From:PLoS ONE (Vol. 8, Issue 5) Peer-ReviewedAuthor(s): Finlay N. Thompson *, Edward R. Abraham, Katrin Berkenbusch Introduction Direct interactions between fisheries and marine mammals frequently occur when fishing operations overlap with the distribution...

From:Fishery Bulletin (Vol. 116, Issue 1) Peer-ReviewedBottom trawl surveys need constant catchability over time to produce estimates of relative abundance that are most informative for stock assessment modeling. However, environmental conditions during surveys can...
-
From:Fishery Bulletin (Vol. 108, Issue 3) Peer-ReviewedAbstract--The time series of abundance indices for many groundfish populations, as determined from trawl surveys, are often imprecise and short, causing stock assessment estimates of abundance to be imprecise. To...

From:PLoS ONE (Vol. 15, Issue 1) Peer-ReviewedWe used three complementary methods to assess the diet of two insectivorous bat species: one an obligate aerial hunter, Miniopterus natalensis, and the other Myotis tricolor whose morphology and taxonomic affiliation to...
-
From:PLoS ONE (Vol. 5, Issue 9) Peer-ReviewedBackground Environmental impacts of human activities on the deep seafloor are of increasing concern. While activities within waters shallower than 200 m have been the focus of previous assessments of anthropogenic...

From:PLoS ONE (Vol. 12, Issue 7) Peer-ReviewedIn sediment cores spanning ~500 years of history in the Gulf of Trieste, down-core changes in molluscan community structure are characterized by marked shifts in species and functional composition. Between the 16.sup.th...

From:Marine Fisheries Review (Vol. 72, Issue 3) Peer-ReviewedSatellite telemetry is a common tool for examining sea turtle movements, and many research programs have successfully tracked adults. Relatively short satellite track durations recorded for juvenile Kemp's ridley sea...

Review of the California trawl fishery for Pacific ocean shrimp, Pandalus jordani, from 1992 to 2007
The commercial bottom trawl fishery for Pacific ocean shrimp, Pandalus jordani, or pink shrimp, operates mostly off the west coast of the contiguous United States. The California portion of the fishery has not been... -
From:International Journal of Distributed Sensor Networks (Vol. 2014) Peer-Reviewed
Real-time 3D simulation for the trawl fishing gear based on parallel processing of sonar sensor data
A huge and a complex internal computation is required to visualize the underwater geometry of a fishing gear, because each particle of the gear should be calculated with consideration of several force vectors, such as... -
From:PLoS ONE (Vol. 11, Issue 8) Peer-ReviewedThe aim of this study was to provide practitioners working with trawl selectivity with general and easily understandable guidelines regarding the fish sampling effort necessary during sea trials. In particular, we...
-
From:PLoS ONE (Vol. 6, Issue 3) Peer-ReviewedFisheries have major impacts on seabirds, both by changing food availability and by causing direct mortality of birds during trawling and longline setting. However, little is known about the nature and the...
-
From:The American Midland Naturalist (Vol. 185, Issue 2) Peer-ReviewedLike many large rivers in modern industrialized regions, the Ohio River mainstem is a heavily modified riverine habitat comprised of various reservoir-dam series and shaped channels, rather than a free-flowing system....
-
From:Fishery Bulletin (Vol. 120, Issue 1) Peer-ReviewedThe role of deepwater corals and sponges in the life history of fish species is generally unknown for the larval stage. In 2017, we deployed an autonomous plankton pump into deepwater coral habitat (depths: >50 m) to...
-
From:Marine Resource Economics (Vol. 9, Issue 3) Peer-ReviewedThe proposed regulation to reduce bycatch and discarding offinfish in the southeastern region is a gear modification that excludes finfish from shrimp trawls. This regulation is analyzed using a simple theoretical model...
-
From:Fishery Bulletin (Vol. 106, Issue 4) Peer-ReviewedAbstract--Trawling and dredging on Georges Bank (northwest Atlantic Ocean) have altered the cover of colonial epifauna, as surveyed through in situ photography. A total of 454 photographs were analyzed from areas with...
-
From:Brazilian Journal of Biology (Vol. 71, Issue 4) Peer-ReviewedThis study examines the qualitative and quantitative aspects of fishery landings at the hypereutrophic Barra Bonita reservoir, Brazil. Data were collected each month (July/2004-June/2006) at three localities and the...
-
From:PLoS ONE (Vol. 16, Issue 1) Peer-ReviewedA new bycatch reduction device, termed "Excluder", is presented as an alternative to a traditional rigid sorting grid, mandatory in the small-meshed Norway Pout (Trisopterus esmarkii) trawl fishery in the North Sea. The...
-
From:PLoS ONE (Vol. 8, Issue 12) Peer-ReviewedUnited Nations General Assembly Resolution 61/105 on sustainable fisheries (UNGA 2007) establishes three difficult questions for participants in high-seas bottom fisheries to answer: 1) Where are vulnerable marine...
-
From:PLoS ONE (Vol. 8, Issue 8) Peer-ReviewedThis study describes the impact of the first passage of two types of bottom-towed fishing gear on rare protected shellfish-reefs formed by the horse mussel Modiolus modiolus (L.). One of the study sites was trawled and...
-
From:PLoS ONE (Vol. 10, Issue 3) Peer-ReviewedFor prawn trawling systems, drag reduction is a high priority as the trawling process is energy intensive. Large benefits have occurred through the use of multiple-net rigs and thin twine in the netting. An additional...
