Sound Production by Atlantic Cod during Spawning
Transactions of the American Fisheries Society - Tập 135 Số 2 - Trang 529-538 - 2006
AbstractUsing captive groups of Atlantic cod Gadus morhua from two Northwest
Atlantic populations (western Scotian Shelf and southern Gulf of St. Lawrence),
we quantified the temporal patterns and behavioral contexts of sound production
during the spawning season. We found that sound production occurs most
frequently during the peak of the spawning period, particularly after the onset
of darkness....
A Revised Alverson and Carney Model for Estimating the Instantaneous Rate of Natural Mortality
Transactions of the American Fisheries Society - Tập 135 Số 3 - Trang 620-633 - 2006
AbstractThe Alverson and Carney (AC) model for estimating the instantaneous rate
of natural mortality (M) was reformulated to include β andt0parameters. The
revised Zhang and Megrey (ZM) model could be used for the estimation ofMinstead
of the AC model since von Bertalanffy and allometric growth parameters are
readily available for most exploited fish stocks. It was determined from the new
formula...
Habitat‐Specific Reproductive Potential of Red Snapper: A Comparison of Artificial and Natural Reefs in the Western Gulf of Mexico
Transactions of the American Fisheries Society - Tập 147 Số 6 - Trang 1030-1041 - 2018
AbstractEnergy exploration in the Gulf of Mexico (hereafter, Gulf) has resulted
in the addition of numerous oil and gas production platforms that create
structurally complex habitat in an area otherwise dominated by barren mud/sand
bottom. How these artificial structures affect fish populations is largely
unknown, and there is ongoing debate regarding their value as surrogate habitats
for ecologic...
Diel Feeding Patterns of Red Snapper on Artificial Reefs in the North‐Central Gulf of Mexico
Transactions of the American Fisheries Society - Tập 132 Số 6 - Trang 1186-1193 - 2003
AbstractDiets of red snapper Lutjanus campechanus were compared among four diel
feeding periods (dawn, day, dusk, and night) and among three standard length
size‐classes: small (200–299 mm), medium (300–399 mm), and large (400–499 mm).
Fish were collected from August through October 2000 in the north‐central Gulf
of Mexico. A total of 432 stomachs were examined, of which 164 (37%) contained
prey. ...
Fine‐Scale Movements and Home Ranges of Red Snapper around Artificial Reefs in the Northern Gulf of Mexico
Transactions of the American Fisheries Society - Tập 143 Số 4 - Trang 988-998 - 2014
AbstractRed Snapper Lutjanus campechanus are generally associated with
artificial reef habitats in the northern Gulf of Mexico, but whether this
association results in fish production is still controversial. Information on
fine‐scale habitat use patterns would be helpful in evaluating this. Little is
known about the fine‐scale movement patterns of Red Snapper around artificial
reefs. The present s...
Long‐Term Residence of Red Snapper on Artificial Reefs in the Northeastern Gulf of Mexico
Transactions of the American Fisheries Society - Tập 134 Số 2 - Trang 315-325 - 2005
AbstractRed snapper Lutjanus campechanus (N = 54) were tagged and tracked on 12
artificial reefs in the northeastern Gulf of Mexico. Fish were surgically
implanted with ultrasonic transmitters and monitored with Vemco remote receivers
and Sonotronics surface receivers from August 2000 to 2004. Four fish were
manually tracked from the surface overnight, and their positions were recorded
every hour ...
Red Snapper Reproductive Biology in the Southern Gulf of Mexico
Transactions of the American Fisheries Society - Tập 139 Số 4 - Trang 957-968 - 2010
AbstractSex ratio, size at maturity, reproductive periodicity, ovarian
development pattern, and spawning ground data for red snapper Lutjanus
campechanus from the southern Gulf of Mexico were analyzed to understand this
species' reproductive biology throughout its geographical distribution. Red
snapper were sampled in 1999 and 2000 from commercial fishery catches taken on
Campeche Bank at depths r...
A Comparison of Size Structure, Age, and Growth of Red Snapper from Artificial and Natural Habitats in the Western Gulf of Mexico
Transactions of the American Fisheries Society - Tập 146 Số 4 - Trang 762-777 - 2017
AbstractRed SnapperLutjanus campechanussupport economically important fisheries
in the Gulf of Mexico (GOM) and have been classified as overfished since the
first stock assessment was conducted in 1988. Although the stock is now showing
signs of recovery, management could benefit from a better understanding of
regional or even habitat‐level differences in stock demographics, as these
dynamics ulti...
Distribution and Age Composition of Red Snapper across the Inner Continental Shelf of the North‐Central Gulf of Mexico
Transactions of the American Fisheries Society - Tập 147 Số 5 - Trang 791-805 - 2018
AbstractThe Red Snapper Lutjanus campechanus is an economically and ecologically
important species in the northern Gulf of Mexico, where it often dominates the
reef fish community in shallow to mid water depths along the continental shelf.
The affinity of Red Snapper for artificial and natural reefs is well
established; however, this affinity appears to vary with age. We used a
multigear survey th...
Mislabeling of Two Commercial North American Hake Species Suggests Underreported Exploitation of Offshore Hake
Transactions of the American Fisheries Society - Tập 138 Số 4 - Trang 790-796 - 2009
AbstractMislabeling of North American merlucciid hakes in stock surveys and
commercial market samples was detected by employing nuclear 5S ribosomal DNA
(rDNA) and mitochondrial cytochrome b variation as molecular markers. Results
showed that offshore hake Merluccius albidus is sold in European markets but is
labeled as the morphologically similar silver hake M. bilinearis, which is the
target spe...
