Green Sturgeon Physical Habitat Use in the Coastal Pacific Ocean
The green sturgeon (Acipenser medirostris) is a highly migratory, oceanic, anadromous species with a complex life history that makes it vulnerable to species-wide threats in both freshwater and at sea. Green sturgeon population declines have preceded legal protection and curtailment of activities in marine environments deemed to increase its extinction risk. Yet, its marine habitat is poorly un...
متن کاملScaling Acoustic Telemetry of Bluefish in an Estuarine Observatory: Detection and Habitat Use Patterns
—We telemetered adult bluefish Pomatomus saltatrix via a fixed estuarine hydrophone array to assess estuarine habitat use and determine the feasibility of using this approach coastwide. Eighteen bluefish (286–622 mm fork length) were surgically implanted with ultrasonic tags transmitting at either 2-s or 5-s intervals. The fish were monitored during their stay within a temperate estuary by hydr...
متن کاملHabitat use patterns of newly settled spotted seatrout in estuaries of the north-western Gulf of Mexico
This study examined habitat use patterns of newly settled spotted seatrout Cynoscion nebulosus (Cuvier) across several Gulf of Mexico estuaries. Intensive sampling using an epibenthic sled was conducted in three Texas bays and among three potential habitat types. A long-term data set (1982 to 1997) from the National Marine Fisheries Service was also used to examine C. nebulosus habitat use patt...

متن کاملPatterns of Vertical Habitat Use by Atlantic Blue Marlin (makaira Nigricans) in the Gulf of Mexico
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 mos...
