in accordance with the present invention as shown in fig1 - 8 , there is provided a fish transfer bag 10 including a bag body 12 , a pair of handles 16 and a support band 14 for sturdy attachment of the handles 16 to the bag body 12 . as shown in fig1 , the fish transfer bag 10 comprises or consists of a bag body with a bottom 20 integrally connecting to upright side walls 22 with the corners of the bag 10 are sewn or sealed together by heat or an adhesive to eliminate the corners ( shown in broken lines ) forming angled corners 24 . the flexible corner flaps 25 formed from the sewn corners may be removed or left on the bag . the embodiment of the bag 11 shown in fig2 and 4 comprises or consists of a bag having rounded corners 26 and an open top . the embodiment of the fish transfer bag 13 shown in fig7 comprises or consists of a bag body with a bottom 20 intergrally connecting to upright side walls 22 as shown in fig7 . a preferred embodiment includes a generally rectangular bag having rounded corners or angled corners . all of the bags 10 , 11 , and 13 include a bottom side and four sides comprising or consisting of at least one polymeric film layer with interwoven mesh capable of supporting a load of water and fish up to the top of the four sides . carbon dioxide and oxygen are capable of passing through the film . the top edges of the four sides have a support band affixed to them . a pair of looped handles is fixedly attached to opposing sides of the support band . a plurality of hook and loop fasteners are attached around the periphery of the bag body parallel to and above the bottom side . the hook and loop fasteners hold a shape retaining rounded hoop in place around the bag body . moreover , a collapsible frame maybe be removably inserted into the bag to add structural support to the bag filled with water and shape the corners . removal of the frame 40 allows the bag can be stored in a small area after draining water therefrom as shown in “ fig9 . in one preferred embodiment , the webbing comprises a polypropylene core with ethylene vinyl acetate “ eva ”. a conventional adhesive can be used to join the bags at the seams . the breathable gas permeable film is comprised of multilayer of polyolefin . as shown in fig5 , the bag body 12 comprises a layer of polymeric film 40 which allows carbon dioxide to pass out of the bag and oxygen to enter into the bag . an interwoven mesh 42 is bonded to the gas permeable polymeric layer 40 for strength . moreover , the film in the present invention creates or promotes an equilibrium between the level of oxygen and carbon dioxide in the water in the bag with the oxygen and carbon dioxide level in the air surrounding the bag reducing the accumulation of carbon dioxide in water in the bag containing live fish . it is also anticipated that a breathable material such as is disclosed in us patent publication no . 20080210625 for a micro - perforated laminae and method hereby incorporated by reference , may utilize a breathable polymeric film comprising or consisting of a micro - perforated laminae includes providing a layer of polypropylene , polyethylene , polyethylene terephthalate , nylon 6 , nylon 66 , polycarbonate , polyethylene terephthalate glycol , high impact polystyrene , polyacrylonitrile - butadiene - styrene , polyacrylate , polytetrafluoroethylene , polyvinylfluoride , polyvinylchloride , chloride , polyvinylidenefluoride , cellulose acetator , polyvinylidenechloride , linear low density polyethylene or low density polyethylene , or a combination of any continuous film material . the layer of material is micro - perforated to form a plurality of micro - slits having a length of about 1 mm each spaced - apart on the thermoplastic layer at a density per square area ranging from 10 cm centers to 0 . 2 cm centers . the micro - slits define a total open orifice area that includes about 0 . 1 % to 17 . 0 % of the total surface area of the layer . in addition , the film , foil , web or sheet is preferably polypropylene ( pp ), polyethylene ( pe ), polyethylene terephthalate ( pet ), nylon 6 ( n6 ), nylon 66 ( n6 , 6 ), polycarbonate ( pc ), polyethylene terephthalate glycol ( petg ), high impact polystyrene ( hips ), polyacrylonitrile - butadiene - styrene ( abs ) or polyacrylate , polytetrafluoroethylene ( ptfe ), polyvinylfluoride ( pvf ), polyvinylchloride ( pvc ), chloride ( cpvc ), polyvinylidenefluoride ( pvdf ), polyvinylidenechloride ( pvdc ), cellulose acetate , or another suitable continuous film material . the film , foil , web or sheet preferably has a weight of between 8 g / m . sup . 2 ( 0 . 25 oz / yd . sup . 2 ) and 680 g / m . sup . 2 ( 20 . 0 oz / yd . sup . 2 ). the film , foil , web , or sheet may need a surface coating treatment to alter the surface energy . suitable surface coating / treatments include silicone , fluorocarbon , acrylic , corona treatment , flame treatment , and polyurethane . a mesh - bag , of polymeric mesh material such as polyolefin , including polyethylene , polypropylene , or the like , or plasticized polyvinyl chloride , or any suitable polymer or copolymer , is specifically adapted to allow water to circulate throughout the bag interior . any material , polymeric or coated metallic , or fabric , is within the scope of the invention and it is understood that the exact material is not critical to practice of the invention . one embodiment of the transfer bag shown in fig3 includes hook and loop fasteners 30 and 32 around the periphery of the bag body 12 . a hoop 34 , shown in fig3 is placed around the periphery of the bag and the hook and loop fasteners 30 and 32 are pressed together around the hoop 34 . the placement of the hoop around the bag forces the bag to retain the rounded shape seen in fig2 and also serves a s reinforcement to help support the weight of the water and fish . other embodiments of the fish transfer bag include a closure at the top of the bag . one closure comprises opposing hook and corresponding loop fasteners at selected positions on the inside surface of the support band 14 . another embodiment has a zip - able closure as shown in fig3 . the inside surface of one half of the support band includes a inward extending bead 22 while the inside surface of the opposite half of the support band includes a slot 24 which will removably and firmly accept the bead 22 of the first half of the closure . a simple draw string , or belt and buckle can be used to close the bag as well . another embodiment of the fish transfer bag includes a sealable air valve 28 as shown in fig1 . although not a requirement , a slight increase in air pressure over the water will enhance absorption of gases from the air when the bag is sealed for transporting the live fish . the pressure can be increased by a manual air pump or electric air pump device . as shown in fig3 , the lid 26 is hinged to an open rim 28 . the lid 26 is capable of being snapped tightly down over the rim 28 to seal the bag or can be raised to an open position to release air or water from the bag . as illustrated in fig4 , a drain 30 with a friction fit plug or threaded aperture and threaded plug may be included for draining the bag . fig1 shows a bag oxygen depletion chart from an article entitled “ keeping bass alive ”, a guidebook for angles and tournament organizers , published by espn productions , inc ./ b . a . s . s . in 2002 written by gene gillarnd and hal schramm showing depletion levels of oxygen over time at increased temperatures which is incorporated herein in its entirety . the foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom , for modification will become obvious to those skilled in the art upon reading this disclosure and may be made without departing from the spirit of the invention and scope of the appended claims . accordingly , this invention is not intended to be limited by the specific exemplification presented herein above .
