Siab zog attractantsDMPTthiabDMTyog cov tshiab thiab muaj txiaj ntsig zoo rau cov tsiaj hauv dej. Nyob rau hauv txoj kev tshawb no, muaj zog attractantsDMPTthiabDMTtau ntxiv rau carp pub los tshawb xyuas qhov cuam tshuam ntawm ob qho kev nyiam ntawm carp noj thiab txhawb kev loj hlob. Cov txiaj ntsig tau pom tias qhov sib ntxiv ntawm cov muaj zog txaus nyiamDMPTthiabDMTrau qhov pub tau nce qhov zaus ntawm qhov kev sim ntawm cov ntses thiab muaj txiaj ntsig zoo rau kev pub mis; Nyob rau tib lub sijhawm, qhov sib ntxiv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov muaj zog txaus nyiamDMPTthiabDMTrau qhov pub tau nce qhov hnyav nce ntxiv, qhov kev loj hlob tshwj xeeb, thiab muaj sia nyob tus nqi ntawm kev sim ntses, thaum pub coefficient poob qis. Cov txiaj ntsig tshawb fawb kuj qhia tau tiasDMPTmuaj qhov cuam tshuam loj dua rau kev nyiam thiab txhawb kev loj hlob ntawm carp piv rauDMT.

Aquatic tsiaj pub attractant yog ib qho uas tsis yog khoom noj khoom haus additive. Ntxiv cov neeg nyiam noj ntses tuaj yeem txhawb nqa lawv txoj kev noj zaub mov zoo, nce lawv cov zaub mov kom tsawg, txo cov khoom seem hauv dej, thiab txo cov pa phem hauv dej hauv dej.DMPTthiabDMTyog cov tshuaj nquag muaj nyob hauv cov kab mob hauv hiav txwv, ua haujlwm zoo li cov neeg pub dawb methyl thiab tseem ceeb osmotic siab regulators. Lawv kuj muaj qhov tseem ceeb pub noj thiab kev loj hlob txhawb kev cuam tshuam rau cov tsiaj hauv dej.

Tom qab ua cov kev tshawb fawb txog cov tsiaj hauv dej xws li crucian carp, liab snapper, goldfish, thiab pom cw, Japanese cov kws tshawb fawb pom tiasDMPTthiabDMTmuaj txiaj ntsig zoo rau cov dej tshiab thiab cov ntses dej hiav txwv, crustaceans, thiab shellfish. Supplementing tsawg concentrations ntawm high-strength attractantsDMPTthiabDMTnyob rau hauv pub muaj peev xwm heev leeb lub pub thiab kev loj hlob ntawm ntau yam dej qab zib thiab marine ntses. Hauv qhov kev sim no, lub zog muaj zog txaus nyiamDMPTthiabDMTtau ntxiv rau cov khoom noj carp los kawm txog lawv cov teebmeem ntawm kev noj zaub mov carp thiab kev txhawb nqa kev loj hlob, muab cov ntaub ntawv siv rau kev siv dav dav ntawm ob qhov kev nyiam tshiab no hauv kev noj zaub mov thiab kev lag luam aquaculture.

1 Cov ntaub ntawv thiab cov txheej txheem

1.1 Cov ntaub ntawv sim thiab cov ntses sim
S. S' - Dimethylacetic acid thiazole (DMT), DMPT
Cov kev sim carp tau muab los ntawm kev ua liaj ua teb aquaculture, nrog lub cev noj qab haus huv thiab zoo huv si. Ua ntej qhov kev sim pib pib, cov ntses sim yuav tau tsa ib ntus hauv chav kuaj rau 7 hnub, thaum lub sij hawm lawv yuav tsum tau pub nrog carp pub los ntawm lub Hoobkas pub.
1.2 Kev sim pub
1.2.1 Lure test feed: Crush lub carp pub los ntawm lub Hoobkas pub, ntxiv ib qho sib npaug ntawm A-starch, sib tov sib npaug, thiab sib tov nrog ib qho dej distilled kom tsim nyog ua 5g nplaum nplaum txhua qhov raws li pawg tswj hwm pub. Nyob rau tib lub sijhawm, npaj cov ntses pub los ntawm thawj zaug crushing carp pub, ntxiv qhov sib npaug ntawm cov hmoov txhuv nplej siab alpha, thiab ntxiv cov kab DMT thiabDMPTntawm ob qhov concentration ntawm 0.5g / kg thiab 1g / kg, feem. Sib tov sib npaug thiab sib tov nrog qhov tsim nyog ntawm cov dej distilled kom txhua 5g nplaum pob.
1.2.2 Kev ntsuas kev loj hlob:

