Rockfish
Rockfish is a common term for several species of fish, referring to their tendency to hide among rocks. The name rockfish is used for many kinds of fish used for food. This common name belongs to several groups that are not closely related, and can be arbitrary. Specific examples of fish termed rockfish include: *The family Sebastidae, marine fishes that inhabit oceans around the world. They may be included in the family Scorpaenidae. ** ''Sebastes'', Monterey Bay Aquarium. a commercially important genus of fish in the Sebastidae inhabiting mainly the North Pacific, but with a few species in the North Atlantic and southern oceans * '''', a genus of fis ...

Sebastes
''Sebastes'' is a genus of marine ray-finned fish belonging to the subfamily Sebastinae part of the family Scorpaenidae, most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish instead. They are found in the Atlantic and Pacific Oceans. Taxonomy ''Sebastes'' was first described as a genus in 1829 by the French zoologist Georges Cuvier, the Dutch ichthyologist Pieter Bleeker designated ''Perca norvegica'', which may have been originally described by the Norwegian zoologist Peter Ascanius in 1772, as the type species in 1876. The genus is the type genus of both the tribe Sebastini and the subfamily Sebastinae, although some authorities treat these as the subfamily Sebastinae and the family Sebastidae, separating the Sebastidae as a distinct family from the Scorpaenidae. but other authorities place it in the Perciformes in the suborder Scorpaenoidei. Some authorities subdivide this large genus into subgenera as follows: * ''Sebastes'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madeira Rockfish
The Madeira rockfish (''Scorpaena maderensis'') is a species of scorpionfish (Scorpaenidae) in the genus ''Scorpaena,'' found in the coastal waters of the eastern Atlantic Ocean and the Mediterranean Sea. This species reaches a length of around SL. The species was described by Achille Valenciennes in 1833 after a specimen from Madeira. Although ''S. maderensis'' is well represented in the areas that it is found, many key aspects of its biology are still unknown. Description The Madeira rockfish grows between 4.8 cm (1.89 in) and 13.1 cm (5.16 in) and weigh between 1.7 and 48.1 g, with males being larger in both categories. Females achieve their maximum size faster and live longer than males. The maximum recorded length for males and females is around 15 cm (5.91 in) and 9.0 cm (3.54 in) respectively. ''S. maderensis''exhibits many similar characteristics to other ''Scorpaena'', such as spiny fins and a reddish-brown splotched color but th ...

Scorpaena
''Scorpaena'' is a widespread genus of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. Taxonomy ''Scorpaena'' was first described as a genus in 1758 by Carl Linnaeus in the 10th Edition of his ''Systema Naturae''. In 1876 Pieter Bleeker designated ''S. porcus'' as the type species of the genus. The genus name is based on the Greek word for a scorpion, ''skorpaina'', an allusion to the venomous spines Linnaeus mentioned in his description of ''S. scrofa''. Species The 65 recognized species in this genus are: Characteristics ''Scorpaena'' scorpionfishes have a very bony head which is armed with numerous spines. There is a horizontal bony ridge beneath the eyes with 1-4 spines. They have an occipital pit. The uppermost spine on the preoperculum is the longest. There are patches of teeth on the roof of the mouth and at its sides. There are 12 spines and between 7 and 10 soft rays in the dorsal fin while the anal fin has 3 spines and 5 soft ra ...

Sebastidae
Sebastinae is a subfamily of marine fish belonging to the family Scorpaenidae in the order Scorpaeniformes. Their common names include rockfishes, rock perches, ocean perches, sea perches, thornyheads, scorpionfishes, sea ruffes and rockcods. Despite the latter name, they are not closely related to the cods in the genus ''Gadus'', nor the rock cod, ''Lotella rhacina''. Taxonomy Sebastinae, or Sebastidae, was first formally recognised as a grouping in 1873 by the German naturalist Johann Jakob Kaup. Some authorities recognise this family as distinct from Scorpaenidae. FishBase, a finfish database generated by a consortium of academic institutions, does, but the United States Federal government's Integrated Taxonomic Information System and the 5th Edition of ''Fishes of the World'' do not, FotW classify it as a subfamily of the Scorpaenidae. Tribes and genera Sebastinae is divided into two tribes and seven genera: * Tribe Sebastini Kaup, 1873 ** ''Helicolenus'' Goode & Bean, 1 ...

