New approaches for the improvement of inland capture fishery statistics in the Mekong Basin

Descripción

Inland capture fisheries provide a valuable contribution to food security in the Mekong Basin. However, official tiol estimates of this contribution have consistently been lower than estimates derived from more focused and localized fishery surveys. Thus, inland capture fisheries are undervalued by decision makers and development agencies. The poor state of knowledge on inland fisheries arises from the diverse ture of inland fisheries, that fisheries are often small-scale and dispersed over la rge areas, that inland fishers have idequate political power, the misconception that inland fisheries are not valuable, the local consumption or bartering of inland fisheries harvest, and the excessive power of certain stakeholders that do not want the actual value known. Development activities may then ippropriately focus on other sectors at the expense of rural communities that depend on inland fisheries. Accurate information on the contribution of inland fisheries is essential for responsible development. Key uses of accurate information identified at the Expert Consultation were: i) to determine the status and trends of the fishery and the environment, ii) to assess correctly the value of inland fisheries, iii) to allocate appropriate resources to the inland fishery sector, and iv) to fulfill intertiol obligations. In general, information collection in the Mekong is based on figures collected from government fishery officers assessing catch and effort data. These methods are best s uited to formal, large-scale fisheries, but are ippropriate for many of the small- scale, informal fisheries of the Mekong Basin. Altertive approaches are being developed and evaluated that include individual fishers, household and communities, and proxy measures of fishery yield. Besides the traditiol catch and effort surveys, approaches to improve information on inland fisheries were identified to include agriculture surveys, consumption studies (including household surveys), market surveys, g eo-referenced information, habitat classification and measurement, and establishment of co-magement or fishery user groups. In the lower Mekong Basin, the primary information need was yield. The informal and formal fishery sectors must be treated differently to obtain accurate information on both. The results from focused studies on particular habits or fisheries can be extrapolated to provide information on a wider area within the basin. There is a strong seasol component to the fisheries that must be considered and the capacity and status of local fishery officers must be increased in order to facilitate accurate reporting. Useful information already exists in project reports, with NGOs and IGOs, and in government offices that should be alyzed, and stakeholders in inland fisheries should form partnerships with other users of inland water resources.
