Photographic observations on reactions of fish ahead of otter trawls
Using twin-rigged otter trawls
, the fishery runs year round and is utilized by just two companies under 20 licenses.
balloti are caught using otter trawls
, rigged in either triple- or quad-gear configuration, with vessels ranging in size between 9 m and 22 m.
Two general types of otter trawls
were experimented with during the survey: the Atlantic type had two seams and was low-opening (FWS, 1942: Fig.
From 1992-97, juvenile fish were collected using otter trawls
and bag seines in the Rio Grande from its confluence with the Gulf of Mexico to 48.
The use of otter trawls
as a means surveying shelf and slope depth communities has been a common element of marine monitoring programs in the SCB since the 1970s.
1970) collected three times as many blue catfish as channel catfish in otter trawls
in Maurepas and Turner and Savoie (1976) collected 373 blue catfish and no channel catfish in Lakes Pontchartrain and Maurepas.
The majority of spiny dogfish landed during the 1970s and 1980s (mean: 4500 t [SD 1280]) were indirectly caught by otter trawls
(OT) as bycatch in groundfish and other fisheries (Rago and Sosebee, 2009).
1994), using a skimmer trawl designed by a Louisiana commercial shrimp industry member, compared catch rates between skimmer and otter trawls
in the inshore waters of North Carolina.
Demersal otter trawls
used in both commercial fisheries and resource assessments lack a rigid frame; instead, sheer on the trawl doors and various operational factors (e.
Like the majority of otter trawls
, prawn trawls typically are poorly selective fishing gears, and in addition to the targeted species they also catch and retain large quantities of nontarget species (termed by-catch), which often comprises a diverse assemblage of small fish, crustaceans, and cephalopods (for reviews see Andrew and Pepperell, 1992; Kennelly, 1995).
Another sampling program was conducted with small otter trawls
between 1988-90 and 1996-2009 at a variety of stations and habitats located throughout the Mullica River--Great Bay--Inner Continental Shelf corridor (Table 1).
