Abstract: A method for extracting aquatic animals from an apparatus (102) containing aquatic animals. The apparatus has a body with an open end (102a), a substantially closed end (102b), and one or more side walls (102c) between the open end and the substantially closed end. At least a major portion of the side wall(s) are in the form of a flexible membrane, and at least a major portion of the side wall(s) and the substantially closed end are substantially impervious to water. The method involves arranging the apparatus (102) with an open end (102a) of the apparatus positioned higher than a substantially closed end (102b) of the apparatus, introducing a flow of liquid into an interior region of the apparatus proximal the substantially closed end, and using the introduced flow of liquid to transport aquatic animals contained in the apparatus, out of the open end (102a) of the apparatus.

Abstract: 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.
