I-Florida crayfish noma i-red marsh crayfish (iProcambarus clarkii) ingeyesigaba se-crustacean.
Ukusabalala komdlavuza waseFlorida.
Umdlavuza waseFlorida uvela eNyakatho Melika. Lezi zinhlobo zisakazeka ezindaweni eziningi eziseningizimu nasenkabeni ye-United States, kanye nasenyakatho-mpumalanga yeMexico (izindawo ezizalelwe kulolu hlobo). I-crayfish yaseFlorida yaziswa eHawaii, Japan kanye noMfula iNayile.
Izindawo zase-Florida crayfish.
I-crayfish yaseFlorida ihlala emaxhaphozini, emifuleni nasemigodini egcwele amanzi. Lezi zinhlobo zigwema imifudlana nezindawo ezisemanzini ezinemisinga enamandla. Ngezikhathi zokoma noma amakhaza, i-crayfish yaseFlorida isinda odakeni olumanzi.
Izimpawu zangaphandle zomdlavuza waseFlorida.
I-crayfish yaseFlorida ingamasentimitha angu-2.2 kuya ku-4.7 ubude. Une-cephalothorax ehlanganisiwe nesisu esihlukanisiwe.
Umbala wekhava le-chitinous muhle, ubomvu kakhulu ngombala, unomugqa omnyama okhonjiwe esiswini.
Ama-specks abomvu abomvu agqamile kuzipho, lolu hlu lombala lubhekwa njengombala wemvelo wemvelo, kepha i-crayfish ingashintsha ubukhulu bembala ngokuya ngokudla. Kulesi simo, kuvela i-blue-violet, i-yellow-orange noma i-brown-green shades. Lapho udla izimbaza, ikhava e-chitinous ye-crayfish ithola amathoni aluhlaza okwesibhakabhaka. Ukudla okunokuqukethwe okuphezulu kwe-carotene kunikeza umbala obomvu obomvu, futhi ukuntuleka kwalesi sigaxa ekudleni kuholela eqinisweni lokuthi umbala we-crayfish uqala ukufiphala futhi ube yithoni ensundu emnyama.
I-crayfish yaseFlorida inesiphetho somzimba esingaphambili esicijile namehlo ahambayo ezihlathini. Njengawo wonke ama-arthropods, anezimbobo zomzimba ezincane kodwa eziqinile, azichitha ngezikhathi ezithile ngesikhathi se-molting. I-crayfish yaseFlorida inamabhangqa ama-5 wemilenze yokuhamba, owokuqala wayo usuphenduke amapincers amakhulu asetshenziselwa ukudla nokuvikela. Isisu esibomvu sihlukaniswe ngezigaba ezincane ezixhunywe ngokuhambisa. Izimpondo ezinde yizitho zokuthinta. Kukhona futhi namabhangqa amahlanu ezinhlinzeko ezincane esiswini, ezibizwa ngokuthi amaphiko. Igobolondo le-crayfish yaseFlorida ohlangothini lwe-dorsal alihlukaniswa yigebe. Ukubhangqa okuvuselelwa kabusha kubizwa ngama-uropods. Ama-Uropods ayisicaba, abanzi, azungeze i-telson, yingxenye yokugcina yesisu. Ama-Uropod nawo asetshenziselwa ukubhukuda.
Ukukhiqizwa kabusha komdlavuza waseFlorida.
I-crayfish yaseFlorida iyanda ekwindla sekwedlule isikhathi. Abesilisa banamasende, imvamisa amhlophe, kuyilapho amaqanda abesifazane enawolintshi. Umanyolo ungaphakathi. Isidoda singena emzimbeni wesifazane ngokuvula okungaphansi kwesibili semilenze yokuhamba, lapho amaqanda efakwa khona. Ngemuva kwalokho i-crayfish yesifazane ilele ngomhlane futhi yakhe umfudlana wamanzi ngamaphiko esisu, athwala amaqanda avundisiwe ngaphansi komphetho we-caudal, lapho ahlala khona cishe amasonto ayisithupha. Ngentwasahlobo, zibonakala njengeziphungumangathi, futhi zihlala ngaphansi kwesisu sowesifazane kuze kube seminyakeni yokuthomba. Lapho zinezinyanga ezintathu ubudala futhi zisesimo sezulu esifudumele, zingazala izizukulwane ezimbili ngonyaka. Izinsikazi ezinkulu ezinempilo zivame ukuzala ama-crustaceans angaphezulu kwama-600.
Ukuziphatha Komdlavuza waseFlorida.
Isici esiphawuleka kakhulu ekuziphatheni kwe-crayfish yaseFlorida yikhono labo lokugoba phansi odakeni.
I-Crayfish icasha odakeni lapho kunokusweleka komswakama, ukudla, ukushisa, ngesikhathi se-molting, futhi ngoba nje banendlela yokuphila enjalo.
