Currently, only recreational fishermen can use the process in the state on their own catch.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The harvesting method is commercially permitted in other areas in the U.S., <\/span><a href=\"https:\/\/www.rimonthly.com\/buying-ikejime\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400\">such as Rhode Island<\/span><\/a><span style=\"font-weight: 400\">, where it\u2019s establishing <\/span><a href=\"https:\/\/www.fearless-fish.com\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400\">support among businesses<\/span><\/a><span style=\"font-weight: 400\"> and consumers.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Stu Meltzer, the owner of Fearless Fish Market in Providence, said selling ike jime fish has helped him build up a strong customer base, both for wholesale buyers and visitors to his storefront. \u201cThe difference is very apparent,\u201d Meltzer said of fish prepared with ike jime. \u201cMore than a few of our customers were like, \u2018This stuff is incredible.\u2019\u201d<\/span><\/p>\n<p><iframe loading=\"lazy\" title=\"Ike Jime\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/0XY5BMp42vA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p><span style=\"font-weight: 400\">Unlike traditional handling practices that allow fish to die by passive suffocation, ike jime eliminates the stress associated with suffocation. With ike jime, the handler euthanizes the animal as quickly as possible by inserting a spike into the hindbrain of the live fish. Then, the fish is bled carefully, without injuring sellable muscle tissue, Tsui said. Though the fish\u2019s muscles will move during ike jime and its heart will temporarily still beat, the fish is brain dead by the start of the process.<\/span><\/p>\n<p><span style=\"font-weight: 400\">To delay the onset of rigor mortis, the handler runs a tool called a shinkei wire up and down the spinal column, rupturing the length of the spinal cord. When finished, the handler immediately submerges the fish into an ice slurry immediately to drop the core temperature of the fish, controlling the temperature until the fish reaches a kitchen.<\/span><\/p>\n<p><span style=\"font-weight: 400\">These steps are meant to counteract the stress behaviors of caught fish. A suffocating fish will release stress hormones, like cortisol and adrenaline, and build up lactic acid by using its muscles. Preventing the fish from going through this, as well as removing a source of bacterial infection by properly bleeding the fish, allows for both a better flavor and a significantly longer shelf life.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cRather than being on the clock for when you start to have decomposition, the natural enzymes of the fish are allowed to take over and enhance the flavor of the fish,\u201d said Meltzer, who was certified as a trainer with the Ike Jime Federation. \u201cIt\u2019s remarkable.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400\">The bill would allow individuals licensed by DNR to use ike jime for direct sale to restaurants without a separate license, creating new economic opportunities for Maryland\u2019s independent seafood producers. Tsui said ike jime could allow a wider scope of Maryland seafood to reach price points that Maryland producers may never have had access to in the past.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cRestauranteurs around the region, and especially those with coveted Michelin stars, are eagerly awaiting the opportunity to source this level of quality locally too,\u201d Tsui said.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Maryland DNR Secretary Josh Kurtz said using ike jime could help increase the value of fish caught in the Chesapeake Bay and other Maryland waters.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cIf we&#8217;re taking something out of the ecosystem, we want to ensure that it has maximum value\u2014this process will allow us to receive maximum value for the species,\u201d Secretary Kurtz said. \u201cThat will allow us to work with our watermen, with our anglers to ensure that we&#8217;re just maximizing all of the benefits of this species whenever we pull them out of the water.\u201d<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Chesapeake Bay Legacy Act would allow interested processors to use the technique in Maryland A traditional Japanese method for processing fish may be expanding in Maryland.
