Shrimp ya Amano (Caridina multidentata) ndi ya gulu la crustacean. Mitunduyi nthawi zambiri imatchedwa AES (Algae Eating Shrimp) - "nsomba zam'nyanja" shrimp. Takashi Amano, wopanga zinthu zaku Japan, amagwiritsa ntchito nkhanuzi m'malo opangira zinthu kuti athetse ulusi m'madzi. Chifukwa chake, idatchedwa Amano Shrimp, pambuyo pa wofufuza waku Japan.
Zizindikiro zakunja kwa Amano shrimp.
Shrimp za Amano zimakhala ndi mawonekedwe obiriwira owoneka bwino, okhala ndi mawanga ofiira ofiira m'mbali (0,3 mm kukula), omwe amasanduka mikwingwirima yapakatikati. Mzere wopepuka umawonekera kumbuyo, womwe umayambira kumutu mpaka kumapeto kwa caudal. Akazi okhwima ndi okulirapo, amakhala ndi thupi lokwanira masentimita 4 - 5, pomwe amabala ena ataliatali amadziwika. Amuna amadziwika ndi mimba yopapatiza komanso yaying'ono. Mtundu wa chivundikiro cha chitinous umatsimikizika ndi kapangidwe ka chakudyacho. Zinyama zomwe zimadya algae ndi detritus zimakhala ndi ubweya wobiriwira, pomwe zomwe zimadya chakudya cha nsomba zimakhala zofiira.
Amano shrimp amafalikira.
Amano shrimp amapezeka mumitsinje yamapiri yokhala ndi madzi ozizira, kumwera chakumwera kwa Japan, komwe kumadutsa kunyanja ya Pacific. Amagawidwanso kumadzulo kwa Taiwan.
Chakudya cha shrimp cha Amano.
Amano shrimp amadya algal fouling (filamentous), idyani detritus. Mu aquarium, amadyetsedwa ndi chakudya chouma cha nsomba, nyongolotsi zazing'ono, brine shrimp, cyclops, zukini wosweka, sipinachi, magazi a mphutsi. Ndikusowa kwa chakudya, Amano shrimp amadya masamba achichepere am'madzi. Chakudya chimaperekedwa kamodzi patsiku, chakudya sichiloledwa kukhazikika m'madzi kuti tipewe kuipitsidwa kwa madzi a m'nyanja.
Tanthauzo la shrimp Amano.
Amano shrimp ndizofunikira kwambiri pakutsuka zam'madzi kuchokera pakukula kwa algal.
Makhalidwe a Amano shrimp.
Amano shrimp amasinthidwa kukhala malo awo ndikukhala mozungulira pakati pazomera zam'madzi. Komabe, ndizovuta kuzizindikira. Nthawi zina, pomwe amadzi am'madzi, osapeza nkhono m'madzi, aganiza kuti nyama zakutchire zafa ndikuthira madziwo, ndipo nkhanu zosowa zimapezeka mwadzidzidzi m'malo otsika.
Nkhono za Amano zimabisala m'nkhalango zowirira za m'madzi okhala ndi masamba ang'onoang'ono, momwe zimamvera kuti ndi zotetezeka. Amakwera pansi pamiyala, mitengo yolowerera, amabisala m'malo aliwonse obisika. Amakonda kukhala m'madzi othamanga ochokera mufyuluta ndikusambira motsutsana ndi pano. Nthawi zina shrimp imatha kutuluka m'madzi (nthawi zambiri usiku), chidebe chomwe chimakhala ndi nkhono chimatsekedwa mwamphamvu, ndipo njira yosamalira aquarium imayikidwa kuti ma crustaceans asakwerepo. Khalidwe losavomerezeka ngati ili likuwonetsa kuphwanya malo am'madzi: kuwonjezeka kwa pH kapena mulingo wama protein.
Momwe mungasungire shrimp Amano mu aquarium.
Shrimp za Amano sizikakamira kuti zisunge. Gulu laling'ono la nsomba limatha kusungidwa m'madzi okwanira 20 malita. Kutentha kwamadzi kumasungidwa pa 20-28 madigiri C, PH - 6.2 - 7.5, malinga ndi malipoti ena, ma crustaceans samachita manyazi ndi kuchuluka kwa zinthu zam'madzi.
