Areas of active, if subdued, hydrocarbon seeps are notably devoid of large sessile invertebrates. A fluffy gray biofilm coats the underlying rock, dotted with small white patches of the chemo-seep-associated bacteria Beggatoia.

Reaching a length of 1.5 m, the grouper-like Wreckfish (Polyprion americanus) is an apex predator living on deep reefs worldwide, and probably spawning on western Atlantic Lophelia coral reefs.

Sculling along in triggerfish-fashion, the Tinselfish (Grammicolepis brachiusculus) hovers as brown dead Lophelia coral is collected, along with a pencil urchin (Cidaris rugosa) and patches of blue desmacollid sponge. With its tubular mouth permanently frozen open, the Tinselfish vacuums up small crustaceans living on Lophelia.

Small sprigs of glass coral are snipped off by the submersible's manipulator and transferred to a multi-chambered sampler for bacterial and genetic analyses. Attracted by the disturbance, a large Conger Eel (Conger oceanicus) then a Snowy Grouper (Epinephelus niveatus), investigates the scene.

Temporal and spatial relationships of Yellowfin Tuna to deepwater petroleum platforms in the northern Gulf of Mexico
In 2006–2007, 110 Yellowfin Tuna Thunnus albacares were tagged with acoustic transmitters near deepwater oil platforms and one drillship in the northern Gulf of Mexico off the Mississippi River delta to determine the extent to which platforms act as fish aggregating devices (FADs). Vemco acoustic receivers were installed on six deepwater platforms to detect the presence of tagged individuals. FiveAuthorsMelissa E. Price, Michael T. Randall, Kenneth J. Sulak, Randy E.

The goal of a day-long symposium on March 3, 2015, Sturgeon in the Sacramento–San Joaquin Watershed: New Insights to Support Conservation and Management, was to present new information about the physiology, behavior, and ecology of the green (Acipenser medirostris) and white sturgeon (Acipenser transmontanus) to help guide enhanced management and conservation efforts within the Sacramento–San JoaqAuthorsA Peter Klimley, Eric D Chapman, J.

Thomas, David Woodbury, Megan T. WymanStatus of scientific knowledge of North American sturgeon
Sturgeon and paddlefish were historically the dominant large fishes in all major Northern American Rivers. All ten species have been affected the past 150 years from anthropogenic stressors such that they are considered imperiled by various jurisdictions. Status papers have been presented for each species as part of a special publication on North American Acipenseriformes. The objective of this paAuthorsTim J. Haxton, Kenneth J. Sulak, L.

Detailed observations in the deep sea can reveal previously unknown behaviour, species interactions and fine-scale habitat heterogeneity. Here, the first in situ images of the black coral Schizopathes sp. (Anthozoa: Antipatharia) in the deep western Indian Ocean have been obtained from remotely operated vehicle video footage and time-lapse photography. In these images, there appears to be an assocAuthorsAndrew R. Gates, Kirsty Morris, Daniel O.B. Jones, Kenneth J.

The Gulf Sturgeon, Acipenser oxyrinchus desotoi, is an anadromous species of Acipenseridae and native to North America. It currently inhabits and spawns in the upper reaches of seven natal rivers along the northern coast of the Gulf of Mexico from the Suwannee River, Florida, to the Pearl River, Louisiana, during spring to autumn. Next to the Alligator Gar (Atractosteus spatula), the Gulf SturgeonAuthorsKenneth J. Sulak, F Parauka, W. Todd Slack, T Ruth, Michael T. Randall, K Luke, M. F Mette, M.

Mid-February in the Gulf of Mexico and a timeless ritual is about to repeat itself for perhaps the millionth time. Some mysterious signal, possibly increasing day length, flips an internal switch, feeding stops, and the homeward migration begins for the Gulf Sturgeon (Acipenser oxyrinchus desotoi).

SulakSurvival of hatchery Gulf sturgeon (Acipenser oxyrinchus desotoi Mitchill, 1815) in the Suwannee River, Florida: a 19-year evaluation
An experimental release of 1192 hatchery-reared, individually PIT tagged, 220 days old (296–337 mm TL) Gulf sturgeon, Acipenser oxyrinchus desotoi, was undertaken in 1992 in the Suwannee River, Florida. The original objectives of the 1992 release experiment were to: (1) evaluate survival rate of cultured Gulf sturgeon in the wild vs survival rate of their wild 1992 cohort counterparts, (2) determiAuthorsKenneth J.

Stable 13C, 15N, and 34S isotopes were analyzed to define the feeding habitats of Acipenser oxyrinchus desotoi in the Suwannee and Yellow River populations. For the majority (93.9%) of Suwannee subadults and adults, 13C and 34S signatures indicate use of nearshore marine waters as primary winter feeding habitat, probably due to the limiting size of the Suwannee Sound estuary.