I-red marsh crayfish, njengamanye ama-arthropods amaningi, ibhekene nesikhathi esinzima emjikelezweni wabo wokuphila - i-molting, eyenzeka kaningana kukho konke ukuphila kwabo (imvamisa kakhulu i-crayfish molt encane ngesikhathi sebekhulile). Ngalesi sikhathi, baphazamisa imisebenzi yabo ejwayelekile futhi bazingcwaba ngokujule kakhulu. Umdlavuza wakha i-exoskeleton entsha ezacile ngaphansi kwesembozo esidala. Ngemuva kokuthi i-cuticle endala ihlukaniswe ne-epidermis, ulwelwesi olusha oluthambile luyabalwa futhi luqine, umzimba ukhipha amakhemikhali e-calcium emanzini. Le nqubo ithatha isikhathi esiningi.
Lapho nje i-chitin isiqinile, i-crayfish yaseFlorida ibuyela emisebenzini yayo ejwayelekile. Ama-crayfish asebenza kakhulu ebusuku, kanti phakathi nosuku avame ukucasha ngaphansi kwamatshe, izingodo noma izingodo.
Umsoco Womdlavuza waseFlorida.
Ngokungafani nezinye izinhlanzi ezidla uhlaza, i-crayfish yaseFlorida iyizilwane ezidlayo; zidla izibungu zezinambuzane, iminenke kanye nonoshobishobi. Lapho ukudla okuvamile kuyindlala, kudla izilwane ezifile nezibungu.
Okusho umuntu.
I-red marsh crayfish, kanye nezinye izinhlobo eziningi ze-crayfish, kungumthombo obalulekile wokudla kubantu. Ikakhulukazi ezindaweni lapho ama-crustaceans eyisithako esiyinhloko ekudleni okuningi kwansuku zonke. ILouisiana iyodwa inamahektha angama-48,500 amachibi e-crayfish. I-crayfish yaseFlorida yethulwa eJapan njengokudla kwamaxoxo futhi manje seyingxenye ebalulekile yemvelo ye-aquarium. Lolu hlobo luvele ezimakethe eziningi zase-Europe. Ngaphezu kwalokho, i-red marsh crayfish isiza ukulawula iminenke esabalalisa ama-parasites.
Isimo sokulondolozwa komdlavuza waseFlorida.
Umdlavuza waseFlorida unenani elikhulu labantu. Lezi zinhlobo zikwazi ukuphila kahle lapho izinga lamanzi echibini lehla futhi lisinda emigodini elula, engajulile. Umdlavuza waseFlorida, ngokwesigaba se-IUCN, awukhathazeki kangako.
Ukugcina i-crayfish yaseFlorida ku-aquarium.
I-crayfish yaseFlorida igcinwa ngamaqembu ayi-10 noma ngaphezulu ku-aquarium enomthamo wamalitha angama-200 noma ngaphezulu.
Ukushisa kwamanzi kugcinwa kusuka kuma-degree angama-23 kuya kwangu-28, ngamanani aphansi, kusuka kuma-degree angama-20, ukukhula nokuthuthuka nokukhula kwawo kwehla.
I-PH inqunywa kusuka ku-6.7 kuye ku-7.5, ukuqina kwamanzi kusuka ku-10 kuye ku-15. Faka amasistimu wokuhlunga kanye nomoya wemvelo yasemanzini. Amanzi azothathelwa indawo nsuku zonke nge-1/4 yevolumu ye-aquarium. Izitshalo eziluhlaza zingatshalwa, kepha i-crayfish yaseFlorida ihlala iwadla amaqabunga amancane, ngakho ukubukeka komhlaba kubukeka kukubi. Ubulembu namahlathi kuyadingeka ekukhuleni okujwayelekile kwama-crustaceans, athola isiphephelo nokudla ezitshalweni eziminyene. Ngaphakathi, isitsha sihlotshiswe ngenqwaba yezindawo zokukhosela: amatshe, ama-snags, amagobolondo kakhukhunathi, izingcezu ze-ceramic, lapho kwakhiwa khona izindlu zokukhosela ngohlobo lwamapayipi nemigudu.
I-crayfish yaseFlorida iyasebenza, ngakho-ke udinga ukumboza ngaphezulu kwe-aquarium ngesivalo esinezimbobo zokubavikela ekuphunyukeni.
Akufanele nihlalisane ndawonye i-Procambarus crayfish nenhlanzi, indawo enjalo ayivikelekile lapho kwenzeka izifo, ngoba i-crayfish isheshe ithole ukutheleleka bese iyafa.
Kokudla okunomsoco, i-crayfish yaseFlorida ayikhethi, ingaphakelwa izaqathe ezigayiwe, isipinashi esiqoshiwe, izingcezu ze-scallop, izimbaza, izinhlanzi ezondile, i-squid. Ukudla kulekelelwa ngokudla okuphekiwe kwenhlanzi engezansi nama-crustaceans, kanye namakhambi amasha. Njengesengezo samaminerali, kunikezwa ushoki wezinyoni ukuze inqubo yemvelo ye-molting ingaphazanyiswa.
Ukudla okungadliwe kuyasuswa, ukuqoqwa kwemfucumfucu yokudla kuholela ekonakaleni kwemfucumfucu ephilayo namanzi anamafu. Ngaphansi kwezimo ezinhle, i-crayfish yaseFlorida izala unyaka wonke.
