Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom. History During the 17th century, the British developed the Dogge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genypterus Capensis
''Genypterus capensis'', commonly known as kingklip, is a species of cusk eel occurring along the Southern African coast from Walvis Bay in Namibia to Algoa Bay in South Africa. It is closely related to '' Genypterus blacodes'' from New Zealand. The species grows to a maximum length of 180 cm, a weight of 15.0 kg. It is one of the most popular fish items on South African menus. Despite appearances, it is not closely related to the eels of the order Anguilliformes. Kingklip occur at depths from 50–500 m, but usually in the range 250–350 m. They are bottom-dwelling and inhabit rocky localities on the shelf and upper continental slope. Juveniles are more often found in shallow waters. They feed on dragonets, mantis shrimps, hake, squid, and various fish species. Spawning usually takes place from August to October. The species is oviparous, with oval pelagic eggs floating in a gelatinous mass. Their dorsal soft rays number 150, while the anal soft rays number 110. The he ...

Marine Sediment
Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor. These particles have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea. Additional deposits come from marine organisms and chemical precipitation in seawater, as well as from underwater volcanoes and meteorite debris. Except within a few kilometres of a mid-ocean ridge, where the volcanic rock is still relatively young, most parts of the seafloor are covered in sediment. This material comes from several different sources and is highly variable in composition. Seafloor sediment can range in thickness from a few millimetres to several tens of kilometres. Near the surface seafloor sediment remains unconsolidated, but at depths of hundreds to thousands of metres the sediment becomes lithified (turned to rock). Rates of sediment ...

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 ...

Black Economic Empowerment
Black Economic Empowerment (BEE) is a policy of the South African government which aims to facilitate broader participation in the economy by black people. A form of affirmative action, it is intended especially to redress the inequalities created by apartheid. The policy provides incentives – especially preferential treatment in government procurement processes – to businesses which contribute to black economic empowerment according to several measurable criteria, including through partial or majority black ownership, hiring black employees, and contracting with black-owned suppliers. The preferential procurement aspect of BEE has been viewed as paradigmatic of a sustainable procurement approach, whereby government procurement is used to advance social policy objectives. So-called "BEE deals" – transactions aiming to increase black ownership of large businesses – have been conducted on a large scale, with BEE transactions concluded between 1994 and 2005 valued at between ...

Transition To Democracy
Democratization, or democratisation, is the transition to a more democratic political regime, including substantive political changes moving in a democratic direction. It may be a hybrid regime in transition from an authoritarian regime to a full democracy, a transition from an authoritarian political system to a semi-democracy or transition from a semi-authoritarian political system to a democratic political system. The outcome may be consolidated (as it was for example in the United Kingdom) or democratization may face frequent reversals (as happened in Chile). Different patterns of democratization are often used to explain other political phenomena, such as whether a country goes to a war or whether its economy grows. Whether and to what extent democratization occurs has been attributed to various factors, including economic development, historical legacies, civil society, and international processes. Some accounts of democratization emphasize how elites drove democratization ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Stewardship Council
The Marine Stewardship Council (MSC) is a non-profit organization which aims to set standards for sustainable fishing. Fisheries that wish to demonstrate they are well-managed and sustainable compared to the MSC's standards are assessed by a team of Conformity Assessment Bodies (CABs). The mission of the MSC is to use its ecolabel, for which the MSC receives royalties for licensing it to products, and fishery certification program to recognise and reward sustainable fishing practices. The MSC has faced criticism in the past, mainly centering on its close ties to the fishing industry and conflict of interest stemming from royalties received by the industry for its certification label. Contribution to changes in the oceans When buyers choose MSC-certified fish, well-managed fisheries are rewarded for sustainable practices. In turn, the growing market for certified sustainable seafood generates a powerful incentive for other fisheries to demonstrate they are fishing sustainabl ...

Lophius Vomerinus
Members of the genus ''Lophius'', also sometimes called monkfish, fishing-frogs, frog-fish, and sea-devils, are various species of lophiid anglerfishes found in the Atlantic and Indian Oceans. ''Lophius'' is known as the "monk" or "monkfish" to the North Sea and North Atlantic fishermen, a name which also belongs to ''Squatina squatina'', the angelshark, a type of shark. The North European species is ''Lophius piscatorius'', and the Mediterranean species is ''Lophius budegassa''. Species The seven recognized extant species in this genus are: Fossils * †''Lophius brachysomus'' Agassiz, 1835 (Monte Bolca, or Eocene anglerfish) Description The head is large, broad, flat, and depressed, with the remainder of the body appearing merely like an appendage. The wide mouth extends all around the anterior circumference of the head, and both jaws are armed with bands of long, pointed teeth, which are inclined inwards, and can be temporarily depressed to offer no impediment to an o ...

South African National Biodiversity Institute
The South African National Biodiversity Institute (SANBI) is an organisation established in 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004, under the South African Department of Environmental Affairs (later named Department of Environment, Forestry and Fisheries), tasked with research and dissemination of information on biodiversity, and legally mandated to contribute to the management of the country’s biodiversity resources. History SANBI was established on 1 September 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004. Previously, in 1989, the autonomous statutory National Botanical Institute (NBI) had been formed from the National Botanic Gardens and the Botanical Research Institute, which had been founded in the early 20th century to study and conserve the South African flora. The mandate of the National Botanical Institute was expanded by the act to include the full diversity of the South Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demersal
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone. Being just above the ocean floor, the demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which begins between depths of roughly and extends to the ocean depths, where no light penetrates. Fish The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (''Gadus morhua'') is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (''Clupea harengus'') is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zone: those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Environmental Observation Network
The South African Environmental Observation Network (SAEON) is a science network of people, organisations and, most importantly observation platforms, that perform Long-Term Ecological Research (LTER) in South Africa and its surrounding oceans. The SAEON is of global importance as an innovative approach in ecology to understand environmental change and to determine the impact of anthropogenic forces at multiple scales but it is a remarkably complex challenge to statistically discern between ubiquitous natural variability and exogenous forcing.Andelman SJ & Willig MR, 2004. "Networks by Design: A Revolution in Ecology". ''Science'' 305(5690):1565-1567 The SAEON constitutes a national government response to the World Summit on Sustainable Development (Earth Summit 2002) and is a component of the GEO (Group on Earth Observations). The SAEON has become the leader in environmental science and observation in South Africa, but has been criticised for taking a long time to establish, a ...
