Sentence examples for trawl efficiency from inspiring English sources

The results of the study indicate that footrope contact, and therefore trawl efficiency, is not independent of trawl speed.

Trawls energy efficiency is greatly affected by the drag, as well as by the swept area regarding pelagic trawls and by the swept width for bottom ones.

As with other modern commercial fishing methods like factory trawling, this efficiency is not all to the good, as the decline of many fish stocks around the world testifies.

An avenue for relieving the situation is to improve the energy efficiency of trawling by raising the productivity of fishing per litre of fuel consumed.

Such a methodology was used in two cases: which show a 43% increase in energy efficiency regarding the pelagic trawl case and 27% for the bottom trawl one.

The results reaffirm that because otter boards contribute towards a large proportion of total system drag (estimated here at up to ∼56%), their appropriate configuration is essential to maximise the fuel efficiency of penaeid-trawl systems.

However, detailed analyses of diversity patterns of epibenthos were hampered by the still variable trawling distance per haul, and the low and partly unknown catch efficiency of the beam-trawl.

The present work analyzed different possibilities to mitigate the impact of gears on the seabed and to increase the efficiency of the bottom trawl fishery of the Western Mediterranean.

This study reports on energy efficiency optimization regarding bottom trawls.

The results support simple, retrospectively fitted alterations to existing penaeid-trawl bodies to improve selection and efficiency.

Prior to starting the experiment, a codend cover (18-mm diamond-shaped mesh) was tested and demonstrated to have no effect on the catching efficiency of a typical estuarine trawl, thereby validating its use for assessing size selectivity.
