Crayfish: ʻike pono no ka lawaiʻa
ʻO ka iʻa maʻamau ma ʻEulopa a me Rūsia, loaʻa kekahi mau ʻano. ʻO lākou a pau he mau ʻelele o ka pūʻulu decapods. He uhi chitinous ko nā holoholona ma ke ʻano he iwi waho. ʻIke ʻia ka hiʻohiʻona o ka crayfish, ma ke ʻano he kānāwai, he ʻōmaʻomaʻo ʻōmaʻomaʻo ka waihoʻoluʻu, kahi e ʻike ʻole ʻia ai i ke kua o lalo. Makemake ʻo Crayfish i nā kino wai me ka hoʻololi ʻana o ka oxygen maikaʻi, inā aia lākou i ka stagnant a i ʻole ke kahe lohi, ʻoi aku hoʻi ma nā ʻāpana hema, pili lākou i nā wahi e puka ai ka wai honua. Noho lākou ma kahi ākea o ka hohonu, ma lalo o nā kūlana pōʻino a inā pilikia paha lākou e peʻe i loko o nā lua i ʻeli ʻia a i ʻole ma lalo o nā pōhaku, a pēlā aku. ʻO nā mea kanu ka 90% o kā lākou meaʻai; ʻai lākou i nā holoholona a me nā kupapaʻu i kēlā me kēia manawa. Hoʻoulu nui ʻia ke ʻano honi. ʻAʻole hiki ke kapa ʻia lākou he holoholona aloha anu, akā hana lākou i ka hoʻoilo. Holo mua ke poʻo, ʻauʻau i hope. ʻO ka nui o ka nui o nā ʻano āpau mai 20-30 cm. Pilikia ka i'a i ka ma'i ahulau, ke ahulau o ka i'a, no laila, hiki ke kakaikahi a kakaikahi paha ka hoolaha ana, aka, ma kekahi mau wai, ua nui loa ia mau mea e hiki ai ke lilo i mea hooweliweli i na mea e ae. Pono e hoʻomanaʻo ʻia ma ka hapa nui o nā wahi o Rūsia, ua hoʻoponopono ʻia ka ʻili ʻana o nā crustaceans wai e ke kānāwai a i pāpā ʻia paha. Ma mua o ka hopu ʻana i ka iʻa, e nānā i nā lula no ka ʻohi ʻana i kēia holoholona.
Nā ala e hopu ai i ka ʻuʻuku
ʻOiai nā pilikia me nā maʻi a me ka maʻi ahulau, hiki i ka crayfish ke lilo i mea maikaʻi loa no ka lawaiʻa ʻana, akā he "hoa maikaʻi ʻole" lākou o nā lawaiʻa, wehe lākou i ka maunu mai nā makau, ʻai i ka maunu, ʻaʻole kōkua ka hoʻohana ʻana i nā boilies paʻakikī. I ka hoʻoilo, i ka lawaiʻa hau, hiki iā lākou ke hele mai ma luna o nā mormyshkas wale nō, akā ma nā spinners a me nā mea kaulike. ʻAʻole naʻe lākou e hopu pono i ka iʻa me nā koʻokoʻo. ʻO ke ala maʻamau e ʻohi ai i ka iʻa he pāpaʻi a me ka ʻupena. Mai ka wā kahiko, hiki iā ʻoe ke inoa i ka mea pio me ke kōkua o kahi "ihe" - he lāʻau lōʻihi, ʻo ka ʻaoʻao kikoʻī o ia mea i māhele ʻia a wili. I ka wai pāpaʻu, i ka pō, hiki ke ʻohi lima ʻia ka crayfish. Pono kēia i kahi kukui uila. Inā loaʻa ka iʻa ma nā kahawai liʻiliʻi a i ʻole nā kahawai, a laila hiki iā ʻoe ke hōʻiliʻili iā lākou i ka lā ma lalo o nā pōhaku a me nā snags. He hana hoihoi kēia, akā "pilikia". Eia kekahi, ʻeli ʻia ka crayfish ma ka hohonu me ka hoʻohana ʻana i kahi mask a me kahi snorkel luʻu. ʻO kekahi ala leʻaleʻa e hopu ai i ka crayfish ʻo ka haʻi ʻana i ka "boot fishing". Hoʻokomo ʻia kahi maunu i loko o ka pahu, a hāʻule i lalo me ke kōkua o ke kaula. Puka mai ma hope o kekahi manawa. Pono e kolo ka iʻa i loko o ka bootleg a lawe ʻia e ka mea hahai holoholona.
