Modelling Diurnal Variation In Bottom Trawl Catches

1999
No abstracts are to be cited without prior reference to the author.Diurnal variability in bottom trawl survey catches may influence the quality of the survey results when not taken properly into account. This is especially the case if diurnal effects vary substantially from year to year.

Dynamic Analysis of Trawl Doors Applied in Bottom Trawls to Catch Shrimp

This work deals with the dynamic analysis of a new design of trawl doors. The model is constrained to steady towing conditions with velocity constant, flat seabed and gear symmetry. The Ordinary Differential Equations (ODE) of the system includes the effects of the warp and the ropes in terms of external forces. In the mathematical model the influences

Bottom trawl teuthofauna of the Aegean Sea

1997
The bathymetric distribution and catch composition of cephalopods in the Aegean Sea were investigated. For this purpose a total of 292 bottom trawls were carried out seasonally during 1991 and 1992. Sampling depths ranged between 20 and 500 m. A total of 30 species were recorded, with Sepiola intermedia and Histioteuthis bonnellii being found in the ...
