Raymond is a town in Cumberland County, Maine, United States. The population was 4,536 at the 2020 census. It is a summer recreation area and is part of the Portland– South Portland–Biddeford, Maine metropolitan statistical area. Raymond Neck is the landing for the ferry to the town of Frye Island in Sebago Lake. The Raymond school system is currently affiliated with the Windham school system in a district known as RSU 14. History Raymondtown Plantation was granted in 1767 by the Massachusetts General Court to the descendants of Captain William Raymond of Beverly, Massachusetts, and his militia. It was the second attempt to repay the troop (or heirs) for service under Governor Sir William Phipps during the Battle of Quebec in 1690. A township had been awarded them in 1735 called Beverly-Canada (now Weare, New Hampshire), but in 1741 descendants of John Mason proved a prior claim.

Golden Shiner
The golden shiner (''Notemigonus crysoleucas'') is a cyprinid fish native to eastern North America. It is the sole member of its genus. Much used as a bait fish, it is probably the most widely pond-cultured fish in the United States. It can be found in Quebec, and its French name is "Mené jaune" or "Chatte de l'Est". Taxonomy It is the only North American member of the Old World clade within subfamily Leuciscinae. Description Though it has been known to reach lengths of , in the wild the golden shiner is usually between long. The body is laterally compressed (deep-bodied). The back is dark green or olive, and the belly is a silvery white. The sides are silver in smaller individuals, but golden in larger ones. There can be a faint dusky stripe along the sides.

Rainbow Smelt
The rainbow smelt (''Osmerus mordax'') is a North American species of fish of the family Osmeridae. Walleye, trout, and other larger fish prey on these smelt. The rainbow smelt prefer juvenile ciscoes, zooplankton such as calanoid copepods ('' Leptodiaptomus ashlandi'', '' L. minutus'', '' L. sicilis''), and other small organisms, but are aggressive and will eat almost any fish they find. They are anadromous spring spawners and prefer clean streams with light flow and light siltation. The rainbow smelt face several barriers. They are weak swimmers and struggle to navigate fish ladders preventing them from making it past dams to the headwater streams where they spawn. The rise in erosion and dams helped to decimate the smelt population in the 1980s. There are currently plans to try to reduce damming and to help control erosion. Description The body of the rainbow smelt is slender and cylindrical. It has a silvery, pale green back and is iridescent purple, blue, and pink on the ...

Burbot
The burbot (''Lota lota'') is the only gadiform (cod-like) freshwater fish Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of .... It is also known as bubbot, mariah, loche, cusk, freshwater cod, freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, and eelpout. The species is closely related to the marine common ling and the cusk (fish), cusk. It is the monotypic, only member of the genus ''Lota''. For some time of the year, the burbot lives under ice, and it requires frigid temperatures to breed. Etymology The name burbot comes from the Latin word ''barba'', meaning beard, referring to its single chin whisker, or barbel (anatomy), barbel. Its generic and specific names, ''Lota lota'', comes from the old French ''lotte'' fish, which is also named "barbot" in Old French. ...

Thermocline
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) in which temperature changes more drastically with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below. Depending largely on season, latitude, and turbulent mixing by wind, thermoclines may be a semi-permanent feature of the body of water in which they occur, or they may form temporarily in response to phenomena such as the radiative heating/cooling of surface water during the day/night. Factors that affect the depth and thickness of a thermocline include seasonal weather variations, latitude, and local environmental conditions, such as tides and currents. Oceans Most of the heat energy of the sunlight that strikes the Earth is absorbed in the first few centimeters at the ocean's surface, which ...

Oxygen Saturation
Oxygen saturation (symbol SO2) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium at the given temperature. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. The standard unit of oxygen saturation is percent (%). Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO2) is commonly measured using pulse oximetry. Tissue saturation at peripheral scale can be measured using NIRS. This technique can be applied on both muscle and brain. In medicine In medicine, oxygen saturation refers to ''oxygenation'', or when oxygen molecules () enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation (() sats) measures the percentage of hemoglobin binding s ...

American Eel
The American eel (''Anguilla rostrata'') is a facultative catadromous fish found on the eastern coast of North America. Freshwater eels are fish belonging to the elopomorph superorder, a group of phylogenetically ancient teleosts. The American eel has a slender, snake-like body that is covered with a mucus layer, which makes the eel appear to be naked and slimy despite the presence of minute scales. A long dorsal fin runs from the middle of the back and is continuous with a similar ventral fin. Pelvic fins are absent, and relatively small pectoral fins can be found near the midline, followed by the head and gill covers. Variations exist in coloration, from olive green, brown shading to greenish-yellow and light gray or white on the belly. Eels from clear water are often lighter than those from dark, tannic acid streams. The eel lives in fresh water and estuaries and only leaves these habitats to enter the Atlantic Ocean to make its spawning migration to the Sargasso Sea. Spa ...

Pumpkinseed
The pumpkinseed (''Lepomis gibbosus''), also referred to as pond perch, common sunfish, punkie, sunfish, sunny, and kivver, is a small/medium-sized North American freshwater fish of the genus ''Lepomis'' (true sunfishes), from family Centrarchidae (sunfishes, crappies and black basses) in the order Perciformes. Distribution and habitat The pumpkinseed's natural range in North America is from New Brunswick down the east coast to South Carolina. It then runs inland to the middle of North America, and extends through Iowa and back through Pennsylvania. Pumpkinseed sunfish have however been introduced throughout most of North America. They can now be found from Washington and Oregon on the Pacific Coast to Georgia on the Atlantic Coast. Yet they are primarily found in the northeastern United States and more rarely in the south-central or southwestern region of the continent.

Banded Killifish
The banded killifish (''Fundulus diaphanus'') is a North American species of temperate freshwater killifish belonging to the genus ''Fundulus'' of the family Fundulidae. Its natural geographic range extends from Newfoundland to South Carolina, and west to Minnesota, including the Great Lakes drainages.Page, Lawrence M. and Brooks M. Burr (1991), ''Freshwater Fishes'', p. 216, Houghton Mifflin, New York. This species is the only freshwater killifish found in the northeastern United States. While it is primarily a freshwater species, it can occasionally be found in brackish water. Etymology The common name, "banded killifish", commonly refers to the distinct black and white vertical bandings found along their sides. The Latin genus name ''Fundulus'' is the diminutive of ''fundus'', which means "bottom," and the specific name ''diaphanus'' means "transparent" in Greek.Chippett, Jamie D. 2003.

Brown Bullhead
The brown bullhead (''Ameiurus nebulosus'') is a fish of the family Ictaluridae that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (''Ameiurus melas'') and yellow bullhead (''Ameiurus natalis''). It was originally described as ''Pimelodus nebulosus'' by Charles Alexandre Lesueur in 1819, and is also referred to as ''Ictalurus nebulosus''. The brown bullhead is also widely known as the "mud pout", "horned pout", "hornpout", or simply "mud cat", a name also used with the other bullhead species. The brown bullhead is important as a clan symbol of the Ojibwe people. In their tradition, the bullhead or is one of six beings that came out of the sea to form the original clans. Appearance The brown bullhead grows to be approximately in length and is a darker brown-green dorsally, growing lighter green and yellow towards the ventral surface. The belly is off-white or cream, and the fish has no scales. Additionally, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