Shrimps za Amano zimasungidwa pamodzi ndi mitundu yaying'ono ya nsomba zam'madzi, koma zimabisala m'nkhalango kuchokera kumalo omata. Muyenera kudziwa kuti mitundu ina ya nsomba, mwachitsanzo, zikopa, zimadya nkhanu. Nsombazo sizowopsa kwa anthu ena okhala m'nyanjayi. Ali ndi zikhadabo zochepa zomwe ndizoyenera kuthyola ndere zazing'ono. Nthawi zina nkhonoyi imanyamula chakudya chokulirapo ndikukulunga miyendo yake ndikuchithandiza kuyenda ndi mchira wake.
Kuswana Amano Shrimp.
Amano shrimp nthawi zambiri amakodwa kuthengo. Mu ukapolo, ma crustaceans samabereka bwino kwambiri. Komabe, n`zotheka kupeza ana a nkhanu mu aquarium ngati zinthuzo zikuwonetsedwa. Mkaziyo amakhala ndi mphalapala lalitali komanso thupi lokhazikika m'mbali mwake. Mutha kudziwa zachiwerewere ndi zikhalidwe za mzere wachiwiri wa mawanga: mwa akazi amatalikirana, ofanana ndi mzere wosweka, mwa amuna, mawanga amafotokozedwa bwino, mozungulira mawonekedwe. Kuphatikiza apo, akazi okhwima mwakugonana amadziwika ndi kupezeka kwamapangidwe apadera - "chishalo", pomwe mazira amapsa.
Kuti apeze ana athunthu, shrimp ayenera kudyetsedwa kwambiri.
Mzimayi amakopa wamwamuna kuti akwere, amatulutsa ma pheromone m'madzi, champhongo choyamba chimasambira mozungulira, kenako chimatembenuka ndikuyenda pansi pamimba kuti atulutse umuna. Kulumikizana kumatenga masekondi ochepa. Pamaso pa amuna angapo, kuswana kumachitika ndi amuna angapo. Masiku angapo pambuyo pake, yaikazi imabereka ndi kumamatira pansi pamimba. Mkazi amatenga "thumba" lokhala ndi caviar, momwe mumakhala mazira zikwi zinayi. Mazira omwe akukulawo ndi obiriwira achikasu ndipo amawoneka ngati moss. Kukula kwa mazirawo kumatenga milungu inayi kapena isanu ndi umodzi. Mkazi amasambira m'madzi okhala ndi mpweya wokwanira wokwanira m'madzi, amatsuka ndikusuntha mazira.
Masiku angapo mphutsi zisanawonekere, mazira amawala. Munthawi imeneyi, maso a mazira omwe akukula amatha kuwonedwa m'mazira ndi galasi lokulitsa. Ndipo kumasulidwa kwa mphutsi kumatha kuyembekezeredwa m'masiku ochepa, nthawi zambiri kumachitika usiku osati nthawi imodzi. Mphutsi zimawonetsa phototaxis (zabwino zomwe zimachitika pakuwala), choncho zimagwidwa usiku, zimaunikira nyanjayi ndi nyali, ndipo zimayamwa ndi chubu. Ndi bwino kubzala mkazi woberekera nthawi yomweyo mosungira chidebe, nkhanu zazing'ono zimakhala zotetezeka.
Mphutsi zikangotuluka, chachikazi chimabwezeretsedwera ku aquarium yayikulu. Pakapita kanthawi, amakwatiranso, kenako amasungunuka, ndikunyamula gawo lina latsopano la mazira.
Mphutsi zoswazo ndi za 1.8 mm kutalika ndipo zimawoneka ngati utitiri tating'ono ta m'madzi. Amakhala ngati zamoyo zam'madzi ndipo amasambira ndimiyendo yawo atapanikizika ndi thupi. Mphutsi zimasunthira chotsika ndipo pambuyo pake zimangokhala malo osanjikiza, koma thupi limakhala lopindika.
Akuluakulu Amano shrimp m'chilengedwe amakhala mumitsinje, koma mphutsi zomwe zimawoneka zimanyamulidwa ndi zomwe zikupita kunyanja, zimadya plankton ndikukula msanga. Pambuyo pomaliza kusintha, mphutsi zimabwerera kumadzi abwino. Chifukwa chake, pobzala nsomba za Amano mumtsinje wa aquarium, m'pofunika kukumbukira momwe zinthu zingapangire mphutsi, tsiku lachisanu ndi chitatu zimayikidwa m'nyanja yamadzi yokhala ndi madzi osefera achilengedwe okhala ndi mpweya wabwino. Pankhaniyi, mphutsi zimakula mofulumira ndipo sizifa.
