Shrimp yakumpoto yakumpoto (Pandalus borealis) ndi ya gulu la nkhono. Ndi mitundu yozizira yam'madzi ozizira yomwe ndi yofunika kwambiri pamalonda.
Malo okhala kumpoto kwa pinki shrimp.
Shrimp yakumpoto yakumpoto amakhala pansi pa 20 mpaka 1330 mita. Amakhala panthaka yofewa komanso yolimba, m'madzi am'nyanja otentha kuyambira 0 ° C mpaka +14 ° C ndi mchere wa 33-34. Pakuya mamita mazana atatu, nkhanu zimapanga masango.

Zizindikiro zakunja kwakumpoto kwa pinki.
Shrimp yakumpoto ya pinki yasintha posambira m'mbali yamadzi. Ili ndi thupi lalitali, lopanikizika m'mbali, lopangidwa ndi magawo awiri - cephalothorax ndi pamimba. Cephalothorax ndi yayitali, pafupifupi theka la kutalika kwa thupi. Pali diso limodzi m'matumba amkati amphongo. Maso ndi ovuta ndipo amakhala ndi mbali zambiri zosavuta, kuchuluka kwake kumakulirakulira. Maso a Shrimp ndi ojambula, pomwe chithunzi cha chinthu chimapangidwa ndi zithunzi zambiri zomwe zimawoneka pagulu lililonse. Masomphenya oterewa owazungulira siowonekera bwino komanso osamveka bwino.
Katundu wonenepa kwambiri ndi chitetezo chodalirika cha mitsempha; pansi pake imakhala yopyapyala.
Shrimp yakumpoto yakumpoto ili ndi mapaundi 19 amiyendo. Ntchito zawo ndizosiyana: tinyanga ndi ziwalo zovuta kukhudza. Mandibles kuphwanya chakudya, nsagwada kugwira nyama. Miyendo yayitali, yokhala ndi zikhadabo zazing'ono, imasinthidwa kuti izitsuka thupi ndi mitsempha kuchokera ku kuipitsidwa ndi ma silt. Miyendo yonseyo imagwira ntchito yamagalimoto, ndi yayitali kwambiri komanso yamphamvu kwambiri. Miyendo yam'mimba imathandizira kusambira, koma m'nkhono zina zasandulika (mwa amuna), mwa akazi amatumizira kubereka mazira.
Makhalidwe apadera a nkhanu zakumpoto zapinki.
Shrimpi wakumpoto wakumadzi m'madzi amakhudza pang'onopang'ono miyendo yawo, mayendedwe oterewa sali ngati kusambira. Ochita nkhandwe mwamantha amalumpha mwachangu mothandizidwa ndi kupindika kwakuthwa kwa chimbudzi champhamvu kwambiri. Njirayi ndi chitetezo chofunikira pakulimbana ndi adani. Kuphatikiza apo, nkhanu zimalumpha chammbuyo chokha, ndiye kuti ndizosavuta kuzigwira mukabweretsa ukondewo kumbuyo, ndikuyesera kuugwira kutsogolo. Zikatero, nkhonoyi imadzilumphira yokha muukonde popanda kuwononga thupi.
Kubalana kwa shrimp wakumpoto pinki.
Shrimp yakumpoto yakumpoto ndizamoyo zedioecious. Ndi ma protrandric hermaphrodites ndipo amasintha kugonana atakwanitsa zaka zinayi. Pambuyo pomaliza kukula kwa mphutsi, nkhanuzo zikafika zaka 1.5, zimakhala zazimuna. Ndiye pali kusintha kosintha kwa nkhono ndipo shrimp imaberekanso ngati akazi. Amamangiriza mazira m'miyendo yam'mimba yomwe ili pamimba.
Kukula kwakumpoto kwa pinki kumachitika mwachindunji kapena pakusintha, pamenepa mphutsi zimatuluka.