Sib tsoo carp pub (los ntawm tib qhov chaw raws li saum toj no) rau hauv cov hmoov, hla nws los ntawm 60 mesh sieve, ntxiv ib qho sib npaug ntawm alpha starch, sib tov kom huv si, sib tov nrog dej distilled, nyem nws los ntawm lub sieve rau hauv granules, thiab cua qhuav nws kom tau txais cov pab pawg neeg tswj kev loj hlob mus kuaj. Cov synthesizedDMTthiab DMPT muaju tau yaj hauv cov dej distilled los npaj cov kev daws teeb meem uas tsim nyog, uas yog siv los sib tov cov khoom noj khoom haus zoo sib xyaw thiab cov hmoov txhuv nplej siab rau hauv granules. Tom qab ziab, qhov kev sim pab pawg pub tau txais, nrogDMTthiab DMPT ntxiv rau hauv peb qhov concentration gradients ntawm 0.1g / kg, 0.2g / kg, thiab 0.3g / kg, feem.

1.3 Test Method
1.3.1 Lure test: Xaiv 5 qhov kev sim carp (nrog qhov hnyav nruab nrab ntawm 30g) raws li cov ntses sim. Ua ntej qhov kev sim, tshaib plab rau 24 teev, thiab tom qab ntawd muab cov ntses sim rau hauv ib lub khob thoob dej yug ntses (nrog rau qhov loj ntawm 40 × 30 × 25cm). Lub lure pub yog tsau ntawm qhov deb ntawm 5.0cm los ntawm hauv qab ntawm lub thoob dej yug ntses siv ib txoj kab ncua kev khi rau kab rov tav bar. Cov ntses tom cov kab nuv ntses thiab vibrates txoj kab, uas yog kis mus rau kab rov tav bar thiab kaw los ntawm lub log recorder. Qhov zaus ntawm qhov kev sib tsoo yog xam raws li qhov siab tshaj qhov kev co ntawm 5 kuaj ntses tom cov kab hauv 2 feeb. Kev ntsuam xyuas pub mis rau txhua pab pawg pub tau rov ua dua peb zaug, siv cov pob nplaum uas tau npaj tshiab pub rau txhua lub sijhawm. Los ntawm kev sim rov ua dua kom tau txais tag nrho cov naj npawb thiab qhov nruab nrab zaus ntawm baiting, cov nyhuv pub mis ntawmDMTthiab DMPT ntawm carp tuaj yeem raug soj ntsuam.

1.3.2 Kev loj hlob kev sim siv 8 iav thoob dej yug ntses (qhov loj 55 × 45 × 50cm), nrog rau qhov dej tob ntawm 40cm, dej kub, thiab kev nce nyiaj nce ntxiv. Cov ntses sim tau raug muab faib ua ob pawg rau kev sim. Thawj pab pawg muaj plaub lub thoob dej yug ntses, suav X1 (tswj pab pawg), X2 (0.1gDMT / kg pub), X3 (0.2gDMT / kg pub), X4 (0.3gDMT / kg pub); Lwm pab pawg ntawm 4 thoob dej yug ntses, suav Y1 (tswj pab pawg), Y2 (0.10g DMPT / kg pub), Y3 (0.2g DMPT / kg pub), Y4 (0.30g DMPT / kg pub). 20 ntses rau ib lub thawv, pub 3 zaug hauv ib hnub thaum 8:00, 13:00, thiab 17:00, nrog rau kev pub noj txhua hnub ntawm 5-7% ntawm lub cev hnyav. Qhov kev sim tau siv sijhawm li 6 lub lis piam. Thaum pib thiab xaus ntawm qhov kev sim, qhov ntub dej ntawm qhov ntsuas ntses tau ntsuas thiab qhov ciaj sia taus ntawm txhua pab pawg raug kaw.

