Blueharvest cisco9/3/2023 ![]() ![]() Older dams need to be altered to provide similar benefits, the report adds. It recommends that new dams be located where they have the least impact on river ecosystems and that fish-friendly designs that are managed to allow fish migration and delivery of seasonal flows. Such an approach needs to take into account a wide range of factors, including reducing pollution and destructive fishing practices, maintaining river flows and restoring damaged habitats and protecting wetlands and other feeding and fish spawning grounds. The report urges States to adopt an ‘ecosystem approach’ to managing inland fisheries because of the multiple threats to their health and productivity. ![]() Meanwhile, unofficial estimates put the global inland catch at close to 30 million tonnes, comparable to official marine catches, and employment at 60 million people – 13 million more than in equivalent marine fisheries,” he added. “Why? Because an estimated 100 million people in Africa alone get important levels of daily protein from these inland sources alongside essential vitamins and minerals. While marine fisheries are under increasing scrutiny, those based on river and lake systems rarely engage the international community – an oversight of potentially profound implications,” said Achim Steiner, UNEP’s Executive Director. ![]() “This fascinating report has brought to the fore the often neglected subject of inland fisheries. Nutrients and organic matter from fish eggs, carcasses and excretion support the production of algae, insect larvae and other fish species in rivers and lakes, helping to link ecosystems.ĭeclining fish populations can have a serious knock-on effect for other organisms, the report says, giving the example of the widespread deaths of the cisco fish in Lake Mendota in the United States which led to changes in the plankton composition of the lake, decreased the level of nutrients in the water column and caused a decline in the biomass of algae. It stresses that aside from the nutritional benefits, fish also play a key role in the functioning of aquatic ecosystems and cites the consumption of plankton, plants, insects, and other fish as critical to the stability and resilience of river and lake habitats. Urbanization, road-building, pollution, including wastewater discharge into inland fisheries and climate change are some of the other threats to the fresh water fish, says the report, which was launched at the 10th conference of the parties to the UN Convention on Biological Diversity ( CBD) under way in the Japanese city of Nagoya. Maybe this could be an interesting question for some people, especially for the qnap engineers NOT updating the firmware to improve integration in an all-mac environment.The need to conserve and properly manage inland fisheries is often neglected despite the crucial role they play in balancing aquatic ecosystems and as sources of food and livelihoods to millions of people across the world, a new report released today by the United Nations Environment Programme ( UNEP) says.Īccording to the new publication, rapid environmental changes constitute a challenge to the viability of future fish stocks despite more than 40 years of steady production globally.Ĭhanges in seasonal flooding patterns and loss of habitat, unsustainable farming practices and excessive use of water from lakes and rivers are some of the threats to inland fish, according to the report, prepared jointly by UNEP and the World Fish Centre and entitled Blue Harvest: Inland Fisheries as an Ecosystem Service. What device (in this budget class) could an independent mac-experienced IT-manager suggest? But after reading this thread and other threads (all about the same AFP sharing problem), i'm seriously doubting if this is a good device in an all-mac lan.Įven this is a Qnap forum - they can just learn from it (and fasten up their AFP support) -, i can tell that competitors are Synology RS409 or 2nd-hand Xserve with intel.Īll three machines are about the same price, based on 2 Tb of total capacity (the Xserve being 3-4 years old, but still faster than any of the other brand new devices). Perhaps we need to raise it again in a new thread?įor all of you people posting comments on this thread it is too late: you have bought a qnap nas server.įor me, i am seriously looking for a rack-mountable, reliable and fast networked file server (and perhaps webserver, mediaserver, mailserver and even 'experiment' server) most likely in RAID5, and one of the possible devices was the qnap TS419U.
