Relative Abundance Of Pelagic Sharks In The Western North Atlantic Ocean, Including The Gulf Of Mexico And Caribbean Sea, Enric Cortes, Craig A. Brown, Lawrence R. Beerkircher
Relative Abundance Of Pelagic Sharks In The Western North Atlantic Ocean, Including The Gulf Of Mexico And Caribbean Sea, Enric Cortes, Craig A. Brown, Lawrence R. Beerkircher
Gulf and Caribbean Research
Little information exists on the status of pelagic shark populations in the Atlantic Ocean, especially in the Gulf of Mexico and Caribbean Sea. We derived indices of relative abundance for pelagic sharks based on mandatory logbooks and observer reports from a scientific observer program of the United States (US) pelagic longline fleet. Time series data from the pelagic longline logbook program (1986-2005) and the pelagic longline observer program (1992-2005) were standardized with Generalized Linear Model (GLM) procedures. Declines in relative abundance for the 6 pelagic shark species or genera examined in the logbook data analysis ranged from 43% for mako …
Patterns Of Vertical Habitat Use By Atlantic Blue Marlin (Makaira Nigricans) In The Gulf Of Mexico, Richard T. Kraus, Jay R. Rooker
Patterns Of Vertical Habitat Use By Atlantic Blue Marlin (Makaira Nigricans) In The Gulf Of Mexico, Richard T. Kraus, Jay R. Rooker
Gulf and Caribbean Research
We examined data from pop-up archival transmitting (PAT) tags (n = 18) to characterize aspects of vertical habitat use by blue marlin (Makaira nigricans) from the Gulf of Mexico (GOM). Two of these tags were recovered and provided fine-scale information about diving patterns and the relationship between time at depth and temperature. Similar to previous studies, blue marlin in the GOM spent most of their time at the surface and at temperatures within 3° C of surface temperatures. Time at depth was multimodal and the magnitude of the smaller modes was dependent upon the strength and depth …
Distribution Of Molidae In The Northern Gulf Of Mexico, Gregory L. Fulling, Dagmar Fertl, Kevin Knight, Wayne Hoggard
Distribution Of Molidae In The Northern Gulf Of Mexico, Gregory L. Fulling, Dagmar Fertl, Kevin Knight, Wayne Hoggard
Gulf and Caribbean Research
We compiled all available sighting, stranding and bycatch data for the Family Molidae (molas) in the northern Gulf of Mexico (NGOM) to assess spatial and temporal distribution. Overall, 483 records were collected from shipboard and aerial surveys, fisheries bycatch, and strandings. Molas were recorded year-round, with a ubiquitous distribution in both nearshore and offshore waters. Ocean sunfish (Mola mola) were sighted with greatest frequency during the winter (December thru April) in sea surface temperature < 24° C. Potential reasons for increased sightings during winter may be related to the lack of a well-defined thermocline in the NGOM; the species' "basking" behavior associated with thermoregulation; and oxygen replenishment after long, deep dives to oxygen-deficient depths.
Management In The Gulf And Caribbean: Mosaic Or Melting Pot?, Patrick Mcconney, Hazel A. Oxenford, Milton Haughton
Management In The Gulf And Caribbean: Mosaic Or Melting Pot?, Patrick Mcconney, Hazel A. Oxenford, Milton Haughton
Gulf and Caribbean Research
Does ''managing large pelagic fishes" mean the same thing across the diversity of maritime jurisdictions, governance arrangements, economies, languages, cultures, scales of operation and other features of the Gulf and Caribbean region? It would be surprising if it did. Yet international fisheries management urges this mosaic of management to become a melting pot; at least integrated, even if differentiated. This paper examines some themes underlying whether a mosaic or melting pot is the most apt metaphor for where we are, and are headed, in attempts to manage large pelagic fishes in the region. We pay particular attention to the multi-dimensional …
