Abstract— Reproductive biology of the cobia, Rachycentron canadum , is de-scribed from four coastal areas in the southern United States. Samples were obtained from recreational fi shermen between December 1995 and Novem-ber 1997 from the southeastern United States (Morehead City, NC, to Cape Canaveral, FL), the eastern Gulf of Mexico (Ft. Myers to Crystal River, FL), the north-central Gulf of Mexico (Destin, FL, to Chandeleur Islands, LA) and the western Gulf of Mexico (Port Aransas, TX… 
Inshore spawning of cobia (Rachycentron canadum) in South Carolina
We documented inshore spawning of the recreationally important cobia (Rachycentron canadum) in Port Royal Sound (PRS) and St. Helena Sound (SHS), South Carolina, during the period from April to June
Reproductive biology of the commercially and recreationally important cobia Rachycentron canadum in northeastern Australia
The reproductive biology of 315 cobia from northeastern Australia was studied for an 18-month period, and provides valuable data for future population assessments of cobia throughout the Indo-Pacific.
Assessment of cobia, Rachycentron canadum, in the waters of the U.S. Gulf of Mexico
This assessment applies to cobia (Rachycentron canadum) located in the territorial waters of the U.S. Gulf of Mexico. Separation of the Gulf of Mexico and Atlantic Ocean is defined by the seaward
Reproductive biology of Caspian vimba, Vimba vimba (L.), in the coastal waters of the southwestern Caspian Sea
The Caspian vimba is a total spawner with variable spawning dependent on environmental factors and seasonal changes in the gonadosomatic index, gonad histological status, size frequency distribution of oocytes, and the fecundity of the species were studied.
Mariculture-induced introduction of cobia Rachycentron canadum (Linnaeus, 1766), a large predatory fish, in the Tropical Eastern Pacific.
This work presents the first report of R. canadum in the Colombian Pacific coast, ca.
Reproductive biology of female Oxynoemacheilus bergianus (Actinopterygii: Cypriniformes: Nemacheilidae) from the Jajrud River, the Namak Lake basin, central Iran
It was concluded that this fish has a relatively prolonged active reproductive period and the present knowledge could be used in the conservation and management strategies intended to maintain the O. bergianus stock.
F ecundity and spawning frequency of Cobia, Rachycentron canadum (Linnaeus, 1766) from the North West coast of India
The Ova Diameter study indicated that Cobia follows a protracted spawning season with the individual spawning more than once in a season.
Reproductive characteristics of northern pike, Esox lucius (Actinopterygii: Esociformes: Esocidae), in the Anzali Wetland, southwest Caspian Sea
Background. Temporal variability in fi sh reproductive features is infl uenced by environmental and spatial variations. Given the wide distribution of northern pike, Esox lucius Linnaeus, 1758, in
Fecundity and spawning frequency of Cobia, Rachycentron canadum (Linnaeus, 1766) from the North West coast of India
An attempt has been made to provide some vital aspects on spawning frequency and fecundity of Cobia based on the samples collected from fishery exploratory surveys and from the landing centers at
Population genetics of Cobia (Rachycentron canadum): implications for fishery management along the coast of the southeastern United States
The recapture of stocked fish within their release estuary 2 years after release indicates that some degree of estuarine fidelity occurs within these inshore aggregations and supports the detection of their unique genetic structure at the population level.


Gonadal Maturation in the Cobia, Rachycentron canadum, from the Northcentral Gulf of Mexico
Gonadal maturation of cobia, Rachycentron canadum, was evaluated by examining 508 specimens from its recreational fishery and it was determined that females were ripe from May through September, with atretic oocytes occurring in some fish from July through October.
Age and Growth of Cobia, Rachycentron canadum , from the Northeastern Gulf of Mexico
Large, migratory, coastal pelagic fish of the monotypic family Rachycentridae are distributed worldwide in tropical and subtropical seas, except for the eastern Pacific.
Synopsis of biological data on the cobia Rachycentron canadum (Pisces: Rachycentridae)
Information on the biology and fisheries of cobia, Rachycentron canadum, is compiled and reviewed in the FAD species synopsis style. Topics include taxonomy, morphology, distribution, reproduction,
Morphological and histological data showed that oocytes were continually recruited from March through the end of September, and the percentages of vitellogenic and fully yolked oocytes did not decline during the spawning season, and Laboratory studies showed that this species is capable of repeated spawns.
Spawn frequency is one of the missing links in an assessment of the reproduction of skipjack populations, and two methods have been developed for measuring the spawning rate of multi­ ple spawning marine fishes.
Age, Growth and Fecundity of the Cobia, Rachycentron canadum, from Chesapeake Bay and Adjacent Mid‐Atlantic Waters
Abstract Age, growth, fecundity, and distribution of cobia, Rachycentron canadum, were studied. Data were collected primarily from lower Chesapeake Bay and adjacent mid-Atlantic waters. Age analysis
The multiple spawning pattern of weakfish in the Chesapeake Bay and Middle Atlantic Bight
Typical methods of assessing reproduction, such as the GSI and macroscopic gonad stages, are inadequate for this species if not used in conjunction with more detailed methods such as histology.
Spawning rhythms of common snook in Florida
Common snook Centropomus undecimaliswere sampled monthly from the Jupiter–Lake Worth area of Florida's Atlantic coast during 1989 and 1991 (1452 fish) and from Tampa Bay on Florida's Gulf of Mexico
Batch fecundity of Atlantic mackerel, Scomber scombrus L.
An extensive trawl survey of the Western mackerel stock in the NE Atlantic was undertaken in the 1989 spawning season and it is suggested that as spawning fish migrate northwards the batch size decreases with progress of the spawning season.
Spawning of the cobia, Rachycentron canadum , in the Chesapeake Bay area, with observations of juvenile specimens
Pelagic eggs collected in Atlantic coastal waters adjacent to Chesapeake Bay have been identified as those of the cobia, Rachycentron canadum (Linnaeus), and the single large oil globule had a mean diameter of 0.38 mm.
