for effective international trade and tracking of the source of the products, its characteristics including IUCN status and GI. Indian producers and exporters are also moving towards market orientation for better markets and acceptance of their products. At present India has no legislation on the importation or introduction of aquatic organisms nor is there a proper quarantine procedure in place for imported fishes. However, the country is now on its way to have an efficient regulation and management policy for exotic species introduction and quarantine procedure for both imported and exported ornamental fishes. The paper deals in details on the various property rights issues encountered while implementing various Acts and Regulations. No poster available.