Fodya woyamba amatchedwa nauplius; amadziwika ndi kupezeka kwa miyendo itatu yamiyendo ndi diso limodzi lopangidwa ndi ma lobes atatu. Fomu yachiwiri - protozoa ili ndi mchira ndi njira ziwiri (imodzi ndi yofanana ndi mlomo, yachiwiri ili ngati munga). Pakukula mwachindunji, kanyama kakang'ono kakang'ono kamodzi kamatuluka m'dzira. Akazi amanyamula ana kwa miyezi 4-10. Mphutsi zimasambira kwakanthawi kwakanthawi pang'ono. Pambuyo pa miyezi 1-2 imamira pansi, ndi nkhanu zazing'ono kale, ndikukula msanga. Molt imachitika nthawi ndi nthawi mu ma crustaceans. Munthawi imeneyi, chivundikiro chakale cholimba chimasinthidwa ndi chofewa chodzitchinjiriza, chomwe chimangotambasulidwa mosavuta atangosungunuka.
Kenako imaumitsa ndi kuteteza thupi lofewa la nkhanuyo. Pamene crustacean imakula, chipolopolocho chimayamba kuchepa, ndipo chivundikirocho chimasinthanso. Pakati pa kusungunula, shrimp yakumpoto ya pinki imakhala pachiwopsezo chachikulu ndipo imakonda nyama zambiri zam'madzi. Shrimpi wakumpoto wakumpoto amakhala munyanja pafupifupi zaka 8, mpaka kutalika kwa thupi kwa 12.0 -16.5 cm.
Kudyetsa Nkhanu Yakumpoto ya Pinki.
Shrimp wakumpoto amadya detritus, zomera zakufa zam'madzi, nyongolotsi, tizilombo, ndi daphnia. Amadya mitembo ya nyama zakufa. Nthawi zambiri amasonkhana m'magulu akulu pafupi ndi maukonde ndipo amadya nsomba zokodwa m'maselo aukondewo.
Mtengo wamalonda wa nkhanu zakumpoto zapinki.
Shrimp yakumpoto yakumpoto imawedza kwambiri, ndikugwira matani mamiliyoni angapo pachaka. Makamaka kupha nsomba mwamphamvu kumachitika m'madzi a Nyanja ya Barents. Nkhono zazikuluzikulu zam'madzi zimapezeka m'malo omwe ali kumpoto chakum'mawa kwa Victoria Island.
Masheya amtundu wa crustaceans mu Nyanja ya Barents ali pafupifupi matani 400-500 zikwi.
Zinyama zapinki zakumpoto zimakopanso nsomba kumadzulo kwa Atlantic ndi North Atlantic, ndi malo akuluakulu osodza pafupi ndi Greenland ndipo tsopano agwidwa kumwera chakumwera ku Gulf of St. Lawrence, Gulf of Fundy ndi Gulf of Maine. Pali nsomba zambiri m'dera la Iceland komanso m'mphepete mwa nyanja ya Norway. Shrimp yakumpoto ya pinki imapanga 80 mpaka 90% ya nsomba kugombe lakumadzulo kwa Kamchatka, Bering Sea ndi Gulf of Alaska. Shrimp yamtunduwu imasodzedwa ku Korea, USA, Canada.
Zopseza ku Northern Pink Shrimp.

Pakadali pano, zombo zaku Russia ndi Norway zikusodza m'dera la Spitsbergen pansi pa layisensi yapadera yomwe imayang'anira kuchuluka kwa masiku ogwira ntchito ndi kuchuluka kwa zombo.
Komanso, kukula kwa mauna osachepera ndi 35 mm. Pofuna kuchepetsa nsomba, kutsekedwa kwakanthawi kwa malo ophera nsomba komwe kuli ma haddock, cod, halibut wakuda ndi redfish kukuchitika.
Nsomba za shrimp m'dera loteteza asodzi ku Svalbard zimayang'aniridwa nthawi zonse chifukwa chodandaula kuti nkhono zakumpoto zapinki zitha. Dziko lililonse limapatsidwa masiku angapo asodzi. Kutalika kwamasiku omwe agwiritsidwa ntchito posodza kwachepetsedwa ndi 30%.
