Integrated analysis of data from MRC Fisheries Monitoring Programmes in the Lower Mekong Basin
Publisher: Mekong River Commission Secretariat
Date: 30-08-2013
DOI: 10.52107/MRC.AJGSD2
Abstract: This report analyses time series of data collected at more than 50 locations on capture fisheries in the Lower Mekong Basin, including dai fishery in Cambodia, lee trap fish in Southern Laos, fish larvae monitoring in Cambodia and Viet Nam and fish abundance and ersity monitoring in the four Member Countries.
Speaking the same language: can the sustainable development goals translate the needs of inland fisheries into irrigation decisions?
Publisher: CSIRO Publishing
Date: 2019
DOI: 10.1071/MF19176
Abstract: Irrigated agriculture and inland fisheries both make important contributions to food security, nutrition, livelihoods and wellbeing. Typically, in modern irrigation systems, these components operate independently. Some practices, commonly associated with water use and intensification of crop production can be in direct conflict with and have adverse effects on fisheries. Food security objectives may be compromised if fish are not considered in the design phases of irrigation systems. The 2030 Agenda for Sustainable Development provides a framework that can serve as a backdrop to help integrate both sectors in policy discussions and optimise their contributions to achieving the Sustainable Development Goals (SDGs). Inland fisheries systems do play an important role in supporting many SDG objectives, but these contributions can sometimes be at odds with irrigated agriculture. Using case studies of two globally important river catchments, namely the Lower Mekong and Murray–Darling basins, we highlight the conflicts and opportunities for improved outcomes between irrigated agriculture and inland fisheries. We explore SDG 2 (Zero Hunger) as a path to advance our irrigation systems as a means to benefit both agriculture and inland fisheries, preserving bio ersity and enhancing the economic, environmental and social benefits they both provide to people.2
Priority knowledge needs for management of migratory fish species in Cambodia
Publisher: Wiley
Date: 17-04-2021
DOI: 10.1111/FME.12483
Abstract: Despite their economic and ecological importance, migratory fishes of the Lower Mekong Basin (LMB) remain understudied, which h ers effective management to sustain valuable fisheries and address serious threats such as habitat degradation, development and overharvest. From a list of potential knowledge needs, a group of fisheries professionals most frequently identified six top priorities for managing migratory fishes in Cambodia: (1) population abundances and trends, (2) life cycles and life history, (3) migration timing and triggers, (4) migration routes and distances, (5) locations of key habitats and spawning areas, and (6) environmental and habitat requirements. These needs are discussed along with nine relevant methodologies for addressing them, including fisheries‐dependent and fisheries‐independent s ling, reproductive techniques and captive studies, otolith and genetic analysis tools, and tagging and imaging techniques. A suggested research framework is also presented to inform adaptive management of migratory fishes. While emphasis is given to Cambodia, the analysis is also applicable to other LMB countries, given that migratory fishes occur throughout the basin and migrate across borders. It is suggested that a robust research and monitoring agenda is required to prioritise knowledge needs and select appropriate methodologies to answer questions vital to inform sustainable migratory fish management in Cambodia.
Atlas of deep pools in the Lower Mekong River and some of its tributaries

Abstract: This atlas enhances knowledge and understanding of the distribution, ecological functioning and conservation of deep pools while synthesizing results from local ecological knowledge-based surveys and geomorphic statistical analysis of the Mekong mainstream.
Diverse migration tactics of fishes within the large tropical Mekong River system
Publisher: Wiley
Date: 02-06-2022
DOI: 10.1111/FME.12566
Abstract: Fish often migrate to feed, reproduce and seek refuge from predators and prevailing environmental conditions. As a result, migration tactics often vary among species based on a ersity of life history needs, although variation within species is increasingly being recognised as important to population resilience. In this study, within‐ and among‐species ersity in life history migratory tactics of six Mekong fish genera was examined using otolith microchemistry to explore diadromous and potamodromous traits. Two species were catadromous and one species was an estuarine resident, while the remaining three species were facultative in their migration strategies, with up to four tactics within a single species. Migrant and resident contingents co‐existed within the same species. Management, conservation and mitigation strategies that maintain connectivity in large tropical rivers, such as effective fishway design, should consider a ersity of migration tactics at the in idual level for improved outcomes.

Measures to safeguard and restore river connectivity
Publisher: Canadian Science Publishing
Date: 22-06-2023
DOI: 10.1139/ER-2023-0019
Abstract: Freshwater connectivity and the associated flow regime are critical components of the health of freshwater ecosystems. When freshwater ecosystems are fragmented, the movements and flows of species, nutrients, sediments, and water are altered, changing the natural dynamics of freshwater ecosystems. The consequences of these changes include declines and loss of freshwater species populations and freshwater ecosystems, and alterations in the delivery of certain ecosystem services, such as fisheries, buffering of flood events, healthy deltas, recreational and cultural values, and others. Measures exist that can maintain and restore connectivity or mitigate against its loss in the face of constructed barriers or other habitat alterations. These measures include system-scale planning for energy and water resources that includes options for limiting loss of freshwater connectivity putting in place protections for keeping critically important freshwater habitats connected mitigating impacts on freshwater ecosystems via barrier design, fish passage, or implementation of environmental flows and restoring freshwaters via barrier removal and reconnection of rivers, wetlands, and floodplains and via active management of groundwater recharge. We present case studies of measures applied in Europe, Asia, Africa, and the Americas and reflect on the next generation of innovation needed to further enhance and advance the implementation of restoration and protection and the mitigation of freshwater connectivity impacts.
