I Googled it. "An otter trawl consists of a large fish net that is dragged behind a research vessel along the sea bottom or the pelagic zone. The otter trawl is mainly used to catch roundfish living above the sea bottom such as whiting and cod."
Actually, an otter trawl is not just used by research vessels. An otter trawl is a net, dragged behind a vessel, with the mouth of the net held open by the action of two "otter doors" (often just called "doors", or "otters"). The otter doors are wooden or metal vanes, asymmetrically attached, so that they act kind of like "kites" as the are dragged behind the vessel. They pull the mouth of the net open laterally, while a float line on top and a chain line on the bottom keep it open vertically. Research versions of otter trawls are as small as 10 meters wide and have doors (usually wooden with metal skids on the bottom) about a half a meter or so by 25-30 cm or so. Large commercial vessel can drag MUCH larger otter trawls with doors (made of plate steel) several meters in length and weighing several tonnes. Otter trawls as they were traditionally constructed are often VERY destructive to the bottom habitat, cutting down anything in their path and essentially turning over the top layers of sediment up to a half a meter or so below the original surface. Nowadays, otter trawls often (but not always) have rollers on the chain line, allowing the net to "skip" over the bottom, thus doing somewhat less damage.
Yes she did. Hawaii Road Race Assn. In her last season she wore the number 6 plate having been the top points winner in the 600cc class (Numbers 1 thru 5 being reserved for the open class, 750cc and up. (Number 1 was a guy on a GSXR1000) To win a single digit number plate is a significant accomplishment. Even better - she was the only woman on the track. So proud of her.