Myliobatis Goodei
The Southern eagle ray (''Myliobatis goodei''), sometimes known as the Southern eagle fish or the rockfish, is a ray species in the family Myliobatidae. It lives in waters just off of the Atlantic coast, from the tip of Florida down to Argentina, inhabiting estuaries or bays to give birth during spring and summer and migrating to the open sea in autumn and winter. It has an average width of 99 centimeters, and a length of 60 centimeters. It is often confused with the bullnose ray, a related species in the genus '' Myliobatis'', due to the two species' similarities in appearance. Taxonomy Samuel Garman described the southern eagle ray in 1885. Distribution and habitat The Southern eagle ray lives on various parts of the Atlanta coast. Sightings have been reported from the coast of Southern Mexico all the way down to Argentina, as well as on the coast of Florida. The specific countries that the Southern eagle ray is native to are Argentina, Belize, Brazil, Colombia, Cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venomous
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called envenomation. Venom is often distinguished from poison, which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and toxungen, which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and haemotoxins, which disrupt blood clotting. Venomous animals cause tens of thousan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Striped Bass
The striped bass (''Morone saxatilis''), also called the Atlantic striped bass, striper, linesider, rock, or rockfish, is an anadromous perciform fish of the family Moronidae found primarily along the Atlantic coast of North America. It has also been widely introduced into inland recreational fisheries across the United States. Striped bass found in the Gulf of Mexico are a separate strain referred to as Gulf Coast striped bass. The striped bass is the state fish of Maryland, Rhode Island, and South Carolina, and the state saltwater (marine) fish of New York, New Jersey, Virginia, and New Hampshire. The history of the striped bass fishery in North America dates back to the Colonial period. Many written accounts by some of the first European settlers describe the immense abundance of striped bass, along with alewives, traveling and spawning up most rivers in the coastal Northeast. Morphology and lifespan The striped bass is a typical member of the family Moronidae in shap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaenidae
The Scorpaenidae (also known as scorpionfish) are a family of mostly marine fish that includes many of the world's most venomous species. As their name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus '' Scorpaenichthys'', which belong to a separate, though related, family, Cottidae. Taxonomy Scorpaenidae was described as a family in 1826 by the French naturalist Antoine Risso. The family is included in the suborder Scorpaenoidei of the order Scorpaeniformes in the 5th Edition of ''Fishes of the World'' but other authorities place it in the Perciformes either in the suborder Scorpaenoidei or the superfamily Scorpaenoidea. The subfamilies of this family are treated as valid families by some authorities. Subfamilies and trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epinephelinae
Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes. Not all serranids are called "groupers"; the family also includes the sea basses. The common name "grouper" is usually given to fish in one of two large genera: ''Epinephelus'' and ''Mycteroperca''. In addition, the species classified in the small genera ''Anyperidon'', ''Cromileptes'', ''Dermatolepis'', ''Graciela'', ''Saloptia'', and ''Triso'' are also called "groupers." Fish in the genus ''Plectropomus'' are referred to as "coral groupers." These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus ''Alphestes''), the hinds (genus ''Cephalopholis''), the lyretails (genus ''Variola''), and some other small genera (''Gonioplectrus'', ''Niphon'', ''Paranthias'') are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper." Nonetheless, the word "grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salvelinus
''Salvelinus'' is a genus of Salmonidae, salmonid fish often called char or charr; some species are called "trout". ''Salvelinus'' is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea. Most char may be identified by light-cream, pink, or red spots over a darker body. Scales tend to be small, with 115-200 along the lateral line. The pectoral, pelvic, anal, and the lower aspect of caudal fins are trimmed in snow white or cream leading edges. Many members of this genus are popular sport fish, and a few, such as lake trout (''S. namaycush'') and arctic char (''S. alpinus'') are objects of commercial fisheries and/or aquaculture. Occasionally, such fish escape and become invasive species. Deepwater char are small species of char living below 80 m in the deep areas of certain lakes. They are ...
