Lobster Fisherman
Lobsters are widely fished around the world for their meat. They are often hard to catch in large numbers, but their large size can make them a profitable catch. Although the majority of the targeted species are tropical, the majority of the global catch is in temperate waters. Methods Several methods are used to catch lobsters, with the method depending largely on the species being targeted Lobster pots The large ''Homarus'' lobsters are caught almost exclusively with lobster pots (also called "lobster traps"). These are large rigid objects which the lobster enters voluntarily, often to reach bait, and which it then cannot escape. Traps are also used in some spiny lobster fisheries, such as the fishery for the California spiny lobster, ''Panulirus interruptus'', in the eastern Pacific Ocean. Lobster traps can either be wire or wooden, today fishermen are straying from the wooden traps as they can be heavier than the wire. Traditionally, a lobster trap has two compartments. ...

Closed Season
A hunting season is the designated time in which certain game animals can be killed in certain designated areas. In the United States, each state determines and sets its own specific dates to hunt the certain game animal, such as California, in which they designate certain zones, in which each have their own separate dates in order to legally hunt. In the United States, each state has primary responsibility and authority over the hunting of wildlife that resides within state boundaries. State wildlife agencies that sell hunting licenses are the best source of information regarding hunting seasons, areas open/closed to hunting, etc. Hunting of migratory birds such as ducks and geese A goose ( : geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera '' Anser'' (the grey geese and white geese) and ''Branta'' (the black geese).

Minimum Landing Size
The minimum landing size (MLS) is the smallest fish measurement at which it is legal to keep or sell a fish. The MLS depends on the species of fish. Sizes also vary around the world, as they are legal definitions which are defined by the local regulatory authority. Commercial trawl and seine fisheries can control the size of their catch by adjusting the mesh size of their nets. Effect of selection on fish sizes The idea behind this limitation is that only the older, mature fish get taken, leaving juveniles behind to continue breeding and propagating their species. There is some criticism of this legal requirement, however, as it applies selection pressure to the fish: as the larger fish get taken, the genes for larger size are reduced or removed from the gene pool, while fish that mature at a smaller size continue breeding. The average size of fish shrinks over time. This has led to a collapse in the amount of fish being caught in some fisheries. Aboriginal Australians around Mo ...

Recruitment (biology)
When discussing population dynamics, behavioral ecology, and cell biology, recruitment is several different biological processes. In population dynamics, recruitment is the process by which new individuals are added to a population, whether by birth and maturation or by immigration. When discussing behavioral ecology and animal communication, recruitment is communication that is intended to add members of a group to specific tasks. Finally, when discussing cell biology, recruitment is the process by which cells are selected for certain tasks. Recruitment in population dynamics Definition and importance In population dynamics and community ecology, recruitment is the process by which individuals are added to a population. Successful recruitment is contingent on an individual surviving and integrating within the population; in some studies, individuals are only considered to have been recruited into a population once they've reached a certain size or life stage. Recruitment can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include: growth overfishing, recruitment overfishing, ecosystem overfishing. The ability of a fishery to recover from overfishing depends on whether its overall carrying capacity and the variety of ecological conditions are suitable for t ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Scyllarides
''Scyllarides'' is a genus of slipper lobsters. Characteristics ''Scyllarides'' is placed in the subfamily Arctidinae, which is differentiated from other subfamilies by the presence of multiarticulated exopods on all three maxillipeds, and a three-segmented palp on the mandible. The only other genus in the subfamily, '' Arctides'', is distinguished by having a more highly sculptured carapace, with an extra spine behind each eye, and a transverse groove on the first segment of the abdomen. Taxonomic history In 1849, Wilhem de Haan divided the genus '' Scyllarus'' into two genera, ''Scyllarus'' and ''Arctus'', but made the error of including the type species of ''Scyllarus'' in the genus ''Arctus''. This was first recognised by the ichthyologist Theodore Gill in 1898, who synonymised ''Arctus'' with ''Scyllarus'', and erected a new genus ''Scyllarides'' to hold the species that De Haan had placed in ''Scyllarus''. Species ''Scyllarides'' comprises the following extant specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
