摘要：
An apparatus for harvesting aquatic animals has a cod end portion and an elongate lengthener portion. The cod end portion has an open leading end and a closed trailing end and side wall(s), the side wall(s) and the trailing end being substantially impervious to water. The elongate lengthener portion has a leading end, a trailing end, and side wall(s), at least a major part of the side wall(s) comprising a material substantially impervious to water. The trailing end of the lengthener portion is operatively connected to the leading end of the cod end portion. The elongate lengthener portion comprises a plurality of escapements through which water can pass from an interior to an exterior of the apparatus to cause a general reduction in the water flow rate inside the apparatus when the apparatus is submerged in a body of water and there is water flow relative to the apparatus.
