Modeling the characteristics of a bottom trawl

Trudy VNIRO
The purpose of the work is to create software for calculating the structural, geometric and strength characteristics of mesh bottom trawl structures, intended for modeling technological and hydrodynamic processes of trawl structures.Methods used: The software “Calculation of the structural, technological and power characteristics of a bottom mesh trawl”

Phylogeography of the widely distributed John Dory (Zeus faber, Actinopterygii: Zeiformes) reaffirms the prevalence of at least two deeply divergent clades

Journal of Fish Biology, EarlyView.
Abstract The John Dory Zeus faber is a commercially exploited demersal fish species with a known distribution ranging from the Northeast Atlantic to parts of the Indian and Pacific oceans. A previous genetic survey using cytochrome c oxidase subunit I (COI) DNA barcodes suggested the presence of two geographically segregated taxonomic units within Z ...

Temporal Changes in a Tropical Nekton Assemblage and Performance of a Prawn Selective Gear [PDF]

, 1995
The temporal variation of components of a moderately diverse (H=1.46) tropical estuarine fish assemblage (long. 146°30'E, lat. 8°45'S) was directed by salinities that had been determined by local oceanographic and probably topographic conditions.

Changes in the juvenile fish assemblage of a Mediterranean shallow Posidonia oceanica seagrass nursery area after half a century [PDF]

, 2019
The within-year dynamics of the juvenile fish community in a shallow seagrass-dominated nursery habitat (Posidonia oceanica) in a Mediterranean bay were compared between two surveys separated by 50 years (1960 and 2012-2013).

Community science datasets identify the spatial occurrence and hotspots of flapper skate (Dipturus intermedius)

Journal of Fish Biology, EarlyView.
Abstract The flapper skate, Dipturus intermedius (Parnell, 1837), is a large‐bodied, slow‐growing and late‐maturing, Critically Endangered elasmobranch with a constrained population distribution. Here, we use two longitudinal community science datasets to investigate the occurrence of flapper skates in Irish waters. The two datasets are as follows: the

Modelling potential impacts of bottom trawl fisheries on soft sediment biogeochemistry in the North Sea†

Geochemical Transactions, 2001
Bottom trawling causes physical disturbance to sediments particularly in shelf areas. The disturbance due to trawling is most significant in deeper areas with softer sediments where levels of natural disturbance due to wave and tidal action are low.

Observations of the 1992 U.S. Pelagic Pair Trawl Fishery in the Northwest Atlantic [PDF]

, 1994
Pelagic pair trawling for tuna, Thunnus spp., and swordfish, Xiphias gladius, was introduced in U.S. Northwest Atlantic waters in 1991. During autumn (October-November) of 1992 under the authority oft he Federal Atlantic Swordfish Regulations, the ...

On the occurrence of the snakefish Trachinocephalus myops (Aulopiformes: Synodontidae) in the Azores archipelago

Journal of Fish Biology, EarlyView.
Abstract The snakefish Trachinocephalus myops is an Atlantic species distributed in tropical and temperate coastal waters on sandy substrates. This study reports the validated record of an adult T. myops in the Azores archipelago caught by a fisherman at Faial Island.
