The Philippine crocodile Crocodylus mindorensis is Critically Endangered and its range is restricted to a few localities in human-dominated landscapes. Therefore, the survival of this species in the wild depends strongly on the support of local people. Communication and education are prerequisites for successful in situ conservation.
The Hilsa shad, Tenualosa ilisha popularly known as ‘Hilsa’, is one of the most commercially important fish species in South Asian countries. The species is widely distributed from the Persian Gulf to Bay of Bengal and ascends into estuaries, rivers and brackish-water lagoons of the Indo-Pacific region. Recently, the availability of hilsa has drastically dwindled in aquatic systems across this region, due to anthropogenic pressures, mainly intensive fishing and river obstruction by dams and barrages. Climate change may also be contributing to the declining populations.
The fisheries sector in Cambodia contributes 8%–12% to national GDP and 25% - 30% to agricultural GDP, with an estimated 4.5 million people involved in fishing and associated trades. Fish and other aquatic animals are important food sources, contributing an estimated national average of 60% - 70% of total animal protein intake. Of the 2013 total fish production, 550,000 metric tons were harvested from freshwater habitats, of which rice field fisheries and small-scale family fisheries contributed approximately 20%.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is being implemented in ten communities in the Barotse floodplain in Zambia’s Western Province. The objective of the AAS program is to reduce poverty and improve food security by harnessing the potential, productivity and diversity of aquatic and agricultural systems.
Fish is crucial to food and nutrition security in Solomon Islands, and demand is expected to increase due to a growing population. However, it is projected that current capture fisheries production will not meet this growing demand. Aquaculture has the potential to mitigate the capture fishery shortfall, and the Government of Solomon Islands is prioritizing aquaculture as a solution to meet future food and income needs. Aquaculture in Solomon Islands is still in early development.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is collaborating with partners to develop and implement a foresight-based engagement with diverse stakeholders linked to aquatic agricultural systems. The program’s aim is to understand the implications of current drivers of change for fish agri-food systems, and consequently food and nutrition security, in Africa, Asia and the Pacific.
In this study the authors investigated whether short-term protection from predation improved survival of cultured juvenile sandfish released into a range of seagrass habitats located within potential community sea ranching sites. It also describes the biophysical properties of the habitats and relates these to sandfish growth. The results will assist project managers and community farmers in optimising methods for releases and in selecting suitable sites for sea ranching operations in New Ireland Province (NIP), PNG.
Aquaculture is the fastest-growing food production sector globally, with production projected to double within the next 15–20 years. Future growth of aquaculture is essential to providing sustainable supplies of fish in national, regional and global fish food systems; creating jobs; and maintaining fish at affordable levels for resource-poor consumers. To ensure that the anticipated growth of aquaculture remains both economically and ecologically sustainable, we need to better understand the likely patterns of growth, as well as the opportunities and challenges, that these trends present.
Details are given of the tilapia hatchery systems used in the Philippines i.e., the "hapa" floating hatcheries and the backyard pond hatcheries, and their applications in Indonesia. Experiments are being conducted in Saguling Reservoir, near Bandung, Indonesia using hapa hatcheries, holding broodstock and growout fingerlings in floating cages. This technology is showing great potential for reaching poor farmers who have little land or capital but adequate water and access to irrigation.
The genetic response in growth traits in a selection program for increased harvest weight in a common carp population in Vietnam is reported. A base population (G0) was established from six carp stocks using single pair mating. Selection was based on high breeding values for body weight at harvest, with a corresponding control group selected on average breeding values of the population.
