Application Of Pop-Up Satellite Archival Tag Technology To Estimate Postrelease Survival Of White Marlin (Tetrapturus Albidus) Caught On Circle And Straight-Shank ("J") Hooks In The Western North Atlantic Recreational Fishery, Az Horodysky, John Graves Jan 2005

Application Of Pop-Up Satellite Archival Tag Technology To Estimate Postrelease Survival Of White Marlin (Tetrapturus Albidus) Caught On Circle And Straight-Shank ("J") Hooks In The Western North Atlantic Recreational Fishery, Az Horodysky, John Graves

VIMS Articles

Short-duration (5- or 10-day) deployments of pop-up satellite archival tags were used to estimate survival of white marlin (Tetrapturus albidus) released from the western North Atlantic recreational fishery. Forty-one tags, each recording temperature, pressure, and light level readings approximately every two minutes for 5-day tags (n=5) or four minutes for 10-day tags (n=36), were attached to white marlin caught with dead baits rigged on straight-shank ("J") hooks (n=21) or circle hooks (n = 20) in offshore waters of the U.S. Mid-Atlantic region, the Dominican Republic, Mexico, and Venezuela. Forty tags (97.8%) transmitted data to the satellites of the Argos system, …


Observations On The Life History Of The Barndoor Skate, Dipturus Laevis, On Georges Bank (Western North Atlantic), Todd Gedamke, William D. Dupaul, John A. Musick Jan 2005

Observations On The Life History Of The Barndoor Skate, Dipturus Laevis, On Georges Bank (Western North Atlantic), Todd Gedamke, William D. Dupaul, John A. Musick

VIMS Articles

The barndoor skate (Dipturus laevis) has been reported to be close to extinction in parts of its northern range and is believed to be particularly vulnerable to fishing mortality due to its relatively large size. A lack of basic life history information, however, has hampered an accurate assessment and management of north Atlantic populations. In an attempt to fill this void, information was collected from 2 310 specimens caught during commercial sea scallop dredging in the southern section of Georges Bank Closed Area II. Eighty-seven fish were determined to be mature from a visual inspection of reproductive tracts and the …

Quantification Of Drag And Lift Imposed By Pop-Up Satellite Archival Tags And Estimation Of The Metabolic Cost To Cownose Rays (Rhinoptera Bonasus), Donna S. Grusha, Mark R. Patterson Jan 2005

Quantification Of Drag And Lift Imposed By Pop-Up Satellite Archival Tags And Estimation Of The Metabolic Cost To Cownose Rays (Rhinoptera Bonasus), Donna S. Grusha, Mark R. Patterson

The recent development of the p)p-up satellite archival tag (PSAT) has allowed the collection of information on a tagged animal, such as geolocation, pressure (depth), and ambient water temperature. The success of early studies, where PSATs were used on pelagic fishes, has spurred increasing interest in the use of these tags on a large variety of species and age groups. However, some species and age groups may not be suitable candidates for carrying a PSAT because of the relatively large size of the tag and the consequent energy cost to the study animal. We examined potential energetic costs to carrying …


Toward Identification Of Larval Sailfish (Istiophorus Platypterus), White Marlin (Tetrapturus Albidus), And Blue Marlin (Makaira Nigricans) In The Western North Atlantic Ocean, Stacy A. Luthy, Robert K. Cowen, Joseph E. Serafy, Jan Mcdowell Jan 2005

VIMS Articles

The identification of larval istiophorid billfishes from the western North Atlantic Ocean has long been problematic. In the present study, a molecular technique was used to positively identify 27 larval white marlin (Tetrapturus albidus), 96 larval blue marlin (Makaira nigricans), and 591 larval sailfish (Istiophorus platypterus) from the Straits of Florida and the Bahamas. Nine morphometric measurements were taken for a subset of larvae (species known), and lower jaw pigment patterns were recorded on a grid. Canonical variates analysis (CVA) was used to reveal the extent to which the combination of morphometric, pigment pattern, and month of capture information was …
