Qalong sehlooho sena se hlahile CDN

Calvert Marine Museum e Solomons, Maryland e tla be e ruta batho ba eang musiamong ka Lionfish e hlaselang ka kotsi e sokelang metsi a Caribbean le litsamaiso tsa mafika. Lionfish li ntle ebile ha li tloaelehe, empa joalo ka mofuta o sa tloaelehang oa Atlantic, ho ata ha tsona ka potlako ho ka baka mathata a maholo a tikoloho le moruo. Ka li-spikes tse telele tse chefo le chebahalo e khanyang, Lionfish e mebala e khanyang 'me e na le balateli ba makatsang ba ho hlahisa li-spikes tse chefo tse etsang hore lionfish e bonahale habonolo. Litho tsa mofuta oa Pterois, bo-rasaense ba fumane mefuta e 10 e fapaneng ea lionfish.

E hlaha Pacific Boroa le Indian Oceans Lionfish e hola lipakeng tsa lisenthimithara tse peli ho isa ho tse 15 ka bolelele. Ke libatana tse mabifi tsa litlhapi tse nyenyane, li-shrimp, makhala le liphoofolo tse ling tse nyenyane tsa leoatleng, tse lulang metsing a haufi le mafika a likorale, marako a majoe le matangoana. Lionfish e phela ka karolelano pakeng tsa lilemo tse hlano le 15 'me e ka ikatisa khoeli le khoeli ka mor'a selemo sa eona sa pele. Leha ho loma ha lionfish ho ka ba bohloko haholo, ho baka bothata ba ho hema, ho nyekeloa ke pelo le ho hlatsa, ha se hangata ho bolaeang batho. Tsa bona maqeba e na le motsoako oa protheine, chefo ea neuromuscular le acetylcholine, neurotransmitter.

Kaha ha e hlahe Leoatleng la Atlantic, mefuta e ’meli ea lionfish—lionfish e khubelu le lionfish e tloaelehileng—e atlehile Caribbean le haufi le Lebōpo le ka Bochabela la United States hoo hona joale e seng e nkoa e le mefuta e hlaselang. Bafuputsi ba bangata ba lumela hore lionfish qalong e ile ea kena metsing a haufi le lebōpo la Florida ka bo-1980. Leholiotsoana Andrew, ka 1992, le ile la senya metsi a leoatle Biscayne Bay, la lokolla lionfish tse tšeletseng metsing a bulehileng. Lionfish li fumanoe ho ea fihla leboea ho North Carolina le ho ea fihla boroa ho Venezuela, 'me mefuta ea tsona e bonahala e ntse e eketseha. Ho bonahala eka phetoho ea boemo ba leholimo le eona e ka 'na ea e-ba le karolo.

Lionfish li na le libatana tse seng kae tse tsejoang tsa tlhaho, e leng le leng la mabaka a mantlha a entseng hore li fetohe bothata bo boholo libakeng tse ling tsa Lebopo le ka Bochabela le Caribbean. Calvert Marine Museums e na le tšepo ea ho ruta baeti ka sebata sena se hlaselang se sokelang litlhapi tse phelang metsing a rona a futhumetseng, le hore na metsi ao a futhumetseng a thusa Lionfish joang hore e atlehe.

David Moyer, Mohlokomeli oa Biology ea Estuarine ho hlalosa: Setsi sa pokello ea nalane ea Calvert ho Solomons, MD.

“Lionfish li hlasela Leoatle la Atlantic le ka Bophirimela. Nakong ea lehlabula, li fihla ka leboea ho New York, ho hlakile hore li tsamaisoa ho pholletsa le sebaka sa leoatle sa Maryland. Ha phetoho ea maemo a leholimo e tlisa mocheso o futhumetseng oa metsi a leoatle sebakeng sa rona, 'me ha bophahamo ba leoatle bo ntse bo tsoela pele ho kena metsing a sa tebang a lebopong la Maryland, monyetla oa hore lionfish o thehoe ka ho sa feleng metsing a rona oa eketseha, "Moyer o ngotse lengolo-tsoibila la morao tjena.

Baahi ba lionfish libakeng tsena ba eketseha ka potlako. The Litsi tsa Naha tsa Saense ea Leoatle la Leoatle (NCCOS) e hakanya hore metsing a mang bongata ba lionfish bo fetile mefuta e mengata ea tlhaho. Libakeng tse 'maloa tse chesang ho na le lionfish tse fetang 1,000 ka acre.

