Rome. 90 pp. ABSTRACT The FAO/SEAFDEC Workshop on Principles of Improved Fish Passage at Cross-river Obstacles, with Relevance to Southeast Asia was held in Khon Kaen, Thailand, in March 2013. In this workshop participated representatives from agencies responsible for fisheries and/or construction/operation of cross-river obstacles from Cambodia, Indonesia, the Lao People’s Democratic Republic, Malaysia, Myanmar, the Philippines, Thailand and Viet Nam, as well as the SEAFDEC Secretary-General and officers of the SEAFDEC Secretariat and Training Department, and representatives from the Mekong River Commission (MRC). Country reports on fish passage issues in the participating countries were presented by the participants. Knowledge on fish passage from both the biological and the engineering perspectives, including basic aspect on fish biology and behaviour relevant to fish migration, different types of fish passage facilities, ecological and hydrological requirements for enhancing the effectiveness of fish passages, as well as the monitoring, evaluation and maintenance of fish passages, was presented. Although the known facts are mainly derived from studies in North America and Europe, basic aspects can serve as “food for thought” also in other regions, including Southeast Asia. Information provided and designs presented should, however, under no circumstances just be copied but have to be adapted to local conditions (taking into due consideration the species present) while respecting the important basic design criteria which are valid for all passes of the same type at all locations, whether in Europe, North America or Asia. Importantly, this workshop must not be seen as an encouragement to construct new dams because the principles of the design and construction of fish passage facilities are known. v CONTENTS Page I.

The development of fish growth model uses polynomial growth function. Profit maximization process uses the first derivative of profit equation to culture time equal to zero. This research develop the equations to estimate the culture time to reach the size target of cultured fish. This research model can be applied in the giant gouramy culture. The giant gouramy culture can produce the maximum profit at 324 days with profit of IDR. 7.847.700 per culture cycle. To achieve size target of 500 g per fish, it needs 135 days of culture time.

The Use GIS and Remote Sensing in the Assessment of Magat Watershed in the Philippines A thesis presented in partial fulfilment of the requirements for the degree of Master of Environmental Management Massey University, Turitea Campus, Palmerston North, New Zealand Emerson Tattao 2010 Abstract The Philippine watersheds are continually being degraded— thus threatening the supply of water in the country. The government has recognised the need for effective monitoring and management to avert the declining condition of these watersheds. This study explores the applications of remote sensing and Geographical Information Systems (GIS), in the collection of information and analysis of data, in order to support the development of effective critical watershed management strategies. Remote sensing was used to identify and classify the land cover in the study area. Both supervised and unsupervised methods were employed to establish the most appropriate technique in watershed land cover classification. GIS technology was utilised for the analysis of the land cover data and soil erosion modelling. The watershed boundary was delineated from a digital elevation model, using the hydrological tools in GIS. The watershed classification revealed a high percentage of grassland and increasing agricultural land use, in the study area. The soil erosion modelling showed an extremely high erosion risk in the bare lands and a high erosion risk in the agriculture areas.