Maunu
I ka lawaiʻa ʻana me ke kōkua o nā iʻa like ʻole, pono ka maunu. Hiki ke hoʻohana ʻia kēlā me kēia ʻiʻo, loko o nā holoholona, a i ʻole nā iʻa popopo.
Nā wahi lawaiʻa a me nā wahi noho
ʻO ka hapa nui o ka Russian Federation, ʻo Siberia hoʻi, he home ia no nā ʻuala haiki. ʻOi aku ka liʻiliʻi o ka crayfish ma Rusia, ʻoi aku ka nui ma ke kahawai ʻo Baltic Sea. ʻAʻole pili kēia mau iʻa i ka noho ʻana o kekahi i kekahi, akā ʻoi aku ka nui o nā ʻāina i hopu ʻia e ka ʻuala haiki. Hoʻopili ʻia ka puʻunaue nui ʻana o nā ʻuʻu liʻiliʻi me ka ʻoi aku ka maikaʻi o ka hoʻololi ʻana o ia ʻano. Malia paha, noho ka i'a haiki wawae i ka 'āina kahi i nalowale ai ka i'a ma muli o ke ahulau. Ua manaʻo ʻia i ka wā ma mua, ua puʻunaue ʻia ka wāwae haiki mai ke kai Caspian. Ma ʻEulopa, ua hopu ʻia ka wahi o ka puʻunaue ʻana i nā iʻa ākea ākea e kekahi ʻano ʻē aʻe, he mea hoʻouka kaua - ʻo ka crayfish hōʻailona ʻAmelika. Ma ka mokuna o Rusia, ua loaʻa ia ma ka mokuʻo Kaliningrad. Ma ka Hikina Hikina, ma ke kahawai ʻo Amur River, ola kekahi ʻano iʻa (genus Cambaroides).
ʻOhana
Hiki ke oʻo ka iʻa i ka makahiki 3-4 makahiki. ʻO ka fertilization i loko o ka crayfish no loko, ma muli o ke ʻano anatomical a me ka huhū o nā kāne, pono e hoʻokō ʻia kekahi mau kūlana no ka hoʻohua maikaʻi ʻana. ʻO ka mea mua, ʻoi aku ka nui o ke kāne ma mua o ka wahine, i ʻole e pakele ka wahine. Makaʻu nā wahine i nā kāne a pale aku i ka launa pū ʻana me lākou, no laila e hana ʻino loa nā kāne a hiki ke hahau nui i nā wahine. Hoʻopili nā kāne nui i nā manawa he nui, ma hope o ka hoʻoulu ʻana, hiki i ke kāne, no ka pōloli, ke ʻai i ka wahine hope loa. Ma hope o ka male ʻana, ʻaʻole hiki i nā wahine ke haʻalele i ko lākou mau lua a i ʻole nā hale noho no ka manawa lōʻihi, no ka makaʻu i nā kāne, ka mea e hoʻopilikia ai i ka ea o nā hua, a make paha. ʻEkolu pule ma hope o ka hoʻopōmaikaʻi maikaʻi ʻana, hiki mai ka spawning. Hoʻopili ʻia nā hua i nā prolegs o ka wahine a waiho ʻia ma laila a hiki i ka hāʻule ʻana o ke ʻano. Hoʻomaka ke ola kūʻokoʻa o nā larvae ma hope o ʻelua mahina.
