Loch Sunart To The Sound Of Jura Marine Protected Area
Loch Sunart to the Sound of Jura Marine Protected Area is a Marine Protected Area (MPA) off the west coast of Scotland. The MPA, which covers , includes the waters of Loch Sunart, the Sound of Mull, the Firth of Lorne and the Sound of Jura. It has been designated to protect the population of common skate and the area's quaternary geological features. The MPA is designated a Category IV protected area by the International Union for Conservation of Nature. Fishing activities are controlled within the MPA, and no suction dredging, mechanical dredging, beam trawling, demersal trawling or longline fishing Longline fishing, or longlining, is a commercial fishing angling technique that uses a long ''main line'' with baited hooks attached at intervals via short branch lines called ''snoods'' or ''gangions''.

Lochaber
Lochaber ( ; gd, Loch Abar) is a name applied to a part of the Scottish Highlands. Historically, it was a provincial lordship consisting of the parishes of Kilmallie and Kilmonivaig, as they were before being reduced in extent by the creation of ''Quoad Sacra'' parishes in the 19th century. Lochaber once extended from the Northern shore of Loch Leven, a district called Nether Lochaber, to beyond Spean Bridge and Roybridge, which area is known as Brae Lochaber or ''Braigh Loch Abar'' in Gaelic. Lochaber is now also used to refer to a much wider area, one of the 16 ward management areas of the Highland Council of Scotland and one of eight former local government districts of the two-tier Highland region. The main town of Lochaber is Fort William. According to legend, a glaistig, a ghostly woman-goat hybrid, once lived in the area. Name William Watson outlined two schools of thought on this topic. He favoured the idea that ''Abar'' came from the Pictish and Welsh for "river m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary Geology
Quaternary geology is the branch of geology that study developments from 2.6 million years ago onwards. In particular, Quaternary geology study the process and deposits that developed during the Quaternary, a period characterized by glacial-interglacial cycles. Quaternary geology has developed over time from being originally a branch of historical geology to becoming a science on its own. Quaternary geochronology Quaternary geological investigations that require the dating of rocks or sediments require a complementary array of methods to determine that age. Although radiometric dating has rapidly gained importance for Quaternary dating there has historically been a reliance on chemical/biological traces, geomorphic, and relative dating (also known as correlative dating). Since Quaternary geology involves studying changes on the earth surface up to the present, Quaternary geologists benefit from the preservation of time-dependent chemical or biological processes. These methods includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longline Fishing
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long ''main line'' with baited hooks attached at intervals via short branch lines called ''snoods'' or ''gangions''.Method and Apparatus for Long Line and Recreational Bait Fishing Patent application 20080202013. 28 August 2008. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the . This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can l ...

Bottom Trawling
Bottom trawling is trawling (towing a trawl, which is a fishing net) along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone. Bottom trawling can be contrasted with midwater trawling (also known as pelagic trawling), where a net is towed higher in the water column. Midwater trawling catches pelagic fish such as anchovies and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic species such as cod, squid, shrimp, and rockfish. Trawling is done by a trawler, which can be a small open boat with only or a large factory trawler with . Bottom trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling). Global catch from bottom trawling has been estimated at over 30 million tonnes ...

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts: it can disturb marine sediments, leading to both short- and long-term water pollution, destroy important seabed ecosystems, and can release human-sourced toxins captured in the sediment.

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of Scotland
Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site. The various designations overlap considerably with many protected areas being covered by multiple designations with different boundaries. National environmental designations National parks The national parks of Scotland are managed areas of outstanding landscape where some forms of development are restricted to preserve the lan ...

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the enabling laws of each country or the regulations of the international organizations involved. Generally speaking though, protected areas are understood to be those in which human presence or at least the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas, the boundaries of which will include some area of ocean, and transboundary protected areas that overlap multiple countries which remove the borders inside the area for conservation and economic purposes. There are over 161,000 protected areas in the world (as of October 2010) with more added daily, representing between 10 and 15 percent of the world's land surface area. As of 20 ...

Common Skate
The common skate (''Dipturus batis''), also known as the blue skate, is the largest skate in the world, attaining a length of up to .Griffiths AM, Sims DW, Cotterell SJ, El Nagar A, Ellis JR, Lynghammar A, McHugh M, Neat FC, Pade NG, Queiroz N, et al. 2010. Molecular markers reveal spatially-segregated cryptic species in a critically endangered fish, the common skate Dipturus batis. Proceedings of the Royal Society of London B 277: 1497–1503. Historically, it was one of the most abundant skates in the northeast Atlantic Ocean and the Mediterranean Sea. Despite its name, today it appears to be absent from much of this range. Where previously abundant, fisheries directly targeted this skate and elsewhere it is caught incidentally as bycatch. The species was uplisted to critically endangered on the IUCN Red List in 2006 and it is protected within the EU.ICES (11 October 2015.3.12 Common skate (Dipturus batis-complex (blue skate (Dipturus batis) and flapper skate (Dipturus cf. in ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Sound Of Jura
The Sound of Jura () is a strait in Argyll and Bute, Scotland. It is one of the several Sounds of Scotland. It is to the east of the island of Jura and to the west of Knapdale, part of a peninsula of the Scottish mainland. The Crinan Canal's west exit is also in the Sound of Jura. Lochs that lead to the sound include Loch Sween, and Loch Caolisport (Loch Killisport). The north end is particularly treacherous, being filled with skerries, small islands, strong tidal currents and whirlpools. The Gulf of Corryvreckan, which contains a notorious whirlpool, the world's third largest, leads from the north of the sound. The south end, in contrast, is much wider and more open; most of the small islands and reefs are close into shore. The ferries to Colonsay and Islay from the mainland skirt the southern end of the sound. Most of Jura's small population lives on the east coast, overlooking the sound. Intermittently between 1946 and 1949, George Orwell lived in Barnhill, a farmhouse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
