Investigating gear and seasonal effects in experimental trawl surveys: The case of Galeus melastomus Rafinesque, 1810 (Chondrichthyes, Scyliorhinidae) in the South of Sicily (Central Mediterranean)

Egyptian Journal of Aquatic Research, 2017
Mediterranean young-fish oriented experimental bottom trawl surveys represent a precious source of information on both past and current standing stocks and their life history traits and exploitation state.

Horizontal distribution and overlap of planktivorous fish stocks in the Norwegian Sea during summers 1995–2006 [PDF]

, 2012
The Norwegian Sea harbours several large pelagic fish stocks, which use the area for feeding during the summer. The period 1995–2006 had some of the highest biomass of pelagic fish feeding in the Norwegian Sea on record.

Some updates to the method for calculation of parameters of bottom trawl system

Известия ТИНРО, 2016
The method for calculation of geometric parameters of trawl system proposed by F.I. Baranov is analyzed. The calculation includes evaluation of spacer force and drag for all elements of trawl system and solution of transcendental equation to find a ...

Efficiency of the bottom trawl used for the Mediterranean International Trawl Survey (MEDITS) [PDF]

, 1999
The aim of the work presented in this paper was to assess the relative efficiency of the GOC 73 sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) compared with that of a typical Italian commercial trawl. The latter was chosen because it is commonly used by fishermen in the central Adriatic, where the experiment was

Geographical patterns of seabird attendance to a research trawler along the Iberian Mediterranean coast

Scientia Marina, 2003
The attendance of seabirds to a research trawler along the Mediterranean coast of the Iberian Peninsula was monitored during six demersal surveys (MEDITS project). Cruises were performed in late spring during the period 1994-1999.

Prospects for the pink salmon fishery in the Russian waters of the Bering and Okhotsk Seas in 2023 based on analysis of trawl surveys of the juveniles aboard RV TINRO and RV Professor Kaganovsky in autumn 2022

Известия ТИНРО, 2023
Modern technique of counting pink salmon juveniles in trawl surveys by two research vessels simultaneously makes it possible to cover the surveyed area in a short time that excludes repeated counts of actively migrating fish at adjacent transects.

Improvement of methods for estimation of catchability for trawl survey systems with use of hydroacoustic means (on example of walleye pollock in the Okhotsk Sea)

Известия ТИНРО, 2015
In commercial fishery, catching properties of fishing gears are developed mostly for effective catch of fish, rather than for precise measurement of fish distribution density in water, so a problem of catchability exists and this parameter should be ...
