Italian to English Tech/Engineering Fisheries

This is from a report on the fishing industry (and in particular clam harvesting) in Northern Italy.

Ciò ha portato anche alla proliferazione di una serie di strumenti di pesca e raccolta (turbosoffiante, vibrante, ‘rusca’), alcuni fortemente impattanti sull’ecosistema.

This link describes what 'rusca' is - http://icesjms.oxfordjournals.org/content/61/1/43.full.pdf

I therefore assume that it shouldn't be translated, but I thought I would check that someone doesn't knowof a suitable English equivalent.

Thanks very much in advance,
Ian
