Tautog
The tautog (''Tautoga onitis''), also known as the blackfish, is a species of wrasse native to the western Atlantic Ocean from Nova Scotia to South Carolina. This species inhabits hard substrate habitats in inshore waters at depths from . It is currently the only known member of its genus. Barlett (1848) wrote, " autaugis a Native American word, and may be found in Roger Williams' ''Key to the Indian Language''." The name is from the Narragansett language, originally ''tautauog'' (pl. of ''taut''). It is also called a "black porgy" (''cf.'' Japanese black porgy), "chub" (''cf.'' the freshwater chub), "oyster-fish" (in North Carolina) or "blackfish" (in New York/New Jersey, New England). Description Tautog are brown and dark olive, with white blotches, and have plump, elongated bodies. They have an average weight of and reach a maximum length and weight of and respectively. Tautog have many adaptations to life in and around rocky areas. They have thick, rubbery lips and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cunner
The cunner (''Tautogolabrus adspersus''), also known as the blue perch, bergall, chogset, choggie, conner or sea perch, is a species of wrasse native to the northwestern Atlantic, where it is found from the Gulf of St. Lawrence and Newfoundland to the Chesapeake Bay. They inhabit inshore waters living near the sea floor at depths from , preferring areas with beds of seaweed, shipwrecks, or wharf pilings. They spend the winter months in a state of torpor underneath rocks. They can also be found in the aquarium trade. Often, cunner is found mixed in with tautogs, living on or near the same structures. Much of the food eaten by those bergall living among blackfish are the leftovers from the blackfishes prey. They can be distinguished from the tautog by their pointed snouts. Cunners are generally smaller, so are usually thrown back by anglers who think they caught a "short" tautog. In past years, they have been important commercial fish, but now are considered pests. They can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tautoga Americana (Massachusetts Bay, June 1860)
The tautoga (pronounced ) is considered the most formal and restrained style of Rotuman dance, usually seen performed in large festivities or ceremonies (called ''kato'aga'', a term summing up all traditional Rotuman ceremonies), or in public opportunities to showcase Rotuman culture. The tautoga style can be seen as comparable to the Tuvaluan fatele or Tongan lakalaka, and the "toga" sound to the word alludes to such an origin. Performers Dance groups in tautoga (called hafa, a loanword referring to the halves of the dance group) can vary in number from 10 people to 100+ people, depending on availability of dancers and the scale of the event. The men and women usually arrange themselves in rows and in a rectangular shape, with men on one side, women on the other like the lakalaka, and also analogous to the Tongan dance, the most attractive and competent dancers stand in the front row centrally (this factor is referred to in Rotuman culture as "mạru") and these attributes decl ...

Wrasse
The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 81 genera, which are divided into 9 subgroups or tribes. They are typically small, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera ''Bodianus'', ''Epibulus'', ''Cirrhilabrus'', ''Oxycheilinus'', and ''Paracheilinus'' hide among the tentacles of the free-living mushroom corals & ''Heliofungia actiniformis''. The word "wrasse" comes from the Cornish word ''wragh'', a lenited form of ''gwragh'', meaning an old woman or hag, via Cornish dialect ''wrath''. It is related to the Welsh ''gwrach'' and Breton ''gwrac'h''. Distribution Most wrasses inhabit the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clam
Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. They live in both freshwater and marine environments; in salt water they prefer to burrow down into the mud and the turbidity of the water required varies with species and location; the greatest diversity of these is in North America. Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; however, razor clams have an elongated parallel-sided shell, suggesting an old-fashioned ...

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 ...

Zostera
''Zostera'' is a small genus of widely distributed seagrasses, commonly called marine eelgrass, or simply seagrass or eelgrass, and also known as seaweed by some fishermen and recreational boaters including yachtsmen. The genus ''Zostera'' contains 15 species. Ecology ''Zostera marina'' is found on sandy substrates or in estuaries, usually submerged or partially floating. Most ''Zostera'' are perennial. They have long, bright green, ribbon-like leaves, the width of which are about . Short stems grow up from extensive, white branching rhizomes. The flowers are enclosed in the sheaths of the leaf bases; the fruits are bladdery and can float. ''Zostera'' beds are important for sediment deposition, substrate stabilization, as substrate for epiphytic algae and micro-invertebrates, and as nursery grounds for many species of economically important fish and shellfish. ''Zostera'' often forms beds in bay mud in the estuarine setting. It is an important food for brant geese and wigeon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Lettuce
The sea lettuces comprise the genus ''Ulva'', a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus ''Ulva'' is ''Ulva lactuca'', wikt:lactuca, ''lactuca'' being Latin for "lettuce". The genus also includes the species previously classified under the genus ''Enteromorpha'', the former members of which are known under the common name green nori. Description Individual blades of ''Ulva'' can grow to be more than 400 mm (16 in) in size, but this occurs only when the plants are growing in sheltered areas. A macroscopic alga which is light to dark green in colour, it is attached by disc holdfast. Their structure is a leaflike flattened thallus. Nutrition and contamination Sea lettuce is eaten by a number of different sea animals, including manatees and the sea slugs known as sea hares. Many species of sea lettuce are a food source for humans in Scandinavia, Great Britain, Ireland, China, and Japan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of '' Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; a wasting disease in predators of purple urchins has led to a urchin population surge which destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global agricultural practic ...

Spearfishing
Spearfishing is a method of fishing that involves impaling the fish with a straight pointed object such as a spear, gig or harpoon. It has been deployed in artisanal fishing throughout the world for millennia. Early civilisations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks. Modern spearfishing usually involves the use of underwater swimming gear and slingshot-like elastic powered spearguns or compressed gas powered pneumatic spearguns, which launch a tethered underwater projectile to strike the target fish. Specialised techniques and equipment have been developed for various types of aquatic environments and target fish. Spearfishing may be done using free-diving, snorkelling or scuba diving techniques, but spearfishing while using scuba equipment is illegal in some countries. The use of mechanically powered spearguns is also outlawed in some countries and jurisdictions such as New Zealand. Spearfishing uses no bait and is ...
