摘要：
An apparatus 1 for harvesting aquatic animals, comprising a cod end portion 2 having an open leading end 2a and a closed trailing end 2b and one or more side walls 2c between the leading end 2a and the trailing end 2b, where the side wall(s) 2c comprise(s) a flexible membrane and wherein the side wall(s) 2c and the trailing end 2b are substantially impervious to water, and an elongate lengthener portion 3 having a leading end, a trailing end, and one or more side wall(s) between the leading end and the trailing end, wherein at least a major part of the side wall(s) comprise(s) a flexible membrane that is substantially impervious to water, and where 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 fish that are smaller than a certain size and water can pass from an interior of the apparatus to an exterior of the apparatus to cause a general reduction in the water flow rate inside the apparatus from the leading end of the elongate lengthener portion toward the trailing end of the cod end portion when the apparatus is submerged in a body of water and there is water flow relative to the apparatus
