Shoal Bass
The shoal bass (''Micropterus cataractae'') is a species of freshwater fish in the sunfish family (Centrarchidae) of order Centrarchiformes. One of the black basses, it is native to waters in Florida and Georgia.Williams, J. D., and G. H. Burgess. 1999. A new species of bass, Micropterus cataractae (Teleostei: Centrarchidae), from the Apalachicola River basin in Alabama, Florida, and Georgia. Bulletin of the Florida Museum of Natural History 42(2):81–114. It is also occasionally found in rivers and streams of East Alabama where it has been declared an endangered species and cannot legally be kept if caught by fishermen. Of typical size for a black bass, ''M. cataractae'' reaches a maximum recorded length of and a maximum published weight of 8 pounds, 12 ounces. Only described for the first time in 1999, ichthyologists are still expanding what is known about the species. The shoal bass is often confused with the redeye bass, due to its red-tinted eyes. It is also often confuse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint River
The Flint River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 15, 2011 river in the U.S. state of Georgia. The river drains of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the Gulf Coastal Plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee rivers, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont, it is considered especially scenic, flowing unimpeded for over . Historically, it was also called the Thronateeska River. Description The Flint River rises in west central Georgia in the city of East Point in southern Fulton County on the southern outskirts of the Atlanta metropolitan area as ground seepage.

Suwannee Bass
The Suwannee bass (''Micropterus notius'') is a species of freshwater fish in the sunfish family (biology), family (Centrarchidae) of order (biology), order Centrarchiformes. One of the black basses, This species is native to just two river systems in Florida and Georgia (U.S. State), Georgia, although it has been introduced species, introduced elsewhere. Description The Suwannee bass is a rather small species compared to its congeners and has a deep body with a large mouth in which the maxilla is placed beneath the eye and there is a circular patch of teeth on the tongue. The base of the soft part of the dorsal fin and the anal fin are scaled. They are mostly brown in colour marked with a dozen olive blotches on the flanks. These blotches are wider than the gaps between them towards the head but they merge towards the tail eventually creating a horizontal band near the caudal peduncle. There is a large blotch at the base of the caudal fin which has a pale margin, this is more ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Point Lake
West Point Lake is a man-made reservoir located mostly in west-central Georgia on the Chattahoochee River and maintained by the U.S. Army Corps of Engineers (USACE). The Chattahoochee river flows in from the north, before flowing through the West Point Dam, which impounds the lake, and continuing to Columbus, Georgia. Of the four major USACE lakes in the ACF River Basin, West Point Lake is the smallest by area containing of water, and has the second shortest shoreline at . The purposes of the reservoir are to provide flood control, hydroelectric power, and water storage to aid the navigation of the lower Chattahoochee. History Authorized by the Flood Control Act of 1962, West Point Lake was built for several purposes and cost an estimated $105 million. Two major uses of the lake prescribed are Hydroelectric Power, power generation and recreation. The smaller percentage uses are: flood control, Fish and Wildlife, Area Redevelopment, and Navigation.

Lake Blackshear
Lake Blackshear is a man-made lake on the Flint River in Georgia created by a dam that was constructed from 1925 to 1930. The lake was named after General David Blackshear. The Crisp County Power Dam, also known as the Warwick Dam, was the first county owned, constructed, and operated power dam in the United States, requiring an amendment to the Georgia State Constitution to make the project legally possible. It came online in August, 1930, under the authority of the Crisp County Power Commission. The lake is approximately long and varies in width, but is rarely more than one mile (1.6 km) wide; it covers approximately . It was named for David Blackshear, the founder of Fort Early. When the dam was constructed, little effort was made to cut the trees that would soon be underwater. It was believed that the trees would soon die and decompose once submerged. While this was true for many of the trees, there are still many living Cypress trees in the middle of the lake, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chattahoochee River
The Chattahoochee River () is a river in the Southeastern United States, Southeastern United States. It forms the southern half of the Alabama and Georgia (U.S. state), Georgia border, as well as a portion of the Florida and Georgia border. It is a tributary of the Apalachicola River, a relatively short river formed by the confluence of the Chattahoochee and Flint River (Georgia), Flint rivers and emptying from Florida into Apalachicola Bay in the Gulf of Mexico. The Chattahoochee River is about long. The Chattahoochee, Flint, and Apalachicola rivers together make up the Apalachicola–Chattahoochee–Flint River Basin (ACF River Basin). The Chattahoochee makes up the largest part of the ACF's drainage basin.

Shoal
In oceanography, geomorphology, and Earth science, geoscience, a shoal is a natural submerged ridge, bank (geography), bank, or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared crest and trough, troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar to, or quite different from, how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, the term refers to either any relatively shallow place in a stream ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chipola River

Scale (zoology)
In zoology, a scale (; ) is a small rigid plate (animal anatomy), plate made out of keratin that grows out of Vertebrate animals' skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, made out of chitin instead of keratin, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to the shape and class (biology), class of an animal. Fish scales Fish scales are skin, dermally derived, specifically in the mesoderm. This fact distinguishes them from reptile scales paleontologically. Genetically, the same genes involved in tooth and hair development in mammals are also involved in scale development.

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