Bafuputsi ha ba tsebe hantle hore na palo e ntseng e eketseha ea lionfish e tla ama palo ea litlhapi tsa matsoalloa le ho tšoasa litlhapi tsa khoebo joang. Leha ho le joalo, lia tseba hore mefuta e meng ea lintho tse phelang linaheng tse ling e ka ba le phello e mpe tikolohong ea tlhaho le moruong oa libaka oa ho tšoasa litlhapi. Ho boetse hoa tsebahala hore lionfish e ja snapper le grouper, mefuta e 'meli ea bohlokoa khoebong.

Ho latela National Oceanic and Atmospheric Administration (NOAA), lionfish e ka baka tšenyo e mpe ho baahi ba mafika ka ho sitisa botsitso ba tikoloho e itseng. Joaloka libatana tse ka holimo-limo, lionfish e ka fokotsa palo ea liphofu le ho qothisana lehlokoa le libatana tsa mafika, ka mor'a moo tsa nka karolo ea tsona.

Bafuputsi ba tlaleha hore ho hlahisoa ha lionfish libakeng tse ling ho fokotsa lebelo la ho phela ha mefuta ea litlhapi tsa matsoapong a leoatle ka karolo ea 80 lekholong, ho latela US Federal Aquatic Nuisance Species Species Task Force (ANS).

Libakeng tseo palo ea lionfish e fetohang bothata, mehato e mengata ea taolo e kentsoe ts'ebetsong ho khothaletsa tšebeliso ea tsona (lionfish li bolokehile ho jeoa haeba li lokiselitsoe hantle) ho tšehetsa litlholisano tsa ho tšoasa litlhapi le ho lumella batho ba qoelang ho bolaea lionfish libakeng tsa leoatle. Batho ba qoelang metsing le batšoasi ba litlhapi ba khothaletsoa ho tlaleha ha ba bona lionfish, ’me ba qoelang metsing ba khothaletsoa ho ntša litlhapi ha ho khoneha.

Leha ho le joalo, ha ho na monyetla oa hore lionfish li felisoe ka botlalo sebakeng seo li thehileng baahi ba tsona, ho latela NOAA, kaha mehato ea ho laola e ka 'na ea e-ba e theko e boima haholo kapa e rarahaneng. NOAA e bolela esale pele hore lipalo tsa lionfish Atlantic li ka 'na tsa eketseha.

Bafuputsi ba khothalletsa ho lateloa ha li-lionfish, ho etsa lipatlisiso tse eketsehileng, ho ruta sechaba, le ho theha melao e mabapi le ho lokolla mefuta eo e seng ea tlhaho ea leoatleng e le litsela tsa ho fokotsa ho ata ha lionfish le mefuta e meng e hlaselang.

Bafuputsi le mekhatlo e mengata e hatisa thuto. David Moyer o re: “Hoo e ka bang kamehla mathata a mehleng ea kajeno a ama mefuta ea lintho tse phelang e amahanngoa le mesebetsi ea batho. “Le hoja Motho a se a tlatselitse haholo kabong ea mefuta eohle ea lintho tse phelang lefatšeng lohle, tlhaselo ea tikoloho ha e e-s’o fele ’me ho na le monyetla oa hore letsatsi le leng le le leng ho kenngoe mefuta e mengata e hlaselang lintho tse phelang.”

Maitekong a ho ruta sechaba sebakeng sa DC, 'me ka lebaka la liphallelo tse ngata ho Lefapha la Baeloji ea Estuarine, Setsi sa pokello ea nalane ea Calvert Solomons, MD o tla ba le aquarium ea lionfish karolong ea bona ea Eco-Invaders ka mor'a litokiso tse tlang tsa Estuarium.

"Ho kenyeletsoa le tlhahisoleseling mabapi le bahlaseli ba hona joale le ba kamoso ba tikoloho sebakeng sa rona ho tla ruta baeti ba rona mabapi le hore na mefuta e hlaselang e hlahisoa le ho ata joang," ho boletse Moyer lengolong la lengolo-tsoibila mabapi le ntlafatso e tlang ea pontšo ea Eco-Invaders. "Ka lebaka la sena, ka tšepo batho ba bangata ba tla hlokomela hore na mesebetsi ea bona le likhetho tsa bona li ka ama tikoloho ea bona joang. Kabo ea boitsebiso bona e na le monyetla oa ho thusa ho fokotsa likenyelletso tse sa lakatseheng tsa nakong e tlang.”
