Usoro molting nke oporo bụ ọkwa dị mkpa na uto na mmepe ha. N'oge uto nke oporo, ka ahụ ha na-eto eto, shei ochie ga-egbochi uto ha n'ihu. Ya mere, ha kwesịrị ịnata molting na-etolite ọhụrụ na ibu shei. Usoro a na-achọ oriri ume ma nwee ụfọdụ ihe ndị na-edozi ahụ, dị ka mineral dị ka calcium na magnesium, nke a na-eji maka ịmepụta na ike siri ike nke shei ọhụrụ; na ụfọdụ ihe na-akwalite uto ma na-achịkwa ọrụ physiological dịkwa mkpa iji hụ na ọganihu dị mma nke usoro molting.
DMTbụ ligand dị irè maka ndị na-anabata ihe ụtọ mmiri, nke nwere mmetụta na-akpali akpali siri ike na uto na irighiri irighiri akwara nke anụmanụ mmiri, si otú a na-eme ka ọsọ nke nri anụ mmiri na-eri nri ma na-amụba nri nri ha n'okpuru ọnọdụ nrụgide. Ka ọ dị ugbu a, DMT nwere mmetụta ịkpụzi-dị ka ọrụ, nke nwere ike ịkpụzi-dị ka ọrụ, nke nwere ike bulie molting ọsọ nke oporo na crab,karịsịa na etiti na nke ikpeazụ nke oporo na nshịkọ ugbo, mmetụta a na-apụta ìhè karị
1. DMPT (Dimethyl-β-propiothetin)
Ọrụ igodo
- Ihe na-adọta nri siri ike: na-akpali agụụ nke azụ, oporo, crabs na ụdị mmiri ndị ọzọ, na-eme ka nri nri dịkwuo mma.
- Nkwalite uto: Otu nwere sọlfọ nwere (-SCH₃) na-eme ka njikọ protein dịkwuo elu, na-eme ka ọnụ ọgụgụ na-eto eto dịkwuo elu.
- Mmalite mma anụ: na-ebelata ntinye abụba ma na-abawanye amino acid umami (dịka ọmụmaatụ, glutamic acid), na-eme ka ụtọ anụ ahụ dịkwuo mma.
- Mmetụta mgbochi nrụgide: na-akwalite nnabata na nrụgide gburugburu ebe obibi dị ka hypoxia na mgbanwe salinity.
Ụdị ebumnuche
- Azụ (dịka ọmụmaatụ, azu kaapu, crucian azu kaapu, oké osimiri bass, nnukwu odo croaker)
- Crustaceans (dịka, oporo, crabs)
- Kukumba oke osimiri na mollusks
Ngwọta akwadoro
- 50-200 mg / kg nri (gbanwee dabere na ụdị na ọnọdụ mmiri).
2. DMT (Dimethylthiazole)
Ọrụ igodo
- Mmasị nri na-agafeghị oke: Na-egosi mmetụta na-adọrọ adọrọ maka azụ ụfọdụ (dịka ọmụmaatụ, salmonids, bass osimiri), n'agbanyeghị na esighi ike karịa DMPT.
- Njirimara Antioxidant: Ọdịdị thiazole nwere ike melite nkwụsi ike nke nri site na ọrụ antioxidant.
- Mmetụta nje nwere ike ime: Nnyocha ụfọdụ na-egosi na ihe ndị thiazole na-emepụta na-egbochi nje nje.
Ụdị ebumnuche
- A na-eji ya eme ihe na nri azụ, ọkachasị maka ụdị mmiri oyi (dịka ọmụmaatụ, salmon, trout).
Ngwọta akwadoro
- 20-100 mg/kg nri (usoro kachasị mma chọrọ nkwado ụdị-kpọmkwem).

Ihe ndetu maka ngwa
- DMPT dị irè karị mana ọnụ ahịa; họrọ dabere na mkpa ugbo.
- DMT chọrọ nyocha n'ihu maka mmetụta ndị akọwapụtara ụdị.
- Enwere ike ijikọ ha abụọ na mgbakwunye ndị ọzọ (dịka ọmụmaatụ, amino acids, bile acids) iji kwalite arụmọrụ.