2.1 Cov nyhuv pub mis ntawm DMPT thiabDMTpe carp
Kev pub mis ntawm DMPT thiabDMTntawm carp yog tshwm sim los ntawm kev sib tw ntawm cov ntses sim thaum lub sij hawm 2-feeb kev sim, raws li qhia nyob rau hauv Table 1. Qhov kev sim pom tias tom qab ntxiv DMPT thiab DMT pub rau cov thoob dej yug ntses, cov ntses sim tau sai sai pom tus cwj pwm foraging, thaum siv cov tswj pab pawg noj, cov tshuaj tiv thaiv ntawm cov ntses sim tau qeeb. Piv nrog rau kev tswj pub, cov ntses sim tau muaj qhov nce ntxiv hauv qhov zaus ntawm qhov kev sim pub. DMT thiab DMPT muaj qhov ntxim nyiam ntxim nyiam ntawm kev sim carp.

Qhov hnyav nce, qhov kev loj hlob tshwj xeeb, thiab kev ciaj sia ntawm carp pub nrog ntau qhov sib txawv ntawm DMPT tau nce ntau dua piv rau cov pub nrog tswj pub, thaum lub sij hawm pub coefficient tau txo qis. Ntawm lawv, qhov sib ntxiv ntawm DMPT rau T2, T3, thiab T4 tau nce qhov hnyav txhua hnub ntawm peb pawg los ntawm 52.94%, 78.43%, thiab 113.73%, feem, piv rau pawg tswj hwm. Qhov hnyav nce ntawm T2, T3, thiab T4 tau nce 60.44%, 73.85%, thiab 98.49%, feem, thiab cov kev loj hlob tshwj xeeb tau nce los ntawm 41.22%, 51.15%, thiab 60.31%, feem. Cov ciaj sia taus nce los ntawm 90% mus rau 95%, thiab cov khoom noj coefficients poob los ntawm 28.01%, 29.41%, thiab 33.05%, feem.

3. Cov lus xaus

Hauv qhov kev sim no, sebDMTlos yog DMPT tau ntxiv, qhov kev pub noj ntau zaus, qhov kev loj hlob tshwj xeeb, thiab qhov hnyav nce txhua hnub ntawm cov ntses sim hauv txhua pab pawg tau nce ntau dua piv rau pawg tswj hwm, thaum cov khoom noj coefficient poob qis heev. Thiab txawm hais tias nws yog DMT lossis DMPT, qhov kev txhawb nqa kev loj hlob ua qhov tseem ceeb nrog qhov nce ntawm qhov sib ntxiv ntawm peb qhov ntau ntawm 0.1g / kg, 0.2g / kg, thiab 0.3g / kg. Nyob rau tib lub sijhawm, kev sib piv ntawm kev pub mis thiab kev loj hlob txhawb kev cuam tshuam ntawm DMT thiab DMPT tau ua. Nws tau pom tias nyob rau hauv tib qhov kev txiav plaub hau, kev pub noj ntau zaus, qhov hnyav nce, thiab qhov kev loj hlob tshwj xeeb ntawm cov ntses sim hauv pawg DMPT pub tau nce ntau dua piv rau DMT pub pab pawg, thaum lub sij hawm pub coefficient tau txo qis. Hais txog hais lus, DMPT muaj qhov cuam tshuam loj dua rau kev nyiam thiab txhawb kev loj hlob ntawm carp piv rau DMT. Qhov kev sim no siv DMPT thiab DMT ntxiv rau carp pub los tshawb txog lawv cov kev pub noj thiab kev loj hlob txhawb kev loj hlob. Cov txiaj ntsig tau pom tias DMPT thiab DMT muaj cov ntawv thov dav dav raws li lub cim tshiab ntawm cov tsiaj hauv dej.
