The article highlights the problems of managing trawl fishing, increasing operation efficiency and reducing influence human factor. There has been considered using 
 a neural network in combination with mathematical model BigData technologies for predictive modeling process automatic control fishing order to increase its (to reduce energy labor costs, productivity). Advantages proposed app...

Identification of different species of oceanic and neritic squids in Iranian waters of Oman Sea was carried out from December 1996 to February 1997. The trawl surveys were conducted during a 12-months period. Fishing was also undertaken by Mid-water and bottom trawl for species confirmation purposes in deep (200-350m) and shallow (0-100m) waters to collect enough specimens that could be used fo...

The red shrimp, Aristeus antennatus (Risso, 1816), is one of the most important resources for the bottom-trawl fleets in the northwestern Mediterranean, in terms of both landings and economic value (Demestre and Lleonart, 1993; Demestre and Martin, 1993; Maynou et al., 2006). One of the ports obtaining the highest yields in the area is that of Blanes (Irazola et al., 1996; Bas, SCIENTIA MARINA ...

Some large Saurenchelys specimens collected from Daxi, Yilan, NE Taiwan, and Da Nang, Vietnam, by bottom trawl at depths of 100-200 m, are described as Saurenchelys gigas new species. They differ from all known adult Saurenchelys species by predorsal length 40.9-46.8, head length 36.8-39.3in % of preanal length, 38-40 preanal vertebrae, 63-70 precaudal vertebrae, 38-42 preanal lateral-line pore...

The Northwest Fisheries Science Center (NWFSC) has produced reports documenting total fishing mortality for groundfish for the years 2004-2006, which are available on the NWFSC’s website (Hastie 2006, Hastie and Bellman 2006, 2007). A central element of these analyses is the estimation of discard occurring in the non-hake groundfish bottom trawl fishery. This estimation process incorporates dat...

Predictive modeling (PM) of the trawl system (TS) is a complex, interdisciplinary and cognitive representation TS links. vehicle predicts its operational parameters in various conditions (transition, etching warriors, trawling, hauling other processes). It also possible to process data experiments numerical simulations on basis PM together, which not compatible with mathematical physical simula...

Abstract. Bottom trawling in shelf seas can occur more than 10 times per year for a given location. This affects the benthic metabolism, through mortality of macrofauna, resuspension organic matter from sediment, and alterations physical sediment structure. However, impacts on carbon mineralization associated processes are not well known. Using modelling approach, effects increasing frequencies...

Despite an ever-expanding database of sequenced mammalian genomes to be mined for clues, the emergence of the unique human brain remains an evolutionary enigma. In their new study, trawl the human genome and those of other mammals in search of short conserved DNA elements that show extremely rapid evolution only in humans. As they report in a recent issue of Nature, their scan yielded a gene fo...
