Estimates Of Harvest Potential And Distribution Of The Deep Sea Red Crab, Chaceon Quinquedens, In The North Central Gulf Of Mexico, Richard Waller, Harriet Perry, Christine Trigg, James Mcbee, Robert Erdman, Norman Blake
Gulf and Caribbean Research
Harvest potential, relative abundance, and geographic and bathymetric distribution are discussed for the red crab, Chaceon quinquedens, in the northcentral Gulf of Mexico. Harvest potential is expressed as the number of trapable crabs present on fishing grounds defined as depths ranging from 677 m to 1043 m between 87.5o and 88.5oW longitude. Using various estimates of the effective fishing area (EFA) of a trap, the number of trapable red crabs on the fishing grounds ranged from 3.7 x 106 to 10.7 x 106. Estimatesofcrabnumberssuggest there is a potential for commercial harvest in the …
Pseudione Overstreeti, New Species (Isopoda: Epicaridea: Bopyridae), A Parasite Of Callichirus Islagrande (Decapoda: Anomura: Callianassidae) From The Gulf Of Mexico, Daniel L. Adkison, Richard W. Heard
Pseudione Overstreeti, New Species (Isopoda: Epicaridea: Bopyridae), A Parasite Of Callichirus Islagrande (Decapoda: Anomura: Callianassidae) From The Gulf Of Mexico, Daniel L. Adkison, Richard W. Heard
Gulf and Caribbean Research
Pseudione overstreeti, new species, is a common bopyrid that infests the branchial chamber of the beach ghost shrimp, Callichirus islagrande, occurring along beaches of the Gulf of Mexico from Cape San Blas, Florida to Paraiso, Tabasco, Mexico. Like other members of the genus Pseudione that infest callianassid shrimps, the female of P. overstreeti is characterized by biramous terminal appendages which result from the combination of uniramous uropods with the closely associated lateral plates of pleomere 6. From the other members of the genus Pseudione occurring on callianassid hosts, P. overstreeti is distinguished by the distinctive development of the …
A Pugheaded Cobia (Rachycentron Canadum) From The Northcentral Gulf Of Mexico, James S. Franks
A Pugheaded Cobia (Rachycentron Canadum) From The Northcentral Gulf Of Mexico, James S. Franks
Gulf and Caribbean Research
A pugheaded cobia (Rachycentron canadum) captured in the northcentral Gulf of Mexico represents the first record of pugheadedness in cobia. The specimen, a 4-year-old gravid female, exhibited considerable distortion of the premaxillary and maxillary bones, with the length of the snout 46% shorter than that of a normal cobia of the same length. The anomaly had no apparent effect on feeding, since the stomach contained a substantial amount of food, and the fish was the same length expected of a normal 4-year-old cobia.
A Note On Bycatch Associated With Deepwater Trapping Of Chaceon In The Northcentral Gulf Of Mexico, Harriet Perry, Richard Waller, Christine Trigg, James Mcbee, Robert Erdman, Norman Blake
A Note On Bycatch Associated With Deepwater Trapping Of Chaceon In The Northcentral Gulf Of Mexico, Harriet Perry, Richard Waller, Christine Trigg, James Mcbee, Robert Erdman, Norman Blake
Gulf and Caribbean Research
Bycatch associated with deepwater trapping of Chaceon is reported for outer shelf and slope waters of the northcentral Gulf of Mexico. Bycatch was dominated by the isopod, Bathynomus giganteus. Other crustacean megafauna consisted of the majid crab, Rochinia crassa, and the portunid crabs, Benthochascon schmitti and Bathynectes longispina. Finfish bycatch included hagfish, Eptatretus springeri, deepwater shark, Centrophorus uyato and hake, Urophycis cirrata.
